long wait for final harvest in teak and eucalyptus, want to understand thinning and whether it gives money in between

Thinning means removing some trees partway through the rotation so the remaining trees get more light, space and nutrients to grow bigger and more valuable. In a dense plantation, as the trees compete, you remove the weaker, crooked and closely spaced ones at intervals, and the thinned material itself can be sold, for poles, packing wood or pulp, giving intermediate income before the final harvest. In eucalyptus, thinnings and the short rotation plus coppice give returns relatively soon. In teak, thinnings from around 8 to 12 years onward give some money while the best trees are left to grow to high value final harvest at 20 to 30 years. So thinning serves two purposes, some cash in between and a better final crop. Plan the thinning schedule for your species and spacing, and sell the thinned material to local pole, packing or pulp buyers.
The thinnings from my eucalyptus sold as poles and gave me cash before the main cut. It also made the kept trees grow thicker. Worth doing on schedule.
