Abstract:

 

This study was conducted in an Imperata cylindrica and Saccharum spontaneum dominated grassland in Mt. Makiling, Calamba, Laguna to determine the survival of Gliricidia sepium stem cuttings following fire. Micro-biophysical changes under the plantation were monitored over a subsequent period of seven years. Gliricidia stem cuttings had 64% and 34% survival rates during the initial sampling immediately following fire, and final sampling seven years after the fire, respectively. Stem size and length of cutting storage did not significantly affect survival rate. The lower survival rate in the final sampling was due to fire treatment imposed one year after establishment. After seven years, vegetation composition and soil fertility had changed considerably.
