This year we'll have planted another 7 hectares of Guazuma ulmifolia at a density of 2mx3m or ~1700 trees/hectare using the Inga alley cropping method. They should have an average trunk section at least one foot square and 26' tall in 10 years. (ie 1x1x26x12= 312 board ft) so if you do the math at just $1/board ft then it's about $150/day/hectare. (ie 1700x312x1/10/365= ~$145). So 7 hectares makes your net worth increase by about $1000/day. The nice thing about these type of trees is that they re-sprout after harvest so no need to replant, ie continuous harvest indefinitely by cutting blocks only 1/10th of your trees per year, so the first cut trees are ready to cut again when the last, much bigger, are harvested.
(I've got some teak & mahogany planted too but not a big fan, too slow. I'm not a fan of non-native pines nor eucalyptus either.)
Those numbers go way up if you process the lumber and make furniture, flooring etc.
Also many trees are valuable medicinals. For example a water extract (ie tea) from the bark of the G. Ulmifolia tree (bolaina negra, not blanca) kills virus, lowers fever and reduces pain. See https://www.rain-tree.com/mutamba.htm
Along with bark from uña de gato with lemon (immune system stimulus), chanca piedra (other antivirus & more), tumeric with black pepper (anti-inflammatory), ginger, moringa and matico leaves (antibacterial). Is our anti-virus go-to, much better than what is available in pharmacies.
Plant trees in the tropics, then your money has roots and grows fast.
Different types of hardwoods give you a 5, 10, 20 year time to harvests.
Plus the monkeys, parrots etc like it (if you do it right). Many of my 5 yr old trees are already 10" dbh and 15m tall. Straight timber, some with cacao below.
~75 acres can increase your net worth by about $3k/day, indefinitely.
