Forest Nightjars

Nightjar a

P1030016a

Twelve members and guests joined Andrew Bluett for a late evening meeting in search of the elusive and intriguing Nightjars in the Forest of Dean. A Roebuck was sighted in the edge of the football ground soon followed by a cock Pheasant and a Fallow Doe on the walk up the hill towards the open areas of clear fell. As the evening drew on the Willow Warblers and a Garden Warbler ceased singing, the evening chorus of Robin, Blackbirds and Song Thrush died down as the party headed towards the first location where a distant Nightjar was heard faintly churring some distance away. A second, closer bird was followed up and was churring strongly. Brief and careful use of a recording brought the bird closer so that it flew around and showed off its song and calls within a few yards of the observers. On the return by a different route a third bird was heard churring on another area of clear fell some distance to the north.

Woodcock put in only a brief and fleeting appearance – heard but not seen well and only two brief calls from Tawny Owl were somewhat disappointing. However, the party had seen and heard Nightjars so were quite satisfied with the evenings events.

Nightjar can be seen from early June through July and into early August or even later, they are distributed in suitable habitats across the Forest of Dean but only in small numbers compared with other counties to the south and east where better habitat is found on heathland and around forest edges. Being crepuscular birds, it is necessary to venture out in the late evening as darkness falls on still, warm and windless evenings to view them, a measure of luck is also required so that more than one visit may be needed for success even at sites where the birds are known to be present.

 

 

Cinderford Northern Quarter Hybrid Planning Application Ref. P0663/14/OUT

GNS has objected to the proposed development at the Cinderford Northern Quarter.

The full text of our objection follows, a copy of our objection is posted on the council’s planning portal web page. The whole application together with all documents received are available to view – copy and paste the following link into your browser’s address bar, or simply click on it to open it in another window:

http://publicaccess.fdean.gov.uk/online-applications/applicationDetails.do?activeTab=summary&keyVal=N4FS82HI01000

otherwise go to The Forest of Dean District Council web-site, choose Planning and “simple search”, use the word “Northern” as the key word and you will find the application starting with the words “A Hybrid planning application comprising demolition…”

Our Objection:

The Society’s Standpoint

The Society’s response to the above planning application begins with our stated position first published on the Society’s web-site on 1st December 2013 and subsequently in GNS News in March 2014. In essence, that is as follows:

“Having discussed all aspects of the Cinderford Northern Quarter (CNQ) Development and the Cinderford Regeneration Environmental Forum at the Executive Committee Meeting on 27th November 2013, the Executive Committee of the Gloucestershire Naturalists’ Society (GNS) has concluded that the Society’s standpoint and course of action should be as follows:-

The Society does not in any way support or condone the CNQ development as proposed and very much regrets the effect that the development is likely to have on the wildlife and habitats across and in the immediate vicinity of the development area.

The Society believes that whilst the investment and potential improvement for the economy and employment prospects is warranted and welcome in the Forest of Dean, especially in the current economic climate, the development as proposed is in the wrong location and would be far better sited elsewhere for a variety of reasons, not least the conservation of the species and habitats in the area.

The Society believes that, if protest against the Area Action Plan fails, and no engagement in the mitigation process takes place, any future planning applications within the Area Action Plan framework are likely to be approved with little or no change.

The Society believes the best means for influencing planning and development decisions will be via the Cinderford Regeneration Environmental Forum. For that reason, the Society will participate in the Forum and promote the interests of wildlife within that arena as best it can, alongside the representatives of Gloucestershire Wildlife Trust (GWT) and other organizations.

The Society notes the six identified “Purposes” within the remit of the Forum and will endeavour to ensure that these are properly applied in the interests of wildlife.”

Summary – The Society very much supports the regeneration and investment proposed for Cinderford and the wider Forest of Dean but absolutely believes that the siting of the investment on the Cinderford Northern Quarter area is wrong because of its impact on the environment, habitats and wildlife there and because of the separation of the development from those who should benefit from it.

