Coombabah Lakelands Restoration project

Removing strangling weeds from threatened ecological communities so our native fauna and flora can thrive.

This restoration project is improving habitat quality in an important area of the Coombabah Lakelands, part of the Moreton Bay Ramsar Wetland. The project site is adjacent to feeding and roosting sites for internationally and nationally listed wading birds.

This project is improving forest health, increasing the open forest’s capacity to adapt to climate change-induced sea level rise, enhancing roosting sites for migratory shorebirds, and improving the recruitment of endemic species including Casuarina and Melaleuca as well as ground vegetation including native grasses and herbaceous species.

 

What we did

  • The project removed understory weeds that out-compete native plants for space and sunlight.
  • Weed removal was undertaken across 16 hectares.
  • Weeds were removed using a combination of hand weeding, cut scrape pint, drill and filling, and pot spraying.
  • The site was overrun with Asparagus vine, Lantana, Hawthorne, Groundsel Bush, and Cocos Palms. Target weeds include these as well as Broad Leaf Pepper Tree, Corky Passion Vine, Date Palm, Edible Passionfruit Vine, Mile-A-Minute, Ochna, Umbrella Tree, and White Passion Vine.

 

Measuring success

  • Eight hectares have been rehabilitated and maintained. Eight hectares of additional area have now been designated for rehabilitation, which will help reduce the reinvasion of weeds within the original site.
  • Follow-up maintenance is being undertaken to ensure the site is not reinvaded by weed species still present.

 

Why this project is important

The Coombabah Lakelands are an integral component of the Moreton Bay Ramsar Wetland. The project site is adjacent to feeding and roosting sites for internationally and nationally listed wading birds including the Bar-tailed Godwit, Whimbrel, and Eastern Curlew. These shorebirds travel shocking distances during their yearly migrations and desperately need the slowly diminishing pitstops around the globe to rest and feed.


Adjacent habitats include Saltmarsh and Coastal Oak forest, both listed in the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) as threatened ecological communities.
