exampleTreeData: Example datasets

In miquelcaceres/IFNdyn: IFN forest dynamics and scenario analysis

Description

Data sets given to illustrate input data structures.

Details

• exampleTreeData Tree data corresponding to three forest plots. Data frame with 40 rows (tree records) and columns:

  • Provincia: Province.

  • Estadillo: Plot code within province.

  • ID: Unique plot code within IFN.

  • Species: Tree species code.

  • N: Tree density (individuals per hectare) that the record represents.

  • DBH: Tree diameter at breast height (cm).

  • H: Tree height (m)

• examplePrescriptionData Data frame with three rows (one per plot in exampleTreeData) and the following columns:

  • type: Either 'regular' or 'irregular'.

  • thinning: Either 'above' (i.e. thinning from above), 'below' (i.e. thinning from below), 'intermediate' (i.e. according to the current diameter distribution) or a string specifying diameter breaks and percentages (see details).

  • thinningBA: Threshold for basal area. Thinning will be applied if the basal area of the stand is larger than the speficied value.

  • thinningHB: Threshold for Hart-Becking index (if thinningBA = NA). Thinning will be applied if the Hart-Becking index of the stand is smaller than the speficied threshold value.

  • thinningPerc: Percentage of initial basal area to be cut.

  • finalMeanDBH: For regular management, threshold of mean diameter (in cm) separating thinnings from final cuts.

  • finalPrec: For regular management, string with percentages of basal area to be removed in each final cut ('40-60-100' means a three final cuts, where percentages of basal area to be removed each time is 40%, 60% and 100%).

  • plantingSpecies: Tree species code to be planted after the final cut.

  • plantingDBH: Tree DBH to be planted after the final cut (in cm).

  • plantingHeight: Tree height to be planted after the final cut (in m).

  • plantingDensity: Tree density to be planted after the final cut (in ind·ha-1).

  • finalPreviousStage: Previous stage in final cut (0 - means thinning interventions, 1 - means first final cut, 2 - means second final cut, and so on).
