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.

Description

The information presented in this report represents the findings from the second year of surveying western and eared grebes within the Stony Plain study area in Alberta. The surveys are projected to span a five year period and the project is designed to monitor population trends and reproductive success of western grebes and eared grebes within the Stony Plain study area. In 2004, surveying effort was focused on the primary western and eared grebe populations identified in the previous years of this project. Ground nest surveys were conducted after the nesting period, the results of which were used to derive a total breeding adult population estimate. In addition, surveys were initiated in the Parkland region in 2004, to identify waterbodies that supported potential western grebe breeding colonies.

Description

This project focused on western grebes and eared grebes inhabiting the Stony Plain area, which is within the Parkland and Boreal natural regions of central Alberta. These grebe species have a wide distribution across western and central North America, yet indications are that they may be declining and could become threatened over the long-term. Relatively little research and monitoring attention has been directed toward these species. To address some of these concerns, surveys were conducted to locate grebe colonies, estimate population sizes, and assess their reproductive success. Various survey methods were also developed, tested, and evaluated, thereby providing a framework for future surveys. In doing so, trend data can now be gathered for western and eared grebes, which will enable local and regional status assessment. Management implications are also provided in this report.
