Detecting biophysical properties of a semiarid grassland and distinguishing burned from unburned areas with hyperspectral reflectance
This paper examines the utility of hyperspectral remote sensing to detect fresh and dry biomass, water content, and plant area index of burned and unburned grassland in southern California. Contrary to many previously published reports, the Normalized Difference Vegetation Index (NDVI, a vegetation greenness index) was not a good indicator of any of these important biophysical properties in eit...
متن کاملPlant Biodiversity Drivers in Brazilian Campos Rupestres: Insights from Phylogenetic Structure
Old, climate-buffered infertile landscapes (Ocbils) have attracted increasing levels of interest in recent years because of their exceptionally diverse plant communities. Brazil's campos rupestres (rupestrian grasslands) are home to almost 15% of Brazil's native flora in less than 0.8% of Brazil's territory: an ideal study system for exploring variation in floristic diversity and phylogenetic s...
متن کاملImpactos potenciais das alterações no Código Florestal sobre a vegetação de campos rupestres e campos de altitude
article+bn04310042010. Abstract: The Brazilian campos rupestres and campos de altitude are characterized by mosaics of vegetation types and are better represented above 900 m in the Espinhaço Range and above 1500-2000 m in the Serra do Mar and Serra da Mantiqueira. They bear high species richness at local and regional scales and numerous relicts and endemisms. These montane refuges, which are o...
متن کاملTemporal and spatial variation of episodic wind erosion in unburned and burned semiarid shrubland.
Redistribution of soil, nutrients, and contaminants is often driven by wind erosion in semiarid shrublands. Wind erosion depends on wind velocity (particularly during episodic, high-velocity winds) and on vegetation, which is generally sparse and spatially heterogeneous in semiarid ecosystems. Further, the vegetation cover can be rapidly and greatly altered due to disturbances, particularly fir...
متن کاملAvian Nest Box Selection and Nest Success in Burned and Unburned Southwestern Riparian Forest
Riparian forest communities in the southwestern United States were historically structured by a disturbance regime of annual flooding. In recent decades, however, frequency of flooding has decreased and frequency of wildfires has increased. Riparian forests provide important breeding habitat for a large variety of bird species, and the effects of this altered disturbance regime on birds and the...
