Abstract
The species Pinus chiapensis is under severe pressure from forest conversion to agriculture and fuelwood cutting. These trends are certain to continue and methods for conservation and wise use of the genetic resource must be implemented soon in Mexico and Guatemala as well as in those countries where the species can be grown on a commercial basis. A total of 101 open-pollinated families from nine provenances of Pinus chiapensis have been established in trials and gene conservation banks by Smurfit Carton de Colombia since 1981. The best provenances for growth rate have been Cotzal, La Trinidad and Pohlo. A tree improvement program with grafted seed orchards is underway.
