Prosopis cineraria is commonly known as Khejri,It is a Leguminous multipurpose tree.The tree prosopis have climatic adaptation so it can easily survive in a broad range of climatic variation.It is very useful tree and famous specially in desert area due to its spreadability and importance. It is also known as “Golden tree” or “Wonder tree” of the desert. Prosopis cineraria stem bark is useful i...

The majority of studies on woody–herbaceous interactions have focused on the effects of trees on grasses; relatively few have looked at grass effects on adult trees. In a two-year study in a temperate savanna in northern Texas, tree (Prosopis glandulosa) basal area increased significantly following removal of associated grasses, the response being highly variable in time and space. Tree respons...

Cultivation and grazing since the mid-nineteenth century in Texas has caused dramatic changes grassland vegetation. Among these is encroachment of native introduced brush species. The distribution quantity can affect livestock production water holding capacity soil. Still, at same time, improve carbon sequestration enhance agritourism real estate value. accurate identification species their ove...

Spatial patterns of soil dN reflect variation in rates of N-cycling processes across landscapes. However, the manner in which soil dN is affected by vegetation and topoedaphic properties under nonsteady state conditions is understood poorly. Here we propose and evaluate a conceptual model that explains how soil dN values will respond to changes in disturbance regimes (intensification of grazing...

Woody plant encroachment has degraded grassland and savanna ecosystems worldwide by decreasing herbaceous production and diversity, and altering these physiognomies toward woodlands. This study evaluated the long-term efficacy of fire and herbicide restoration strategies used in the southern Great Plains to reduce Honey mesquite (Prosopis glandulosa) dominance, restore a grassland/savanna physi...

Aerodynamic roughness length 0 ) and displacement height 0 ) are important surface parameters for estimating surface fluxes in numerical models. These parameters are generally determined from wind flow characteristics using logarithmic wind profiles measured at a meteorological tower or by balloon release. It would be an advantage to use measurements of land surface characteristics instead of w...

The genus Arctostaphylos consists mostly of chaparral shrubs known by the common name manzanita, and one of the widest ranging of these is A. glandulosa Eastw., distributed from Baja California to Oregon. Particularly in the southern half of its range it exhibits complex patterns of morphological variation that have long presented taxonomic challenges. Phenetic analysis of morphological traits ...

Savanna trees can impose aboveand belowground effects on the herbaceous layer by changing water, nutrients and microclimate. Proposed mechanisms governing savanna tree-on-grass interactions include: (1) improved fertility and structure of soils below tree crowns; (2) improved water relations of shaded plants; and (3) increased competition for light, soil moisture and nutrients. To assess the re...
