Comparison of pre-harvest and post-harvest productivity

An FGYA initiative.

In 2002 and 2003, FGYA compared site index (a measure of site productivity) in mature fire-origin stands with that in stands regenerated following harvest. Comparisons involved contemporaneous sampling of paired-plots in regenerated and parent stands, in combination with analysis of time-series data from permanent sample plots measured before and after harvesting.

Results were presented at the CIF/SAF Joint Convention in October 2004. Further work will focus on explaining the observed differences and examining the implications for growth and yield, plus participation in a broader dialogue on post-harvest stand development issues.
