Table 1. Restoration and research objectives of the Upper Hunter River Rehabilitation Initiative, a combined research and restoration project (from Keating et al. 2008).
| 1. To understand through monitoring
and experimentation the dynamics of the riverine ecosystem
of the Hunter River and its response to rehabilitation.
| 2. To create through revegetation
of a 10-km stretch of the Hunter River a riparian plant community
that (i) uses species that occurred or likely occurred on
the original riparian and floodplain landforms, (ii) becomes
self-sustaining, (iii) provides a habitat for terrestrial
and aquatic indigenous species, (iv) provides a source of
propagules for the natural colonization of native species
downstream, (v) ensures bank stability equivalent to that
provided by the existing willows (Salix spp.), (vi)
improves water quality, and (vii) contributes to carbon storage.
| 3. To install large instream wood
structures that (i) reduce bank erosion; (ii) contribute to
the storage and redistribution of sediment to generate dynamic
channel morphology appropriate to the local setting; (iii)
contribute to the instream storage, transformation, and bioavailability
of nutrients; and (iv) increase habitat diversity for fish
and other aquatic biota.
| 4. To contribute to community
education and involvement in riverine rehabilitation.
| 1. To determine the effects of
land use and geomorphic change throughout the upper Hunter
catchment and the resultant downstream impacts on reach-scale
| 2. To understand (i) how changes
in land use affected fluvial geomorphic patterns and processes
and (ii) how riparian revegetation and the reintroduction
of instream wood affect contemporary fluvial geomorphology.
| 3. To understand the patterns
and processes governing the establishment of vegetation (including
exotic species) in a disturbed riparian setting.
| 4. To understand how reintroduction
of instream wood affects (i) channel bathymetry, (ii) benthic
and hyporheic processes and biota, and (iii) fish communities.
| 5. To understand how floristic
changes in the riparian zone and geomorphic effects of instream
wood reintroductions affect the instream retention and breakdown
of organic matter.
