“…Although invasive species are one of the major threats to biodiversity globally, there has been relatively little attention on estimating the effects of invasive species on bats . An exception is the invasive fungal pathogen that causes WNS in North America, a disease that has caused severe mortality among hibernating bats . Welch and Leppanen provide a review of the threat of invasive species on bats and identified 37 invasive species as threats to 40 bat species based on searching the IUCN Red List and the literature.…”

“…reviewed the global conservation status of bats over 15 years ago, habitat loss or modification, roost site loss or disturbance, human health issues, persecution, lack of information, and overexploitation for food were identified as the major threats to bats globally. Many of these issues remain major threats, but in the intervening years, new threats have also emerged, including mass die‐offs of pteropodid bats in Australia and South Asia from heat waves, high rates of mortality at wind energy turbine installations, and the emergence of an infectious fungal disease of bats, white‐nose syndrome (WNS), in North America . The open‐access book Bats in the Anthropocene: Conservation of Bats in a Changing World offers a recent and thorough review of the major conservation issues for bats, revealing the breadth and depth of anthropogenic stressors on bat populations globally…”

Bats are an ecologically and taxonomically diverse group accounting for roughly a fifth of mammalian diversity worldwide. Many of the threats bats face (e.g., habitat loss, bushmeat hunting, and climate change) reflect the conservation challenges of our era. However, compared to other mammals and birds, we know significantly less about the population status of most bat species, which makes prioritizing and planning conservation actions challenging. Over a third of bat species assessed by the International Union for Conservation of Nature (IUCN) are considered threatened or data deficient, and well over half of the species have unknown or decreasing population trends. That equals 988 species, or 80% of bats assessed by IUCN, needing conservation or research attention. Delivering conservation to bat species will require sustained efforts to assess population status and trends and address data deficiencies. Successful bat conservation must integrate research and conservation to identify stressors and their solutions and to test the efficacy of actions to stabilize or increase populations. Global and regional networks that connect researchers, conservation practitioners, and local stakeholders to share knowledge, build capacity, and prioritize and coordinate research and conservation efforts, are vital to ensuring sustainable bat populations worldwide.

“…Bat populations in the eastern United States are currently experiencing precipitous declines due to white-nose syndrome (WNS), a disease that has killed millions of bats since 2006 [36], and additional stressors, including habitat loss and wind energy development [37]. Knowledge and understanding of habitat use by forest bats in relation to local, stand, and landscape characteristics are critical to bat conservation and management.…”

An Incremental Economic Analysis of Establishing Early Successional Habitat for Biodiversity

Early successional habitat (ESH) is an important component of natural landscapes and is crucial to maintaining biodiversity. ESH also impacts endangered species. The extent of forest disturbances resulting in ESH has been diminishing, and foresters have developed timber management regimes using standard silvicultural techniques that enhance ESH. We developed a financial framework to evaluate these ESH-enhancing forest management regimes, driven by differences in timber harvest costs and timber revenue. The economic model was applied to on-the-ground prescriptions in the Nantahala National Forest (NNF) designed to increase biodiversity and foster improved public awareness of the importance of ESH. Bats, a current conservation concern, commonly exploit ESH and were the focus of our prescriptions. The prescriptions were based on shelterwood cuts of varying patch size, spacing between the cuts, and the trail area required to move from patch to patch. The results showed that prescriptions with large patch areas were effective in increasing ESH, with minimal impact on the financial performance of timber harvesting operations. This information can be used to minimize financial losses while catering to wildlife species that prefer ESH, in addition to increasing overall biodiversity.

“…WNS, a disease of hibernating bats caused by the fungus Pseudogymnoascus destructans (Lorch et al, 2011;Minnis & Lindner, 2013), affects multiple hosts and has caused declines in at least seven species of hibernating bats in North America (Frick, Puechmaille, & Willis, 2016). When SDM was first applied to the management of WNS in unaffected hibernacula (Szymanski et al, 2009), the disease had only been documented in the northeastern United States (USA) for2 years and the causative agent was not yet known.…”

Different management strategies are optimal for combating disease in East Texas cave versus culvert hibernating bat populations

Management decisions for species impacted by emerging infectious diseases are challenging when there are uncertainties in the effectiveness of management actions. Wildlife managers must balance trade-offs between mitigating the effects of the disease and the associated consequences on other aspects of the managed system. An example of this challenge is exemplified in the response to white-nose syndrome (WNS), a disease of hibernating bats. The fungal pathogen that causes WNS, Pseudogymnoascus destructans, continues to spread throughout North America. Texas, recently confirmed positive for the fungus, has documented 33 bat species in the state, with nearly half of those species naïve to the pathogen. We explicitly incorporated multiple management objectives, uncertainty, and risk in the Texas Parks and Wildlife Department decision to manage East Texas populations of the tri-colored bat (Perimyotis subflavus), a species highly susceptible to WNS. Alternatives included individual actions that act against P. destructans or benefit bats, a no active management option, and combinations of actions. Although our main objective was to identify WNS mitigation measures for tricolored bats in culverts, we also considered the transferability of the decision for natural caves. In this scenario, the optimal decision differed for culverts and caves, with a "portfolio" combination of actions ranking as the best alternative for culverts and a single vaccine alternative for caves. Because the top management alternatives differed markedly between these two systems, finding treatments that have broad application is likely infeasible, given that each management decision is characterized by different mixtures of competing objectives.
