Just out: a two-volume set on conservation of North American crop wild relatives! Adam had the honor of contributing to a chapter on threat assessment. “This chapter introduces the roles of conservation status and threat assessments in informing conservation priorities for crop wild relatives in North America and provides an overview of the current results for US taxa.” Some key results: Residential development is the most common threat to crop wild relatives in the US, followed by fire/fire suppression, then invasive species.
