Economy The main industries in the taiga shield are tourism, mining, oil and hunting. Wildlife There are about fifty different species of mammals, including the Northern Red-Backed Vole

Migration in the spring brings multiple species, like the Willow Ptarmigan

Only amphibians, including the Blue-Spotted Salamander, live in the taiga shield
Vegetation Trees iclude black spruce, jack pine, willow, tamarack, and paper birch

Lots of ferns, mosses, and small plants such as kinnikinick and bearberry.
Landforms Mostly either flat or rolling hills; also, advancing/retreating glaciers have created several depressions in the landscape that have become lakes.

Most of the area has become either teporarily or permanently waterlogged. Enviromental Issue Article Population trends for over half of Canadian shorebirds are negative. Out of the 28 Northwest Territories / Nunavut-nesting species that were analysed, 26 show persistent, negative trends. Loss or contamination of breeding or staging habitat, together with increased access by humans to large areas of the North, is the source of the greatest impacts to migratory birds from development.. Some developments effects are cross-cutting and cumulative, such as ancillary developments (roads) from forestry operations and an oil and gas project in the same area. Generally, the geographic regions where impacts will be greatest over the next ten years are the southwestern Northwest Territories (NWT), the Slave Geological Province/West Kitikmeot mining clusters, and the Mackenzie Delta and Beaufort Sea region.
