Managing Longleaf Forests for Grassland and Other Songbird Habitat Mark D. Smith Alabama Cooperative Extension System School of Forestry and Wildlife Sciences Auburn University
Pine-grassland System • Most ecologically diverse system in the south • Periodic natural disturbance • Disturbance-dependent species • Early succession species • Specialists
75 0 Time in Years Plant Succession • Plant communities change over time • Wildlife resources change • Habitat quality changes
As vegetation changes, bird communities change • At planting and soon thereafter • ~50 species • Grasshopper sparrow • Eastern meadowlark • Horned lark • Savannah sparrow
As vegetation changes, bird species change • Shrub-scrub understory • ~3-10 years after establishment • ~50 species • Indigo bunting • Yellow-breasted chat • Common yellowthroat • Prairie warbler
As vegetation changes, bird species change • Forest Birds • ~50 species • Bachman’s sparrow • Brown-headed nuthatch • Blue grosbeak • Pine warbler • Red cockaded woodpecker
Herbicide application October 1998 March 1999 Fertilizer August 1999 Prescribed fire March 1999 “Re-capturing” unmanaged sites
What about thinning? • Opening up the overstory • Sunlight to the forest floor • Combine with prescribed burning
An example of the effects of thinning on understory growth
What affects bird use? • Short and Long Term • Planting density • Canopy closure • Understory composition---what’s on the ground
Management at Establishment • Ground vegetation is important! • Control invasive exotics • Bahiagrass • Bermudagrass • Site prep • High intensity = less ground cover • Low rate = more ground cover • Planting of native forbs and grasses • Bluestems
Realistic Expectations • Not going to happen overnight! • Several species are territorial • Depends on: • Stand size • Stand shape • Location to other similar stands • Location to other habitats • Region of the state • With periodic fire, understory will change over time
