Abstract
Habitats sensitive to anthropogenic pressures
are growing in conservation importance in the protection and perpetuation of
rare animal and plant species. Although natural habitats sensitive to
disturbance in urban areas have mostly declined in availability, patches offer
conservation opportunities for wildlife that are fundamental to maintaining
biodiversity. Human burial sites can contribute to this: they are more numerous
and greater in extent in more urbanized areas, but their significance in the
maintenance and promotion of biodiversity has not been considered across Europe
and other continents. Because of their high sensitivity to even minor
disturbance to natural habitats, orchid diversity is a key bioindicator of
terrestrial ecosystem function. We evaluated orchid diversity in cemeteries of
13 European countries. Comprehensive field surveys of orchid flora in 2079
locations revealed that they occurred in every country visited and in high
variability in both the number of taxa (n = 65) and individual plant counts (n = 44680). We propose that cemeteries are of major importance as refugia in
conserving orchids in most of the visited European countries; however, one of
the most urgent issues is to identify the many anthropogenic factors
determining biodiversity of cemeteries, and to eliminate some newly emerged management
practices in cemeteries that undermine biodiversity, including the orchid
flora. Human burial grounds are therefore not just important in preserving the
history of humankind; they are key in protecting biodiversity in this modern
era of unprecedented anthropogenic changes to our terrestrial environments,
especially as a result of rapid and unrelenting urbanization.
