 Site Description Arlington Park and Woods comprises a large ancient park overlying Devonian slates, largely occupying south-west facing slopes at 100-180 m within the valley of the River Yeo, on the edge of Exmoor. Beech (Fagus sylvatica), Ash (Fraxinus excelsior) and Oak (Quercus spp.) are the key tree species present, though Alder (Alnus glutinosa) and Sallow (Salix spp.) occupy an area of dense wet carr woodland within the site.

 Botanical Significance Noted for lichen interest. The park and woodland is of high botanical importance on account of its rich lichen flora, with many rarer species. The ancient parkland and willow carr provides a diversity of habitats for lichens, and supports a number of rare western and old-forest indicator species.Rare and threatened species present include: Anaptychia ciliaris (VU), Bacidia incompta (VU), Enterographa sorediata (E, VU, IR), Lecanographa amylacea (VU, IR), L. lyncea (IR), Lobaria amplissima (IR), Opegrapha prosodea (NT, IR) and Wadeana dendrographa (NT, IR). Additionally, Natural England notes: “Of particular note here is the development of Cetrelia olivetorum and Heterodermia obscurata which is the best in south-west England. Also important is the presence of Teloschistes flavicans, one of only two localities for this species in Devon outside the southern coastal area. Rare species include Bombyliospora pachycarpa, Pannaria conoplea, Parmelia lacinatula, Sticta dufourii and Lecidea carrollii. The Lobarion community is well represented and the site is also noteworthy for an abundance of Usnea articulata.”

 Conservation Issues One part of the site (c. 10 ha) reported to be suffering from eutrophication following fertiliser application to grassland (2005). Otherwise site deemed to be in favourable condition by Natural England in 2005, with very extensive beef cattle grazing under parkland trees, and a programme of young tree planting (as replacements for older trees over time).