The Society believes that the position of the proposed investment should be substantially closer to the population, existing infrastructure and facilities offered by Cinderford town, for the benefit of both those on the development site and for the town and its inhabitants and to more directly support the regeneration of the town and other facilities there.

The Development Proposal

The Society has had a limited time in which to peruse the documentation attached to the Hybrid Application which when first published on the Forest of Dean District Council’s web-site amounted to over 140 documents and had by 15th May 2014 been extended to well over 150 documents.

The documentation in itself is extensive and complex, there are many hundreds of pages and whilst some are reasonably easy to read and interpret, much of the language and layout of some documents is technical and requires much study in order to properly understand and digest them.

The Society believes the impact of the development will extend far beyond the confines of the site, both in terms of the natural environment and on the surrounding area and its population; we have doubts and concerns relating to many facets of the development and its effects, both during the construction phases and after occupation in the longer term; we have similar concerns relating to the existing flooding and geological issues under, on and around the site: we are particularly concerned that past mining on the site may render the proposed buildings dangerous or unstable, and that the cost of identifying ancient mineshafts and flooded galleries will make the project unsustainable. Many of the objections already submitted on this topic by qualified mining engineers to the Forest of Dean District Council are eloquent, notably the 2012 report submitted to the Forest of Dean Verderers, and the note by The Coal Authority, which surrounds its lack of objections by many serious pre-conditions. Because of the concerns we have, and given the uncertainties, the Society believes that it is inadvisable to proceed on a site with such complex and potentially dangerous issues inherent in it.

However, since we are a Naturalists’ Society, we have chosen to confine our primary concerns to the habitats and species that will be affected.

Ecology & Biodiversity

Turning then to the Society’s primary interest, that of the effects upon the habitats and wildlife in the area, we have significant concerns that the mitigation proposals outlined in Chapter 7 “Ecology & Biodiversity” do not match the aspirations of the Biodiversity Strategy for the area. We are also very much of the opinion that the extremely short time frame envisaged for carrying out the mitigation operations will be inadequate to allow the many and varied species of wildlife to adapt in time.

There is a constant repetition of the phrase “Based on the above mitigation, it is considered that potential impacts on (taxa) from phase XXX will be fully mitigated” and the overall impression is that the effects upon wildlife and habitats will be either neutral or slightly negative. This is not an adequate response to the disturbance and destruction that will result from the development of the site, given that much has been made of the intended “net increase” for wildlife and bio-diversity as a result of the development.

We believe that Chapter 7 seriously undervalues the wildlife and biodiversity and fails to understand and appreciate the interdependence that is intrinsic within an evolved ecosystem. CNQ is by definition a “brown-field” site; recent studies and publications, not least by the Gloucestershire Wildlife Trust, demonstrate clearly that so-called “brown-field sites” are often much richer in terms of diversity then “green-field sites”, where agricultural change has severely reduced, if not eliminated, biodiversity value; the site has regenerated and restored itself, over several decades since the cessation of industrial activities, into a complex and multi-faceted matrix of varied habitats used by a great number of resident, breeding and wintering species. Within this framework, many species interact with, and depend upon, each other and those above and below them in the food chain so that the ecology and biodiversity should be considered as a whole, and not as a list of those few protected species followed by little or no consideration for all else.

Birds:

This Society and others believe there is a serious undervaluation of the overall mix and interactivity of the list of species recorded on and around the site. Each species uses the site for one reason or another and the mix of species is a dynamic and changing entity through the seasons of the year. It is a breeding site for Tree Pipit, Willow Warbler, Chiffchaff and others that are all to some degree threatened both locally and across the UK.

