Testing Fladry As A Nonlethal Management Tool For Wolves And Coyotes In Michigan, Sarah J. Davidson-Nelson, Thomas M. Gehring Jan 2010

Testing Fladry As A Nonlethal Management Tool For Wolves And Coyotes In Michigan, Sarah J. Davidson-Nelson, Thomas M. Gehring

Human–Wildlife Interactions

Several forms of nonlethal management exist, but fi eld testing is problematic, and few such techniques have been tested on free-ranging wolves (Canis lupus) or other predators. We tested fladry in the eastern Upper Peninsula of Michigan during the summers of 2004 and 2005 on treatment farms and control farms. Wolf visitation inside pastures, compared to those outside pastures, was less on fladry-protected farms (U = 45, n = 7, P = 0.004); whereas, we found no difference in wolf visitation inside and outside of pastures on control farms (U = 30, n = 7, P …

Bullet Fragmentation And Lead Deposition In White-Tailed Deer And Domestic Sheep, Marrett D. Grund, Louis Cornicelli, Leah T. Carlson, Erika A. Butler Jan 2010

Bullet Fragmentation And Lead Deposition In White-Tailed Deer And Domestic Sheep, Marrett D. Grund, Louis Cornicelli, Leah T. Carlson, Erika A. Butler

Human–Wildlife Interactions

In February 2008, a private physician in North Dakota radiographed hunterharvested venison and found that 60 of 100 packages contained metal fragments. This discovery had implications for public-funded venison donation programs, and it prompted several Midwest states to examine their programs. Approximately 500,000 deer hunters harvest >200,000 deer annually in Minnesota, and the state has a donation program similar to North Dakota’s program. Therefore, we analyzed fragmentation patterns and lead deposition in carcasses of 8 white-tailed deer (Odocoileus virginianus) and 72 domestic sheep (Ovis aries). We fired 5 different bullet types from centerfire rifles, and we …


Improved Methods For Deterring Cliff Swallow Nesting On Highway Structures, Michael Delwiche, Robert W. Coates, W. Paul Gorenzel, Terrell P. Salmon Jan 2010

Improved Methods For Deterring Cliff Swallow Nesting On Highway Structures, Michael Delwiche, Robert W. Coates, W. Paul Gorenzel, Terrell P. Salmon

Human–Wildlife Interactions

Cliff swallows (Petrochelidon pyrrhonota) are migratory birds that frequently nest on highway structures, such as bridges. Because cliff swallows are protected by the Migratory Bird Treaty Act of 1918, nesting control methods must not harm cliff swallows or disturb active nests. This can cause delays for maintenance divisions of state departments of transportation, resulting in additional cost. In a multiyear project, we evaluated the effects of bioacoustic deterrents and bridge surface modifications on nesting behavior of cliff swallows. We used cliff swallow alarm and distress calls as bioacoustic deterrents (hereafter, broadcast calls [BC]) because they previously had been …
