The products represent biomass estimates for four areas of interest in the Corridor Ankeniheny Zahamena (CAZ), Madagascar, generated using very high resolution imagery and based on field-collected plot information. The study extent aims to capture the drivers of deforestation in the Corridor Ankeniheny-Zahamena (CAZ). Multiple variables were incorporated into the sampling design, including elevation, slope, bioclimate zone, length of dry season, soil type, deforestation history (by epoch and elevation), and access. Based on these criteria,...

Forest inventory, dendrometric tree characteristics and aboveground biomass data in Ankeniheny Zahamena forest corridor, Madagascar

H.D. Razakamanarivo, T. Razafimbelo, A. Andriamananjara, A. Rianahary, M. Razafindrakoto & A. Harinirina
Data comprise a forest inventory (tree name (local, scientific, genera, family), diameter, height), dendrometric tree characteristics (tree species, weight (branches, leaves, trunk), diameter, height, coordinates, distance, location) and aboveground biomass data (litter and root mat depth, biomass and carbon stock of living vegetation (sapling, tree and understorey), non-living vegetation (litter), lying dead wood and standing dead wood) sampled in the Ankeniheny Zahamena Forest Corridor (remains of the evergreen forest of eastern Madagascar). Living vegetation includes...

Soil profile and chemistry data in the Ankeniheny Zahamena forest corridor, Madagascar

H. Razakamanarivo, T. Razafimbelo, A. Andriamananjara, A. Rianahary, M. Razafindrakoto & A. Harinirina
Data comprise soil profile (soil texture and pit description during fieldwork) and soil chemistry (bulk density, carbon content, carbon stock and organic carbon content obtained with thirteen carbon isotope analysis) from samples taken in the Ankeniheny Zahamena forest corridor, Madagascar. Data were collected as part of a project funded by the Ecosystem Services for Poverty Alleviation (ESPA) programme under work package 4 P4GES project, grant references: NE/K008692/1, NE/K010115/1, and NE/K010220-1.

Human-mediated biological exchange has had global social and ecological impacts. In sub-Saharan Africa, several domestic and commensal animals were introduced from Asia in the pre-modern period; however, the timing and nature of these introductions remain contentious. One model supports introduction to the eastern African coast after the mid-first millennium CE, while another posits introduction dating back to 3000 BCE. These distinct scenarios have implications for understanding the emergence of long-distance maritime connectivity, and the ecological...

H. Razakamanarivo, T. Razafimbelo, A. Andriamananjara, A. Rianahary, M. Razafindrakoto & A. Harinirina
Data comprise location (zone of interest, village name, site code, longitude, latitude, altitude and slope), local tree species name, tree code and tree diameter class of trees selected for direct measurements in the Ankeniheny Zahamena forest corridor, the remains of the evergreen forest of eastern Madagascar. Data were collected as part of a project funded by the Ecosystem Services for Poverty Alleviation (ESPA) programme under work package 4, P4GES project, grant references: NE/K008692/1, NE/K010115/1, and...

Wood specific gravity for trees in Ankeniheny Zahamena forest corridor, Madagascar

T. Ramananantoandro, A. R. Razafimahatratra, R. Razafinarivo, M. Rinaelintsoa & H. Razakamanarivo
Data comprise wood specific gravity (WSG) and density at 12% moisture content (D12) in wood cores sampled from trees in the Ankeniheny Zahamena forest corridor, the remains of the evergreen forest of eastern Madagascar. The data also include date of sample collection, zone identifier, core identifier, local and scientific tree name, tree height and diameter. Samples were analysed by UFR Sciences du bois de l'ESSA-forêts, Université d'Antananarivo. Data were collected as part of a project...

H. Razakamanarivo, T. Razafimbelo, A. Andriamananjara, A. Rianahary, M. Razafindrakoto & A. Harinirina
Data comprise root weight (fresh and dry), root biomass and carbon stock, root mat measurements, root architecture, litter measurements and pivot, stump and surface root data for trees selected using the Voronoi or Pit method and sampled in the Ankeniheny Zahamena forest corridor, the remains of the evergreen forest of eastern Madagascar. Data were collected as part of a project funded under the Ecosystem Services for Poverty Alleviation (ESPA) programme. Work package 4 P4GES project,...

Braun-Blanquet percentage vegetation cover and indicator species data in Ankeniheny Zahamena forest corridor, Madagascar

H. Razakamanarivo, T. Razafimbelo, A. Andriamananjara, A. Rianahary, M. Razafindrakoto & A. Harinirina
Data comprise records of percent vegetation cover using a category known as the Braun-Blanquet scale from a survey of indicator vegetation species carried out in the Ankeniheny Zahamena forest corridor in Madagascar. In addition, scientific name, local name, family name and life form (fern, shrub, herb, grass, vine or tree) of vegetation was recorded. Data were collected as part of a project funded by the Ecosystem Services for Poverty Alleviation (ESPA) programme under work package...

Topographical characteristics of sites in the Ankeniheny Zahamena forest corridor, Madagascar

H. Razakamanarivo, T. Razafimbelo, A. Andriamananjara, A. Rianahary, M. Razafindrakoto & A. Harinirina
Data comprise site information (site identifier, name, location, zone of interest, land use type, altitude, slope, topographic position and age of deforest and fallow) and historical information from local people in the Ankeniheny Zahamena forest corridor, Madagascar. Data were collected as part of a project funded by the Ecosystem Services for Poverty Alleviation (ESPA) programme under work package 4 P4GES project, grant references: NE/K008692/1, NE/K010115/1, and NE/K010220-1.
