Heterogeneous vegetation structure can create a variable landscape of predation risk-a "fearscape"-that influences use and selection of habitat by animals. Mapping functional properties of vegetation that influence predation risk (e.g., concealment and visibility) across landscapes can be challenging. Traditional ground-based measures of predation risk are location specific and limited in spatial distribution. We demonstrate the benefits of terrestrial laser scanning (TLS) to map properties of vegetation structure that shape fearscapes. We used TLS data to estimate concealment of prey from multiple vantage points, representing predator sightlines, as well as visibility of potential predators from locations of prey. TLS provides a comprehensive dataset that allows exploration of how habitat changes may impact prey and predators. Together with other remotely sensed imagery, TLS could facilitate scaling up fearscape analyses to promote management and restoration of landscapes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
