The Provincial Northern Leopard Frog Recovery Team (NLFRT), comprised of members from the Ministry of Forests, Lands, and Natural Resource Operations, the Creston Valley Wildlife Management Area, and private consultants, is soliciting Duck Lake users’ help to protect and recover the northern leopard frog by avoiding driving motorized vehicles on the dikes around Duck Lake from September 1st to October 15th, between 6:00 PM and 6:00 AM.
The Creston Valley is home to the last population of leopard frogs in British Columbia and is one of the most endangered species of wildlife in the province. In the fall, the leopard frog moves from its breeding and summer grounds to overwintering habitat and requires crossing the dikes south of Duck Lake. The frog migration is highly dependent on weather conditions and can occur from late August to late October but generally peaks during the month of September, and mostly takes place between dusk and dawn. The frogs not only cross the dikes to get to the overwintering habitat, but they also use the warm gravelly surface to forage around; this makes them extremely vulnerable to being run over by motorized vehicles.
The NLFRT has been collecting mortality data over several years and feels it is critical to get the public’s cooperation, drivers in particular, to provide the leopard frogs with a safe migration during this critical period. The NLFRT is calling for a “voluntary” vehicle road closure between 6:00 PM and 6:00 AM from September 1st to October 15th along the dikes (highlighted in red on the attached map.)
