Site Index Equation for Smallholder Plantations of Gmelina arborea in Leyte Province, the Philippines

  title={Site Index Equation for Smallholder Plantations of Gmelina arborea in Leyte Province, the Philippines},
  author={Jerome K. Vanclay and Jack Baynes and Edwin D. Cedamon},
  journal={Small-scale Forestry},
The equation SiteIndex = Height × Log(IndexYear+0.5)/Log(Age+0.5) is suggested as a robust way to classify site index of small private Gmelina arborea plantations in Leyte province in the Philippines. Estimates of site index from this equation correlate well with other indicators of site productivity, including the observed mean annual volume increment and soil depth. An alternative equation based on slope and soil depth offers an indication of potential site productivity on unforested sites… CONTINUE READING
