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:
https://www.crops.org/publications/cs/articles/53/4/1496
Inventory media coverage
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

Gap Analysis Methodology
Determine gapsModel
distributions
Gather taxonomic data
Gather occurrence data
Make conservation recommendations
Georeferencing
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
Occurrence data- global dataset

Gap analysis: methodological improvements
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
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
Climate change impacts
2-3 strategic taxa- one sunflower relative, threatened and usefulone to two wild cranberries
advanced modeling methods-individually chosen environmental variables
for book chapter, but in preparation for further work/publications
