Description

Infectious diseases are one of a suite of factors implicated in the declines and extinctions of amphibians worldwide. One such disease, chytridiomycosis, is caused by the chytrid fungus Batrachochytrium dendrobatidis (Bd). Chytrid fungus was discovered in Alberta in 1999 from necropsies of several specimens of boreal toads and northern leopard frogs collected near Caroline. In late 2006, a pilot-study was conducted to determine whether Bd was present at northern leopard frog sites in southern Alberta. The detection of Bd at multiple sites, and in a provincially Threatened species, led to the expansion of Bd surveillance to other areas of the province, and to other amphibian species between 2007 and 2010. The results, reported in this study, provide a base-line for the occurrence and prevalence of Bd in Alberta. This information is required for the effective conservation and management of a broad suite of amphibian species, many of which are of high conservation concern in Alberta.

Description

Field data collection for the Researching Amphibian Numbers in Alberta (RANA) program was initiated in 1997 in response to the global decline of amphibians. RANA has two primary objectives: to collect long-tenn data on amphibian species populations in Alberta, and to provide public education on the importance of amphibians and wetland conservation. This document is a compilation of 2004 field results from the six existing RANA sites at Kananaskis (Bow Valley), Hinton (Athabasca Valley), Lesser Slave Lake Provincial Park, Cypress Hills Provincial Park, Saskatoon Island Provincial Park, and Manook Biological Research Station near Athabasca.
