Thin trees within forests: effects on young trees
A controlled study in 1989-2000 in tropical rainforest in Peru (Dolane, Gorchov & Cornejo 2003) found that five years after strip-clearing, thinning enhanced annual growth increase of new tree stems. In one cleared strip, annual growth increase for stems of three groups: recruits, stump sprouts and commercial species advance regeneration, was higher after thinning (0.13-0.19 cm) than in control plots (0.04-0.08 cm). In the other strip, annual growth increase for stems of commercial recruits, commercial stump sprouts, other recruits and other stump sprouts, was higher after thinning (0.20-0.28 cm) than in control plots (0.09-0.16 cm). Two 30×150 m strips were clear-cut in 1989. Each strip was divided into twenty 15×15 m plots. In 1996 all trees were thinned in two 30×45 m blocks in each strip. Data were collected in 2000.
