CHAPTER 1
INTRODUCTION TO THE TWELFTH REPORT OF THE
MOOR GREEN LAKES GROUP
Peter
Scott
In last
year’s introduction I mentioned that some of the ‘infrastructure’ of the
reserve, such as fences, was showing its age and needed a substantial input
of effort and money. Also, vegetation growth was spoiling certain habitats,
notably the scrapes. I never expected that, just one year later, we would
have made such improvements in these areas.
That we have
done so is almost entirely due to our good fortune in being able to use a
grant from the Aggregates Levy Sustainability Fund (ALSF) to employ
contractors. Sue Dent describes the work done with this grant, as well as
our usual work programme, in chapter 2. Sue is unduly modest about her own
contribution to this work. The ALSF money would not have been used so
productively without her efforts in drawing up job descriptions, liaising
with bidders and letting the contracts.
RMC Materials
Ltd., the site owner, was taken over during the year by CEMEX, a
Mexican-owned cement and aggregates company, which is why this new name
appears at various points in the report. The company is currently is in a
state of flux while the new managers familiarise themselves with British and
European regulations and working practices. We must hope that their
commitment to the reserve will not be diminished.
One task that
CEMEX has completed during the year is the replacement of sluices, etc, for
the control of water flow through the lakes. We are optimistic that the
improvements, together with the work carried out with the ALSF grant, will
help us to maintain habitat quality, particularly for wading birds around
the scrapes.
During the
year, Chris Rose resigned from the post of treasurer after many years of
service to the group (having also been membership secretary in earlier
years). Bruce Archer has stepped into this role. Chris has kindly agreed to
continue to collate our annual report for the time being. Sheila Farmer
resigned as membership secretary at the end of the year after three years in
the post, and Katrina Slocombe relinquished the role of mammal recorder.
Brendan McCartney and Ian White have come forward as their respective
replacements. We are grateful to all of them for their work on our behalf,
both past and present.
Our wildlife
recorders have done their usual thorough (and often time-consuming) job of
producing the various chapters of this report, which presents a picture of
the reserve maintaining its place as a valuable ‘home’ for numerous species.
The changes over the years in the relative numbers of different species make
fascinating reading. I hope you will find it interesting and enjoyable.

CHAPTER 2
SITE MANAGEMENT REPORT, APRIL 2004 TO MARCH
2005
Sue Dent,
Blackwater Valley Countryside Partnership
It has been
very busy and exciting year at Moor Green. As well as our regular site
management tasks, the site has benefited from an Aggregates Levy
Sustainability Fund (ALSF) grant. Keeping up with the regular tasks while
planning and implementing the grant work was quite a challenge but one that
the team at Moor Green has risen to - admirably. I would like to start by
thanking everyone who has contributed this year: the Moor Green Lakes Group
committee and volunteers for all their hard work; CEMEX for their backup,
support and finance and the users of the site for their patience and
forbearance. I hope that the extra work didn’t spoil your enjoyment of the
reserve: it should be very beneficial in the long run.
Site
Management
Thanks also
to the volunteers who help to organise and run the tasks, especially Peter
Scott for his help with planning and scheduling tasks and to Peter, Simon
Weeks and Tony Elston for leading the Sunday tasks. In recent years Steve
Farmer has done excellent job of recruiting volunteers and encouraging
people to turn up on the day. He has now handed over the reins to Simon
Weeks who is carrying on the good work.
-
Winter
Site Maintenance.
On the grassland and lake edges small trees and scrub were cleared to
maintain the open aspect around the lakes. Last winter the bramble, which
was encroaching from the northern edge of the site, was cut by
contractors. This had grown back with great vigour but the volunteers were
able to clear the re-growth and we hope that by cutting this every 1 or 2
years we should be able to keep it under control and stop it spreading
further into the grassland.
Tern and
Plover Islands were cleared as usual and a start was made on reducing the
amount of bramble and scrub on Long Island.
-
Crassula. The
Crassula in the scrape outside Colebrook hide, which was sprayed with
herbicide in 2003, didn’t come back to its former extent. In the summer
the scrape contained a mixture of plant species rather than a monoculture
of Crassula showing that, if conditions are good, it is possible to
control if not eradicate Crassula by spraying. The scrape was re-modelled
as part of the ALSF grant work and was largely scraped clean of vegetation
so we will be monitoring the return of the Crassula with interest.
Finally thanks to everyone who keeps an eye on
the reserve and lets us know if things are amiss or cattle are straying. It
is much appreciated and a great help. Please keep in touch.
AGGREGATES LEVY SUSTAINABILITY FUND GRANT
Sue Dent,
Blackwater Valley Countryside Partnership
This year
Moor Green Lakes Nature Reserve received a grant for £38,000 for habitat and
access improvements on the site.
