 Record Name A return visit to Bellerby Moor.
 Record Description NOTE! Public Access to the Army Ranges on Bellerby Moor and other live firing areas of the Catterick and Feldom Ranges is only possible with express permission from the Range Officer. This record will introduce the rich flora which survives in the vicinity of Park Gill Beck and the tufa springs located on the Swale/Ure interfluve at the head of Park Gill Beck south of Black Beck Gill.The flora at these spring flushes was first noted by English Nature in 1993 during their 'major survey of areas of the North Pennines'. The nationally scarce and botanically rich tufa and oncolite-forming springs at the head of Park Beck and the presence of Stonewort (Chara sp) in Park Gill Beck were specifically noted during an archaeological walk-over survey carried out during the winter of 1992/3 by SWAAG Members in advance of the construction of a new Range, see a total of 18 earlier SWAAG Database Records (Search for Bellerby Moor). However the winter season was not suitable to record the flora and it was resolved to record the plants in flower at the first opportunity, hence this revisit.

 Geographical area Wensleydale
 Species Birdseye primrose. Marsh pimpernel. Least clubmoss.
 Scientific Name  Primula farinosa. Anagallis tenella. Selaginella
 Common / Notable Species Colonies of a Stonewort (Chara sp) - provisionally identified as Chara aspera- were present intermittently throughout the length of Park Gill Beck above Park Gill. The water level was low and these colonies had in part dried out. The locally very rare Water Speedwell (Veronica anagallis-aquatica)was seen both at Park Gill and within Black Beck Gill. Large colonies of the scarce Flat Sedge (Blysmus compressus were seen intermittently throughout the whole length of Park Gill Beck above Park Gill and in Black Beck. Full list of plants to follow.
 Additional Notes During this visit a number of plants were recorded which are either locally scarce or have not been recently recorded in the most recent available Flora of Wensleydale (Reference: Deborah Millward 1988. A Flora of Wensleydale. The Yoredale Natural History Society). A full list of the plants seen during this visit has been prepared by Mrs Linda Robinson, BSBI Regional Recorder for North Yorkshire (Vice County 65) and Botanist to the Catterick and Feldom Ranges Conservation Group. This list will be made available to the Army Range Conservation Group at their next meeting in September.
