Cultural Control Of Damage To Alfalfa Caused By Pocket Gophers, Ronald M. Case, Debra Baker, James Luchsinger, Bruce Jasch
Cultural Control Of Damage To Alfalfa Caused By Pocket Gophers, Ronald M. Case, Debra Baker, James Luchsinger, Bruce Jasch
Great Plains Wildlife Damage Control Workshop Proceedings
In 1989 we postulated that using different varieties of alfalfa might minimize damages caused by pocket gophers (Geomys spp.). We tested a tap-rooted variety (Wrangler) and a fibrous-rooted variety (Spredor 2). From previous studies, Wrangler out performs Spredor 2 by as much as 27% by the fourth year after planting. Spredor 2, however, has a creeping habit and it sends up new shoots on lateral roots. When a root breaks, it sends up new shoots. Therefore, we predicted that Spredor 2 would be damaged less by below-ground foraging by plains pocket gophers (G. Bursarius). Additionally, Spredor 2 …

Effects Of Mule Deer Grazing On Alfalfa Seed Production, Dennis D. Austin, Philip J. Urness
Great Plains Wildlife Damage Control Workshop Proceedings
Evaluation of crop loss caused by mule deer (Odocoileus hemionus) grazing on alfalfa grown for seed harvest was studied in northern Utah. Results indicated (1) wire baskets used to protect non-grazed plots did not affect alfalfa production, and (2) alfalfa seed crop loss was directly correlated with alfalfa hay crop loss. Consequently, methods used to evaluate crop loss to alfalfa hay may be applied to alfalfa seed.
