       Shropshire Ecological Data Network
Ecological data in Shropshire: Its collection, storage and use has been a complex
subject for many years but things may be getting clearer. This newsletter has been
produced to help those involved with biological recording keep up to date with recent
changes and progress and also pass on news of exciting new finds.

  The latest proposal by the Shropshire Biodiversity Partnership

More recently the idea of a „virtual Local Records Centre‟ or Shropshire Ecological Data
Network has been proposed. In practice this would still mean that records need to be
aggregated but the method of doing this may not follow standard practice.

Our aim is to help county recorders do what they do best. That is - manage and
      Newsletter 1. November 2008

validate their data. County recorders and other recording groups would ideally provide
updated datasets every year (or more frequently where possible) to a database
dedicated to storing just validated records. These records could then be used to best
effect by conservation organisations, planners, consultants and of course members of
recording groups. All existing un-validated records (such as many records on Wildlife
Site files) would be gradually passed to county experts for validation.

The difference with the standard model is that the most up-to-date and primary
databases are held by the recording groups and the centralised database is updated by
agreement with recording groups. All raw data should be passed to the recording
group for processing (often via SWT) – although, for recording groups with less
capacity, assistance can be provided for digitising records. Data for groups that do not
have local expertise will be passed to national schemes for validation.

The Shropshire Wildlife Trust has been establishing data exchange agreements with
many recording groups with the aim of establishing such a „clean‟ validated database.
A great deal of progress has been made with the majority of groups having signed up.
In return the Shropshire Ecological Data Network will arrange support for local groups
in the form of funding for atlas projects and even travel expenses for specific survey

We believe a biological records centre should do more than pass on records. Amongst
other things it should use the data to produce biodiversity opportunity maps used in
planning policy, it should identify gaps in the data and commission new survey work
(preferably by local experts), and it should support field recording, training and
publications by recording groups.

               The Natural Shropshire web site & maps
This web site is maintained by the Biodiversity Officers (Dan Wrench and Fran
Lancaster). It is used as a communication tool for the Shropshire Biodiversity
Partnership and some species recording groups.
The site provides:
    A list of all known „County Recorders‟ or key experts for species groups in
    A web page or link for many species groups
    Maps of known records for many species groups
    The Species Biodiversity Map. Listing all the species uploaded by the species

    A list of all Shropshire, and UK, BAP habitats and BAP species – with links to
      further information.
    Specific projects led by the Shropshire Biodiversity Partnership
    Reference documents and minutes relating to the partnership
    Events – A map of where many species recording groups are leading field

Species Maps are a quick reference for active species recorders and land managers.
For active recorders there is nothing like a blank area on a dot map to help get records
sent in. For land managers it can be extremely useful to know if, for example breeding
lapwing are known for the area. Not least because Land Agents, Ecological Consultants
and Natural England already use the maps to help inform options for environmental
stewardship schemes.

                          Tony Jacques -

Tony has recently started the new role of county recorder for moths and would, of
course, welcome any records. A new species for Shropshire found this year by Tony is
the micro-moth Phlyctaenia perlucidalis (1380). This species is nationally scarce and is
typically found further south and south east in the UK. The larvae are thought to feed
on various thistle species. The first records of this species in the UK were made at
Woodwalton fen in June 1951 to 1957. Further updates on this species will be added
when available.

Other interesting visitors to Tony‟s moth trap were 3 Feathered Thorn (Colotois
pennaria). This species is listed as common and widespread in Adrian Riley‟s “A
Natural History of the Butterflies and Moths of Shropshire” but other than Tony‟s recent
find there appears to only one current record. The low number of records may be due
to the late flight period of mid September to early December. Mercury vapour moth
traps used at this time of year would be likely to turn up more records for Feathered

Older records for moths have not yet been added to Natural Shropshire but earlier this
year the Shropshire Biodiversity Partnership provided funds to Adrian Riley to digitise
all the Lepidoptera records used in his book. Adrian was good enough to include a vast
number of additional records some of which are very recent. These records were
passed to Butterfly Conservation for processing and are now being added to records
held by Shropshire Wildlife Trust. We hope to present all these records on the Natural
Shropshire web site in the next few months.

                                    Cranefly Recording
                      Pete Boardman -
Following the publication of the Shropshire Cranefly Atlas recording has undergone a
bit of a lull. I am however still as proud as I was of the publication as when I first saw
it, as the first modern county account in Britain. The data has been passed to the
National Cranefly Recording Scheme for inclusion upon the NBN Gateway, and is also
to be found on the excellent Natural Shropshire website too.

