  • Height: Total height (in cm).

  • DBH: Diameter at breast height (in cm).

  • N: Density (number of individuals/cell).

  • Z50: Depth (in mm) corresponding to 50% of fine roots.

  • Z95: Depth (in mm) corresponding to 95% of fine roots.

• shrubData: A data frame of shrub cohorts (in rows) and the following columns:

  • Species: Non-negative integer for shrub species identity (i.e., 0,1,2,...).

  • Height: Total height (in cm).

  • Cover: Percent cover.

  • Z50: Depth (in mm) corresponding to 50% of fine roots.

  • Z95: Depth (in mm) corresponding to 95% of fine roots.

• seedBank: A data frame containing the abundance of seeds for each species (in rows) and the following columns:

  • Species: Non-negative integer for shrub species identity (i.e., 0,1,2,...).

  • Abundance: Abundance class (0 - none; 1 - low; 2 - medium; 3 - high; 4 - very high).

• herbCover: Percent cover of the herb layer.

• herbHeight: Mean height (in cm) of the herb layer.

SpParams
