NIMBioS Study Finds Saving Seeds the Right Way Can Save the World’s Plants

 

Exotic pests, shrinking ranges and a changing climate threaten some of the world’s most rare and ecologically important plants, and so conservationists establish seed collections to save the seeds in banks or botanical gardens in hopes of preserving some genetic diversity.

A National Institute for Mathematical and Biological Synthesis study, however, has found that more careful tailoring of seed collections to specific species and situations is critical to preserving plant diversity. Once seeds are saved, they can be reintroduced for planting in suitable locations if conditions are favorable. For more information on the study, visit the NIMBioS website.
