Effects of Prescribed Burns on Small Mammal Populations with Comments on Houston Toad Populations
… impacts on endemic species. Implementing prescribed fire helps restores the historic quality of the forest and effects can be monitored by indicator species. Bastrop State Park, home to the endangered Houston Toad (Bufo houstonensis) is located within the "Lost Pines" region of East Texas. …

Long-Term Effects of Burns on the Understories of Fragmented Suburban Forests in the Midwestern USA
… hereafter). Management actions, such as prescribed burns, conducted by natural resource managers to reduce the prevalence of non-native and invasive woody species can also affect herbs by altering the light and soil conditions in the understory and opening new sites for colonization, …

Factors influencing food availability for the endangered south-eastern Red-tailed Black Cockatoo Calyptorhynchus banksii graptogyne in remnant stringybark woodland, and implications for management.
… the present study was to assess the effects of prescribed burns on food availability to the cockatoos. The problem was approached by first, identifying the key components of food availability (capsule quantity, food value per capsule and tree characteristics) influencing the selection of trees …

Perspectives on oak savanna restoration in Minnesota: a dendroecological approach
… size class. Open and healed fire scars from prescribed burns were abundant at all sites, but no fire scars predated settlement. These results suggest that many areas we currently designate as “oak savanna” may not have many (or any) oaks predating European settlement of the area due to …

Estimating Heat Tolerance of Tree Buds in the Southeastern United States
… characteristics and fire tolerance may assist prescribed fire managers as they target control of specific undesired tree species while promoting desired tree species. Buds of six common hardwood species in the southeastern U.S. were harvested and exposed to different heat dosages using a …

The autecology of Widdringtonia Cedarbergensis in relation to its conservation management
… Intervals of 15 to 20 years between prescribed burns are recommended on the grounds that cedar stands will be afforded sufficient time to recover from the mortality of the previous fire, especially with respect to seed production. At the same time, this interval should be short enough …

Within-fire patchiness associated with prescribed burning in the northern Jarrah forests of Western Australia
… spatial scales) within the perimeter of a single prescribed burn. Of particular concern is the idea that prescribed burning operations, carried out under very restricted weather and environmental conditions, can lead to structural and floristic homogenization of the area within a burn perimeter. …

Fate of Eucalyptus marginata seed from canopy-store to emergence in the northern jarrah forests of Western Australia: Research to help improve regeneration following shelterwood treatment
… focus of the study was to assess the capacity of prescribed burns, under mild conditions, to produce seedbed conditions suitable for regeneration. Low intensity prescribed burns resulted in the production of suitable conditions for seedling regeneration; that is, leaf litter and understorey …

Fire effects on small mammals and vegetation of the Northern Chihuahuan Desert
… community and associated small mammal community. Prescribed burns were ignited during 13-15 June 1995 on 10 pairs (10 bumed. 10 unbumed) of 25- ha study sites. The 1995 bums reduced shmb (P = '» 006) and grass (P < 0.000) canopy cover to 64 and 16% of the preburn cover, respectively Complete …

Effects of Seasonal Burns on Avian Foraging in a Central Texas Ashe Juniper-Live Oak Savanna
… of woody species may account for this decline. Prescribed burning is one method for restoring remnants of grassland habitat, typically performed in wet, cool periods when fire behavior is more benign. Fires historically helped to maintain grasslands by suppressing woody plants and encouraging …

Ectomycorrhizal root tips from a plot undergoing regular prescribed burns also shohigher enzyme activity than those from unburned and wildfire plots over a year after burning. Additionally, russulaceae and thelephoraceae …

Savanna Restoration Through Prescribed Fire: Demographic and Physiological Responses of Oak and Hickory Seedlings and Saplings to a Changing Light Environment
Prescribed fire is a common tool for restoring and maintaining degraded oak savannas in the Midwest. Long-term success of restoration and maintenance ultimately depends upon new individuals entering the canopy. However, little is known about seedling and sapling response to this periodic …

Floristics, Conservation, and Restoration of Virginia's Piedmont Grasslands
… Park revealed that longer intervals between prescribed burns were associated with increases in woody plants and decreases in forbs, indicating that frequent management is necessary to maintain open conditions. To- gether, these results reveal that grassland management and restoration …

Influence of Woody Vegetation Composition and Structure on Fuels and Prescribed Fire in Mountain Longleaf Restoration
… a process known as “mesophication.” Although prescribed fire is commonly used to reverse mesophication, fire behavior, and thus prescribed fire utility for this purpose, is poorly characterized in mixed pine-hardwood stands with mesophyte encroachment. This study aimed to identify mechanisms …

The Effects of Prescribed Burning by the National Park Service on Pine -Oak Forests Within Great Smoky Mountains National Park
… Mountains National Park (GSMNP) has implemented prescribed burning of pine-oak forests in an attempt to restore and maintain this fire-dependent forest type, which is converting to a mesic broadleaf forest after a long period of fire suppression. One goal of the burning is to create suitable …
