Project Description:

The Taiaotea–Rothesay Bay Catchment Custodians Project is part of the wider Restore Hibiscus & Bays Stream Restoration Programme , which aims to restore waterways throughout the 34 catchments within the Hibiscus & Bays Local Board area, connecting native biodiversity across our significant ecological areas (SEAs) and other fragmented native ecosystems and contributing to the protection of the Hauraki Gulf Marine Park – Tīkapa Moana/Te Moana-nui-ā-Toi. 

The catchment

Taiaotea catchment is approximately 4.2 km2, located between the boundary of East Coast Bays road to the west and down to Browns Bay beach and coastal cliffs to the east. The smaller Rothesay Bay catchment is 0.73km2 and neighbours Taiaotea catchment immediately to the south. Both catchments, although highly developed, still contain rare examples of swamp maire, fragmented pūriri and mature coastal pōhutukawa, some of which have been designated as significant ecological areas (See catchment map here).  There are approximately 9,373 metres of streams and tributaries running through the catchments, 4,443 of which is above ground.

Taiaotea catchment hosts one of the last examples of the ‘threatened-nationally critical‘ mature Syzygium maire (swamp maire) within Bushglen Reserve, providing an extremely valuable seed source. Kākā have even been sighted in and around Bushglen. There are also reserves of tawa, kohekohe, rewarewa, hĪnau, podocarp forest (WF14) next to Northcross Intermediate School.

The work so far

In parts of Taiaotea stream, daylighting projects are underway, restoring what once was the riparian zone for the stream.There are multiple ongoing community stream and coastal forest restoration projects, involving volunteers and local schools (Browns Bays and Northcross Intermediate). These are mostly based around the water course and riparian areas and include weeding, mulching, planting, water quality monitoring and macroinvertebrate surveys in collaboration with Whitebait Connection. Please refer to the 2017 Taiaotea Stream Restoration Plan for further details. 

Northcross Intermediate School is involved in various projects removing environmental weeds within their neighbouring reserve, as well as seed propagation in a nursery onsite. Bushglen Reserve at the top of the catchment has in place extensive community trapping activity for rats and possums in and around the reserve (public & private land).

In various parts of the Taiaotea and Rothesay Bay stream, kokopu have been found as well as iinanga spawning sites. Whitebait Connections – funded by the Hibiscus and Bays Local Board and Auckland Council Healthy Waters – is working with local schools such as Browns Bay school and the community to help protect inanga spawning sites within the catchments, providing educational workshops and water quality testing.

Our Project

The Taiaotea-Rothesay Bay Catchment Custodians project will link up this existing restoration activity within a comprehensive catchment-wide stream restoration strategy. This will help to increase the impact of our work and connect habitat for our native wildlife to migrate between significant ecological areas and other fragmented native ecosystems within Taiaotea and Rothesay Bay catchments and across the entire Hibiscus & Bays Local Board area. Ultimately, the Taiaotea-Rothesay Bay Catchment Custodians project will connect with other catchment-wide stream restoration projects, including Long Bay- Awaruku and Campbells Bay, as well as other large restoration and pest control projects along the Whangaparaoa peninsula (Forest and Bird Pest Free Hibiscus Coast) and around Okura Bush (Friends of Okura Bush and Pest Free Okura).

The Taiaotea-Rothesay Bay Catchment Custodians project will involve:

• Education for landowners, residents and visitors on the negative effects for our waterways of pollutants and waste
• Water quality monitoring
• Native planting 
• Pest plant control and maintenance

We anticipate the entire Taiaotea-Rothesay Bay Catchment Custodians project will be completed across 5 years, with the aim to restore the entire streams and tributaries throughout the Taiaotea-Rothesay Bay catchments.

We need your help

We are currently seeking funding to initiate Year 1 of the Project. In Year 1, we will carry out pest plant control work, including weed removal and appropriate disposal, from July to April 2020-21, preparing the Year 1 sites ready for planting. We will plant the Year 1 areas in May to July 2021 and continue with post planting maintenance from July 2021 to 2024.
