History of Forestry (Butterfield 1994b, Nygren 1995)

  • Highest deforestation rate in Central America. In 1942, 70-75% of land was forested and in 1987, 29% was forested (66% of which was protected)
  • Protected forest reserves have different legal status
  • Departmental General Forestal
  • Most logging from land clearing (10% of volume felled is extracted), few mill own forest land and hence low reforestation incentive
  • Extractive logging can bring new roads
  • Some illegal logging
  • No forest (vs. cattle) credit incentives
  • Good forestry laws, but little enforcement. Need permit to cut anything >10cm. (Ley Forestal Bill 1990)
  • Most forest resources are private
  • In a commercial harvest, 12 m^3 is processed per 50 m^3 felled
  • Northern and Atlantic regions most important for logging (our study area)
  • Wood shortage/ importing in near future predicted
    Reforestation(Butterfield 1994b)
  • Negligible before 1979; 9,257 ha planted in 1989
  • 50-60,000 ha deforested/year
  • need to plant at least 37,000 ha per year to avoid wood importation
  • After 1979 reforestation incentives: CAF & FDF. Some land has been cleared just to receive incentives and limited number of species used for reforestation.
    Sustainable Forestry (Butterfield 1994b)
  • No sustained-yield experiments in Central America
  • One started by USAID in 1979, but funding cut in 1984
  • Need to be implement management and research simultaneously
  • National Parks and Reserves
