Acacias are evergreen, nitrogen-fixing plants ranging in form from ground covers to tall trees. There are more than 1200 species worldwide.
There are many roles for acacias in permaculture design such as increasing soil fertility through nitrogen fixation, rehabilitation of degraded soils and in reforestation. They are useful for erosion control due to their rapid growth and effective seed dispersal, and many species sucker readily.
Most species are extremely hardy and drought tolerant and some are salt tolerant, making acacias particularly valuable in arid regions as timber, firewood, food and fodder for stock during drought.
