Biological Soil Crust

Soils of the arid zone are characterised by their low nutrient availability, poor biological activity, fine particle size, and high levels of salinity, alkalinity and sodicity. Biological soil crusts provide important functions in these systems; they bind soil, minimise erosion, fix carbon and nitrogen, and absorb rainfall. Once damaged or removed a biological soil crust can take a long time to restore.

Typically, contruction projects in arid areas remove vegetation and grade the soils; while these activities facilitate site access, they can also destroy the biological soil crust create soil erosion, dust pollution, community concerns, weed and vegetation issues and operational problems that can be experienced over the life of the development.  

We offer alternate site preparation, soil testing and an applied approaches to soil and vegetation management to stabilise soils and reduce dust pollution (see Cultana Case Study).  Soil testing can be particularly useful in the design phase of a project to inform planning and for developing strategies to reduce dust management and improve habitat regeneration.

Native seedbanks can become depleted in mature plant communities and following disturbance, may require bolstering to ensure an adequated regeneration response. 

Seedbank testing provides insight into your site, including its ability to recover after disturbance, patterns of expected growth (e.g. diversity and density of plant species), and your weed profile.

A Successional Approach

Our unique approach to revegetation involves a ‘ground up’ methodology, which floods a site with seeds of native colonising species. The use of colonising species provides rapid site stabilisation and initiates the process of recovery to build ecosystem function. These species add organic carbon to the soil, attract invertebrates, deposit seed, compete with weeds and provide cover. Colonising species in the arid zone can reproduce within 6–8 weeks of rainfall, bolstering the seedbank. These attributes provide a great catalyst for building ecosystems in the arid zone.
