Description

This wildlife status report looks at the whooping crane, North America's tallest bird. Whooping crane numbers are stable and slowly increasing due to the results of a number of conservation efforts to restore the species after it reached a global population low of fewer than two dozen individuals. The only self-sustaining migratory flock of whooping cranes numbers about 180 individuals and nests in Wood Buffalo National Park along the border between Alberta and the Northwest Territories. The whooping crane is currently ranked as At Risk in Alberta. The Alberta Wildlife Act also lists the whooping crane as Endangered. The purpose of this status report is to compile and summarize both historic and up-to-date information and to update the current status of the whooping crane in Alberta. It is part of the Alberta Wildlife Status Report series, which provides comprehensive summaries of selected wildlife species intended to be useful to those managing populations of species and their...

Description

During the summer months of 2000 odonate surveys were carried out for the Marguerite Crag and Tail, Maybelle River, and Richardson River Dunes Wildland Provincial Parks, located near the southeast corner of Wood Buffalo National Park. An intensive survey (looking primarily for odonates) occurred from June 11th until June 21st, 2000, while a passive survey (primarily looking for lepidopterians with incidental collections of odonates) occurred from August 20th to August 24th, 2000. The surveys resulted in detecting the presence of 19 dragonfly species (12 in the spring, 7 in the late summer). Five significant records were established (those for Libellula julia, Aeshna subartica, Aeshna canadensis, Calopteryx aequabilis, and Leucorrhinia glacialis) dramatically extending those ranges and significantly contributing to the lack of current data on these species in Alberta. Recommendations include the need for odonate surveys later in the summer, and for protection of the fragile aquatic...