The funding
was part of a grant from the Aggregates Levy Sustainability Fund (ALSF)
which supports projects that benefit areas that have been affected by
mineral extraction. The funding for Moor Green is part of a grant entitled
‘Building for Nature’, which was awarded to the SouthEast England
Development Agency (SEEDA). As well as the practical work at Moor Green the
grant included the development of a web site on Mineral Extraction and
Biodiversily which can be found at
www.mineralbap.com.
Overall the
grant has given us an opportunity to tackle some large jobs on the reserve,
invest in infrastructure and make substantial improvements both to the
habitats of the reserve and the access to it.
HABITAT
1.
Bridge to Long Island
Top of the reserve ‘wish
list’ was a connection between Long Island and the mainland. Being so big it
has been practically impossible to manage Long Island in the way we would
like with access only by boat. In particular it isn’t possible to get any
large machinery onto the island. Putting a bridge in at the eastern end of
the island was considered but we were concerned about putting in a permanent
access to the island. It was decided to purchase a pontoon system that would
span the gap but that we could move at the end of each work session and moor
by the island.
The pontoon is 12 metres
long and made of 54 ‘Cubisystem’ modular blocks. It gives a good stable
access and has already demonstrated its value in facilitating work on Long
Island. It is hoped that it will also be possible to use the pontoon for
access to Plover and Goose Islands.
2.
Ditches and Scrapes
Grove
Scrapes
Since it was created in
1997 the scrape outside Grove Hide has very much split into 2 halves. The
southern end has gradually covered with vegetation (not ideal for bird
watching) while the northern half has remained bare, largely because the
water in it has been found to have roughly the pH of lemon juice (and hence
contains little food for wading birds).
The two halves of the
scrape have been separated from each other with a bund. The level of the
northern half has been lowered and two gaps have been made in the bund
separating it from the lake. This has allowed water to flood the scrape and
has already substantially raised the pH. Most of the vegetation has been
removed from the southern half of the scrape.
Colebrook Scrape
The scrape outside of
Colebrook Hide had gradually become dominated by vegetation that it was
impossible to control by hand. It was also felt that creating a greater
variety of water depths and a number of small islands rather than one long
bund would increase the value of the scrape for feeding birds. All
vegetation was removed from the surface of the scrape and bunds, and the
main bund between the scrape and the lake was broken up into three islands.
The scrape was also widened and a further island created in the centre.
Long
Island
Using our new access to
Long Island contractors tackled some of the backlog of scrub bashing
including clearing vegetation from 3 of the scrapes.
Grove
Ditch / Colebrook Cut
As part of the overall
project CEMEX have funded the clearance of the ditch behind Grove Lake. This
had stopped functioning at all and was flooding the internal path and the
fields behind the reserve. As part of the process we have thinned the line
of alders along the back of Grove Lake. Two 15m sections of the ditch were
also widened to encourage marginal vegetation and these will be managed in
future years to control bramble and scrub encroachment.
3.
Surveys & Equipment
Small
Mammals
This is an area of the
ecology of the reserve that is little known and Dave Williams of Surrey
Wildlife Trust has carried out a survey of the reserve. His report is not
complete but early results indicate small populations of wood mouse, bank
vole, common shrew and pygmy shrew.
Water
Quality Testing Equipment
Moor Green is in a
fortunate position as Ken Crick has been surveying the quality of the water
for a number of years as part of his work on dragonfly and damselfly
populations on the reserve. A Lab Bench Photometer has been purchased which
will allow an improved analysis of water quality to be made including levels
of dissolved oxygen, phosphate and nitrate. This equipment will also be
available for use on other sites in the valley.
Butterflies of the Blackwater Valley
This is a companion guide
to the ‘Dragonflies of the Blackwater Valley’ that was produced two years
ago. It is hoped that it will encourage local people to get out and explore
the countryside of the Blackwater Valley and to use and value their local
greenspace. It is written by Peter Martin, an expert on butterflies of the
valley. The book is now available from BVCP for £3 including P&P.
ACCESS
4.
Footpath and Fencing
Footpath
The biggest
single element of the grant work is the re-surfacing of 400m of footpath
from Colebrook Hide to the bridge over the River Blackwater. The path has
been resurfaced at a higher level and with a camber and it is hoped that
this will provide a dry, firm surface throughout the year. The path on
either side of the river bridge has been raised so that there is no longer a
significant step up onto the bridge.
Fencing
The grant has
renovated the fencing around the whole reserve, hopefully giving it another
lease of life - keeping the cattle in and the dogs out. This has included:
-
The fence
around the western and southern boundary of the site has been checked and
wherever necessary scrub has been cleared off the fence, straining posts
and intermediates have been replaced and the fence re-tensioned.
