Differences in drainage, variations in soil type (pine trees on sandy soil, deciduous trees on loamy soil, etc.) and salinity, the effects of blowing wind (which drives snow off the hills into depressions, affecting soil quality), and the historic activities of humans all combine to create the mosaic character of the region.
The top layer of the understory is the sub-canopy composed of smaller mature trees, saplings, and suppressed juvenile canopy layer trees awaiting an opening in the canopy. Below the sub-canopy is the shrub layer, composed of low growing woody plants. Typically the lowest growing (and most diverse) layer is the ground cover or herbaceous layer.
The shortgrass prairie is an ecosystem located in the Great Plains of North America.The two most dominant grasses in the shortgrass prairie are blue grama (Bouteloua gracilis) and buffalograss (Bouteloua dactyloides), the two less dominant grasses in the prairie are greasegrass (Tridens flavus) and sideoats grama (Bouteloua curtipendula).
The trunk diameter often ranges from 46 to 88 cm (18 to 35 in); depending on the growing conditions, however, open-grown trees can attain diameters of up to 153 cm (60 in). The trunk remains free of branches until some distance up the tree on forest grown trees, while individuals grown in the open are shorter and thicker with a more rounded crown.

The Ogallala aquifer, or the High Plains aquifer, is an integral fresh water source for the entirety of the Great Plains region, providing drinking water to 80% of the population and irrigating 13 million acres of land. Precipitation, seasonal lakes, and prehistoric water reserves serve as sources of water for the aquifer, which lies beneath ...
The predicted outcome of global warming in this subtropical region, is the reduction of plant/animal productivity and growth. Another effect would be that the increase of climate warming would also lead to tree mortality affecting not only the pine trees located in the Sierra Madre Occidental but also other pine trees in the surrounding areas.
The term "montane" in the name of the biome refers to "high elevation", rather than the ecological term that denotes the region below the treeline. This biome includes high elevation ( montane and alpine ) grasslands and shrublands , including the puna and páramo in South America, subalpine heath in New Guinea and East Africa, steppes of the ...
