Northern Leopard
Frog
Northern Leopard Frog
(Rana pipiens)
Research Objectives:
-
To determine the extent of the
remaining Northern Leopard Frog population and the
Creston Valley population in particular.
-
To make recommendations for
the species survival in B.C. from these findings.
Preliminary Findings:
-
The Creston Valley population
appears to be more aquatic than some of the eastern populations.
The eastern populations travel as much as .5 km to favored breeding,
feeding or hibernaculum's while the Creston population travels
very little- almost all activities are contained within the
same marsh habitat.
-
Permanent, slow moving or still
water with solid shorelines and an abundance of cat-tail and
other long stemmed marsh grasses were found in and on the borders
of the only productive marsh in the Creston Valley.
-
Winter habitat requirements
for hibernation appear to be deep enough water so that water
near the pond bottom does not freeze. The pond bottom must have
cover in the form of permanent vegetation and be soft enough
for the frogs to be able to excavate a shallow cavity to retreat
in.
-
Approximately two hundred individual
adults and juveniles have been found in the Creston Valley.
-
Recommendations to move some
of the Creston juveniles to former breeding sites in B.C.
are being considered.
