The widespread clearing of native vegetation for agriculture has had a profound impact on Australia's rural landscapes. It has led to large declines in biodiversity, major problems with rising salinity and significant degradation of water quality in many streams. Putting trees back into landscape is part of the remedy, and well-planned farm forestry has the potential to make an important contribution.
Trees and Biodiversity focuses on how farm forestry might be applied to protect and enhance biodiversity in agricultural landscapes. It examines what is currently known about the biodiversity value of tree plantations, why biodiversity conservation is a desirable outcome, and provides practical guidelines for improving the biodiversity value of various forms of farm forestry.
Practical guidelines on how to improve biodiversity at the level of a stand of trees and at the scale of the broader landscape are also outlined, together with a discussion of some of the possible trade offs involved. A range of hypothetical farm forestry situations are discussed with suggestions as to how their value for biodiversity might be improved.
Trees and Biodiversity is the latest in the Joint Venture Agroforestry Program’s Design Guidelines series. It is aimed at landowners, farm foresters, extension workers, conservationists and anyone interested in exploring sustainable farming in an Australian context.
