State wildlife agencies have regulatory authority and oversight over deer (Cervidae) management in the United States. However, increased urban sprawl and overabundant deer populations have created increased human–deer conflicts. Because of the growing controversy surrounding the use of traditional management practices such as regulated hunting in suburban areas in the eastern United States, managers are now using specialized tools and management approaches to reduce deer conflicts in urban areas. However, this has created new challenges as they try to meet the desires of diverse stakeholder groups. Although deer management programs in urban areas differ somewhat in every state, effective management options remain limited. Essentially the same management tools that were used for 3 decades have not changed, even with substantial investments in deer research. Despite public support for deer fertility control, it is still largely experimental and expensive. Immunocontraceptive vaccines are seldom used because of the cost and difficulty of retreating free-ranging deer. Surgical sterilization of deer has shown promise, but the scale of application remains limited by cost and the number of deer that need to be handled. Lethal deer removal remains the only method that has consistently reduced deer numbers in an acceptable time frame at multiple scales. Even in areas where urban deer numbers have been substantially reduced using lethal methods, the resulting effects on deer populations and human–deer conflicts have been poorly documented. In highly fragmented, developed landscapes, removing enough deer to demonstrate impact reduction has been a difficult and expensive process. It usually takes multiple approaches across several years to achieve desired results. Thus, the lack of longterm planning and sufficient budgets needed to sustain management efforts may impede overall program success and sustainability. Herein, I review the lessons learned from multiple deer research and management efforts from suburban areas in the eastern United States and highlight potential directions for future urban deer management programs.

: Vultures (Cathartidae and Accipitridae) play an important role in ecosystem balance by rapidly disposing animal carcasses and thus preventing the potential spread of pathogens. Blood chemistry values provide a means of assessing the health of wildlife and wild animal populations; however, there are significant differences in chemistries among species and when comparing captive and free-living New and Old World vultures. In 2007, we collected blood serum from 30 female and 14 male wild, healthy black vultures ( Coragyps atratus ) live-trapped by the U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Wildlife Services from a power substation in Lowndes County, Mississippi, USA. We analyzed the blood serum to provide serum chemistry base values for use in clinical pathology. The chemical analytes we measured included sodium, chloride, potassium, carbon dioxide, anion gap, glucose, creatinine, calcium, phosphorus, total protein, albumin, globulin, and aspartate aminotransferase. In general, blood chemistry values of black vultures were similar to those found in New and Old World vultures and raptor species. Average chemistry values for males were lower than females for sodium, chloride, creatinine, calcium, total protein, albumin, and globulin. The serum chemistry values we describe in this paper can be important indicators of avian health by gender for the black vulture. Our study provided important blood chemistry values from a large sample size, which is rarely available in free-ranging black vultures. These values could be used by scientists, veterinary pathologists, wildlife rehabilitation centers, and other researchers for baseline data for wild and free-ranging birds. Furthermore, the use of such parameters in assessing population health may enable conservationists to further research environmental conditions affecting species reproduction and survival.

Radio-collars and other radio-marking devices have been invaluable tools for wildlife managers for >40 years. These marking devices have improved our understanding of wildlife spatial ecology and demographic parameters and provided new data facilitating model development for species conservation and management. Although these tools have been used on virtually all North American ungulates, their deployment on feral horses (Equus ferus caballus) or burros (E. asinus) has been limited. To determine if radio-collars and radio-tags could be safely deployed on feral equids, we conducted a 1-year observational study in 2015 to investigate fit and wear of radio-collars on feral horses and burros kept in pastures/pens at the Bureau of Land Management contracted adoption facility in Pauls Valley, Oklahoma, USA. We assessed the impact of radio-collars and transmitter tags on individual behavior, body condition, and evaluated neck surface for effects. We tested 2 radio-collar shapes (teardrop and oval) and a radio-tag (i.e., avian backpack) braided into the mane and tail of horses. Behavior of mares did not differ between radio-collared (n = 12) and control (uncollared; n = 12) individuals. Despite the small sample size, collared burro jennies (n = 4) spent more time standing than controls (n = 4). Stallions wearing radio-collars (n = 9) fed less, moved less, and stood more than controls (n = 8). During the study, we did not detect injuries to the necks of mares or burro jennies, but stallions developed small sores (that healed while still wearing radio-collars and re-haired within 3 months). Two radio-collars occasionally flipped forward over the ears onto the foreheads of stallions. Although our study confirmed that radio-collars could be safely deployed on captive mares and jennies, stallions proved challenging for a variety of reasons. While our conclusions were optimistic, longer studies will be required to ensure radio-collar safety on free-ranging feral horses and burros.

Increasing global rates of wildlife species extinctions, extirpations, and declines warrant improvements to population monitoring and management approaches. To address regional environmental and wildlife issues, Indigenous communities globally are re-establishing traditional roles as stewards of the land through emerging Indigenous Guardianship Programs (IGPs). By providing the opportunity for community-level participation in monitoring and management, IGPs help foster cohesive solutions for long-term conservation of species while promoting environmental stewardship at the community level. Addressing challenges in monitoring and management of wildlife is especially critical for species that are of cultural and ecological importance at both community and distribution-wide scales. Herein, we describe IGPs in Canada with a focus on moose (Alces alces), an important species to many Indigenous Peoples across the species’ distribution. We outline common Western approaches to moose monitoring applied across Canadian jurisdictions and discuss ways in which weaving Indigenous knowledge systems and information gathered through local participation from Indigenous communities enhances monitoring initiatives at regional levels. We elaborate on a case study on moose monitoring and co-management in the community of Gitanyow in British Columbia, Canada to highlight the value of Guardianship to communities and species conservation in relation to moose. Our study reveals how IGPs and the weaving of Indigenous and Western knowledge systems can contribute to the maintenance of both ecological and cultural integrity to strengthen wildlife monitoring and management under changing global environments.

