Fungi are critical biodiversity in maintaining soil fertility. They drive major nutrient cycling processes in woodlands by decomposing dead plant and animal material, supplying nutrients to ensure the healthy growth of plants, and providing food for insects, small mammals and soil microbes. A diverse array of native fungi exists in woodland remnants but these fungi take a very long time, if they ever do, to self-establish in revegetation sites. The fungi need to be assisted back to promote sustained soil functional values for greater long-term sustainability of woodland revegetation, increased nature conservation, and improved landscapes.
This project has developed a unique sustainability strategy for woodland revegetation incorporating practical on-farm methods for landholders to reintroduce native macrofungi into revegetation schemes. Field demonstrations in two catchments (Swan-Avon, WA and Lachlan, NSW) have confirmed the practicality of successful reintroduction of native fungi as part of revegetation.
