166 DEPREDATION TRENDS IN CALIFORNIA SARAH REED, Mountain Lion Foundation, PO Box 1896, Sacramento, CA 95814, USA CHRISTOPHER M. PAPOUCHIS, Mountain Lion Foundation, PO Box 1896, Sacramento, CA 95812, USA, email: cpapouchis@mountainlion.org LYNN MICHELLE CULLENS, Mountain Lion Foundation, PO Box 1896, Sacramento, CA 95812, USA, email: cullens@mountainlion.org Abstract: Since 1972 more than 1,600 California mountain lions have been killed under depredation permits. The number of lions killed annually has increased, with a peak of 149 lions killed in 2000. Although some permits are issued for losses incurred by traditional, economically viable, open range livestock operations, incidents on ranchettes and "hobby farms" are increasing. We evaluate trends in depredation permitting, including analysis of depredation events geographically, by parcel size and size of herd, and relative to human population and development trends. We conclude with new approaches to mountain lion conservation that stress science to establish a factual basis for dialogue, community involvement, and developing partnerships with diverse stakeholders.

THE DISTRIBUTION OF PERCEIVED ENCOUNTERS WITH NON-NATIVE CATS IN SOUTH AND WEST WALES, UK: RELATIONSHIP TO MODELED HABITAT SUITABILITY A.B. SMITH, Exotic Cat Group, Geography Department, University of Wales Swansea, Singleton Park, Swansea SA2 8PP, UK, email: exoticcatproject@swan.ac.uk F.A. STREET PERROTT, Exotic Cat Group, Geography Department, University of Wales Swansea, Singleton Park, Swansea SA2 8PP, UK T. HOOPER, Exotic Animals Register, 85 Risedale Road, Ashton Vale, Bristol BS3 2RB, UK Abstract: Reports of perceived encounters with exotic cats in the British countryside have greatly increased in recent years. The species described (notably melanistic leopards, pumas and lynxes) were widely bred in the UK prior to the 1976 Dangerous Wild Animals Act, and do not correspond to those most familiar to the general public (such as lions, tigers and cheetahs). Some of them are still being illegally imported or reared for ‘canned hunts’. Following the recent discovery of leopard tracks in West Wales, and calls for action by Members of the UK Parliament and the Welsh National Assembly, the Welsh Agriculture Department has officially begun to collect statistics on sightings and livestock kills. In this independent study, we have analysed a database of 170 georeferenced encounter reports obtained from the police, news media and members of the public. In the absence of confirmatory DNA, physical or photographic evidence, encounter reports require very careful screening for reliability, based on the characteristics of the witness(es); the validity of the identification, taking into account perceived cat size and shape (morphotype) and behaviour; indicators of scale, distance and lighting conditions; and the suitability of the habitat. The distributions of potential habitats within South and West Wales have been modelled with a GIS using standard habitat characteristics, such as prey-species presence, disturbance levels, geomorphology and land-use data. The spatial pattern of encounters does not show the clustering that might be expected if they represent a purely sociological phenomenon. Instead, the distributions of specific morphotypes appear to be closely related to the degree of habitat suitability, thereby strengthening the case for the presence of nonnative cat species in the UK.
