  2. 2. Strategy Flowchart source: adapted from Maxted N. various publications
  3. 3. Inventory of CWR of the US Khoury C K, Greene S,Wiersema J, Maxted N, Jarvis A, and Struik P (2013) An Inventory of Crop Wild Relatives of the United States. Crop Sci. 53(4): 1496. doi: 10.2135/cropsci2012.10.0585.Available online at:
  4. 4. Inventory media coverage
  5. 5. 2256 taxa of 176 priority genera occur in the USA 821 taxa of 69 Priority 1 genera related to 63 crops 285 taxa of 30 genera 1A (closely related native taxa) 536 taxa of 57 genera 1B (distantly related, non-native) Priority 2 genera- 1435 taxa from 107 genera note this is a massive undertaking- global project 29 gps- 485 taxa; 90 gps- >1000 taxa Taxonomic Priorities for the US Rubus hawaiensis source:
  6. 6. Gap Analysis Methodology Determine gaps Model distributions Gather taxonomic data Gather occurrence data Make conservation recommendations Georeferencing
  7. 7. Global project occurrence data Online data, genebanks, herbaria, researchers and experts Herbarium visits- 15,713 records digitized from photos taken at NY, PH, US, MO, CAS, UC, WAG, CUVC, R, RB, MA, COI, RBGE, LISU, LISC, LISI, BM, RBGE, P,  L, K, VIR. Data collected by genus- 194 genera in total, including 18 specific only to US priorities Data cleaning and processing Taxonomic verifications- TNRS, TaxStand, final check by hand Coordinate verification and georeferencing- 321,000 records successful. Database- 5.4 million records, including >3 million records with “good” coordinates
  8. 8. Occurrence data- global dataset

  20. 20. Gather more occurrence data for P1As- GBIF extras run code again for P1As Develop methodology for in situ conservation analysis and perform analysis expert evaluation(?) present at CSSA conference, November 2013 publish results Next Steps
  21. 21. Web-based map tool for visualizing species distributions and ex situ and in situ gaps National Inventory of CWR of the USA (completed)- need to incorporate into GRIN Gap analysis publication(s) Contribution to new accessions conserved, management plans for conservation of CWR in protected areas Expected Products Helianthus exilis source: Greg Baute
  22. 22. Climate change impacts 2-3 strategic taxa- one sunflower relative, threatened and useful one to two wild cranberries advanced modeling methods- individually chosen environmental variables for book chapter, but in preparation for further work/publications