There are already identified on and around the site a series of species that are of Conservation Concern in the UK because of their inclusion on the national Red (ten, according to the RSPB) or Amber (21, again according to the RSPB) Lists; this is an immediate and obvious reference to the status of these species and should warrant greater consideration of the effects that will be rendered upon them by the proposed development and its after effects. Species which have their Gloucestershire stronghold in the Forest of Dean, and are recorded in good numbers in and around Cinderford Northern Quarter, include the Hawfinch: according to the British Trust for Ornithology’s “Bird Atlas 2007-11”, published in 2013, the Forest of Dean, North Wales and the New Forest are the three remaining UK strongholds of this species; indeed the new “Birds of Gloucestershire” (published in 2013, and based in very intensive coverage of the county) chose Hawfinch as the cover species for the whole volume, to emphasize its iconic status in Gloucestershire. Other species of national concern with particularly strong populations in the Forest of Dean in general and Cinderford Northern Quarter in particular, are Goshawk and Willow Tit

Bats:

Much attention has been given to the Bats (particularly Lesser Horseshoe Bats) on the site, given the proximity of the European recognised SAC, for which CNQ forms as essential feeding and roosting area. It would appear that much of the mitigation is based on the confidence that arises from predictions that could easily and ultimately fail to be correct. Whilst the mitigation and accommodation measures that are proposed appear to deal with all concerns relating to the bat populations, we are not convinced by any means that these measure will work; in particular we are very doubtful that there will be time (given the very tight schedules for beginning construction work for the bats to adapt their behaviour to match the new environment and predicted outcomes. There is very great local expertise on this issue in the local Bat Group, and we urge the proponents of the scheme to take full account of the comments of local experts.

Other Mammals:

There are a number of measures offered for dealing with mammals on the site, but the numbers are low and the list of species is limited. Whilst we believe the mammals are the taxon least likely to be impacted by the development, there is no doubt that some will and the introduction of roads on the site will inevitably lead to casualties.

We also have concerns that the development of the college and hotel facilities and of the residential area will lead to the increase of rats and domestic animals that will significantly impact on the wildlife in the medium to long term. Whilst figures are uncertain and emotive, there is no doubt that the introduction of alien species to a site that is currently little troubled by them, will increase the predation, disturbance and mortality suffered by wildlife. There is even the potential to introduce some feral individuals that would be absolutely unwelcome.

Amphibians and Reptiles:

These taxa are those that will be most directly and significantly affected by the construction phases and by the overall loss of scarce and irreplaceable habitats. CNQ is a prime location in the county for all three species of newt, not only for the European Great Crested Newt, but also for Palmate Newt and Smooth Newt. It is a prime site for Adders, which have a substantial home range and need connectivity between populations to maintain genetic diversity. Adders are in severe decline at national level, because of habitat loss. We are aware that there have already been casualties during the site investigation works and it is acknowledged by all that further casualties will arise as time goes on. We are not at all convinced that the proposals for collection and translocation will be effective, the more so as the time schedule is very tight, and foresee the loss of these species on a grand and unacceptable scale.

Invertebrates:

The Ecology and Biodiversity documentation chooses to treat all invertebrates as a single group. This is quite astonishing given the diversity and volume of invertebrates on and around the site. Invertebrates make up the vast majority of the animal kingdom and each type or group has vastly different needs, habits, habitats, lifestyles, purposes, causes and effects within the ecosystem.

To consider one group in particular, the Odonata (Dragonflies and Damselflies) on and around this site are particularly special in the context of the Forest, the county and the country; 29 of the 32 Gloucestershire species of Odonata have been recorded in the 10k square that surrounds the CNQ site; several of them are the most threatened and scarce of their type.

Similarly, the Lepidoptera on this site include several threatened, scarce and remarkable species that require proper consideration in order to preserve them and their habitats. The submission by Butterfly Conservation notes that, among other Lepidoptera, declining butterflies such as Wood White and Dingy Skipper and the rare Forester Moth were recorded on the site in 2013, while Grizzled Skipper was previously recorded there. Two other rare butterflies, the Small Pearl-bordered and Pearl-bordered Fritillary are both present.

Much effort and resource is being expended in the Forest, the county and other parts of the country to preserve and keep some of these species from the brink of extinction. It is a matter of much regret that on this site, they could be lost without having been properly considered or accommodated.

