VEGETATION MANAGEMENT PLAN for Bidjigal Reserve - Land

Vegetation Management Plan - Bidjigal ReserveThe lowering of the light levels in a rainforest/closed forest (by reforming the canopy) promotes theregeneration of rainforest canopy species, but reducing light levels in dry sclerophyll woodland orheath decreases the diversity and numbers of indigenous species and promotes the growth of wetgully species and frequently of exotic moisture-loving weeds.Light readings can be taken in correlation with the soil temperature readings set out above.Readings should be taken both in clearings or light gaps and under the tree canopy.The health of the litter layer - this can be recorded by observing the cyclical build-up andbreakdown of the fallen leaves, the appearance of the soil (whether compacted or friable), thepresence of small animals in the litter layer and the production of soil fungi, as indicated by fruitingbodies on the surface and thread-like mycelia in the soil. Simple measurements such as the depth oflitter or percentage of groundcover are important. This information will provide clues to otherprocesses occurring on the site over time.Rainfall readings - these can be obtained from the local meteorological station or taken on site.Determine the local rainfall pattern. Avoid weeding in hot weather when the soil is hard or in thewet season when the ground is so boggy that mud is churned up. Very dry periods are reflected inthe survival rate of seedlings, so if tubestock planting is planned, defer planting until regular rainsare expectedUBM Ecological Consultants Pty Ltd
