Timber recovery in Amazonian logged forests

Associated R scripts are available at: https://figshare.com/s/9873edea9c1e8fe98993

- plotInfo.csv: information on TmFO plots (location, year of logging, etc)

- volDynData.csv: volume dynamics data from the TmFO plots

- volRadam.csv: volume from RadamBrasil inventories

- paramsVolDyn.csv: parameters of the volume dynamics model

- paramsVolDynSite.csv: site-specific parameters of the volume dynamics model

- paramsDam.csv: parameters of the logging precision model (proportion of timber of the total volume lost during logging operations)

- paramsPropRecru.csv: parameters of the recruitment model.

- paramsFormind.csv: spatially-explicit parameters estimated with the Formind model. A sample of 100 values is given for every cell the Amazon-wide 1°-resolution grid.

Each column corresponds to one parameter, and each row is a set of parameters. For a detailed description of parameters, see: Piponiot et al. (2018). Assessing timber volume recovery after disturbance in tropical forests – A new modelling framework, in Ecological Modelling.

- spatVariables.csv: contains the proportion of harvestable area in every cell of the Amazon-wide 1°-resolution grid.

(B) Variables description:

- source: the data source (TmFO or RadamBrasil) of volume inventories

- site: the name of the site where the data was measured

- idPlot: plot identifier

- longitude, latitude: coordinates of the plot or pixel

- plotArea: area of the plot (in ha)

- yearLogging: year of logging

- year: census year

- volume: volume of trees > 50 cm DBH (in m³ha^-1)

- volGain: annual volume gain (in m³ha^-1yr^-1) from recruitment and growth of trees > 50 cm DBH since the previous census

- pRecruitment: proportion of volume gain from recruitment of trees < 50 cm DBH into the > 50 cm DBH size class

- volMort: annual volume mortality (in m³ha^-1yr^-1) of trees > 50 cm DBH since the previous census

- omegaTot: (pre-logging) proportion of timber volume (all potential timber species included) over the total volume

- omegaLoc: (pre-logging) proportion of volume in locally harvested species (i.e. all species actually harvested at this particular site)

- aG: gross volume productivity (in m³ha^-1yr^-1) of a mature stand estimated with the FORMIND model, using the methodology developed by Rödig, et al (2017).

- aGLoc: site-specific gross volume productivity (in m³ha^-1yr^-1)

- vclimax: volume of a mature stand (in m³ha^-1) estimated with the FORMIND model, using the methodology developed by Rödig, et al (2017).

- vclimaxLoc: site-specific gross volume productivity (in m³ha^-1yr^-1)

- pAreaLogging: proportion of area available for logging on the pixel, estimated as the proportion of the total area that is (i) is not a strictly protected area (according to the IUCN database); (ii) is within 25 km of a road or motorable track reported in Open Street Map; (iii) has a forest cover > 90% according to Hansen et al, (2013).
