The county population of red-legged partridge is sustained by annual releases for the purpose of shooting. Those birds which survive the shooting season are able to breed but it is doubtful that a self sustaining population would endure without further releases. Comparing the results of the two surveys indicates a fivefold increase but in the absence of information on the scale of releases, which appears to be unregulated, it is impossible to meaningfully interpret these findings.
