RT Journal Article SR Electronic T1 Pacific Northwest Forest Tree Seed Zones JF Native Plants Journal JO NATIVE PLANTS JOURNAL FD University of Wisconsin Press SP 131 OP 140 DO 10.2979/NPJ.2004.5.2.131 VO 5 IS 2 A1 GR Johnson A1 Frank C Sorensen A1 J Bradley St Clair A1 Richard C Cronn YR 2004 UL http://npj.uwpress.org/content/5/2/131.abstract AB Seed movement guidelines for restoration activities are lacking for most native grasses, forbs, and shrubs. The forestry community has decades of experience in establishing seed zones and seed movement guidelines that may be of value to restoration managers. We review the history of seed zone development in forest trees, with emphasis on the Pacific Northwest, and make some suggestions concerning seed transfer guidelines for other native plants.