The Society believes that each of the major groups of invertebrates at the very least should warrant consideration in its own right and separately from the others with due regard given to accommodating and preserving them and their specific habitats. Furthermore, they should be considered in the context of their relationship with the other, higher species that interact with and depend upon them.

Botanical and other taxa:

The changes to the landscape will undoubtedly affect the plants, fungi and other taxa that do exist there. Apart from the physical damage caused by the construction, there will inevitably be a rise in the pollution levels over time with heavy elements and gases settling in the bottom of what is effectively a closed valley. There is no proposed mitigation for these effects; the botanical world has significantly undervalued in the Ecology and Biodiversity documentation.

Mitigation:

Aside from our reservations in respect of the mitigation in general, we as a Society are convinced that some of the mitigation measures proposed to have positive effects for some species will surely have very negative effects upon the species already in the areas to be changed and “improved”. Habitats are like energy, they cannot be created, they can only be changed from their existing state so that there can only be a negative impact on those species adapted to deal with and live in any given existing habitat by altering it to suit another species. No species, despite its status and threat level (and the associated protection that goes with that) should be considered more important than another. Each species has its place within the ecosystem and should wherever possible be allowed to remain and thrive in that position; it should not be sacrificed for something that is perceived or purported to be more important

Humanity:

Whilst the Society has recognised and voiced its support for the regeneration of Cinderford and the wider Forest for the good of the population, the increased presence of humans on the CNQ site during and after construction and occupation will have negative effects on the surrounding area. The CNQ site, whilst used for recreation by the local population has in fact been relatively undisturbed by human presence and effects in its current state and for some time. It has been relatively remote and much of the human use of the site in recent times has been for simple and quiet enjoyment. This will change, by the introduction of the residents and their offspring and pets, the student population at the college and the employees in the industrial zones. This will ultimately lead to the degradation of the areas immediately adjacent to the proposed developments and the surrounding area. Whilst the population should be able to access and enjoy the natural world and environment, their very presence has unintended consequences and effects.

Conclusion:

Given the above comments, The Gloucestershire Naturalists’ Society finds itself in the position of having to object to the proposed Cinderford Northern Quarter development. We are firmly of the view as we have stated before and above, that whilst we very much support regeneration and the reintroduction of employment and some measure of prosperity to Cinderford and the wider Forest, we cannot support the development of this site to the detriment of the habitats and wildlife that currently exists upon it.

At this time we have little confidence in much of the proposed mitigation, nor in the very short time allocated for it, and do not see any significant evidence for the suggested positive outcomes for wildlife and the environment.

We believe that the proposals thus far are a grudging response to the Ecological and Biodiversity requirements imposed by law that should have been foreseen and adequately dealt with at a much earlier stage in the planning of the development, with significantly more consideration given to the ecosystem as a whole, rather than simply concentrating on the few protected species that exist on the site.

Cinderford Northern Quarter 17th May 2014

Andrew Bluett was joined by Nick Christian and Rob Husbands for a morning’s exploration of the CNQ site at this time when much of the breeding process is in action for birds and most other species. My thanks to those unable to accompany us who sent their apologies, this is a busy time for most naturalists and many had other commitments.

The morning was very hot and sunny but equally, very productive. We first visited and inspected the areas that have been stripped as part of the current site investigation works. Many areas where this exploration is to occur have had the majority of the grass mat and other growth removed almost to bare earth in places, including the removal of small trees and some shrub growth.

The first find was a very lively and active Slow Worm on one of the stripped patches; later, a fully grown Adder quite literally crossed our path. On checking other areas of the grassland a second and less active Slow Worm came to light as did a large, probably male Grass Snake and a very small, brown and juvenile Adder.

Ground nesting birds were represented by at least six Willow Warblers singing and one female off a nest, two Chiff Chaffs (most would now be almost silent having active nests), at least one Pheasant calling and a solitary Tree Pipit. The Tree Pipit was in a different location from the previously recorded birds on the site, it is possible that this was a third bird in a new location, though it could have been one of the singing birds noted last week, having been disturbed and displaced by the investigation works. Later visits when there are young in nests may shed more light on this situation.

