The same management tools that provide Black-capped Vireo habitat will also maintain diverse and productive rangelands and provide recreational opportunities (Campbell, 1995). These tools include prescribed burning, selective brush management, grazing management, and reducing cowbird parasitism.

Prescribed burning conducted prior to March 15 can control small juniper, thus maintaining the relatively open shrublands preferred by vireos Campbell, 1995). Burns conducted under hotter conditions can set back plant succession in order to create new vireo habitat, but should only occur in areas not already occupied by vireos (Campbell, 1995).

The selective removal of juniper, mesquite, or pricklypear serves to maintain a relatively open shrub canopy and encourages growth of broad-leaf, deciduous shrubs, which are ideal conditions for vireo nesting (Campbell, 1995). Key woody plant species can be increased by stimulating basal sprouting, through mechanical methods such as chaining, roller chopping, or shredding (Campbell, 1995).

To provide adequate nesting cover for vireos, woody plants should receive only limited browsing during the spring and summer (Campbell, 1995). Grazing cattle instead of goats and sheep and controlling deer populations can keep browsing to a minimum. In addition, grazing management plans should be attentive to fine fuel needs for prescribed burning, if burning will be used to improve vireo habitat.

Grazing cattle and the easily-available sources of food associated with them (such as spilled grain) attract cowbirds. Grazing management can be used to remove cattle at critical times from areas where vireos nest, thus reducing the number of cowbirds in the area (Campbell, 1995). Cowbirds can also be trapped or shot. Mobile traps, placed near watering sites as livestock are rotated through pastures, have been used successfully to reduce cowbird numbers (Campbell, 1995).

More detailed management guidelines are available from the Texas Parks and Wildlife Department and the U.S. Fish and Wildlife Service for landowners and managers wishing to know more about rangeland management practices which improve habitat for the Black-capped Vireo (Campbell, 1995).
