acaciformis is not regarded as a commercially harvestable species so info specific to that species on rotation age, stocking,tending practices, and final crop and harvesting is not available. it is occcassionally planted for ornament (like the very closely related e. nicholii) and maybe for rehabilitation of natural areas within its native range but thats on a commercially miniscule scale. seeds NOT seedlings are collected the same way as most any other euc. ripe seed capsules are taken from mature plants and the capsules are then placed in a warm dry place. the warmth causes the capsuiles (aka "gum nuts") to open and release the dust like seed. sowing follows standard methods for eucs (google eucalyptus seed sowing) and does not require stratification. you may also look up eucalyptus commercial growing practices or fertilization and forestry practices for general information that might help. once again, this species is not a commercial forestry species so you will probably find little species specific info. if you can find a copy of the book "australian forest trees" you might find some useful info on the very closely related nicholii the would likely be applicable to accaciformis. good luck.
