Macquarie perch are a medium sized freshwater fish native to the Murray-Darling Basin. They were historically found throughout the slopes and upland areas of the southern Murray Darling Basin and where a popular target for fishermen. However, populations began to crash by the mid 1900s because of river regulation, fish passage barriers, introduced species, sedimentation and pesticide use. By the 1970s, Macquarie perch were considered to be seriously threatened with extinction. Since then, the species has continued to decline, with populations considered viable as recently as 2005 having declined or disappeared.

On Friday 27 November the CMA’s Hunter Community Reference Group had the opportunity, prior to their quarterly meeting, to find out about issues and projects being managed in the Allyn River catchment.

The group started their day with a visit to Noel Jupp’s Riverdene Nursery at Gresford. Noel is a member of the reference group and for the past 40 years has been propagating provenance native plants and supplying them to landholders and Landcare groups in the region. Noel gave the group a tour of the property, where he has planted over 1000 trees—with plans for many more!

This time last year the CMA was preparing to open the first of the Ironbark Creek floodgates as the first physical step in reintroducing tidal waters into Ironbark Creek and low lying areas of Hexham Swamp, to help re-establish the estuarine wetland habitat that was present in the area prior to the 1970s.

As part of its Hexham Swamp Rehabilitation Project the CMA applied to the NSW Department of Planning to open the floodgates in a staged manner to maximise the opportunity for transition vegetation and habitats, while minimising the effects on resident communities.

The CMA was recognised recently for its part in a number of innovative coastal projects, taking out the 2009 NSW Coastal Award for Community Involvement at the Annual NSW Coastal Conference in Ballina.

The Marine Discovery Series is a free public lecture series that has been running for a number of years and has proved to be an extremely successful way of introducing people from all walks of life to our fascinating and diverse underwater world. Held at venues from Harrington to Terrigal, presentations have included spectacular underwater photography, the secrets and lives of Seahorses, Port Jackson sharks, sex-changing Sea Wrasse, and marine molluscs, and the science of the surf.

Prior to the major flood experienced across the Hunter in June 2007, the Wollombi Brook was up to 75% infested with the noxious aquatic weed Salvinia.

Salvinia is known to grow more rapidly through the warmer months, and with the higher temperatures experienced throughout November, the chances of the Wollombi area becoming re-infested this summer are high.