-
220m of new
fencing has been installed at the back of Colebrook Lake to replace
existing dilapidated fence.
-
A new field
gate installed at main site access point.
-
100m of
replacement fencing between the footpath and bridleway adjacent to the
river.
5.
Access Points
Car Park
There has
been an on-going problem with motorbikes using the paths of the reserve and
this grant has provided the opportunity to address the problem. The existing
motorbike barrier has been replaced with one which motorised wheelchairs are
able to get through. At the same time a ‘horse stile’ has been installed
across the bridleway. This is essentially 2 sleepers on end that horses and
bikes can step over but motor bikes cannot.
South of
River Blackwater
A similar
system has been installed just south of the bridge over the River Blackwater
- which we believe is the main access route for motor bikes onto the site.
In
conclusion
This grant
has given us a great opportunity to make some real progress on the reserve -
and achieve some things from our ‘wish list’ that would not otherwise have
been possible. Some of the jobs are one-offs that hopefully will need little
or no attention in the near future. With the habitat work such as the
scrapes and ditches their progress will be monitored and it is hoped that it
will be possible to maintain them in good condition with volunteers or by
occasional use of contractors.

CHAPTER
3
REPORT ON BIRDS 2004
Recorder:
Ian Brown
During the
year 132 species were recorded of which 65 were present in suitable
breeding habitat in the summer, including one new breeding species. One new
species was added to the site list, Slavonian Grebe, bringing the total
number of species recorded to 204.
In the early
winter period there was a site record count of 279 Gadwall on Jan.17th. This
continues resurgence in numbers over the last few winters. Other duck
numbers were as expected, although Wigeon were down a little with a peak
count of 395. Up to three Little Egret visited the site in early January,
representing the first multiple occurrence. Goosander again used the site
regularly for roosting, although daytime numbers were slightly down.
Egyptian Geese were on eggs during February, making them amongst the
earliest breeders and the first such record for the site. Two Red Breasted
Mergansers were also noteworthy, being the first record for some years.
Spring was
heralded by a relatively early Willow Warbler on March 22nd, when Buzzards
began to put in more regular appearances. The first evidence of wader
passage was a March Oystercatcher and this was to begin a good spring for
the species. Highlight of the month was several sightings of Caspian Gull, a
newly recognised race of Herring Gull from the East. The month closed with
another record of two Red Breasted Merganser. During April there was a good
wader passage with plenty of variety including Jack Snipe, 5 Whimbrel, and
Bar Tailed Godwit, the first on the deck for many years! Other notable April
records included Little Gull and a singing Grasshopper Warbler. May was even
better for quality with a fine summer plumage Spotted Redshank, more Little
Gulls, a Nightjar and Osprey.
Generally for
most species it was a successful breeding season. Little Ringed Plovers
again bred successfully on and off the reserve while a pair of Redshank
valiantly raised one young despite consistent harassment from predators.
Lapwing were also moderately successful for the second successive year. The
reserve was again dominated by the expanding gull colony that increased in
size from 8 pairs last year to approximately 80! Nevertheless the Common
Terns continued to thrive, rearing at least 23 young. Mandarin continued to
do well in nestboxes and natural holes. Gadwall bred successfully for the
third year and Tufted Duck did moderately well, rearing four broods.
Barnacle Geese bred on the reserve, and Kingfisher and Grey Wagtail were
successful in their traditional sites on the river. Buzzard and Hobby were
seen regularly on the site during the summer and both probably bred nearby.
In June there was a Red Kite and a few records of Little Egret, the first
ever summer records.
In late
summer/autumn the highlight was probably an obliging Wood Sandpiper that
stayed for nine days, invariably in the Colebrook scrape. Other waders
included a brief staying Ruff, Greenshank and Ringed Plover. September’s
highlight was undoubtedly four records of Osprey involving at least two
birds, including the first multiple occurrence, and a record count of 34
Egyptian Geese. Autumn closed with an excellent record of Sandwich Tern that
sadly only lingered for 15 minutes in October. The year closed with some
notable December records including an unseasonal Black Tailed Godwit, seven
Pintail and two Brent Geese, but pride of place goes to the first site
record of Slavonian Grebe that largely gave obliging views on CLS but did
leave on a Friday night!
Last but
not least many thanks to the growing band of observers who submit records
including those who provide observers names on the log sheet.

CHAPTER 4
BOTANICAL SURVEY 2004
Dr
Delphine Hoyle
A
quantitative survey of the meadows on the North and West sides of Colebrook
Lake North was undertaken using a method based on National Vegetational
Classification Methodology. This method has been used since 1997.
Ten random
samples (1 x 1 m) were surveyed on 16th July 2004, five on the North side
and five on the West side of the Lake.
