established well and has thrived. This population has since served as a source for the natural re-colonisation of other parts of the county, with the exception of the Offord D’Arcy population which was planted in the 1950’s. Many of these other populations have also been long established, for example a colony has been known at Morborne Hill since at least 1964. Given that this species has been re-established in the county for almost 100 years, it is surely time now to stop maligning it with alien status and instead appreciate it for what it is, a nature conservation success story. While the reintroduction of this species was carried out long before the procedures and standards for conservation re-introductions were established, it might be constructive to treat it as one nonetheless. With the development of the Great Fen Project this species future in Huntingdonshire has probably never looked so bright. Sorbus torminalis (L.) Crantx. Wild Service-tree National Status: Not scarce, not threatened County Status: Scarce (5 sites, 11 tetrads) Site Grid Reference Last Record Archer’s Wood Nature Reserve TL174812 2009 (DB) Aversley Wood SSSI TL164822 2008 (DB) Gamsey Wood Nature Reserve TL2281 1996 (TW & SW) Monks Wood SSSI TL190795 76 TL19438007 TL201808 Upton Wood TL17997986 TL18007989 2008 (DB) 2009 (DB) 2009 (DB) 2010 (MiB) 2010 (MiB) This easily overlooked tree is widely but sparsely distributed in, and indicative of, ancient woodlands on the boulder clay. I have attempted to list only native populations. In the future, distinctions between native and introduced populations may become clouded as a result of plantings e.g. at Lady’s Wood, Littless Wood and Ramsey Heights Clay Pits. This point has been reinforced by NM, who informs me that the Brampton Wood trees listed in previous editions of the RPR of planted origin. Stachys arvensis (L.) L. Field Woundwort National Status: Near Threatened County Status: Rare (1 site, 1 tetrad) Site Grid Reference Last Record Colne, allotments TL384753 1998 (SW) Although this species remains frequent over much of its British range it has declined in some areas, probably as a result of increases in winter cropping, the use of broad-spectrum herbicides, increased use of nitrogen-based fertilisers and the planting of more competitive crop cultivars (Wilson & King, 2003). It has always been rare in Huntingdonshire (Wells, 2003).
Stellaria alsine Grimm. Bog Stitchwort National Status: Not scarce, not threatened County Status: Rare (3 sites, 5 tetrads) Site Grid Reference Last Record Agdengreen Wood TL146622 1998 (BD & JaC) Aversley Wood SSSI TL15718157 77 TL16118220 Woodwalton Fen SSSI & SAC TL22888383 TL23078408 TL2284 2008 (DB) 2010 (DB) 2008 (DB) 2009 (DB) 2010 (MM) The classic location for this species in Huntingdonshire is Woodwalton Fen where it is widespread and locally abundant. In recent years new populations have been found on damp ancient woodland rides, a typical habitat in neighbouring counties, and there may be a few more new populations waiting to be discovered at such sites. Stellaria neglecta Weihe Greater Chickweed National Status: Not scarce, not threatened County Status: Rare (3 sites, 3 tetrads) Site Grid Reference Last Record Lady’s Wood Nature Reserve TL24278249 2011 (DB) Raveley Wood Nature Reserve TL245818 2010 (SW) Woodwalton Marsh SSSI, entrance gate TL21238118 2011 (DB) Very abundant in Lady’s Wood. There is a historic record for Holme Fen, but Myosoton aquaticum is abundant there so future determinations need to be made with care. It is not unknown for Myosoton to be erroneously recorded as Stellaria neglecta. Stellaria pallida (Dumort.) Piré Lesser Chickweed National Status: Not scarce, not threatened County Status: Rare (2 sites, 2 tetrads) Site Grid Reference Last Record Huntingdon, Millfield Court TL233714 2011 (KW & LF) Paxton Pits TL19916255 2010 (DB) Portholme, sluice over the Alconbury Brook TL23717129 2009 (DB) This diminutive, annual species can be found in short turf or on sparsely vegetated ground, particularly in association with mineral rich soils. There is a suggestion of an affinity with populations of Cerastium semidecandrum, so it should be searched for wherever this species occurs. The population at Portholme may have been introduced with gravel.
