Summary

In Canada, the Henslow's Sparrow breeds in very small numbers in grassland habitats in southern Ontario. The Atlas of the Breeding Birds of Ontario detected a large decrease in the population's occurrence between the mid-1980s and the mid-2000s. In 2000, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) assessed the species as Endangered based on its small population and threats to its habitat (Environment Canada 2006).

Conservation and management

The main threat to the Henslow's Sparrow is the loss and degradation of moist, grassy habitats, both on its breeding and wintering ranges (Cadman et al. 2007, Herkert et al. 2002, Environment Canada 2006). Habitat management programs have been undertaken in Ontario to increase the area of grassland through shrub removal and mowing (Environment Canada 2006). Prescribed burns have been used on the wintering grounds in the United States to improve and maintain savanna habitats (Herkert et al. 2002). For information on the legal status of this species under the Species at Risk Act (SARA) see the SARA Registry
