Collecting seeds from wild rare plant populationsMaschinski, Joyce; Walters, Christina; Guerrant, Ed; Murray, Sheila; Kunz, Michael; Schneider, Heather; Affolter, Jim; Gurnoe, Tony; Fraga, Naomi; Havens, Kay; et al. (Center for Plant ConservationEscondido, California, 2019)Species characteristics, legal parameters, and the purpose of the collection influence decisions about timing, locations, and numbers of seeds (or other tissues) that will need to be collected. Ethics of doing no harm to the wild rare plant population guide actions in the field....
Genetic guidelines for acquiring a conservation collectionMaschinski, Joyce; Walters, Christina; Guerrant, Ed; Murray, Sheila; Havens, Kayri; Font, Jeremie; Kramer, Andrea; Vitt, Pati; Neale, Jennifer Ramp; Guerrant Jr., Edward O.; et al. (Center for Plant ConservationEscondido, California, 2019)Planning the quantities to collect from one population and across the range of species will improve the chance of maximizing the genetic diversity of the conservation collection. Maintain maternal lines separately to help approximate potential genetic diversity and allow flexibility for use in future conservation translocations. Collect no more than 10% of a population’s seed crop in a single year and no more than 5 years out of 10.
