Trees/Forest question

[Kevin1012]

I want to make most of the map a forest, and I'm wondering if there's a tool/option/something that randomly places trees all over the map? Map size is 160x160 and making that a forest will take...forever <_< >_>...v_v

for each integer A from 1 to 'random number between 1 and XXX' (if its a big map make it a big number) do: destructible create a 'tree' at random point in 'rect'
