Description

We present an easily accessible database of interpolated climate data for Alberta that includes monthly, annual, decadal and 30-year normal climate data for the last 106 years (1901-2006), as well as climate change projections for the 21st century from 23 general circulation models. The database builds on the Alberta Climate Model and a set of five future projections that are recommended and widely used by Alberta government agencies. We added 15,000 historical and projected climate surfaces that include variables relevant for biological research and infrastructure planning, such as growing and chilling degree days, heating and cooling degree days, growing season length descriptors, frost free days and extreme minimum temperature. The database can be queried through a provided software package ClimateAB. A representative subset of these climate surfaces has been thoroughly checked against observed weather station data. We report error estimate for historical climate data and discuss...

Description

As part of ongoing grizzly bear management and recovery efforts in Alberta, the Department of Sustainable Resource Development has been annually conducting population estimates in bear management units along the eastern slopes of Alberta since 2004. In 2003, a detailed analysis of genetic samples from grizzly bears, collected over a 22-year period, was conducted to delineate genetically distinct population units. This analysis showed that previous population unit boundaries did not fully match genetic population units and therefore recommendations were made to modify the management unit boundaries at that time.

Description

The Alberta Recovery Plan for Ord's kangaroo rat calls for standardized population monitoring as a highly priority recovery activity. The purpose is to establish a long-term database that supports defensible, inter-annual comparisons of distribution, relative abundance, and survival, including: i) evaluation of population-persistence and rates of extinction and re-colonization of local populations; ii) quantification of variation and trends in relative abundance; and iii) estimation of annual survivorship. These measures will be used to direct management activities and to evaluate the relative success of the recovery of this species. This document provides a detailed population monitoring protocol to serve as a guide for implementation of long-term, standardized monitoring for the Ord's kangaroo rat in Alberta.

Peregrine falcon surveys and monitoring in the northeast Boreal region of Alberta, 2001

Description

Due to the widespread use and environmental accumulation of pesticide residues, the peregrine falcon population declined throughout North America during the 1950s and 1960s. Populations of the falcon improved following the ban of DDT in Canada in 1969 and efforts to protect the species. As a result of the population increase, the species was down-listed to Threatened in Alberta in 2000. Throughout the decline and subsequent recovery of peregrines in Alberta, annual monitoring has been an integral component of managing this species. In 2001, it was agreed that annual occupancy and productivity monitoring in three study areas of northern Alberta would be conducted. This report presents results from surveys in the Fort Chipewyan and Edmonton area during the summer of 2001.

Recommendations for the management of competitive fishing in Alberta

Description

The disparity of fishing pressure and available resource has prompted concerns regarding the impacts of competitive fishing events on fish resources and traditional sportfishing. These events tend to attract more anglers to the water bodies where they are held than might otherwise visit and a large portion of the total annual harvest of some species can be taken in just a few days. Although many events adopted a catch and release format to address the issue of increased fishing pressure, studies conducted in Alberta have shown that fish survival can be very low, and few competitive fishing events have total fish mortalities below 10%. Increased survival rates of released fish can be achieved by regulating where, when and how events are run, by instituting best management practices and by educating anglers on proper fish handling techniques.

Description

The lake sturgeon is a unique component of Alberta's wildlife and a prized sportfish. In Alberta, lake sturgeon are now confined to two areas: the North Saskatchewan and South Saskatchewan river systems. This project assessed the management utility of existing harvest data on species populations by means of a creel survey on the South Saskatchewan River conducted in the summer of 2000. The survey data were compared to data collected from an annual questionnaire sent to all holders of a sturgeon fishing licence.

Description

Forest company forest management plans (FMPs) detail when, where and how timber on Alberta Crown land will be managed in order to balance social, economic and environmental needs based on input from the public, Indigenous peoples and interest groups. The forest management planning area under consideration is FMA 9700033. The FMP includes the Forest Management Agreement and non-FMA portion of FMU S19, collectively known as the Defined Forest Area (DFA). The DFA is located in north central Alberta within the Upper Athabasca, Upper Peace and Lower Peace Land-Use Framework planning regions. The DFA falls within the Central Mixedwood and Dry Mixedwood natural subregions.

Description

Western spiderwort is listed as Threatened nationally and has been recommended for Endangered status provincially. In 2004, the Alberta Western Spiderwort Recovery Team created a maintenance and recovery plan for western spiderwort in Alberta. In addition to identifying several knowledge gaps in various aspects of biology of the species, the plan calls for an annual population inventory of western spiderwort. The objective of this study was to complete a population inventory for the year 2005 using a method that could be repeated in future studies. Limited information on habitat requirements was also provided.