Other birds noted – Hawfinch, Whitethroat (3), Goldfinches (20), Wood Pigeon, Garden Warbler (5), Carrion Crow (resident pair), Green Woodpecker, Great Tit, Long Tailed Tit (family party), Robin (fledged young), Blackcap, Wren, Blackbird (nest with eggs), House Sparrows and a number of Swallows hawking for insects.

A few damselflies and early Dragonflies (Common Darter and very bright yellow Broad Bodied Chaser) were in evidence. Butterflies were represented by Small Heath, Orange Tip, Common Blues, Green Veined White, Dingy Skipper, Grizzled Skipper, Small Tortoiseshell and Speckled Wood.

“Floodplain Meadows and Society: A Two-Way Relationship”

About 100 people were at this two-day national conference (held in the Gloucestershire section of the Cotswold Water Park), including academics, community groups, statutory agencies, and wildlife organisations. GNS sponsored and was represented by Mike Smart and Juliet Bailey who have a long-standing interest in the flood meadows of the Severn Hams. We were taken to jewel sites just in Wiltshire– North Meadow at Cricklade and Clattinger Farm near Somerford Keynes, too late to see the Fritillaries in flower, though the orchids at Clattinger were knock-out. Back at base there were nine talks on the themes “Ecosystem Services of floodplain meadows” (meaning what floodplains can do for us), and the reverse – “What we can do for floodplains”. All this was interspersed with copious good food and chat with names put to faces, new links forged, and individual in-depth discussion. The Floodplain Meadows Partnership who organised the event, has a well-illustrated website with all sorts of useful information on the wildlife, history and management of these rare and amazing places. See http://www.floodplainmeadows.org.uk/

Additional thoughts from a non-botanist:

Having spent many years looking at the birds of hay meadows along the Severn and Avon, I have gradually come to realise the importance of understanding the botany (and also the soils) of floodplain meadows. These floodplain sites on the Cotswold dipslope are so different from the meadows in the Severn and Avon: I would hardly have recognised Clattinger Farm as a flood meadow, so different (and drier!) is it from sites like the Great Hay Meadow at Twyning, or the meadows along the River Chelt. For years we have been arguing on how the Gloucestershire flood meadows fit into the National Vegetation Classification (NVC), developed by Prof John Rodwell; and there was the great man in the flesh, presenting a fascinating lecture, not on the botanical intricacies of these meadows, but on their history, beauty and aesthetic value, with quotes from Henry V to show that Shakespeare too knew perfectly well what a flood meadow was. And in addition, other experts explained that Mesotrophic Grasslands of the MG4 category are now split into four different subgroups, of which North Meadow is the driest with the widest floral richness, while those in the Severn are in the wettest subgroup, less rich botanically, but no less interesting. A really rewarding session!

Cinderford Northern Quarter – Site Investigation Works

Andrew Bluett and Mike Smart attended a briefing organised by Homes and Communities Agency and the Forest of Dean District Council at the council offices in Coleford on Friday 9th May regarding further site investigation works to be carried out at the CNQ site over the next few weeks.

 

The geophysical engineering contractor and professional ecologists lined up, under the watchful eye of the promoter, Homes and Communities Agency, to give the presentation which illustrated and described archaeological and geophysical investigation works to be carried out.

 

The archaeological works are intended to locate and seek more detail on former industrial remains including tramways and the like in various areas;

 

The geophysical investigations are aimed at locating a high pressure gas main that crosses the site, the route and details of which are apparently completely unknown, the detail of the limits, depths etc. of the opencast excavations and any other physical difficulties under the proposed development areas. The means of carrying out the geophysical investigation will include the use of 4 – 6 “low impact” drilling rigs and a variety of testing methods on a number of pre-determined lines, primarily across the site around the lake and between it and the Newtown/Steam Mills settlement areas to discover the characteristics of the ground below.

 

The works are to be carried out under a “European Protected Species” licence granted last week because of the known presence of the European-protected Great Crested Newt, and will commence on Monday 12th May, lasting for approximately 6 weeks.

