Large Birds Of Prey, Policies That Alter Food Availability And Air Traffic: A Risky Mix For Human Safety, Rubén Moreno-Opo, Antoni Margalida Dec 2017

Large Birds Of Prey, Policies That Alter Food Availability And Air Traffic: A Risky Mix For Human Safety, Rubén Moreno-Opo, Antoni Margalida

Human–Wildlife Interactions

Raptors are considered to pose one of the greatest aviation bird strike risk. We investigated raptor bird strikes reported at the largest Spanish airport (Adolfo Suárez Madrid Barajas; AS-MB) from 2009 to 2016 to determine the factors contributing to the increased incidences and develop recommendations to mitigate the risks. We hypothesized that increased raptor bird strikes resulted from changes in foraging and dispersal patterns of Iberian Peninsula vultures (Aegypius spp. and Gyps spp.) after 2004-2005. We used information on raptor bird strikes obtained from official databases and published studies, reported incidences of raptor bird strikes and their characteristics (i.e., …


Learning To Live With Wolves: Community-Based Conservation In The Blackfoot Valley Of Montana, Seth M. Wilson, Elizabeth H. Bradley, Gregory A. Neudecker Dec 2017

Learning To Live With Wolves: Community-Based Conservation In The Blackfoot Valley Of Montana, Seth M. Wilson, Elizabeth H. Bradley, Gregory A. Neudecker

Human–Wildlife Interactions

We built on the existing capacity of a nongovernmental organization called the Blackfoot Challenge to proactively address wolf (Canis lupus)-livestock conflicts in the Blackfoot Valley of Montana. Beginning in 2007, wolves started rapidly recolonizing the valley, raising concerns among livestock producers. We built on an existing program to mitigate conflicts associated with an expanding grizzly bear population and worked within the community to build a similar program to reduce wolf conflicts using an integrative, multi-method approach. Efforts to engage the community included one-on-one meetings, workshops, field tours, and regular group meetings as well as opportunities to participate in …


Use Of Soil Chemical Analysis To Detect Commercial Wildlife Game Baits, Aaron Haines, Angela Fetterolf, Meta Griffin, Tristan Conrad, Steven Kennedy Sep 2017

Use Of Soil Chemical Analysis To Detect Commercial Wildlife Game Baits, Aaron Haines, Angela Fetterolf, Meta Griffin, Tristan Conrad, Steven Kennedy

Human–Wildlife Interactions

Hunters and poachers often use commercially-available, nutrient-rich baits to attract wildlife game animals. We used atomic absorption spectroscopy and ion selective electrochemical analysis techniques to determine whether two common proprietary baits (Deer Cane and Acorn Rage) would leave detectable chemical signatures in soil (i.e., Na+, Cl-, and Ca+2). Our goal was to evaluate low cost tests which could be replicated by wildlife conservation officers in the field. To complete the evaluation we randomly placed two commercial baits on 3 sites in The Millersville University Biological Preserve in Millersville, PA. We collected soils samples from …


Humans As Prey: Coping With Large Carnivore Attacks Using A Predator-Prey Interaction Perspective, Vincenzo Penteriani, Giulia Bombieri, José María Fedriani, José Vicente López-Bao, Pedro José Garrote, Luca Francesco Russo, María Del Mar Delgado Sep 2017

Humans As Prey: Coping With Large Carnivore Attacks Using A Predator-Prey Interaction Perspective, Vincenzo Penteriani, Giulia Bombieri, José María Fedriani, José Vicente López-Bao, Pedro José Garrote, Luca Francesco Russo, María Del Mar Delgado

Human–Wildlife Interactions

The number of attacks on humans by large carnivores in North America is increasing. A better understanding the factors triggering such attacks is critical to mitigating the risk of future encounters in landscape where humans and large carnivore co-exist. Since 1955, of the 632 attacks on humans by large carnivores, 106 (17%) involved predation. We draw on concepts and empirical evidence from the Predator-Prey Interaction Theory to provide insights into how to reduce predatory attacks and, thus, improve human-large carnivore co-existence. Because large carnivore-caused mortality risks for humans are comparable to those shown by other mammal species in response to …


Community Perceptions Of Grivet Monkey Crop Depredation In The Ethiopian Highlands: Implications For Primate Conservation, Aschalew Alelign, Meheretu Yonas Sep 2017

Community Perceptions Of Grivet Monkey Crop Depredation In The Ethiopian Highlands: Implications For Primate Conservation, Aschalew Alelign, Meheretu Yonas

Human–Wildlife Interactions

Human–primate conflicts in Africa have been increasing due to increased human population growth and the resulting competition for forest resources. The Ethiopian Highlands in northern Ethiopia, home to the grivet monkey (Chlorocebus aethiops), once consisted of large forested areas. This region has been severely denuded and now exhibits only small forest patches remaining at sites with special cultural significance in the immediate vicinity of churches. These forest patches, surrounded by agricultural crops, provide refugia habitat for the grivet monkey. We randomly surveyed 50 villagers living near the Batiero Church Forest, a 45-ha forest patch located in northern Ethiopia, to determine …


Using Resident-Based Hazing Programs To Reduce Human-Coyote Conflicts In Urban Environments, Mary Ann Bonnell, Stewart W. Breck Sep 2017

Using Resident-Based Hazing Programs To Reduce Human-Coyote Conflicts In Urban Environments, Mary Ann Bonnell, Stewart W. Breck

Human–Wildlife Interactions

Abstract The concept of hazing (aversive conditioning) is often promoted as a tool for reducing human-coyote (Canis latrans) conflicts in urban environments. Little scientific evidence exists on the effectiveness of hazing, particularly hazing applied by residents (i.e., community-level hazing). Wildlife professionals question if residents will properly and consistently apply hazing techniques and if hazing impacts coyote behavior over short- and long-term periods. We describe two separate efforts designed to encourage residents to haze coyotes in the Denver Metro Area; a citizen-science program and an open space hazing trial. Both efforts were intended to be management techniques that either …


Evaluating Lethal And Nonlethal Management Options For Urban Coyotes, Stewart W. Breck, Sharon A. Poessel, Mary Ann Bonnell Sep 2017

Evaluating Lethal And Nonlethal Management Options For Urban Coyotes, Stewart W. Breck, Sharon A. Poessel, Mary Ann Bonnell

Human–Wildlife Interactions

Human-coyote conflict in urban environments is a growing issue in cities throughout the United States with the primary problem being the development of problem individuals that are overly bold and aggressive with people and pets. Little research has focused on management options to deal with this conflict. We better define lethal and nonlethal management strategies associated with proactive and reactive management of coyotes with an emphasis on management of problem individuals. We then provide data from research in the Denver Metropolitan Area (DMA) that focused on reactive lethal removal of problem coyotes and reactive nonlethal hazing (i.e., community-level hazing, a …


Coyote Attacks On Humans, 1970-2015: Implications For Reducing The Risks, Rex O. Baker, Robert M. Timm Sep 2017

Coyote Attacks On Humans, 1970-2015: Implications For Reducing The Risks, Rex O. Baker, Robert M. Timm

Human–Wildlife Interactions

Beginning with the emerging pattern of urban and suburban coyotes (Canis latrans) attacking humans in southern California in the late 1970s, we analyzed information from reported attacks to better understand the factors contributing to changes in coyote behavior. We subsequently used updated data collected largely in urban and suburban environments in the United States and Canada during the past 30 years to develop strategies to reduce the risk of attacks. In the 1990s, increased incidents of coyote attacks were reported in states beyond California and in Canadian provinces. We documented 367 attacks on humans by coyotes from 1977 …
