THORNE MOORS VERTEBRATES RECORDS 2006
compiled by Martin Limbert

1. Parameters of conservation. Thorne Moors lies within the Humberhead Levels Natural Area, and the peatland and contiguous wetlands comprise the Thorne Moors Site of Special Scientific Interest. The moorland forms a component of the Humberhead Peatlands National Nature Reserve, managed by Natural England and (in the North Lincolnshire section q.v.) the Lincolnshire Wildlife Trust. The NNR has international designations to recognize its conservation importance.
2. Recording area. For vertebrates documentation, the Thorne Moors recording area is deliberately interpreted somewhat loosely. It comprises the whole of the peatland, contiguous unfarmed areas, the Thorne Colliery curtilage, and peripheral farmland and drains. The limit to the north is defined as the line of the old Axholme Joint Railway. Otherwise, a field width or so is a practical rule-ofthumb.
3. Place-names. In broad terms, the name Thorne Moors is used to embrace both the peatland and the other areas under study. The surviving peat is divided by parish limits, the parish names being Thorne Waste, Snaith & Cowick Moor, Rawcliffe Moor, Goole Moor and Crowle Moor. Thorne Waste (except now the Yorkshire Triangle) lies in South Yorkshire, and the other parishes lie in East Yorkshire, except Crowle Moor and the Yorkshire Triangle, which are in North Lincolnshire. That part of Goole Moor situated north of Rawcliffe Moor is designated as ‘Northern Goole Moor’ for recording purposes. Within the parish framework, numerous place-names are employed for vertebrates recording. These names were included on the place-names map issued with the Thorne Moors Vertebrates Report 2005.
4. Current sources of nomenclature and species sequence. In this report, English and scientific names and sequence of species accord (where appropriate) with the following:
Beebee, T.J.C. and R.A. Griffiths (2000) Amphibians and Reptiles. A Natural History of the British Herpetofauna. The New Naturalist No. 87. London: HarperCollins Publishers.
The British Birds List of Birds of the Western Palearctic; see www.britishbirds.co.uk/bblist.htm (accessed 10th February 2007).
Arnold, H.R. (1993) Atlas of mammals in Britain. Institute of Terrestrial Ecology Research Publication No. 6. London: HMSO.
In addition, botanical nomenclature and sequence follow:
Stace, c. (1997) New Flora of the British Isles. Second edition. Cambridge: Cambridge University Press.
5. Descriptions. For nationally rare avian taxa, descriptions and visual evidence should be made available in accordance with the requirements of the British Birds Rarities Committee. At county level, material should be prepared in compliance with the lists issued by the Yorkshire Naturalists’ Union Ornithological Section Reports Committee or the Lincolnshire Bird Club, as appropriate. Advice and blank forms can be made available upon request.
6. Rare breeding birds. In addition to Natural England, records of rare breeding birds are made available to the county organizations, and via them to the Rare Breeding Birds Panel. Records may also be accessed by bona fide specialist study groups.
7. Daily counts. In the species accounts which follow, there are references to "daily counts" and "counts". It is emphasized that these are not full site counts, but counts made by an individual observer or group on a particular date. It is possible to have more than one count on a single date, when the highest will be used if they cannot be united. The recording area is very large, and site totals are difficult to establish with certainty, except for the scarcer species. However, for some wetland birds, it is possible to visit the most likely places to count these species, thus attaining a relatively accurate moorland total for them. It is acknowledged that such reported daily counts may sometimes be regarded as vague, but they are broadly comparable over a period of years.
VERTEBRATES RECORDING IN 2006
1. Number of records submitted. The number of records of vertebrates communicated for 2006 was relatively low, preventing the production of a full annual summary. Therefore, only significant records are detailed here and not all species are mentioned.
2. Statistics for 2006. During the year, three species of reptile, 127 species of bird and 10 species of mammal were reliably reported from Thorne Moors. Because of the low level of record submission, there were few notified birds of major significance. However, Little Egret was an addition to the site list. Other birds of note included Common Goldeneye, Common Quail, Black-necked Grebe, Red Kite, Little Gull and Snow Bunting. Conversely, several summer migrants were in very poor numbers. Interesting breeding records were obtained, including Tufted Duck, Common Stonechat and Eurasian Treecreeper. There were no especially noteworthy records amongst the other vertebrates, though 12 Adders were counted on 18th April.
3. Publications, reports, etc. The following references appeared during 2006, using vertebrates data concerning Thorne Moors, but not necessarily relevant to that year. Published references to noteworthy species as news items are not detailed (unless accompanied by an image), nor are those references in which the site allusion is merely incidental or very minor:

Brown Hare Lepus capensis. Reported in April from Snaith & Cowick Moor and Goole Moor, singly except 2 on Snaith & Cowick Moor on 12th. The only other record was 1 along Will Pits Tram on 23rd June.
Water Vole Arvicola terrestris. On 18th April, 1 was in the drain at the base of the Thorne Colliery spoilheap, alongside the track to Whaley Balk.
Stoat Mustela erminea. One was in a flooded area at the western edge of Will Pits on 13th March. Another was encountered along Mervyn’s Tram on 7th April. On 5th October, 1 carried a Moorhen Gallinula chloropus on the road alongside Swinefleet Warping Drain at Will Pits. Next day, 1 was in the Yorkshire Triangle.
Weasel M. nivalis. On the road alongside Swinefleet Warping Drain at Will Pits, singles were seen on 7th March and 23rd June, the latter carrying what was probably a Field Vole Microtus agrestis.

