1 Determining the mechanisms by which invasive species exclude natives is critical for conserving and restoring native populations in impacted habitats. In recent decades the grass Phragmites australis has been aggressively invading coastal marshes of North America, with monocultures often replacing diverse assemblages of plants. 2 Our objective was to quantify how P. australis modifies the abi...

BACKGROUND Many different feedstocks are under consideration for the practical production of biofuels from lignocellulosic materials. The best choice under any particular combination of economic, agronomic, and environmental conditions depends on multiple factors. The use of old fields, restored prairie, or marginal lands to grow biofuel feedstocks offers several potential benefits including mi...

We studied short-term (1–3 years) responses of plant species and functional group abundances, richness, evenness, diversity, and similarity following cessation of 25 years (1972–1997) of herbicide application in a remnant of Blackland Tallgrass Prairie in central Texas. Substantial increases in plant cover from 1998 to 2000 were observed for annual forbs (359%–900%), primarily attributable to f...

Food plots may increase the value of hunting leases, make deer more visible for viewing opportunities, and improve the diet quality of deer. However, planting food plots is not a replacement for poor habitat management. Maintaining deer densities within the carrying capacity of the habitat, sound livestock grazing management, and maintaining quality habitat should be the first priorities of any...

seed bank is a central topic for plant community restoration. we determined the potential and regeneration capacity of soil seed banks of woody plant patches in conservation of the vegetation in an alpine habitat, since vegetation has completely disappeared in some sites by intensive grazing in the habitat. the study was done in mountainous area of alborz in iran. a total of 20 individual shrub...

Information on different rangeland plants’ nutritive values during variousphonological stages is of importance for the rangelands management. This information helpsrangeland managers to choose proper grazing times to achieve higher animal performancewith no detrimental effects on the rangeland vegetations. Effects of various plant parts’phenological stages and vegetation types on reserve carboh...
