We take out every 5th row and then thin 2 on each side for maximizing pine production and keeping the best trees. IF it was mainly for wildlife I’d do every 3rd row and at 20 years not being thinned, I’d go ahead and thin down to 100 trees per acre (based on site) and just wait on the final cut when it’s majority CNS and prices spike. Imo your window for two thinnings has passed. If it was solely for pine value, I’d leave 140-160 trees per acre (based on site).
