The Above-Ground Movement And Dispersal Of The Plains Pocket Gopher (Geomys Bursarius), Craig Panich
The Above-Ground Movement And Dispersal Of The Plains Pocket Gopher (Geomys Bursarius), Craig Panich
11th Triennial National Wildlife and Fisheries Extension Specialists Conference (2006)
The Plains pocket gopher has the largest range of its genus, and it is the gopher that inhabits much of Wisconsin. Gophers are fossorial herbivores that have a dramatic impact on natural and agricultural ecosystems. Throughout the summer of 2005, I completed a population analysis of the plains pocket gopher in a variety of habitats in Buffalo and Trempealeau Counties, Wisconsin, that provided valuable insight into the complex population dynamics of the gopher and served as a foundation to this project. Pocket gophers are known to be strictly subterranean; however, it is not uncommon to find their remains inside the …
The Bait Surcharge Program: Research Improves Zinc Phosphide Use For Vole Control In Alfalfa, Ray T. Sterner
The Bait Surcharge Program: Research Improves Zinc Phosphide Use For Vole Control In Alfalfa, Ray T. Sterner
Proceedings of the Eighteenth Vertebrate Pest Conference (1998)
This paper describes several unexpected benefits of rodenticide-registration research funded by The California Bait Surcharge Program. An enclosure-type study was conducted to determine efficacy of single, pre- and test-bait broadcasts (10 lb./ac.) of 0% and 2% zinc phosphide (Zn3P2, CAS #1314-84-7) steam-rolled-oat (SRO) groats to control voles (Microtus spp.) in alfalfa (Medicago sariva). Unexpected research spinoffs resulted from the use of: 1) eight randomly-located, sieved-dirt plots per enclosure to monitor bait distribution, bait removal, and rodent/avian (non-target) activity; 2) a bait-weathering plot and bait-sample analyses to monitor Zn3P2 biodeterioration; and …
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
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.
