摘要:We identified high-value biodiversity areas (HVBAs) of terrestrial
vertebrates according to a combined index of biodiversity (CBI) for each
major taxon and a standardized biodiversity index (SBI) for all taxa in
2195 cells of 50 × 50 km
in Western Europe to evaluate whether these areas
are included in the current protected area networks. The World Database on
Protected Areas (WDPA) and NATURA 2000 protected area network were used to
assess the protected area cover in HVBAs. WDPA and NATURA 2000 were
geographically quite complementary as WDPA is more densely represented in
Central and Northern Europe and NATURA 2000 in the Mediterranean basin. A
total of 729 cells were identified as HVBAs. From the total of these HVBA
areas, NATURA 2000 network was present in more cells (660) than the WDPA
network (584 cells). The sum of protected land percentages across all
the HVBA cells was 28.8%. The identified HVBA cells according to the SBI
included 603 or 78.2% of all vertebrate species in the study region,
whereas the identified HVBA cells according to the SBI for individual taxa
included 47 (90.4%) species of amphibians, 79 (74.5%) of reptiles, 417
(88.5%) of birds, and 130 (91.5%) of mammals. However, neither network
was present in 7 or 3% of the identified HVBA cells. Thus, we recommend
expanding protected areas in Europe to fill this gap and improve coverage of
vertebrate species to strengthen biodiversity conservation.
