The Ecological Monitoring and Assessment Network has released this 1998 publication entitled "Assessment of species diversity in the Montane Cordillera Ecozone." Extending from the eastern Rocky Mountains in Alberta to the western slope of the Cascades in British Columbia, the Montane Cordillera Ecozone is Canada's sixth largest ecozone, covering "more than 49 million hectares." Diverse in topography and climate, the ecozone's landscape ranges "from alpine tundra to dense coniferous forests, grasslands, riparian woodlands, dry sagebrush and Canada's only true desert." The report covers environmental history, habitat types, and human use of the area, in addition to emphasizing species diversity (namely insects, mammals, fish, plants, fungi, birds, and amphibians and reptiles).
