e determined whether or not a self-sustaining population has established. Given this species national status and the availability of plentiful seed of local native origin it would be desirable to see an attempt made to re-establish this species on Woodwalton Fen. Digitalis purpurea L. Foxglove National Status: Not scarce, not threatened County Status: Rare (2 sites, 3 tetrads) Holme Fen SSSI: Compartment 1 Compartment 8 Site Grid Reference Last Record 30 TL1989 TL200893 2006 (MM) 2009 (DB) Monks Wood SSSI TL193800 2006 (KW) This species is dubiously native in the County and the above list excludes the many records of obvious garden escapes. Even at Holme Fen, where the habitat conditions might indicate a plausible native population, plants seem too robust for good native stock and may be a long naturalised garden selection. Diplotaxis tenuifolia (L.) DC. Perennial Wall-rocket National Status: Not scarce, not threatened County Status: Rare (1 site, 1 tetrad) Site Grid Reference Last Record Conington, near the railway TL208831 2009 (SL) This is the only established population of this archaeophyte in the County, with other historic occurrences being relatively short-lived. It has been known from this general area since at least 1948 and occurs with a range of other interesting calcicole species. Dipsacus pilosus L.

It can be reasonably tolerant of deep shade provided there is sufficient disturbance to encourage seeds to germinate. Some of the strongest colonies are in unprotected sites, e.g. Hamerton Grove and Salome Wood, while perversely those populations present within protected sites are often markedly smaller and more isolated in occurrence.

All our plants have been identified as, or are believed to be, the above species, but it is possible that Dryopteris affinis sens. str. may also occur. Dryopteris carthusiana (Vill.) H.P.
