Managing rangelands: promoting and establishing sand dune fixing species: Stipagrostis pungens (Desf.) De Winter: a xerophytic quicksand- and dune-fixing species adapted to sandy deserts
Stipagrostis pungens is a perennial grass species which belongs to the Poaceae family. It is usually found with several erect culms, grows up to 1.5 m in height, and forms substantial tufts. It is a tall stiff glabrous grass with pungent leaves, and a C4 grass with sclerophyllous, spine-tipped, inrolled leaves, with sunken stomata. The root system extends laterally for a radius of 20 m or more. The roots are covered throughout their length by a sandy sheath, which is penetrated by the root hairs that occur throughout the entire length of the sheath.
Coupling land-use change and hydrologic models for quantification of catchment ecosystem services
Representation of land-use and hydrologic interactions in respective models has traditionally been problematic. The use of static land-use in most hydrologic models or that of the use of simple hydrologic proxies in land-use change models call for more integrated approaches. The objective of this study is to assess whether dynamic feedback between land-use change and hydrology can (1) improve model performances, and/or (2) produce a more realistic quantification of ecosystem services. To test this, we coupled a land-use change model and a hydrologic mode.
