Approach
In some instances, vulnerable species are able to successfully reproduce and raise juveniles in the wild, as long as natural predation is reduced (Berton C. Harris et al. 2012, Bradley and Neufeld 2012). Managers may opt to reduce predation by physically removing or deterring predators.
Tactics
- Trap and remove nest predators in turtle recovery areas.
- Install predator guards on nest boxes to protect eggs and juveniles from owls, raccoons, cats, and snakes.
- Reduce populations of feral cats to protect songbird populations.
- Trap and relocate fishers out of areas where pine marten populations are struggling to establish.
Strategy Text
Wildlife managers are often concerned with adjusting the population size of vulnerable wildlife species. Managers can affect population size through actions that influence reproduction, survival, and dispersal. This Strategy contains Approaches for increasing populations of vulnerable species, whether they are declining, rare, or have specific climate-related vulnerabilities.