In each of
the sample squares the species present were identified and quantified on the
abundance present –
| 1. |
<4 % few
individuals |
6. |
26-33 % |
| 2. |
<4 %

4-10% |
9. |
76-90% |
| 5. |
11-25% |
10. |
91-100% |
In addition the frequency of occurrence was
also recorded -
|
I |
1-20 % |
(1 in 5
samples) |
|
II |
21-40% |
(2 in 5
samples) |
|
III |
41-60% |
(3 in 5
samples) |
|
IV |
61-80% |
(4 in 5
samples) |
|
V |
81-100% |
(5 in 5
samples) |
Table A gives
the frequency and abundance of the species found in the samples squares
while Table B lists other species noted in the immediately surrounding
areas.
As in
previous surveys black knapweed, ox-eye daisy and ribwort plantain were
abundant and there were increased amounts of bird’s-foot trefoil, common
mouse ear and lesser stitchwort. On the North side there was more wild
carrot and more selfheal on the West side. Several new species were recorded
including scarlet pimpernel, eyebright and goatsbeard. Eyebright was an
unexpected find. Goatsbeard had been seen adjacent to the path in 2003 and
was found in one plot this year.
Among the
grasses Agrostis continued to be abundant and there was an increase in
ryegrass.
Again there
was little evidence of tree or shrub invasion in the sample areas although
bramble continues to increase in the surrounding areas.
Seventeen of
the 23 species in the original seed mix were found in the sample squares and
two more in the surrounding area.
The number of
species found in the survey of the meadow areas of Colebrook Lake North has
remained fairly consistent over the past eight years with the exception of
2003.

The reduction
in 2003 was probably due, as reported in the 2003 Annual Report, to the
season and the abundance of rank growth which made some species difficult to
find and identify. Up to now the survey has been postponed until the bird
nesting season was largely over to avoid bird disturbance. This makes it
more difficult to identify those species whose flowering is over,
particularly if the grasses are flourishing. It is, therefore, proposed to
survey earlier next year.
Thanks are
due to Irene Draper, Doreen Dye, Lettice Tanner and Marjorie Trendall for
their help with this survey.

REPORT ON BUTTERFLIES FOR 2004
Recorder
Sue Proudley
The first
butterfly records for 2004 were 5 Brimstone, 2 Small Tortoiseshell, 2
Comma and 1 Peacock recorded on 16th March.
Brimstones
showed well in April, but numbers dropped in May and June. The Large White
and Small White numbers improved on the 2003 records but Green-veined Whites
remained about the same. Orange-tips were disappointing with numbers
dropping sharply in May. Skipper records were low again with Large Skippers
very low. Speckled Wood butterflies did well again this year with 35
recorded in August and 30 in September. Gatekeeper, Meadow Brown and Ringlet
numbers were better than in 2003.
A single
Green Hairstreak was recorded in April and 2 Purple Hairstreaks in July and
1 in August. 10 Small Coppers were recorded in August and Holly Blues were
also slightly up, but the only record for Common Blue butterflies was 4 seen
in August. Small Tortoiseshells and Peacocks were seen most months
throughout the summer. Red Admirals were not recorded until June, but were
seen in low numbers until October.
2 Painted
Ladies visited in June and were recorded again in July. 1 Painted Lady was
seen in August. There were no sightings of Clouded Yellows.
One Marbled
White was found by Dr Delphine Hoyle, while carrying out her Botanical
Survey, on 16th July. The Marbled White butterfly lives in colonies in tall,
unimproved grassland especially on chalk and limestone, downland, cliffs and
undercliffs.
The last
butterflies recorded were 3 Speckled Woods, 1 Red Admiral and 1 Comma on 7th
October.

REPORT
ON DRAGONFLIES AND DAMSELFLIES FOR 2004
Ken
Crick
It was the
18th May before significant numbers of damselflies appeared over the
reserve and shortly after on the 24th May the first Dragonfly was found on
the wing. The year’s survey embodied nineteen site visits of which thirteen
have records showing high levels of cloud cover.
The survey
recorded 17 species on the wing; those that had a particularly good season
were Migrant Hawker, Downy Emerald, Four-spotted Chaser and Azure Damselfly.
The Common Blue Damselfly, Common Darter and Black-tailed Skimmer all showed
positive signs of population recovery after some poor years.
On the
negative side Banded Demoiselle and Brown Hawker declined in numbers, with
the Large Red Damselfly almost vanishing from the site.
Members’
records submitted via the hide charts picked up only seven species. Two of
these were not found on the population survey, i.e. Beautiful Demoiselle
Calopteryx virgo, and Emerald Damselfly Lestes
sponsa.
