Seventh Successful Season

NZ Dotterel Watch Partnership - Coromandel Peninsula

NZ Dotterel Watch is a programme focused on assisting the survival of the threatened New Zealand Dotterel, a native bird that inhabits coastal areas in only a few regions throughout New Zealand. The programme was conceived in 1995 when workers at the Martha Mine observed dotterels nesting on the waste rock embankment's haul road. It developed into a partnership between the Department of Conservation (DOC) and Newmont Waihi Gold (NWG).

Since the programme's inception, NWG has supported it by providing a vehicle and funding. DOC uses the funding to support a ranger who organises a team of minders. They identify nesting areas throughout the Coromandel Peninsula and help protect them from the many dangers that threaten them. The dedication and commitment of the minders on the beaches – some in remote areas - is vital to the success of the programme. The funding also pays for a predator control programme and public education, including signage at beaches. This helps toraise awareness about the presence of nests and the need to protect them from beachgoers, domestic pets, predators and vehicles.

During the 2009 - 2010 season, throughout all the known nesting sites on Coromandel beaches, there were 100 fledged chicks and four hatchings aged up to six weeks old that are currently yet to fledge. An increase in breeding pairs was reported at an increased number of sites. Productivity value (the average number of chicks fledged per breeding pair) is higher than the previous few seasons.

Management of dotterel numbers is considered effective if productivity values are greater than 0.5 for three consecutive years or longer.* This season is the seventh consecutive season where productivity greater than 0.5 has been achieved.

Predators

To keep predators under control trapping was undertaken at most beaches on the east coast from Waikawau to Whangamata from mid- August to mid-February. This was carried out by DOC ranger Andy Wills and a number of volunteers.

This season saw an increased number of predators caught over the previous season for all species targeted. Two adult dotterels were killed during egg incubation. Cats or stoats were the suspected attackers. The main predator species is the hedgehog; 170 hedgehogs were caught in traps throughout the season. Other culprits are rats, stoats, feral cats and weasels.

 

Susan Bryant is DOC's NZ Dotterel Watch Ranger. Susan writes:

"Breeding has drawn to a close and NZ Dotterels have departed to post breeding flock sites around the peninsula. The key post breeding flock sites are those that regularly hold more than 30 birds. These are Colville, Matarangi, Pauanui and Opoutere. Slightly fewer gather at Whangamata, Onemana and Coromandel.

During this period of gathering, young birds reaching breeding maturity will attempt to find a mate, and those birds having lost a mate during the breeding season will attempt to find a new partner. Increasing numbers of NZ Dotterel may be seen on the beaches as the birds move towards these flocking areas.

Early January saw the beginning of increased numbers roosting at high tide on Matarangi Beach. This number has increased to a current population of around 100.

Most adult NZ Dotterel are relatively long lived with an average life expectancy of 14 years, representing 12 breeding seasons. One dotterel chick from Whangamata, found to have a broken wing and unable to fledge was taken to Auckland Zoo and will now be part of their shorebird display.

A reminder: if anyone finds what they believe is a dead NZ Dotterel on a beach, please collect it in a plastic bag, document the date and place it was found and ring DOC."

 

Fantail Garden

Whatever it takes ...

It's a motto they use at Pathways Health and put into practice at Fantail Garden.

Pathways creates mental health and wellness opportunities that enable people to live their dreams. The gardens in Waihi were set up as a pre-employment project ten years ago.

They moved to the current site on Newmont Waihi Gold land at Boyd Road six years ago and became Fantail Garden. All the produce from the gardens is certified organic and there is a large variety of vegetables, fruit and flowers grown there.

The busy summer harvest is almost over now and the gardens are being made ready for the next season's crops. Project co-ordinator Jenny Parks is justifiably proud of the project she helps to run and the benefits it provides to members of the community who need a helping hand as they recover from mental illness.

 

"This project provides spiritual, emotional and physical support," says Jenny. "People come here to learn skills required to re-enter the work force, skills required to grow an organic garden and people benefit from lots of healthy vegetables while socialising with others. Those who attend benefit from, and value the gardens as a therapeutic, organic environment."

As well as making company land available, NWG assists the project by supplying tools and materials and, recently, repairs to the tunnel house (pictured above).

Coming Up

On Wednesday evening 24 March TV3 is planning to include a segment about Waihi on its Sixty Minutes programme screening at 7.30pm.

This is hot on the heels of TV One's Close Up programme last Thursday evening (18 March). Both of these programmes were spawned by the interest created by the debate over the Crown Minerals Act's Schedule 4 land and the impending release of the government's public discussion document.

On a completely different topic, Waihi and mining will again be the focus of another television feature. A Maori Television film crew were in town a few weeks ago to prepare a story about the New Zealand Tunnelling Company, on active service during World War One in Arras, France. The documentary will screen on ANZAC Day, Sunday 25 April.

The 23rd annual Miners' Reunion is to take place on Friday 9 April. This is for the folk who were associated with the pre-1952 Martha Mine and Victoria Battery.
