Publication of new chapters of SSSI selection guidelines: lichens and fungi
Chapters 13 (Lichens and associated microfungi) and 14 (Non-lichenised fungi) of the SSSI selection guidelines were published recently.
Fungi – main changes
New criteria for:
- Globally threatened taxa (IUCN Red List)
- GB and country-level IUCN red-list threatened species
- Coastal sand dune fungi
- Tooth fungi associated with oak, beech or sweet chestnut
- Caledonian pinewood fungi
- Beech deadwood fungi
- Oak deadwood fungi
The grassland fungi chapter (2009) has been updated and included as Section 4, with tighter criteria and predefined species lists/concepts for scoring.
Lichens – main changes
- Replacement of the site scoring system (Combination of Species) with habitat-based assemblage scoring (assessment of ecologically coherent assemblages)
- Adoption of new lichen habitat indices for: heathland & moorland, limestone, maritime rock, watercourses, metalliferous habitats and pinhead lichens (deadwood habitats)
- Refinement of woodland lichen indices, including adoption of new index names
- Criteria for lichens that are Threatened on the global IUCN Red List
- Introduction of a new criterion for taxa that are Near Threatened for which Britain has International Responsibility (including endemics and near-endemics)
- Evaluation of species with a Threat status in country-level red data lists (where available)
- The value of non-native trees is covered in an appendix
The presence of WCA Sch. 8 species is no longer a reason to notify in either chapter. In the absence of country-level red lists, NERC Sect. 41 species are included in the fungus chapter.