My thanks go
to those members providing information who were:
J Warren
E Godden S Proudley C Rose
R Eagling NRG
I H Brown.
ODONATA
CHECKLIST
DAMSELFLIES Zygoptera
BLUE-TAILED DAMSELFLY Ischnura elegans
The overall
population figures for this species have stabilized over the last three
years - at a level 1/3 of that pre 2002. No exuvia were found. The first
sighting on the wing was on the 18th May when twelve individuals were
observed. Numbers peaked at 97 during the first week in June. At no time
were females seen ovipositing. The last sighting was on the 8th September
when a single male was seen.
BANDED
DEMOISELLE Caloperyx splendens
Larvae for
this species were again easily found in the River Blackwater adjacent to the
reserve. The population peaked at 272 on the 24th May; the last individual
was seen on the 21st September. Population levels held up well early in the
season but there was a significant reduction in numbers on the wing from the
last week in June onwards. This coincides with the period of dense leaf
cover over the river and adjacent habitats. For the bond between a dragonfly
and its place of emergence to be maintained the presence of factors other
than the correct water conditions must also be favourable. The correct
conditions on land for nocturnal roosting, feeding, mate-seeking and pairing
must also exist. It is felt that the increased riverside shading is starting
to degrade this habitat.
BEAUTIFUL
DEMOISELLE Calopteryx Virgo
J Warren
reported two females on the 24th July just to the west of the reserve
adjacent to a small stony bottomed stream entering the river from the south.
C Andrews and Y Hammond confirmed the sighting. The site was visited from
the 24th July every week until the end of the flight season but
failed to locate a single Beautiful Demoiselle.
LARGE RED
DAMSELFLY Pyrrhosorna nymphala
With the
damming of Colebrook Cut the demise of this species on site is almost
complete. Examples were seen on only five occasions and never broke into
double figures. By the 7th June the population was reduced to one male.
Fortunately this is a common species elsewhere throughout the valley.
EMERALD
DAMSELFLY Lestes sponsa
This species
did not put in an appearance this year. However, the hide chart records a
sighting by J Warren of a single specimen on the 24th August.
COMMON
BLUE DAMSELFLY Enallagama cyathigerum
Exuviae
proved numerous and easy to find along the 100 meters of shoreline that was
searched. One hundred and thirty nine were recovered between May and the end
of July. They are easily sexed and there proved to be slightly more females
than males despite the fact that the majority seen on the wing are males.
The adults first appeared on the wing during mid May. The population peak of
over 600 individuals lasted from 3rd June until the 21st June after which
numbers declined rapidly, with the final sighting on the 26th
September. This management plan key indicator species seems to have
stabilized its population levels over the last three years at a figure some
68% below its best years of 1999 and 2000.
AZURE
DAMSELFLY Coenagrion puellao
A small
number of exuviae were found. The overall numbers remain at a low level, but
unlike the common blue damselfly, which appears everywhere on site, the
Azure is most easily located at the water’s edge. It was on the wing from
2nd May until the 7th June when its recorded population peaked
at 30 individuals. Copulating and ovipositing was observed on three site
visits.
RED-EYED
DAMSELFLY Erythromma najas.
Exuviae were
first found on the 18th May and continued to appear periodically until the
27th July. The adult population peaked at 50 on the 25th May. The last
adult, a male, was also seen on the 27th July.
DRAGONFLIES Anisoptera
FOUR-SPOTTED CHASER Libellula quadrimaculata
The first
sighting was of a female ovipositing on the 24th May. The season proved
short with numbers in double figures for the first two weeks in June after
which there were no further sightings.
DOWNY
EMERALD Cordulia aenea
The north
west corner of the reserve cannot be described as woodland and it does not
have overhanging trees and shrubs, yet despite this lack of habitat
prerequisites, this is the fifth year in succession that the species has
been observed over this stretch of water. No exuvia were found this year,
but the number of adults on the wing made this our best year to date.
BLACK-TAILED SKIMMER Orthetrum cancellatum
Three exuviae
were found on the 24th May, one with the dragonfly still emerging from it.
In all 19 exuviae were located between the last week in May and the 13th
July. The species was on the wing until the 4th August.
EMPEROR
DRAGONFLY Anax Imperator
A single male
appeared on the 24th May, one or two males were seen throughout June.
Nothing was seen then until the 27th July, when two males were observed.
There were no further sightings.
BROWN
HAWKER Aeshna grandis
The overall
figures for this species were again low matching our worst ever year of
2001. Activity associated with breeding was not observed. The first sighting
was on the 13th July with a final appearance on the 8th September.
GOLDEN-RINGED DRAGONFLY Cordulegaster boltonii
Two males
were again seen this year, one at the start of July and the other at the
beginning of August. Both were seen at the southwestern end of the reserve
near the wooden bridge over the River Blackwater.
