Conservation Strategies For Protecting Tiger Beetles And Their Habitats In The United States: Studies With Listed Species (Coleoptera: Carabidae: Cicindelidae)
ANNALS OF THE ENTOMOLOGICAL SOCIETY OF AMERICA(2021)
Abstract
Tiger beetles are a popular, widely studied group of charismatic insects that are a flagship taxon for insect conservation. Five species are currently listed in the United States as Federally Endangered or Threatened, two others have recently been delisted, and many more are listed by individual states. To date, the status of some of these species has been improved or their decline slowed by various conservation strategies. In this article, we review the background and the recent conservation activities for all federally listed tiger beetle species. These species have lost much of their historic habitat and remain at risk because of continuing impacts from vegetation encroachment of native or invasive plants, water-level changes, and other human-related activities. Conservation efforts are limited because for most species there is little or no potential habitat remaining, even following restoration activities. Effective strategies have included long-term monitoring of population size and research activities, acquisition and protection of occupied sites, methods for controlling vegetation encroachment to improve habitat quality, and recent efforts with translocations using beetles from existing populations or from captive rearing. Because tiger beetle life histories are similar, successful management and research methods for any one species can be applicable to others. This presents an opportunity to coordinate taxon-level conservation for all U.S. species through cataloged information and conservation leadership
