Biodiversity management

Updated 24 November 2020 4:22pm



Our management activities focus on maintaining and restoring the best and most threatened examples of our native ecosystems and habitats of threatened plants and animals. The management tools we use with landowners and in regional parks include controlling pest animals and plants, facilitating legal protection and exclusion of stock, planting native vegetation, and improving fish passage. 

We work throughout the Wellington region to help protect, maintain and restore the local indigenous biodiversity (native plants, animals and ecosystems). Our efforts are guided by the GWRC Biodiversity Strategy.

Our biodiversity management work programmes include the following:


Key Native Ecosystems

These areas represent the best and most threatened examples of our native ecosystems. In these top priority areas we work to protect native plants and animals.

Porirua Harbour and Catchment  

Porirua Harbour is a nationally significant wildlife area. It is an important nursery for fish, hosts a range of coastal and wetland birds, and has large concentrations of cockles. The seagrass and saltmarsh habitats are also of regional importance. GWRC along with other agencies, iwi and the community are involved in the Porirua Harbour Catchment Programme, working to improve the health of the harbour and its catchments.

More information about the Porirua Harbour and Catchment programme can be found here.

Wairarapa Moana

Wairarapa Moana is the largest wetland system in the lower North Island. It has national and international importance for the indigenous plant and animal communities that are found there. Wairarapa Moana is home to native fish, some rare plants and a range of birds including some international migratory birds.  It remains a richly diverse and wild place but is being severely compromised by many threats to its ecology and water quality. The regional council along with other agencies, iwi and organisations are partners in the Wairarapa Moana Wetlands Project to restore the wetland treasures.