BROAD-BODIED CHASER Libellula depressa
This
occasional visitor was seen once, a single male, on the 3rd June.
MIGRANT
HAWKER Aeshna mixta
This was one
of our best years for this species. Good numbers of males, females and
copulating pairs were observed, along with 15 exuviae removed from the
emergent vegetation on the shoreline of the north western bay of Colebrook
Lake North. Twelve exuviae were found at this location during a single
visit, eight females and four males.
SOUTHERN
HAWKER Aeshna cyanea
Numbers for
this species, though low in comparison with some other species, remain
stable. The first sighting was a female seen on the 21st August; the last
was of a copulating pair seen on the 13th September, when an
ovipositing female was also observed.
RUDDY
DARTER Sympetrum sanguineum
First seen on
the wing on the 27th July, a single exuvia was found on the 4th
August. The last sighting was on the 13th September, with the highest total
on any given day being two.
COMMON
DARTER Sympetrum striolatum
The
population on the wing almost doubled compared with last year. The overall
figures are still well down on those consistently recorded in the late
1990s. Eighty-five exuviae were removed from the north western bay of
Colebrook Lake North. The first sighting was on the 21st June, with a final
sighting on the 14th November, during a work party when it settled on one of
the vertically cut faces prepared for mining bees.

REPTILE
REPORT FOR 2004
Peter
Scott
Reptile
recording on site has two components:
a) five
sheets within 50 metres of the hibernaculum near Colebrook Lake
North;
b) five
sheets spread along a 200-metre section of the north shore of Grove Lake;
Regular inspections
Fifteen
sheet-inspection visits were made between early April and late September.
All ten tins were checked each time. As in previous years, early visits
found no reptiles, but from May onwards most visits resulted in at least one
sighting. For the first time, not all the animals found were Grass snakes
(Natrix natrix), 3 Adders ( Vipera berus) giving some variety.
Most were under or close to the tins near the hibernaculum, though the tins
beside Grove Lake seemed to be used more than in previous years.
The overall
results are summarised in the following table:

The data
suggests a small increase in snake numbers, due to the addition of Adders to
the counts (the frequency of Grass-snake sightings remaining the same as in
2003). As usual, the small scale of the survey must be borne in mind when
interpreting these results. Perhaps the safest conclusion is that, at the
very least, numbers are being maintained.
Casual reports
Ten reptiles
were reported, down from 16 in 2003. Seven of these (5 Adders and two
Grass snakes) were seen on a single day in April by D. Courtenay. The
remainder comprised one report each for Grass snake, Adder and Slow worm.
[In addition, N. Silver reported seeing a Terrapin on the Hampshire side of
the river - near to, but not actually on, the reserve. Please keep your eyes
peeled: this is one reptile we don’t want!].
Summary
After three
years, a picture is beginning to emerge of fairly stable numbers of grass
snakes on the reserve. There are also signs of an increase in Adders, though
the very small numbers make this even less certain than the trend for Grass
snakes.
I am grateful
to those (D. Courtenay, N. Silver, B. Harland and K. Crick) who reported
seeing reptiles. Please take the trouble to note your sightings on the forms
in the hides.

REPORT
ON NEST BOXES 2004
Dr K B
Briggs
In January
2004 half of the small wooden nestboxes were replaced by woodcrete nestboxes
with the aim of reducing Great Spotted Woodpecker and weasel predation, as
well as reducing maintenance costs, Unfortunately, vandals preferred them as
target objects. One box had the so-called unbreakable front smashed and 2
Great Tit eggs were damaged. Another had the front removed causing a Blue
Tit to desert during laying. This box had the front replaced but the whole
box, complete with a clutch of 9 Blue Tit eggs was then stolen. These boxes
had been undisturbed by humans for 9 years when just plain wooden boxes. The
boxes have since been resited. The good news is that predation was reduced.
Forty-four nestboxes are now erected on the site and 38 were occupied in
2004.
Great Tit
Egg laying
started on 14th April and as very well synchronised with over 80%of birds
laying in the next week. The latest pair started on 1st May. The mean laying
date was 18th April s.d. 4.9 days for 16 pairs. Clutch size was large with
14 successful pairs laying 133 eggs (mean clutch size 9.5 s.d 1.0)
and 123 hatched (mean brood size 8.78 s.d. 1.42) and 122 fledged (mean
fledged brood size 8.71 s.d. 1.44). These are very good results and even if
the 2 pairs that suffered desertion and vandalism are added into the totals,
the mean fledging success is still 7.6 (s.d.3.3).
