We'd be so lucky to actually end up with a thousand productive mangos and a thousand productive avocados. The long-term plan is to harvest for personal consumption mostly, and raise pigs as well as Pacas (a local jungle animal) to eat the fallen fruit and produce meat. Obviously the trees will need to be at least 10 years old before that's even feasible. Aside from Mangos, we focused mostly on fruits that would produce keto food, which will provide better sustenance, than just sugary dessert-type fruits. We planted some Metohuayo, which is a native jungle nut. The Majambo (a species I showed in my video) produces really good seeds that people roast over fire. They are basically like a fat, giant version of pumpkin seeds.
Maintenance is the most difficult topic. I wish I had one of those forestry mulchers, and a reliable mechanic for it. Our property is so steep though, that I wonder if even one of those skidsteer forestry mulchers wouldn't flip over. We own three weedwackers, which are time consuming, and it's not always easy to find help. The Husqvarnas we own have not been very reliable. We bought a Maruyama recently, which is a Japanese brand...supposed to be more reliable.
To help with maintenance:
Short-term: Pastured Poultry (Muscovies, Geese, Chickens)
Mid-Term: Cattle, Water Buffalo, Sheep, Goats, Kunekune pigs?
Long term: Fruit pigs, Pacas, Pacaranas, Goats?
The trees need to be a certain size before we can start using some of the animals.
