Phytomanagement of biowastes using native ecosystems

Native plants and animals are often displaced from agricultural and silvicultural lands. Biowastes can enhance the reintroduction of native ecosystems into such environments, particularly if the soil has become degraded. In addition to providing shelter and ecological benefits, biowaste-assisted native ecosystems can generate revenue through the production of endemic products such as manuka honey and essential oils. Often, the products of sewage treatment are disposed into landfills or waterways because of negative public perception of their application onto agricultural land. When biowastes are used to enhance the establishment of native vegetation, the direct link to food is broken. We are investigating the use of native vegetation in farming systems, where the trees receive biowastes in the form of animal effluents. We are also researching establishment of native vegetation on degraded land using sewage sludge. In both cases, the role of the vegetation is to create value, either through saleable products or via ecosystem services.