Blue Tit
Only 9
nesting attempts were followed, as the Blue Tit population still prefers
woodcrete bat boxes to nestboxes. The first clutch was initiated on 8th
April and 7 more were started by 24th April (mean 16th April; s.d. 4.6
days), but a re-lay on 9th May puts the mean laying date for all pairs back
to 19th April;(s.d. 8.6 days) In nine breeding attempts, 79 eggs were
produced (mean clutch size 8.7 s.d. 3.7). Two pairs deserted and one was
vandalised so only 49 young hatched from 6 successful nests (mean brood
7.5 s.d. 2.8 young). From this 44 fledged (mean fledging size 7.3 s.d.
2.8). From the nesting attempts the mean brood size at fledging was 4.8(s.d.
4.3) per pair.
Stock Dove
These birds
suffered greatly this year from Grey Squirrels and Mandarins that usurped
their nestboxes. Four pairs attempted to breed with the first clutches being
initiated on 21st March (s.d. 2.9 days). All the 8 eggs failed. The second
laying attempt was initiated in early to mid-April (mean date 11th April
+/- 6 days) and from 8 eggs only 3 hatched and just 1 young fledged. A
third attempt by 3 pairs in mid-May (12th May s.d.1.0 days) produced two
fledged young and a final attempt (fourth), laying on 26th June fledged two
young. Of the 11 nesting attempts followed, 22 eggs produced 7 young and
fledged only 5 birds.
Mandarin
Egg dumping
(2 or more females laying in the same nest) regularly occurs in hole-nesting
ducks and is often thought to be due to a limiting supply of nest sites. The
number of Mandarin boxes was increased in winter to reduce the effect.
Unfortunately it only provided more drey sites for Grey Squirrels and
aggravation for these ducks. The first five nests found started laying on
27th March (mean date 6th April s.d. 11 days) but only 2 nestboxes held
normal clutches of 12 and 14. Over the next two weeks three other nestboxes
held clutches of 19, 33 and 33, obviously the work of at least 7 females.
This put the probable breeding population at 9 pairs. Unfortunately, all the
first five clutches laid failed due to squirrels usurping the box during
egg-laying or aggression between female Mandarins. Sometimes the Mandarins
deserted as a Stock Dove built a nest and laid on top of the clutch only to
be covered by a Squirrel drey. In situations like this the boxes are cleaned
out to allow re-nesting. This was the situation this year and later in the
season successful nesting attempts were initiated in late April / early May
(mean laying date 7th May s.d 7 days). These five pairs produced normal, if
rather small, clutches and all hatched broods (mean clutch size 8.8 s.d.3.1
and mean brood size 7.6 s.d 3.2).
No Tawny Owls
or Little Owl used boxes this year.

APPENDIX A
PROFILE OF THE RESERVE
The Moor
Green Lakes Nature Reserve lies partly within the area administered by
Wokingham District Council and partly within the Borough of Bracknell
Forest. The River Blackwater, which forms the boundary between the counties
of Berkshire and Hampshire, runs close to the southern boundary of the
Reserve. To the north is Finchampstead Ridges, an area administered by the
National Trust. A map of the Reserve appears at
Appendix I.
The Reserve
covers an area of approximately 36 hectares (90 acres), the majority of
which lies within the flood plain of the River Blackwater. It contains three
lakes formed out of flooded gravel pits which are bordered by areas of
grassland, planted coppice and wildflower meadow. Two of the lakes,
Colebrook Lake North and Colebrook Lake South, are separated by an elongated
island through the centre of which runs the old water course of the
Colebrook Cut. The third lake, Grove Lake, lies immediately to the east
separated by a narrow strip of land. Within the lakes are several
gravel-capped islands and gravel beaches.
An important
feature of the Reserve is the presence of sluices, at the exit of the
Colebrook Cut and from Colebrook Lake into the River Blackwater, which allow
the level of the water in Colebrook Lakes North and South to be controlled
within certain limits. By this method, muddy margins can be exposed ahead of
the main spring and autumn passage of wading birds.
Overall
management of the Reserve is under the control of a Steering Group comprised
of representatives of CEMEX Ltd., Blackwater Valley Countryside Partnership
and the Moor Green Lakes Group. Practical day-to-day management and the
collection, recording, assessment and dissemination of information about the
Reserve is undertaken by the Moor Green Lakes Group, which was established
in 1993. The group committee members are listed in
Appendix G. The necessary
costs of the Group not covered by membership subscriptions are met by CEMEX.
Membership is open to all with an interest in the reserve, its wildlife and
its management,
Public access
to the Reserve is restricted to the viewing hides provided by CEMEX which
overlook respectively Colebrook Lake North and Grove Lake (see map at
Appendix I).
