Struggling to conserve seed biodiversity: the gaps and wisdom in current research

: When humans develop landscapes, they break up habitat that is home to native plants and animals. To assist flora and fauna populations to continue to exist there, it is necessary to enable them to move between the newly isolated remnants of habitat. To help species persist, they recommend linking habitat fragments with strips that will support the species. At the very least, habitat “stepping-stones” should be established. Overharvesting : Though animals harvest seeds, they also help spread them. Thus, overhunting animals can be just as detrimental to seed dispersal as harvesting the seeds directly. Plant and animal populations should both be monitored to maintain seed biodiversity. For those species essential for seed dispersal, the authors suggest managing for “a population size that maintains their ecological function, rather than merely the minimum viable population....