Most specimens collected during 2008 (including a major set by Nigel Jones) have yet
to be identified, a job I generally set a side for the dark winter evenings, though as I
write this there are still plenty of craneflies around, the autumn Tipula species and the
odd Dicranomyia species are still active. Most obvious at the moment are the winter
gnats (Trichocera sp), familiar to many naturalists as groups of craneflies that gather
in sunny spots and dance together in competition for females over the autumn and
winter months, and several of the different species we have in Shropshire will continue
to do so until the spring craneflies arrive once more. One of the good aspects of
looking at craneflies is that there is always something to look at – even in the winter.

During 2009 I intend to get more recording done and will be targeting some of the
gaps that the atlas indicated, as well as searching for some of the rarities that recent
work by other dipterists have highlighted.
 I am always keen to see specimens collected by other recorders, and some species
                       can be identified from photographs.

The hoverflies, family Syrphidae, are relatively well studied in Shropshire. Nigel Jones
has made over 5,500 individual records of around 180 species, plus the NBN Gateway
presently holds 2,800 further records. Other naturalists have made numerous notes of
hoverflies encountered, but most of these records need to be collated for recording
schemes. Most celebrated amongst Shropshire‟s hoverflies is Chalcosyrphus eunotus, a
denizen of streams in ancient woods that has a strong association with the Welsh
Marches area. C. eunotus is a rarity across most of Europe and Shropshire appears to
be a real stronghold for this enigmatic fly. Amongst the showy species, the magnificent
hornet sized Volucella zonaria arrived in the county for the first time in 2006, with a
second sighting in Shropshire BAP officer, Dan Wrench‟s garden in Shrewsbury in 2008.

                      Malcolm Monie -
This year we the project has been looking at the boundaries of the water vole
population in the wider Whitchurch area. Survey activity has been mainly in the north-
east and the south-west directions. This has involved cross-border co-operation,
something which is likely to increase.

A survey day jointly with Wrexham and the Environment Agency Wales was held on
and around Fenns-Whixall Moss. This produced a number of previously unrecorded
populations on both sides of the border.

A day just north of Whitchurch, but in south Cheshire, was negative for water voles
although good habitat was found but also mink prints. We are now working with
Richard Gardner, North West Lowland Water Vole Project Officer with Cheshire WT, in
looking at south Cheshire and links to the Whitchurch population.

All the Water Vole data collected by the project since 2006 has now been fed into the
record systems held by Shropshire Wildlife Trust. Water voles on a farm between
Northwood and Whixall, 10.5 km from the centre of Whitchurch, are currently the most
distant colony for which we have survey evidence and habitat corridors to link them to
Whitchurch population.

                        Ian Thompson -

The expected Harlequins have not shown themselves, or not been recorded in high
numbers in Shropshire. There are a few records from Alveley Country Park and the only
record of them getting into houses in small numbers was from Ironbridge. This lends
some credence to the hypothesis that the most likely route from Worcestershire is via
the Severn valley since the South Shropshire hills and the Wyre are quite a barrier to
many species. We have also recorded the first larch ladybirds in Shropshire in 2008, this
is not a new species but has never been officially recorded before.

               What Can Be Achieved – The Upper Onny Case Study
                       Leo Smith -
The Upper Onny Wildlife Group was formed in 2003, and has carried out a Breeding Bird
Survey each year since 2004, concentrating on Curlew and Lapwing. It covers about 122
square kilometres, between the Long Mynd and the Welsh Border. Most of this area is
within the Shropshire Hills Area Of Outstanding Natural Beauty (AONB) and the
Shropshire Hills Environmentally Sensitive Area (ESA).

The area has been divided into 30 2x2 km squares and each member surveys a square
looking for the target species. If they are located, a semi-professional ornithologist
undertakes a follow-up survey, locating the birds and monitoring breeding success.
Farmers with the species nesting on their land are contacted, advised of their presence,
and encouraged to take appropriate conservation measures. Natural England HLS
advisers are actively involved. The most important farm for Lapwing has joined HLS,
which is funding management of cattle pasture for the birds‟ benefit, and another
important farm has extended a Countryside Stewardship Agreement to improve
management of arable land for Lapwing. Other farms have also taken conservation
measures. The Group has also developed a Programme Of Action, to promote the
conservation of Lapwing and Curlew, which has been implemented with the extensive
and valuable support of Partner organisations, including the AONB and Natural England.
This work appears to have helped arrest and reverse the decline of Lapwing in the area
– the population was 19 pairs in 2004, 18 in 2005 and down to only 13 in 2006, but it
then increased to 17 pairs in 2007 and 26 pairs in 2008.

