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. Inventory media coverage

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

6. Gap Analysis Methodology
Determine gaps
Model
distributions
Gather taxonomic
data
Gather occurrence
data
Make conservation
recommendations
Georeferencing

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. Occurrence data- global dataset

9. Gap analysis: methodology

11. Gap Analysis: US results for 29 genepools

12. Gap analysis: expert evaluation

13. Occurrence data (P1 genera)

14. Preliminary gaps

15. Preliminary gaps

16. Preliminary gaps

17. Preliminary gaps

18. Preliminary gaps

19. Gap analysis: methodological improvements

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. 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

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
