"Tree to 25 m high, root-suckering. Bark hard, furrowed, almost black." (WorldWideWattle ver. 2)

"Forms extensive open-forest communities usually on fertile clay and loamy clay." (WorldWideWattle ver. 2)

Brigalow mostly occurs on relatively fertile soils. It competes very strongly with pasture for water, light and nutrients. Consequently it has been cleared from a very large portion of its range and government bodies now actively protect some remaining areas.

Acacia harpophylla seed is not protected by a hard seed coat and has poor keeping properties compared to other Acacia species. Nonetheless the seed is collected and attempts at using it in rehabilitation via direct seeding are still made from time to time. Commercially viable collections are only possible infrequently although the very small collections required for tubestock propagation would be possible far more often. This only holds true where collectors are mobile over many hundreds of kilometres and have the experience to execute such a collection.