The brown-headed cowbird (Molothrus ater; cowbird) is unique among North American blackbirds (Icteridae) because it is managed to mitigate the negative effects on endangered songbirds and economic losses in agricultural crops. Cowbird brood parasitism can further affect species that are considered threatened or endangered due to anthropogenic land uses. Historically, cowbirds have often been culled without addressing ultimate causes of songbird population declines. Similar to other North American blackbirds, cowbirds depredate agricultural crops, albeit at a lower rate reported for other blackbird species. Conflicting information exists on the extent of agricultural damage caused by cowbirds and the effectiveness of mitigation measures for application to management. In this paper, we reviewed the progress that has been made in cowbird management from approximately 2005 to 2020 in relation to endangered species. We also reviewed losses to the rice (Oryza sativa) crop attributed to cowbirds and the programs designed to reduce depredation. Of the 4 songbird species in which cowbirds have been managed, both the Kirtland’s warbler (Dendroica kirtlandii) and black-capped vireo (Vireo atricapilla) have been removed from the endangered species list following population increases in response to habitat expansion. Cowbird trapping has ceased for Kirtland’s warbler but continues for the vireo. In contrast, least Bell’s vireo (V. bellii pusillus) and southwestern willow flycatcher (Empidonax traillii extimus) still require cowbird control after modest increases in suitable habitat. Our review of rice depredation by cowbirds revealed models that have been created to determine the number of cowbirds that can be taken to decrease rice loss have been useful but require refinement with new data that incorporate cowbird population changes in the rice growing region, dietary preference studies, and current information on population sex ratios and female cowbird egg laying. Once this information has been gathered, bioenergetic and economic models would increase our understanding of the damage caused by cowbirds.

The Andean bear (Tremarctos ornatus; bear) is endemic to the tropical Andes Mountains of South America. Previous assessments predict that bear populations will decline by >30% in the next 30 years. The species may face the greatest threats within its historical distribution in Colombia where rapid agricultural expansion into natural habitats is increasing human–bear conflicts. Between April 2017 and March 2018, we studied bear feeding behavior on plantain (Musa sapientum) and banana (M. paradisiaca) crops within the Barbas-Bremen protected area in the central mountain range of Colombia to describe the magnitude of crop damage, economic losses, and spatial distribution of feeding sites where human–bear conflicts would most likely occur. We also identified all affected farmers and used structured interviews to determine their attitudes toward the bears and their conservation. We recorded 237 damaged plants and identified 57 bear feeding area locations on 9 farms. Bear damage consisted of bites to the trunk of each plant and consumption of the centers. The damage polygon covered 198 ha, and it was located in the northwestern portion of the protected area. Although we estimated that <1% of the total plantain and banana production in the area was lost due to bear depredation, surveyed farmers expressed negative attitudes toward bears and conservation groups seeking their protection. Our research is the first estimation of the magnitude of crop consumption by bears and social and economic dimensions of damage caused by the species in Colombia. Our research also provides insights on how human–bear conflicts may be mitigated in the study area.

Between April 2017 and March 2018, we studied bear feeding behavior on plantain (Musa sapientum) and banana (M. paradisiaca) crops within the Barbas-Bremen protected area in the central mountain range of Colombia to describe the magnitude of crop damage, economic losses, and spatial distribution of feeding sites where human–bear conflicts would most likely occur. We also identified all affected farmers and used structured interviews to determine their attitudes toward the bears and their conservation. We recorded 237 damaged plants and identified 57 bear feeding area locations on 9 farms. Bear damage consisted of bites to the trunk of each plant and consumption of the centers. The damage polygon covered 198 ha, and it was located in the northwestern portion of the protected area. Although we estimated that <1% of the total plantain and banana production in the area was lost due to bear depredation, surveyed farmers expressed negative attitudes toward bears and conservation groups seeking their protection. Our research is the first estimation of the magnitude of crop consumption by bears and social and economic dimensions of damage caused by the species in Colombia. Our research also provides insights on how human–bear conflicts may be mitigated in the study area.","PeriodicalId":13095,"journal":{"name":"Human–Wildlife Interactions","volume":"73 1","pages":"10"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84335969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

: The bearded vulture ( Gypaetus barbatus ) is listed as vulnerable in Europe on the International Union for Conservation of Nature Red List because of population declines over multiple generations. Vulture population declines have been attributed to shooting, use of toxicants, and changes in land use, which have resulted in habitat degradation and increased anthropogenic disturbances. Concomitantly, conservation authorities have restricted practices deemed harmful to the species and have established protection buffers around occupied vulture breeding sites to mitigate the impacts of anthropogenic disturbances on breeding success. Comor et al. (2019) compared bearded vulture breeding success over 6 years within and outside areas with restricted activities in the western French Pyrenees and assessed distances between vultures and hunting parties. They concluded that hunting was not a threat to species conservation and may even benefit vultures by providing alternative food resource. We dispute the conclusions of Comor et al. (2019) and present concerns about the data used, the study design, and the inferences taken from some of the data presented. Herein we provide arguments and rationale to support our opinion.
