BIOMASS

Estimating Aboveground Biomass and Its Uncertainty in Tropical Forests

Contains functions to estimate aboveground biomass/carbon and its uncertainty in tropical forests. These functions allow to (1) retrieve and to correct taxonomy, (2) estimate wood density and its uncertainty, (3) construct height-diameter models, (4) manage tree and plot coordinates, (5) estimate the aboveground biomass/carbon at the stand level with associated uncertainty.

  1. retrieve and correct the taxonomy;
  2. estimate the wood density and its uncertainty;
  3. construct height-diameter models;
  4. manage tree and plot coordinates;
  5. estimate the aboveground biomass/carbon at the stand level with associated uncertainty;

News

  • version 2.1
  • bugs correction
  • add a vignette for the managment of the plot
  • add few tricks for the summaryByPlot
  • add of a function to convert tree relative to absolute coordinates
  • version 2.0
  • code optimization of most functions
  • new functions: computeFeldRegion, attributeTree, correctCoordGPS, cutPlot, latlong2UTM, numberCorner, summaryByPlot, updateCache
  • Re-writing of the dataset Karnataka forest, there were missing stems in the previous version of this database
  • version 1.2
  • Duplicated genera from the plantList have been fixed in the "genusFamily" dataset (e.g. The family Jungermanniaceae was given for the genus Massularia, now the dataset gives the Rubiaceae family)
  • version 1.1
  • The NouraguesHD dataset has now taxonomic information
  • The warning message from the computeAGB function has been removed
  • The correctTaxo function have been slightly modified to handle species names not recognized by TNRS
  • The getWoodDensity function has been slightly modified to deal with NA values in addWoodDensityData, which is now a data.frame of three colums and not four (the family column is now internaly built).
  • The computeAGB and AGBmonteCarlo functions have an additional argument: Dlim (see help).
  • The AGBmonteCarlo function has now an option to propagate error up to the carbon estimate (see the argument Carbon).
  • version 1.0 Initial version of BIOMASS
