Fish Habitat Resnagging Project

Penrith Council and the Department of Primary Industries (DPI) are restoring fish habitat at Emu Green Reserve and Fowler Reserve.

The project was created to introduce woody debris, such as root balls and logs, back into our river systems that were removed due to historical river clearing to help create natural habitat.

Logs and root balls are being placed along the banks of the Nepean River to encourage the native fish species populations to thrive. The works involve the use of machinery and will be undertaken by highly trained experts in this field.

This project commenced in 2020 and was completed in 2021. You can learn more about the project from this informative video by Soil Conservation Service.

What is resnagging?

Resnagging is putting snags (woody coarse debris) like root balls and logs back into our river systems that we removed due to agricultural purposes or protection of development. These snags are repurposed to create natural habitat.

Logs and root balls have been removed due to development, road upgrades and the aerotropolis and are repurposed as material to be used for conservation projects with biodiversity outcomes, such as the fish habitat restoration project. Repurposing these logs and root balls diverts them from being chipped or sent to landfill where they can’t be reused.

Why is it important to restore our native fish habitat?

Coarse woody debris such as logs, root balls and branches are important structural components of rivers such as the Hawkesbury Nepean River. The debris provides essential habitat for our aquatic and terrestrial organisms.

The re-introduction of complex habitat using root balls and logs with hollows or branches will improve the aquatic ecology, provide native fish refuge and other resources, and lead to an increase in numbers of native recreational fishing species such as the Australian Bass.

The benefits to the native fish species includes:

  • Potentially increasing species’ diversity by improving habitat complexity that will increase food, shelter and other resources.
  • Increasing potential breeding habitat for native fish species.
  • Increasing the potential for safe breeding/ spawning environments for native fish species and the microbes and invertebrates they depend on for food.
  • Providing protection from predators and high velocity rain events.
  • Benefiting the huge number of recreational fishers who use the Nepean River. 

What species of native fish will benefit from this project?

  • Australian Bass (Macquaria novemaculeata)
  • Australian Smelt (Retropinna semoni)
  • Bully Mullet (Mugil cephalus)
  • Eel Tailed Catfish (Tandanus tandanus)
  • Freshwater Mullet (Trachystoma petardi)
  • Freshwater Herring (Potamalosa richmondia)
  • Silver Perch (Bidyanus bidyanus)
  • the threatened Macquarie Perch (Macquaria australasica) 

How can I get involved?

There are some great opportunities for you to volunteer and get involved in helping us restore the fish habitat along the Nepean River. Activities will include tree planting, weed removal, learning more about the fish species local to Penrith, and assisting with the general rehabilitation of the riverbank.

Habitat Restoration Event Series 

We’ve partnered with Conservation Volunteers Australia (CVA) to deliver 27 community events each year in 2021 and 2022! The Habitat Restoration event series focuses on eight bushland reserves within the Penrith Local Government Area (LGA) which contain one or more threatened flora species. We’re inviting community members and volunteers to come along and plant trees and remove weeds to help restore habitat in these areas.

Each of the eight reserves will have multiple events held throughout the year. Events incorporate both an educational/interactive aspect and an on-ground activity.

On-site training, tools and refreshments provided. Bookings essential. Check out our What’s On events page for details.

This project is a three year project which commenced in 2019 and will be completed in 2022.

Trees for Mum and Trees for Dad

Trees for Mum is one of our longest and most cherished annual events. Trees for Mum and Trees for Dad are two special community events we host every year on Mother’s Day and Father’s Day respectively to celebrate and honour the mums, dad, grandparents, mother figures and father figures in our lives.
