Perspectives on oak savanna restoration in Minnesota: a dendroecological approach
… disturbances have diminished the extent of oak savannas throughout the Midwest and altered what few remnants remain. Although oak savanna restoration is of great interest to the public and reserve managers, scientists do not fully understand the intricate dynamics of the ecotone, leaving …

Breeding Bird Response to Post Oak Savanna Restoration Seven Years Post Management In Eastern Texas
<p>Oak savannas were once an abundant vegetation type in the Midwestern United States that have now declined to <1% of their original distribution. Historically, natural disturbances such as periodic fire and grazing maintained oak savannas, but these have been reduced or eliminated, resulting in …

Effects of Seasonal Burns on Avian Foraging in a Central Texas Ashe Juniper-Live Oak Savanna
North American grassland birds have been declining for the past three decades. Loss of habitat from urbanization, agricultural land use, and encroachment of woody species may account for this decline. Prescribed burning is one method for restoring remnants of grassland habitat, typically performed …

Herptile Abundance and Diversity in Response to Seasonal Burning on a Central Texas Ashe Juniper-Live Oak Savanna
… community of a central Texas Ashe juniper-live oak savanna. One trapping line, consisting of 1 drift fence, 2 pitfall traps and 2 funnel traps, was established on 12 treatment (6 on each burn treatment) and 6 control plots (unburned), for a total of 18 trap lines. Eighty-two individual …

Using Remote Sensing and Biogeographic Modeling to Understand the Oak Savannas of the Sheyenne National Grassland, North Dakota, USA
<p>Oak savannas are valuable and complex ecosystems that provide multiple ecosystem goods and services, including grazing for livestock, watershed regulation, and recreation. These ecosystems of the woodland-prairie ecoregion of the Midwestern United States are, however, in danger of disappearing. …

Understory vegetation patterns in oak savannas of the Missouri Ozarks
Indigenous oak savannas are among the most endangered natural communities in Missouri. Understanding the floristic patterns which characterize savannas is important for the management and restoration of these rare communities. The purposes of this investigation were to describe the plant …

Conservation biological control in a multi-strata agroforestry system
… plant structural and species diversity of native oak savanna. Advocates of the system claim that it will advance conservation goals by providing ecosystem services like habitat provision and carbon sequestration, but also provide localized ecosystem services that benefit farmers. Pest control by …

Determinants of native and exotic plant species diversity and composition in remnant oak savannas on southeastern Vancouver Island
… richness and composition in a highly fragmented oak savanna ecosystem on southeastern Vancouver Island. In sharp contrast to most reported results, I found a negative relationship between native and exotic richness at the regional scale, and no relationship at the local scale. Two extrinsic …

Foliar Herbivory on Understory Oaks as a Function of Forest Type and Prescribed Burning
Loss of oak seedling and sapling leaf area to insect herbivores has not been well characterized in Ozark forests, but may be a critical variable affecting current and future forest health. This study quantified loss of oak seedling and sapling leaf area to insect herbivores in recently burned or …
