Population restoration reinforcement is the release of individuals into an area with the species' historical range and into an area with an existing population of conspecifics The three main issues to consider when considering a release site are suitability of the release site, carrying capacity, species interactions, and socioeconomic acceptability. Mesopredator release an effect that takes place when the larger apex predators of an area are eradicated or are an exotic species and the medium size predators whose populations were suppressed by the larger species, grows Competitive release is when large eradication events, natural or man-driven, causes the boom in populations of other species Chemical pest control can have detrimental effects on an ecosystem through biomagnification, where the concentration of chemicals in the tissues of organisms increases at higher trophic levels Negative impacts from the introduction of non-native species can happen at the ecosystem, community, species, and Population level Sanitation - Benefit: Area will be cleaner and the pest species will not be attracted to the area (bear proof trash) - Cost: More expensive to create containers that keep out the pest animal, there is a cost associated with cleaning. Physical - Benefit: Prevents the pest species from physically effecting an area through traps or other physical deterrents. - Cost: These devices must be manufactured and kept track of. Traps must be monitored. The physical effect can impact non pest species. Biological - Benefit: The pest species population can be reduced to manageable levels by natural means - Cost: there could be unexpected interactions with the species brought to control the pest with the surrounding environment. Chemical - Benefit: Kills the species and protects the crops or infrastructure that could be damaged. - Cost: Has the potential to affect other species and build up within the food chain.
