LIDAR AND OBECT-BASED IMAGE ANALYSIS AS TOOLS FOR MONITORING THE STRUCTURAL DIVERSITY OF SAVANNA VEGETATION
LiDAR savanna heterogeneity biodiversity conservation monitoring structure eCognition
2015/8/19
Savannas are heterogeneous systems characterized by the coexistence of grasses and woody trees. Riparian zones are dynamic parts of savanna landscapes with structurally diverse woody vegetation. Growi...
SPECTRA OF MIXED PIXELS: DO THEY REPRESENT THE ACTUAL LAND COVER ON THE GROUND? - A CASE STUDY FOR A WET SAVANNA ECOSYSTEM IN UGANDA
Wet Savanna Ecosystem Wood-Grass Mixtures Mixed Pixels
2015/3/11
Due to increased availability and affordable cost of TM7 data, one envisages its widespread use for land cover mapping in many developing countries. There is need to establish not only the potential b...
BIOMASS ESTIMATION OF FOREST AND SAVANNA TRANSITION VEGETATION ZONE BY JERS-1 AND SIR-C BACKSCATTER DATA

The inventory and monitoring of transition zones between tropical rain forest and savanna formations in Brazilian Amazonia are an essential step for an accurate analysis of global change and biodivers...
RELATIONSHIP BETWEEN SAVI AND BIOMASS DATA OF FOREST AND SAVANNA CONTACT ZONE IN THE BRAZILIAN AMAZONIA
Biomass Tropical Rain Forest Savanna Vegetation Index Amazonia
2015/2/2
The Brazilian Amazonia presented the important dynamic changes in land use/land cover in the last two decades, mainly at the forest and savanna transition zones, due to human activities related to sel...
NDVI MEASUREMENTS OF NEOTROPICAL SAVANNA PHYSIOGNOMIES A GRADIENT OF: BIOMASS, STRUCTURE AND PHENOLOGY CHANGES
Difference Vegetation Index Classification Dynamics Climate Season Cerrado Phenology Vegetation Physiognomies
2015/1/6
The NDVI (normalized difference vegetation index) has shown to be a good predictor of green vegetation density for several vegetation types. The Brazilian xeromorphic vegetation, called Cerrado, compr...
Prospects of photon counting lidar for savanna ecosystem structural studies
Photon counting lidar ICESat-2 MABEL Savanna Canopy height
2014/12/4
Discrete return and waveform lidar have demonstrated a capability to measure vegetation height and the associated structural attributes such as aboveground biomass and carbon storage. Since discrete r...
Effects of mammalian herbivore declines on plant communities: observations and experiments in an African savanna
abiotic gradients, community structure, East Africa
2015/11/13
In this study, we examined the interactive roles of soil,
rainfall and livestock in modulating the response of local
plant communities to large wildlife declines. We investigated
these interactions...
