About Us

Behind the Scenes

The Takaka Hill Biodiversity Group Trust (THBGT) understand that our unique lands form a corridor between Kahurangi and Abel Tasman National Parks. Intensive predator control by Friends of Flora in the Flora stream area of Kahurangi has resulted in flourishing populations of endangered species such as kaka, kea and whio and has enabled roroa to be re-established. Similarly, predator control by Project Janszoon in the Abel Tasman has enabled birds such as pateke to be re-introduced.

Without an equal response from Takaka Hill landowners, this privately owned corridor risks becoming an ark for re-invasion, threatening these unique birds and other native species benefiting as they spread out from the National Parks.

Landowner Leadership

The THBGT wants to lead the way as a landowner community group that adheres to good governance, financial management and transparency. We believe that landowners through their shared knowledge can make a significant difference through collective action to protect the unique native biodiversity of Takaka Hill.

Takaka Hill Biodiversity Group Trust at a Glance

A Bit of Background

The THBGT are driven by a single goal; to do our part in protecting New Zealand's native species for our children, our grandchildren and future generations. Our decision-making process is informed by evidence-based information, best practice project management, operations planning, monitoring and data evaluation. We strive to build collaborative relationships and make a positive impact from all of our actions.



The THBGT is committed to increasing native biodiversity on Takaka Hill. The work we do is aimed at providing a cooperative approach to solving New Zealand's biodiversity challenges.

  1. Create healthy native habitats

  2. Remove predators and pest species

  3. Increase the density and abundance of native forest birdlife

  4. Increase the density and abundance of native species found only on Takaka Hill


Predator Control

Reinforcing our Commitment

With this initiative, our goal is to: 

  1. Increase the density and abundance of native forest birds

  2. Increase the density and abundance of the Nelson green gecko. It is nationally listed as ‘at risk, declining’, with few recent reports elsewhere in the district. The Takaka Hill may, however, be one of its last strongholds, likely due to the extensive karst scrub and shrublands that favour it, and the elevation supporting generally low levels of ship rat compared to the lowlands.

  3. Increase the density and abundance of Powelliphanta hochstetteri

Pest Plant Control

One Step at a Time

With our Trusts goals always in mind,  we are working with Kaitiaki O Ngahere to develop a multi-year invasive weed control programme. With support from the DOC Community Conservation Fund, Kaitiaki is undertaking a pest plant survey on Takaka Hill that will result in a 5-year pest plant management plan.

  • Brachyglottis laxiflora is an NW Nelson endemic confined to marble and limestone

  • Limestone three finger is very common on the marble scrub slopes,  listed as ‘at risk, naturally uncommon’

  • Limestone mahoe is nationally listed as ‘at risk, naturally uncommon’

  • Greenhood orchid/ Pterostylis oliveri loves growing on marble

  • Spider orchid/ Corybas amaranthus; Birdsnest orchid/ Chiloglottis cornuta

Reinforcing our Commitment to protecting Native Birds

With between 3000 and 7000 Kea left in NZ, the worlds only alpine parrot. Kea loves nesting and hanging out together on Takaka Hill. But they are not the only birds found here there are also tui, korimako/bellbird, wax eye and kōtare/kingfisher. Ruru/morepork, riroriro/grey warbler, pīwakawaka/fantail,  kererū/pigeon, weka, toutouwai/robin, miromiro/tomtit, pipipi/brown creeper, and  kārearea/native falcon and parakeet/kākāriki


Perhaps the most significant trend in biodiversity management since the New Zealand Biodiversity Strategy was published has been the considerable growth in community based groups (and iwi) involved in community projects some of which are considerable.
