Washington has three ecologically distinct breeding subspecies: E.a.strigata (Streaked Horned Lark): Very local and rare breeder in remnant grasslands in prairies and beaches of western Washington. E.a.alpine (Pallid Horned Lark): Locally common breeder in dry alpine habitats and very high elevations, and usually associated with rain shadows of major volcanoes, at high elevations in the northeastern Cascades and northeast Olympics. E.a. merrilli (Dusky Horned Lark): Abundant and widespread breeder throughout eastern Washington in steppe and agricutural habitats (especially wheat fields) at low elevations below the Ponderosa Pine zone.
E.a.strigata: Good habitats in core zone were grasslands, riparian habitats along the Columbia river (which include sand bars, wet grassy meadows, and adjacent south-facing grassy slopes on steep river banks), and ocean dunes with grass, but limited to sites with evidence of recent breeding. E.a.alpine: Good habitats in core zones were non-forested areas in the Mountain Hemlock, Subalpine Fir, and Alpine/Parkland zones of the Olympics and Cascades. E.a.merrilli: Core zones were steppe zones, the Oak zone, and the Ponderosa Pine zone locally in the notheast and within the Columbia Basin. Steppe and Oak zones were all good habitats except mid-to-high-density development, and in the Ponderosa Pine zone were agriculture, meadows and clearings.
E.a.strigata historically occurred in prairies throughout the Puget Trough. The widespread E.a.merrilli of eastern Washington utilizes disturbed grass patches and may benefit from some introduced plant species. E.a.alpine prefers dry, lichen-encrusted alpine habitats at high elevations in volcanic rain shadows.
