Stand-level index

For each stand, a recreation index (RI) between 0 and 1 can be calculated as a function of the following variables:

For bare land and plantations (<2m height)

  • Age structure (RI increases with increased tree size diversity)
  • Dead wood occurence (RI decreases with increased abundance of dead wood).
  • Downed logs (RI decreases with increased abundance of downed logs. Percepted as hindering)
  • Harvest residues (RI decreases with increased abundance of harvest redidues)

The intercept is 0.3

For young stands > 2m, and before first thinning

As above, plus:

  • Pine and spruce proportion (RI decreases with increased occourence of conifer plants, broadleaves are preferred)

The intercept is 0.568.

For older stands

As above, plus:

  • No. of stems (Many large trees are preferred before small trees)
  • Soil damage (Occurence of soil damages from harvest machines etc. has a negative impact on RI.

The intercept is 0.569
