Context of Given
In addition to breeding genetically appropriate animals, the recovery site itself needs to be ready to receive them. Although the species may have historically thrived in a particular location, its suitability isn’t always a given. The species’ decline is likely linked to ongoing environmental factors, including climate change, invasive species, and diminishing food supply, as well as human factors such as pollution, land development, or persecution. Solving these underlying problems is fundamental to a reintroduction’s success, but takes research, time, and effort.