Monitoring of Curlew by the Group over the same period suggests that 4 pairs have been
lost, a 10% reduction in population now down to around 35 pairs. A leaflet, Please
Conserve Our Curlews, providing advice on grassland management, has been produced
with the support and endorsement of Partner Organisations – AONB, NE, RSPB, National
Trust and FWAG.

A similar organisation, the Upper Clun Community Wildlife Group, was launched in 2007.
It is working closely with the local SWT Branch. It highlights the potential for involving
people with limited scientific expertise in active conservation work without the need to
make a big commitment of time, or doing physically demanding work. The Group found
20-22 pairs of Curlews in 2007, but only 14-17 in 2008

The members of the Ludlow branches of SWT and SOS, together with the Craven Arms
local RSPB Group, carried out a Lapwing survey in their area in 2007, reinforcing the
evidence of serious population decline in another part of the County.
The Upper Onny Wildlife Group has proved that local people, supported by professional
  workers, and with the help of Natural England, can reverse the decline of Lapwings.
Training for members of all these Groups, on finding and recording Lapwing, has been
 carried out with the support of the Field Studies Council Biodiversity Training Project.

                   Shropshire Botanical Society – Alex Lockton
The Society has 120 members and holds six field and two indoor meetings a year; it also
produces a newsletter twice a year, which non-members can read on the web site.

The Botanical Society has a database of 360,000 records of vascular plants in Shropshire
and adds 20,000 each year, as well as adding historical records. One current source of
these is William Hamilton's 1909 Flora of Shropshire, containing 2,100 pages of species
accounts that all need to be transcribed. Another is the Herbaria at Home project, which
digitizes herbarium collections at museums and universities. The Botanical Society, with
support from SEDN partners SWT, SCC and NE, has spent £10,000 photographing
herbaria with significant collections from Shropshire which is yielding valuable records.

Before joining the SEDN, the society provided data enquiries directly to consultants, but
now has an agreement with SWT to supply data in return for an annual fee. This is less
than used to be made from enquiries but means a smaller workload for volunteers. It
also means SWT has access to the definitive data for vascular plants in the county and
can provide a better level of service to enquirers, hopefully helping to promote nature
conservation. NE and SCC also get access to the database and all SEDN partners can
send records and, if necessary, specimens to the county recorder.

This is an efficient and effective model, but does mean that each group needs to be able
to operate a database which communicates with the other parts of the network and
needs to be willing to do so. It is easier to work on your own without the complications
of politics or money but if you can work with other people and want your own work to be
put to use, the SEDN is a unique opportunity. There is no other county where expert
volunteers are involved in the records centre in this way and the benefits work both
ways. By devolving the work to the societies, the funding organisations are taking a risk
but one that is already repaying them handsomely. We are already talking about vastly
more records than could conceivably be held by an LRC after just a year or two of
operation and all of them validated by experts. It will be interesting to see if it works. It
may create opportunities for naturalists to do much more than ever before.
  Visitors are welcome at meetings even if they are not members, but it is polite to ask
first (there's always a contact name on announcements).

Insect migration has been monitored annually since 2003 through specifically targeted
field meetings and members' reports. In 2008 we did not have a specific field meeting,
but members report that autumn 2008 was marked by a regular southward passage
through the county when the weather has been good. Large White and Red Admiral have
been the most numerous, with Small White and Migrant Hawker reasonably frequent.
Migration was noted from late August to the middle of October. Migration at Alveley also
included single examples of Hummingbird Hawk and a Darter sp.

In 2008 SIG undertook a moth-trapping programme at Attingham Park, as this
potentially rich locality has surprisingly been little trapped in the past. Early results
show a good diversity of broad-leaved woodland moths, though nothing dramatic as yet.

Plant galls and leaf mines are another ongoing project. A field meeting to Bury Ditches in
October found this to be an excellent site for plant galls and leaf mines. Our visit did not
turn up anything especially rare, but the variety and abundance, particularly on Oak,
was impressive.
