Mammal Surveys of the Lower Arroyo Seco Park, Pasadena, California and of Millard Canyon, Altadena, California
This paper presents the results of a mammal inventon." of the Lower -Ajtovo Seco Park, Pasadena, California and of a similar but less disturbed com- parison site. Millard Canyon, -AJtadena. California. Results indicated that in com- parison the Lower .Ajtovo Seco Park has v,ithin a few decades experienced a moderate loss of mammal species rabbit size and larger and a severe loss of smaller species. Local species extinctions are attributed mainly to the loss of plant as- sociations required by habitat- specific species for foraging and shelter, and sec- ondarily to possible interspecific competition of mouse sized mammals v,ith pock- et gophers.
