Description

The Alberta Wild Species General Status Listing (GOA 2010) classifies the long-toed salamander (Ambystoma macrodactylum) as Sensitive because the distribution may be declining due to vulnerability to habitat alteration associated with industrial, recreational, and transportation development. This report provides an update on the population trends of long-toed salamanders in the Bow Valley and Kananaskis area.

Description

Declines in amphibian populations at local, regional and global scales have focused attention on this group of vertebrates. Of the 10 amphibian species in Alberta, seven are listed as "at risk" by provincial or federal agencies. In response to concern about amphibians populations, and a lack of amphibian monitoring in the province, the Researching Amphibian Numbers in Alberta (RANA) program was initiated in 1997 with two main objectives: to collect long-term information on amphibian populations, and to increase public awareness of the importance of amphibians and wetland conservation. Seven RANA sites were established in Alberta and monitored using pitfall trapping at a designated poind within each study area. This report presents an analysis of pitfall trapping data collected between 1997 and 2008.

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

The Researching Amphibian Numbers in Alberta (RANA) program was initiated in 1997 in response to the global decline of amphibians and aims to establish long-term amphibian population and distribution data while increasing public awareness of the importance of amphibians and their wetland habitat. This report summarizes results from the 2005 field season of the RANA program and presents amphibian population trends from the history of the program.

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.
