Distribution and habitat
The range and numbers of this bird are decreasing, probably due to habitat loss of the grasslands that it depends on. However, it has heavily benefited from the Conservation Reserve Program formed by the United States Department of Agriculture, which has helped to stabilize its population. Following this, it was downlisted to Least Concern from Near Threatened in 2018.The Texas population was solely known from a brushfield near Houston and disappeared after devegetation due to industrial development in the 1980s. It was considered a distinct subspecies but is today considered to fall into the range of variation of the nominate subspecies. Likewise, the South Dakotan population formerly known as P. h. occidentalis has been synonymized with the nominate. The only remaining subspecies generally accepted are the eastern Henslow's sparrow and the western Henslow's sparrow, whose ranges are for the most part separated by the Appalachian Mountains.
