First Record of the California Yellow-legged Frog in Park
By W. S. Vincent, Ranger-Naturalist
A small frog which proved to be Rana boylii boylii was collected by the writer in the pond of a small spring on Red Blanket Creek on July 2 while on a field trip with the Park Naturalist George C. Ruhle.
This frog has not been reported previously in any literature as having been collected within the park boundaries. Its range has been reported as being the middle Rogue River valley (vicinity of Medford) and in the area around Lake-of-the-Woods. It has further been reported to the north in Marion, Lane, and Linn counties. This specimen would appear to consolidate these ranges. No further collecting in the area was possible to extend the range within the park.
A brief description of the frog is as follows*: “Light grayish, greenish or brownish back, indistinctly mottled; under parts white to pale yellow on posterior parts and underside of legs; throat and sides of body mottled with dark color; three inches or less in head-body length.”
