Extended ecosystem function analysis - the next step for mine rehabilitation appraisals

摘要

Ecosystem Function Analysis/Landscape Function Analysis (LFA/EFA) is a long established and well received science-based monitoring and assessment technique for rehabilitated mines sites in Australia. It provides keystone evidence for the re-establishment of ecosystem function in the form of soil condition across a range of mine substrates and climatic conditions.LFA/EFA, in its current form is less concerned with subsequent ecosystem type and development in terms of vegetation composition and structural formation by which communities are recognised and characterised. Similarly, LFA/EFA is not concerned with their condition and, in particular, life-cycle states and dynamics which constitute the key foundation of sustainable ecosystems.The purpose of this paper is to consider whether there is scope for extending the LFA/EFA methodology for assessing revegetation success and ecosystem sustainability. Having examined the methodology and the ability to integrate an index-based assessment of composition, structure and condition, it is concluded that the LFA/EFA methodology can be extended. Hence, it is recommended that the suggested modifications are considered further and developed as necessary to enhance the current LFA/EFA methodology and also to meet biodiversity enhancement expectations.