Unfortunately vandalism has meant that the hides cannot be left permanently
open, but members of the public may use the hides whenever they are in use
by members of the group (who have access at any time). The Colebrook Lake
hide incorporates a viewing window for observers in wheelchairs. When the
hides are locked, views over the scrapes adjacent to the hides can be
obtained from the screened viewing points alongside the hides. Views across
the Reserve can also be obtained from viewing points along the footpath,
which runs along the western and southern sides of the Reserve.
The main
access to the Reserve is from Lower Sandhurst Road where a car park has been
provided (Ordnance Survey grid reference SU805628). The shortest access to
the Grove Lake hide is from the Rambler’s Car Park at the entrance to the
Horseshoe Lake Water Sports Centre off Mill Lane (grid reference SU820620).

APPENDIX D
NOTES AND GUIDELINES ON BIRD RECORDING
Following the
creation of Moor Green Lakes (part of the Eversley Gravel Pit complex) as a
Nature Reserve, it was necessary to maintain a detailed log of birds using
the site in order to monitor bird populations. This influences conservation
management carried out on the site by the Moor Green Lakes Group and RMC.
These guidelines are designed to assist any persons visiting the site who
wish to submit their records. The collection of such data is an important
function of the Group, and all contributions no matter how small are
welcomed.
Recording
Area
The
boundaries of the site for recording purposes are defined as:
| |
a) |
South of the
Lower Sandhurst Road |
| |
b) |
West of Mill
Lane |
| |
c) |
East of
Longwater Road |
| |
d) |
North of the
golf course access track running from the Reading Road to Mill Lane. |
Information required
Ideally
records should be submitted on Eversley Gravel Pit recording forms available
from the recorder (please enclose an SAE). Records should be submitted every
3-4 months (or more frequently!) so that the log can be kept as up to date
as possible. Less frequent visitors may wish to submit their records
annually.
Where
possible the following information should be provided:
| |
1) |
Name of
species (include age/sex if known) |
| |
2) |
Number of
individuals (accurate counts particularly useful) |
| |
3) |
Date of
observation (and time if a fly over only sighting or short stay record) |
| |
4) |
Site location |
| |
5) |
Other
observations such as unusual behaviour or direction off flight of birds
flying over, etc. |
| |
6) |
Observer(s) initials. Records not submitted on forms should also include
name and address |
| |
7) |
Accompanying field notes if required. |
The species list for the site
at Appendix C includes a code number in the left hand column. This refers to
the type of records required for that species. The full details are:
| |
1*= |
All records
required. Please submit notes on the sighting with the record. These
notes should include details of the diagnostic identification features
which were observed at the time, other species nearby, the duration and
distance of the observation, weather conditions, optical aids used and
previous experience of the species. |
| |
1 = |
All records
required. |

APPENDIX E
NOTES AND GUIDELINES ON DRAGONFLY RECORDING
Any person visiting the
site who wishes to submit dragonfly/damselfly records may do so. Any
attributable records are gratefully received. Observers may add their
records to the monthly dragonfly posted in both Grove and Colebrook hides.
Alternatively records of a
more detailed nature may be submitted at any time direct to the recorder but
for preference before the end of October. If submitted after the end of
October the data will be logged on to the Reserve’s database but may be too
late for inclusion in the Annual Report.
Records can be presented
in any form that best suits the observer but should include:
|
Observer’s
name and address |
|
Date/Time/Weather |
|
Site
location, i.e.: |
| |

APPENDIX F
WATER
ANALYSIS 2004
For some
years now the pH of the reserve’s water bodies has been sampled. Water being
a major asset on the reserve, it was decided to add a limited amount of
chemical analysis to our on-site monitoring. The task is time-consuming so
was limited to four site visits per year. The pH measurements continued as
normal. Eight other water bodies within the valley from Farnham Park to
Bramshill Common were also sampled. The chemical constituents under
investigation were phosphate, nitrate and dissolved oxygen. From the data
collected it is clear that the reserve’s water matches the norm for
still-water bodies throughout the valley.
Phosphate
levels at Moor Green varied from 0 to 1.0 mg/I, nitrate levels from 0.1 to
0.7 mg/l and dissolved oxygen from 5 to 6 mg/I.
Samples were
also taken from the River Blackwater, which occasionally, at times of heavy
rainfall, flows into the reserve. For the river: phosphate levels varied
from 0.5 to 1.5 mg/l, nitrate levels from 4 to 10 mg/l and dissolved oxygen
from 5 to 6 mg/I.
The lakes
remained mildly acidic at all the measuring points from week 21 through to
week 38, as did the river.
The large
scrape in front of Grove Hide remains highly acidic. Measurements were taken
only twice, once at the beginning of the dragonfly flight season and again
at the end. A pH of 2.3 was typical.
