Scent Deterrence To Reduce Southern Flying Squirrel Kleptoparasitism Of Red-Cockaded Woodpecker Cavities, Jonathon M. Stober, L. Mike Conner Jan 2007

Scent Deterrence To Reduce Southern Flying Squirrel Kleptoparasitism Of Red-Cockaded Woodpecker Cavities, Jonathon M. Stober, L. Mike Conner

Human–Wildlife Interactions

When establishing new populations of endangered red-cockaded woodpeckers (RCW; Picoides borealis), cavity kleptoparasites can pose a considerable obstacle to successful restoration. Southern flying squirrels (SFS; Glaucomys volans) are the principal kleptoparasite of RCW roost and nest cavities. Managers restoring RCW populations primarily use labor-intensive, direct removal to mitigate cavity competition by SFS. We fi eld tested the use of red fox (Vulpes vulpes) urine and rat snake (Elaphe spp.) musk as predator scents to examine if SFS could be deterred from using RCW cavities and to observe RCW roost behavior at cavities treated with red …

Efficacy Of Cpth-Treated Egg Baits For Removing Ravens, Peter S. Coates, Jack O. Spencer Jr., David J. Delehanty Jan 2007

Efficacy Of Cpth-Treated Egg Baits For Removing Ravens, Peter S. Coates, Jack O. Spencer Jr., David J. Delehanty

Human–Wildlife Interactions

Human-altered landscapes have provided resource subsidies for common ravens (Corvus corax) resulting in a substantial increase in raven abundance and distribution throughout the United States and Canada in the past 25 years. Ravens are effective predators of eggs and young of ground-nesting birds. During 2002–2005, we tested whether chicken egg baits treated with CPTH (3-chloro-p-toluidine hydrochloride) could be used to manage raven numbers in an area where raven depredation was impacting sharp-tailed grouse (Tympanuchus phasianellus columbianus) and greater sage-grouse (Centrocercus urophasianus) populations in Nevada. We performed multiple raven surveys at a treatment site and …


Comparison Of Sampling Strategies To Estimate Abundance Of Double-Crested Cormorants In Western Mississippi, Aaron T. Pearse, Brian S. Dorr, Stephen J. Dinsmore, Richard M. Kaminski Jan 2007

Comparison Of Sampling Strategies To Estimate Abundance Of Double-Crested Cormorants In Western Mississippi, Aaron T. Pearse, Brian S. Dorr, Stephen J. Dinsmore, Richard M. Kaminski

Human–Wildlife Interactions

We compared 2 sampling strategies designed to estimate abundance of double-crested cormorants (Phalacrocorax auritus, hereafter cormorants) on aquaculture ponds in western Mississippi. Cormorants are a major predator of cultured channel catfish (Ictalurus punctatus) in this region; thus, estimating cormorant abundance is needed to better determine their economic impact. We independently designed a species-specific survey (i.e., cluster sampling) and a general survey (i.e., transect sampling) based on robust probability sampling theory to estimate abundance of this target population. During winters 2002–2003 and 2003–2004, we conducted 8 pairs of surveys and compared estimates of cormorant abundance and associated …


A Landscape-Level Survey Of Feral Hog Impacts To Natural Resources Of The Big Thicket National Preserve, Pedro M. Chavarria, Roel R. Lopez, Gillian Bowser, Nova J. Silvy Jan 2007

A Landscape-Level Survey Of Feral Hog Impacts To Natural Resources Of The Big Thicket National Preserve, Pedro M. Chavarria, Roel R. Lopez, Gillian Bowser, Nova J. Silvy

Human–Wildlife Interactions

We conducted a survey of the impact of feral hog (Sus scrofa) on the natural resources of the Big Thicket National Preserve (BTNP), a unit of the National Park Service. We worked in 3 management units: Lance Rosier, Big Sandy, and Turkey Creek. Random stratified sampling was conducted to assess impacts from hog damage on resources by vegetation type at a landscape scale. Landscape features such as topography, soil moisture, soil type, and dominant vegetative cover types were used to predict hog damage. The overall damage to vegetation from hog rooting or wallowing averaged 28% within the 3 …

Feral Hog Research In Western Louisiana: Expanding Populations And Unforeseen Consequences, Michael D. Kaller, James D. Hudson Iii, Eric C. Achberger, William E. Kelso Jan 2007

Feral Hog Research In Western Louisiana: Expanding Populations And Unforeseen Consequences, Michael D. Kaller, James D. Hudson Iii, Eric C. Achberger, William E. Kelso

Human–Wildlife Interactions

Hunter harvest data suggest that feral hog (Sus scrofa) populations in western Louisiana are increasing, and population control in this region is complicated by the mixing of feral and domestic free-ranged hogs. Aggressive management may be warranted as feral and domestic hogs appear to be having unexpected effects on their ecosystem. We present the results of 3 recent investigations of genetic source-tracking to link waterborne bacteria with bacteria from feral hogs. We integrate our most recent findings with data regarding: (1) water quality in a watershed without hog management and (2) aquatic biota of the same watershed. Hog …
