A Conceptual Interference Competition Model for Introduced Mountain Goats

Description
Summary:I addressed whether competition was likely to occur between sympatric mountain sheep (Ovis canadensis canadensis) and introduced mountain goats (Oreamnos americanus). I examined direct interactions between mountain sheep and mountain goats during a study of habitat selection and activity patterns for the species from 1981 through 1986. I observed 107 interference interactions; 39 (36.5%) resulted in apparent deterrence of sheep from some resource. I applied these data to a conceptual model of interference competition derived from information from other studies and competition theory. The 39 interactions provided an approximate point on a negative effects continuum where negative effects are greater for 1 species than for the other. Introduced or re-introduced wild ungulates potentially raise management challenges if their populations continue to increase and their distributions expand.
