Red Data Book 3 (RDB3) At Risk: species which are known or thought to exist in fifteen or fewer
10 km squares in the U.K. and have been recorded in these squares since 1970.
English Nature also use the category Notable for other scarce but less vulnerable species, split into
two categories Notable a and Notable b.
Table 1 (below) is a list of 50 invertebrates recorded from Epping Forest over the last 150 years.
The list is selected to include thirty of the national rarities recorded from the Forest with their current
conservation status (RDB1-3). It is not known how many of these still survive in the Forest. Rarities
are readily discovered in the Forest - the small beetle Batrisodes buqueti was found in 1987. Its only
other known location in Britain is Windsor Forest. Many of the RDB species on this list are confined
to ancient woodland. Other species on the list have been selected for their rarity in Essex. Many of
these are designated as notable by English Nature. I have also selected the species on this list to cover
as wide a range of wood-pasture habitats as possible. Much of the information on this table was
gathered by the Nature Conservancy Council for the Invertebrate Site Register, Report No. 99 Epping
Forest (1987).