 

Ahead of any work to be carried out we were assured that ecologists (from TACP, Cardiff – “Our Vision is the Future”) going ahead of the machines on hands and knees would carry out a “fingertip search”. There will be resident ecologists on site throughout the duration of the works who will monitor all species that may be affected, specifically the Great Crested Newts, reptiles and ground nesting birds. Species not specially protected like the Great Crested Newt would be subject to RAMs (Reasonable Avoidance Measures) which it was suggested would include 10 metre exclusion zones.

 

We were also advised that excavations would not in any single case last for more than a full working day, that spot boards and traffic mats would be placed to protect the ground and species under the working areas, that all spoil would be reinstated in the reverse order from which it is extracted and that there would be a full “audit trail” of documentation covering the ecological management protocol.

 

It was stated that ecological and archaeological information would be made public via the planning portal on the FoDDC web-site.

 

It is regrettable that this work is to be carried out at this time of year, in the midst of the breeding and reproductive season for most of the species inhabiting the site. Andrew Bluett advised the meeting that there were ground nesting Tree Pipits in the work area last year and that it was likely to be so this spring. On Sunday 11th May a discussion with Rob Husbands and a site visit confirmed that there were at least two Tree Pipit nests on the site in 2013 and that two singing males are currently present along with at least two Chiff Chaffs and five Willow Warblers. We are of course also fully aware of the habitation by the various reptiles, amphibians and invertebrates across the area.

 

Andrew Bluett has postponed the next proposed GNS site visit to the 17th May so that any effects of the first weeks-worth of this work might be observed.

 

GNS will be considering the issues of the proposed land swap and the hybrid planning application over the next few days and in consultation with GWT will decide what comments we will make on both of these issues. We have received some information and comment already from specialists and will take these thoughts into account before making our own comments.

Field Meeting – Woorgreens Lake & Crabtree Hill – 19 April 2014

Andrew Bluett was joined by Juliet Bailey, Ingrid & Colin Twissell, Des Marshall, Tiz Butler, Rob Curtis, Daphne Lane and Trish Bluett together with seven guests from Painswick Bird Club for a field meeting of general interest at Woorgreens Lake and Crabtree Hill in the Forest of Dean.

The day started bright but by 11.00am had clouded over and whilst it remained bright it was decidedly chilly with an easterly wind predominating. By the end of the visit conditions had improved somewhat and were reasonably warm in the sunshine but still required the wearing of fleeces!

The walk commenced from the start point near Kensley Lodge, led towards Woorgreens Lake and around the south and east sides of the lake, then to the Forestry road along the south side of Crabtree Hill. Taking the main track we visited the heathland on the top of the ridge to view the landscape then returned to Kensley Lodge and the “Cathedral Window” before going back to the start point.

The cold ambient temperature meant few insects and no reptiles other than a decomposing Toad or Frog in one of the drainage ditches but birdlife was plentiful. Nuthatch and Blue & Great Tits were close to the car park in the Oak woodland and on the lake were Canada and Greylag Geese, Mallard, Tufted Duck, Mandarin, Little Grebe, Lesser Black Backed Gulls, Heron, Coot and Moorhen. A female Reed Bunting was seen in the sedges and reeds, Willow Warbler, Chiff Chaff and Blackcap were all singing. Overhead and in the Alder trees Siskins and Redpoll were seen and heard and Swallows were hawking for insects over the water.

On Crabtree Hill several Tree Pipits were singing rather half-heartedly, Linnets were in evidence, a Great Spotted Woodpecker was seen/heard briefly. Other birds noted were Chaffinch, Blackbird, Goldcrest, Carrion Crow, Robin, Wren, Song Thrush, Tree Creeper, Jay, Wood Pigeon, Coal Tit and Buzzard.

Butterflies were represented by Green Veined White, Orange Tip and Speckled Wood.

Cinderford Northern Quarter visit 12th April 2014

Andrew Bluett was joined by Colin & Ingrid Twissell, Nick Christian, Simon Glover and Councillor Andrew Gardiner for the third visit to the Cinderford Northern Quarter development area.

