the two hills where the farm was located has an unusual flora. Amongst dense bracken is balm-leaved figwort (Scrophularia scorodonia), common here but not found elsewhere on the island and an unidentified yellow, cultivated rose. A second alien, Argentine dock (Rumex frutescens) grows on the edge of a sand pit which was originally intended to be a reservoir. The fields below the two houses were, before 1933, fertilised with "shoddy" – a high nitrate manure derived from the woollen industry. Within these fields can be found viper's-bugloss (Echium vulgare), common melilot (Melilotus officinalis) and wild mignonette (Reseda lutea). All three are thought to be imported arable weeds. In the 1960s the "neck" was a closely cropped sward of grass but after myxomatosis the area became overgrown with bracken and bramble. In October, 1972 a fire on Kittern Hill burnt through the shallow peaty soil to the granite. Bleached stones and blackened gorse stems can still be seen and the vegetation has not recovered sufficiently to equal the waved heath elsewhere on Scilly. Heath is on the hills on both sides of “the neck” and in the south of the island the nationally rare orange bird's-foot (Ornithopus pinnatus) can be found as can rare lichen species such as Lobaria pulmonaria and golden-hair lichen (Teloschistes flavicans). Rare plants Shore dock (Rumex rupestris) first discovered here in 1893 by John Ralfs still extant in the 1960s but now extinct. Small adder's-tongue (Ophioglossum azoricum) has not been seen since at least the mid-1980s. The site was on the east coast between Carn Kimbra and Point Witcher. The only area of the SSSI that was classified as "favourable". Four-leaved allseed (Polycarpon tetraphyllum) was recorded by Lousley in 1939 and 1940. Fauna In July 1924, W. N. Blair caught a shrew which he did not recognise and sent a specimen to the British Museum for the attention of Martin Hinton, who identified it as the lesser white-toothed shrew (Crocidura suaveolens). Known as the "Scilly shrew", the type specimen is held by the British Museum. The other mammals found on Gugh are feral cats, rabbit (Oryctolagus cuniculus) and possibly the house mouse (Mus musculus). Permanent monitoring stations, consisting of boxes with chocolate wax inside, have been set up around the coasts of both Gugh and St Agnes and a baiting grid will be set up around any signs of rats. As of 2015 the brown rat is
