Theme 3D: Development of new methodologies for measurement of restoration.

Full description

Deterioration of coastal marine and estuarine habitats is inevitable in areas where human development is active. This is particularly the case in New South Wales (and throughout Australia) where a very large proportion of the population live on the edges of the coast-line. To sustain biodiversity and to maintain ecological processes and functions (for its own sake or for anthropocentric, human reasons), it will be necessary, for a very long time, to recreate, rebuild or repair habitats (Programme 3: Restoration of Disturbed Coastal Habitats). The science of restoration of coastal habitats is virtually unknown, and there is no sensible theory or understanding of how to create habitat that develops ecological function and maintains natural biodiversity.

Most projects on restoration of habitat have unclear or no defined aims. Where there are clear aims, it is unusual, if not rare, to find any assessment of whether the aims are being achieved. The Centre for Research on Ecological Impacts of Coastal Cities (EICC)'s research in the area of ecology includes development and testing of protocols to allow assessment of the progress and achievements of programmes of restoration. This is complex because, like assessments of impacts, any actual restoration must be detectable against large natural variation in numbers and types of animals and plants from place to place and time to time. Also, the goals of restoration cannot depend on vague hopes of "restoring a balance" when it is known there is no "balance" to restore. So, sampling and experimental design, logical structures for statistical analysis and interpretation of results must all be developed, tested and improved.

The EICC has generated many scientific papers and theses from research projects on the development and testing of protocols to allow assessment of the progress and achievements of programs of restoration. The link to the URL provided in this record provides a link to this research.

Purpose
The purpose of this research is to improve sampling designs for measuring restoration in aquatic habitats so as to develop a practical scientific protocol to measure successful restoration.
