- Environment Canada. 2007. Recovery Strategy for the Horned Lark strigata subspecies (Eremophila alpestris strigata) with consideration for the Vesper Sparrow affinis subspecies (Pooecetes gramineus affinis) in Canada. Recovery Strategy Series. Environment Canada, Ottawa. Vii + 30pp.
This recovery strategy outlines a multi-species approach for the Horned Lark strigata and Vesper Sparrow affinis. It was recognized that there is considerable overlap between these species with respect to current and historical distribution in Canada, general ecological requirements, and principal threats to the species and their habitat. In addition, many of the professional biologists involved have extensive knowledge of both species. Adopting a multi-species approach to recovery planning also represents an opportunity to make efficient use of conservation resources. Current and historical populations of both species are patchily distributed and, together with isolated populations in the United States, each comprises a single metapopulation in the Pacific Northwest. Thus, recovery of Canadian populations will contribute significantly to the global recovery of the two subspecies.