Andrew Gardiner was able to show us LiDAR (Light Detection & Ranging) aerial photographic images of the area which depict details of the ground contours and irregularities across the site. The significance of these images amongst other things is that they show depressions in the ground indicating the positions of some of the numerous shafts and holes resulting from past mining activity.

Simon Glover had previously made some exploratory visits to parts of the site seeking these depressions and evidence of “sink-holes” or collapse where some subsidence is in progress.

As a result of both the LiDAR images and Simon’s findings the party was able to locate and examine a number of the surface depressions, some of which showed recent evidence of movement, no doubt aggravated by the heavy rainfall and flooding that had affected Gloucestershire and many other areas in the late winter.

The CNQ site has been the subject of a detailed mining & excavation investigation by expert Paul Morgan, and whilst there is some disagreement regarding his findings, there is no doubt that historically the site has been extensively mined both with shafts and by opencast extraction and has been the site of opencast clay extraction for the local brickworks. It is believed that there is a significant aquifer under the area which could aggravate the deterioration of the ground in some areas. Estimates vary but the belief is that there are over 130 uncapped shafts on the site and could be more than twice that number.

The weather was bright but cloudy and chilly so no reptiles were evident; bird life was much the same as on previous visits but with the addition of some of the first of this spring’s Willow Warblers, newly returned from their southern winter quarters. Siskin & Crossbill were seen and heard overhead and a new addition to the species list was Pheasant. Ingrid Twissel had identified another species of fungus, the toxic and scarce (in southern areas) Gyromitra esculenta.

Field meeting at Forthampton Oaks

The latest GNS field meeting took place on 30 March at Forthampton, just across the Severn from Tewkesbury. The main point of interest was the Forthampton Oaks Key Wildlife Site, listed as a KWS because of the rare invertebrates found in the oaks by GNS recorders in the past.  The oaks are very aged, some of them dead, on the top of a ridge overlooking the Severn, but the parkland surrounding Forthampton Court supports a large number of healthy oaks in the hedgerows and open country.

There is a variety of different habitats within a small compass, including the old brickpits at Lower Lode, a series of arable fields, and low-lying hay meadows along the river.  Signs of the recent gales and heavy flooding were apparent, with a number of trees down and high water marks showing just how far the flood had extended.

Among the birds seen were: on the brickpits at least 20 Cormorants loafing in the trees, several of them in bright nuptial plumage, while on the water surface a pair of Mute Swans were already building a nest, and about 20 Tufted ducks and a Great Crested Grebe were present; over the arable, half a dozen Lapwings were beginning their spring aerial display, an increasingly rare sight in the Severn Vale, while a Shelduck may have been looking for a nesting hole and two Egyptian Geese sat placidly by; in the parkland, the highlight was a singing Lesser Spotted Woodpecker; in the hay meadows a pair of Curlews were holding territory and participants listened to their lovely bubbling song; along the river bank, about 20 Sand Martins had already returned from their African wintering sites, and singing Chiffchaffs were everywhere.

This early in the season, botanical interest was limited, but there was much blackthorn in flower in the hedges; Ground Ivy, Dandelion, White Violet, Daisy, Lady’s Smock and Lesser Celandines were out, and a very aged Black Poplar was admired.  Weeds in the arable included Chickweed, Red Dead Nettle, Shepherds Purse and Groundsel.  The most interesting plant, besides the oaks and the poplar, was the dried stems of Thorn Apple which probably came in with maize seed; this may be a first record for the hectad, as there are only 11 dots for the county in the Bishop “Flora of Gloucestershire”.  The Lichen Recorder felt that the site deserved another, more leisurely visit.

On the way back, the eight participants admired a lovely view of Tewkesbury Abbey, framed in trees behind a long reach of the Severn.

GNS will liaise with the Key Wildlife Sites database (managed by the Gloucestershire Wildlife Trust) to ensure that information on this important site is up to date.
