  • Thank you for comingHonor to have the opportunity to present some results to this communityCollaboration between national agencies, international research centers and academic institutionsReinforce two points then ask a question
  • CWR of the US are no exception- many cases of use in breedingPhylloxera resistance grapes from N. American wild grape rootstockEnglish walnut rootstock- JuglanshindsiiCWR native to the US are related to a sizable list of crops of significant importance to US agriculture
  • Habitat degradation, urbanization, pollution, invasive species, climate changeFederally listed Endangered:Okeechobee gourd (FL),Scrub plum (FL), Texas wild rice (TX)Federally listed Threatened:Pecos sunflower (NM, TX)
  • Native and introduced species (12% of inventory) includedClosely and distantly related CWR includedAvailable as a download from GRIN website, and will be incorporated into GRIN interactive site eventuallyNecessary to prioritize
  • who
  • whereOccurrence data from global dataset- herbaria and genebanksFor information on methodology, see Phaseolus paper
  • Maxent models based upon occurrence dataConstrained to native areas (state level)Cross validated
  • where
  • where
  • How well conservedConservation analysis from a national perspective- priorities analyzed for US distributions.
  • Collecting gap maps = distribution models minus areas where collecting has already occurred (CA50)
  • How well conservedCollecting gap richness maps for HPSReminder this does not pertain to conservation status in situ- upcoming analysis. 28% of the US is owned by the US Federal Government.
  • Ongoing CWR collecting by USDA ARS NPGS- national germplasm system- largest in nation and service provider for the world’s plant breedersUSFS- nation’s largest landownerGenetic diversity analyses underway- Juan Zalapa ARS Cranberry Genetics and Genomics Lab Madison, WisconsinConservation ex situ- Kim Hummer, curator of the National Clonal Germplasm Repository in Corvallis, OregonIn situ planningNext steps:Expert inputsIn situ conservation analysesMaking data useful for on the ground effortsCollaborating with diverse agencies, land owners, organizations