21st November: A stag and 2 hinds at Will Pits.
22nd November: 4 hinds at Will Pits.
18th December: 2 hinds at Will Pits.
Roe Deer Capreolus capreolus. Occasional records January-March involved 1-2 in the Will Pits area and in the Snaith & Cowick Moor-Rawcliffe Moor area. From April until June, singles, sometimes 2 or 3, were encountered widely. Locations included arable fields alongside the western and north-western moor edges, and even Moorends Recreation Ground, where a buck was seen on 25th May. In addition, there were counts of 7 on 12th April (4 on Inkle Moor and 3 at the Alder Woods), 18th April (including 5 on Goole Moor) and 14th May (including 5 at Will Pits). Evidence of breeding comprised a juvenile with an adult in a field east of Bank Top on 23rd June, a fawn at the Pony Bridge on 28th June, and a doe with twins (quite large) at Will Pits-Bank Top on 22nd November and next day along Mervyn’s Tram. There were several records of up to 3 during October-December, mostly in the Will Pits area.

EFFECTS OF DEER ON EPIPHYTIC BRYOPHYTES
The recent increase in epiphytic bryophytes (mosses and liverworts) in lowland South Yorkshire, possibly due to decreases in sulphur dioxide levels, is nowhere better reflected than on Thorne Moors, in particular Will Pits and Pony Bridge Wood. In a forthcoming paper (Thorne & Hatfield Moors Papers 7), I have documented the incidence of 12 new epiphytic bryophyes, some of them rare, in Will Pits and Pony Bridge Wood. In addition, since the paper was written, Radula complanata (L.) Dumort., a liverwort first found in vice-county 63 on Inkle Moor in 2005, now occurs at two stations in Will Pits on willow Salix. Almost invariably, the new epiphytes appear to colonise fairly recent willow growth, in particular horizontal or inclined branches of c.10cm in diameter. The boles of the older trees are avoided, either because they are already covered by common, mat-forming epiphytes, or possibly because of accumulated pollution already contained within their bark.
During a visit to Will Pits and Pony Bridge Wood in April 2006, I was concerned by the degree of damage to the bark of willow trees and shrubs by the deer population. Both Red Deer Cervus elaphus and Roe Deer Capreolus capreolus occur, and recently Muntjac Muntiacus reevesi has been noted. On the visit, it soon became evident that, by a depressing coincidence, virtually all the fraying and ring-barking was confined to the same branches that were most receptive to bryophyte colonization i.e. outgrowths from the main bole. The situation had markedly worsened since 2005, and in some areas of Pony Bridge Wood it was difficult to find an undamaged tree.
The deer have no natural predators, and unless some control is exercised, it seems reasonable to suppose the population will continue to expand. Since Will Pits and Pony Bridge Wood are the main breeding sites and areas of greatest concentrations, the damage will certainly continue until only the older trees with densely fissured bark will survive, with all new growth either dead or dying. It is ironic that the deer ignore the birch Betula, and their preference for willows must inevitably lead to yet more birch-dominated woodland. These woods in mid-summer have a subtle ‘jungle-like’ feel to them. This is a quite magical quality produced by an established plant association on wet warpland in which willows dominate. If the willows are lost, the character of the woodlands must change for the worse and become birch or possibly even Rhododendron Rhododendron ponticum dominated.

REQUESTS FOR INFORMATION
Since 1998, Black-necked Grebes have occurred on Thorne Moors, with confirmed breeding from 2001. All records are requested of this species, giving as much information as possible, including behavioural data.
In recent decades, Red Deer have been encountered on Thorne Moors since the 1960s, and there has been a continuous presence from 1994. The maximum count on and around Thorne Moors was obtained in 2004, when 35 head were seen on one date, presumably representing a large percentage of all Red Deer resident on that day. It is believed that the change in status of this species is largely allied to the regional growth of deer farming, with resultant deer at large in the countryside. In the Thorne Moors area, Red Deer may now be watched in fields, and on the moorland, especially in the Will Pits area. All records of Red Deer, past and present, are being collated for population monitoring and possible future analysis. Accordingly, as much detail as possible is required when documenting Red Deer.
