Snipes Creek Rehabilitation Project
Part of the Greenhill to Black Hill Biolink
Biolinks Alliance with local landholders are working on the rehabilitation of Snipes Creek a tributary of the Campaspe River that has suffered from years of waste water contamination and degradation.
The project aims to repair the creeks natural hydrology, ecology and biodiversity; to improve water quality for the whole terrestrial system.
The plan was developed in consultation with a field of biodiversity, water ecology and engineering experts. Over the last year the rehabilitation works along the one kilometre section of the creek have really been taking shape.
The active on-ground works occuring are:
Woody weed management and removal. Primarily willow gorse and hawthorn (ongoing).
Noxious weed management (ongoing) texas needle grass and other exotic grasses.
Stock exclusion - fencing.
Construction of rock chutes creating leaky weir systems and a stock crossing ford.
Planting of seasonal soak areas with: sedges and grasses inclusive of: Carex appressa and tereticaulis, Poa labillardieri, Lomandra Llongifolia, Callistemon sieberi
Planting of riparian trees and shrubs inclusive of: Acacia dealbata: Silver Wattle, Banksia marginata: Silver Banksia, Eucalytus ovata: Swamp Gum, Eucalyptus camaldulensis: River Red Gum, Leptospermum lanigerum : Woolly tea-tree
Aquatic species planting which will take place in October 2022 (weather permitting) will consist of : Schonenoplectus tabernaemontani: a soft stem bulrush, Alisma plantago-aquatica: a common water plantain, Persicaria decipens: slender knot weed, Myriophyllum crispatum: a perennial aquatic marsh herb amongst many more.
Baseline Water Assessment - Aquatic Invertebrates
We are lucky to have two distinguished water experts in David Tiller and Leon Metzeling volunteering their time and expertise with the initial water health assessments. The first assessment took place in December of 2021 and focused on the invertebrate community structure, using the Waterwatch collection approach and EPA’s Rapid Bioassessment method.
The results for all three indices indicated that both sites are in a moderately poor condition. The positive signs are that some pollution sensitive taxa were present at both sites.
Limited water quality sampling was also undertaken at both sites. The indicators measured showed relatively good water quality at the time of sampling. Dissolved oxygen at site 1 was of concern at 47% saturation, however, it is not at a critical level known to be harmful to aquatic life.Reactive phosphorus at site 2 is also higher than would be expected, especially when the concentration at site one was very low.
This monitoring is an invaluable tool to assist us in understanding how the works have impacted the water quality over time. The next assessment will occur in late Spring.
FUTURE PLANS
These rehabilitation works are only the first stage in this creek’s rehabilitation. Biolinks plans to extend the works in both directions, involving multiple landholders and further enhancing the Greenhill to Black Hill Biolink.
Being a not for profit - non government organisation allows us to act as an independent body but it does put us under financial strain. We rely on philanthropy, grants, active landholder involvement and a large multi talented support base that we regularly call upon for assistance and expert advice.
Please consider supporting our invaluable work (with a difference) via the current fundraiser Treasures of this Land or through our ongoing philanthropic options. Of which there are many levels and ways you can participate. Check this page
