Objective

This project aims to advance our understanding of the factors associated with the survival of rehabilitated wildlife, through quantifying the effects of the rehabilitation process on post-release survival.

Rationale

Considerable time and resources are put into wildlife rehabilitation in Britain: there are over 700 rehabilitation centres treating approximately 40 000 wildlife casualties a year. Yet much of the current advice on release protocols is based on intuitive rather than quantified assessments. Animal welfare standards may be improved if we can quantify the impact of different levels of treatment/ lengths of care etc on the chances of survival.

Wildlife rehabilitation is also used internationally as a conservation tool under the banner of 'restoration ecology', a discipline that is rapidly growing (other conservation tools under this banner include captive breeding, translocation and reintroduction). The more we understand about which species or taxa do well in rehabilitation, the closer we are to understanding some of the underlying principles of restoration ecology, and the basic problems associated with saving species using this method.
