There are immediate barriers to the full recognition of fungi within focused conservation management actions and overall priority-setting. These include the insufficient baseline data on distribution and the lack of formal conservation assessment (i.e. red-listing). Despite various efforts over the years, very few non-lichenized species have formally endorsed assessments under national legislation, and international assessment under IUCN guidelines has also been carried out for only a handful of species. A large proportion of the British species of non-lichenized fungi have insufficient distributional information for a clear assessment of threat, due to insufficient recording activity with very large numbers of species and a shortage of expert surveyors/identifiers. These would currently be considered as Data Deficient under the formal guidelines.

Most of the species pages in this website have some indication of conservation status. For almost all non-lichenized species this is an informal analysis of existing data, which may provide a pointer towards assessment in the future but which is not intended to take the place of a formal study. All the species targetted under the Lost & Found Fungi project will have formal assessments once the data gathering phase is complete.

Links are given below to red-lists and other information relevant to the British mycota. Red-lists are a snapshot in time, and of course become outdated more or less immediately they are published. Nevertheless, they are valuable documents which are used on a regular basis in conservation decision-making.
