Assessing The Impacts Of Grazing By Piney Woods Cattle And Controlled Burning On The Herbaceous Layer In An East Gulf Coastal Plain Longleaf Pine Woodland
<p>Fire and grazing are two disturbances which influence vegetation composition and diversity in many ecosystems. In the southeastern United States, longleaf pine plant communities are adapted to frequent fires and are likely to have been grazed by bison in the past. Though bison have been …

Herbaceous species diversity, redundancy and resilience of Mopaneveld across different land-uses
… affect plant diversity and function of the herbaceous layer. This study aimed to quantify the effect of various land-use practices on herbaceous plant community structure, which included productivity (biomass) as well as richness, evenness and diversity at species- and functional level. The …

Factors possibly inhibiting growth of herbaceous plants in the understories of Eucalyptus cinerea
… Their studies have shown that suppression of herbaceous layer species beneath the canopy of E. baxteri appear to be of an allelopathic rather than a competitive nature. Although the suppression of growth of herbaceous layer species under the understoreys of so many different Eucalyptus species …

Vegetation Responses to Seven Silvicultural Treatments in the Southern Appalachians One-Year After Harvesting
… characteristics and vegetation in the herbaceous layer (<1 m in height). Multivariate analysis techniques were used to analyze average differences in species abundance between pre-harvest and post-harvest and to relate post-harvest vegetation to microsite characteristics. Regional-scale …

Seed mix design and application to overcome seed limitation in floodplain forest restorations
… by assessing the impact of active seeding of herbaceous-layer plant species on species composition and diversity in restored sites. Although active seeding increased plant species diversity, it did not significantly alter the percent cover of planted species in the short term. My research …

The Effects of Fire on the Vernal Herbs of an Eastern Mesic Forest
… species, and density of exotics in the vernal herbaceous layer. To determine these effects, three sites in central Kentucky were surveyed prior to and following one of three treatments: spring burn, winter burn, or negative control. I conducted low-intensity spring burns in April 2010 and …

Recovery and Resilience of Appalachian Herbs
The herbaceous layer of rich cove forests in the Southern Appalachians represent one of the highest biodiversity habitats in North America. These forests, however, have undergone large-scale logging disturbance that has altered 99% of the original forested landscape, leaving few old growth forests. …

Biology of the Rare Woodland Perennial Trillium Pusillum Micheaux (Liliaceae) in Southwest Missouri
… where the exotic Euonymus fortunei dominated the herbaceous layer, was small (90 total stems) with an uneven and unstable stage structure. Soil pHs were 6.1 at Baker, 5.9 at Heckmaster and 6.5 at Hoover Woods. Mean leaf area index (LAI), a measure of light penetration through the canopy where the …

The ecological viability of wildlife conservancies in the Greater Mara Ecosystem
… (from remotely sensed data), and analyses of the herbaceous layer, further confirmed that regeneration of vegetation was occurring as a result of the new management regime. These results were combined along with a range of landscape attributes to create a site selection tool that identified 11 …

Herbaceous and woody plant establishment across hydrologic gradients in bottomland reforestation sites
… importance of abiotic factors on tree and herbaceous species establishment and growth, and there is a need for improved tools for identifying critical abiotic factors during pre-restoration planning. In order to determine the effect of hydrology and other abiotic conditions on plant …

Succession of semi-natural grasslands : spatially-explicit, mechanistic simulation considering various forms of land use
… species and plant functional groups of the herbaceous layer are modeled as compartments; their abundance is expressed as cover and only vegetative spread is considered. Difference equations are used to simulate their growth, which is adjusted using Briemle’s utilization numbers for cutting, …

The functional role of understorey herbs for litter decomposition in temperate forests
… function. For example, the understorey layer may play an equally important role in regulating the soil microclimate as the overstorey tree canopy. Additionally, the understorey layer may also enhance forest floor litter quality, by providing a diverse and nutrient-rich litter to the …

Spatiotemporal Distribution of Siberian Wildfires and Impacts from Meteorological and Climatic Factors
… concentrated in April–May. The rapid drying of herbaceous vegetation following early snowmelt provides favorable conditions for wildfire ignition. Over the past 20 years, the burned area in this region has shown pronounced inter‑annual variability, with no clear long‑term trend. The main fuel …
