Plant Endemism Assessment of Red List Habitats in Europe (PEARL), Endemic
Vascular Plants in Europe (EvaplantE), and a database on hyperendemics
(Hypedata).
The first two are available on the internet, the latter are databases which are
regularly updated by our working group. EvaplantE is a list of vascular plant taxa
which are restricted to Europe. For example Hobohm and Bruchmann (2009)
published an analysis which is related to a former version. PEARL is a list of all
vascular plant taxa that are characteristic for predefined groups of Red List habitats
in Europe (cf. Janssen et al. 2016) and the relating fact sheets. The main work on this
list was on taxonomy. Taxon-habitat relations are defined by the combination of a
taxon with a habitat type. The fifth database is a global list on hyperendemics
(appendix represents an extraction). To get information on hyperendemics, we
analyzed the IUCN Red List (2019a, b, c). Furthermore, we began to communicate
with ecologists of certain biogeographical regions and/or taxonomic groups, and
tried to implement a pyramid scheme. The personal communication began
unsystematically, later on we will try to find a more systematic scheme.
The results of the analyses of all five databases indicate the meaning of predefined
groups of habitats for the existence and survival of endemic and threatened species
(Table 2).
Threats and numbers of endemics or threatened species of vascular plants and
vertebrates are presented for the following groups of habitat types: marine intertidal/
coastal/saline, freshwater, bogs/mires/swamps, grassland, scrub/heathland, forest/
woodland, sparsely vegetated rocks/screes/desert, arable, and urban/horticultural
land.
