Moth Plant and Climbing Asparagus Control

25 volunteer hours of moth plant control have been carried out over the first 2 weeks of January. The aim is to remove the vines before the flowers turn into pods.
This weed is a massive problem in the Leigh area and we are working in conjunction with Coastal Care group and STAMP to control as many large infestations as possible.

We have also been continuing to clear climbing asparagus to ensure the seeds don’t get dispersed by birds.

Both of these strangling vines can cause canopy collapse of our precious forest remnants if left to take hold.

Recruitment of new members

We would like to welcome new participants to our trapping and baiting programme including Phillip Jones who has gone on a recruitment drive and spread the word about our restoration efforts. Thanks to Phillip’s input, our bait lines have been extended onto neighbouring properties on Cape Rodney point, with more possible recruits on the horizon.

We look forward to working with Phillip in 2024.

FORESHORE PLANTING – SUNDAY 10 DECEMBER 2023

Our final working bee for 2023 was held on Sunday, 10 December when, along with members of the Leigh community, we distributed mulch around the native plants which were planted in June this year on the foreshore near the bottom of Tenetahi Rd.

Thanks again to Kate McConnell and James Ross for selecting the plants and deciding on the planting layout. There has been an excellent survival rate due to Kate and James’s invaluable input and because we have had such a wet spring.

The area is going to look fabulous in a few years’ time, particularly with Kate’s plans to add further native shrubs.

Community working bees

A few small, impromptu community working bees have been held in recent weeks, during the brief periods of fine weather. On Monday, 9 October James Ross planted over 50 native plants at the bottom of the cliff near the Leigh wharf. Some weeding was also carried out including cutting down a few of the larger bone seed plants.

On Sunday, 22 October, Richard Henty from STAMP revisited the slopes above the harbour and carried out follow-up mothplant control. Richard’s and Chris Wadsworth’s efforts have made a huge difference to this area, and we expect to see less mothplant flowering during the summer months. We plan to employ an abseiler within the next few weeks to get rid of the pest plants from the higher slopes including a huge number of mothplant seedlings.

While carrying out weeding on the Leigh foreshore later that morning, I came across Cayan Streatfield from Cornwall who arrived on a bike carrying a pick fork and said ‘Hi, I’m Cayan and I’m here to help you!’ Little did he know what he was letting himself in for! Cayan is in New Zealand for the next year and plans to work as a WWOOFer around the country. He has proved to be very hard working and reliable and we have already lined up some other jobs for him.

September Update

While the wet weather might have hampered our pest plant control efforts, our trapping and baiting programme is in full swing. In the past year we have caught over 300 pest animals. Our pulse baiting programme is well underway and our dream of creating a pest-free peninsula is looking more achievable.

We are hopeful for some more fine weather so we can get stuck into climbing asparagus control along with managing other nasty weeds which have proliferated in the wet weather. A contractor is being employed to carry out some of this work.

Community Planting Day – Sunday 18 June

The Leigh Harbour Valley Society joined forces with members of the Leigh Community on Sunday, 18 June to plant over 600 plants provided by Auckland Council. A big thanks to Rose Crooks and Auckland Council for organising this event and to Kate McConnell and James Ross for selecting the plants and organising the planting plan. Thanks also to the enthusiastic volunteers (many of them members of Kate’s swimming group).

We also continued our weeding efforts at the bottom of Tenetahi Rd.

There is much more work to be done. The plants will need to be maintained to prevent kikuyu from strangling them and weeds in the surrounding area will have to be controlled; an ongoing battle!

Forest Bridge Trust Volunteer Open Day held in Matakana on Saturday, 24 June

Many thanks to Jo Evans and Sue Gibbings who represented the Leigh Harbour Valley Society at the Forest Bridge Trust Volunteer Open Day on Saturday, 24 June. Jo put together a fabulous poster promoting the efforts of the LHVS. He said it was well worthwhile being there and he received some very positive feedback but mainly from other stall holders because the weather was so lousy they didn’t get a large number of general public visitors. However, he had some interesting chats with groups he didn’t know were working in the area. It is always good to network.

Pest Animal Control

While the wet weather has not exactly been conducive to outdoor activities, we have not let it thwart our restoration efforts. There has been a real focus on pest animal activity and the tally since we started recording our catches more accurately in August 2022 is as follows:-

186 rats
11 possums
9 weasels
14 hedgehogs
Many mice

Along with trapping, we have been carrying out baiting and are now entering phase 4 of our pulse baiting programme.

Moth Plant Control

A big thank you to Chris Wadsworth who scaled the cliff above Leigh Harbour and collected 432 moth plant pods over two visits and removed many more vines. It was amazing how many passers-by stopped to ask if they were edible. While they do look a lot like choko, efforts were made to educate them about this nasty weed which is aptly named ‘ugly vine’.

On Sunday 4 June we had the pleasure of meeting Richard Henty, a science teacher and founder of STAMP (Society Totally Against Moth Plant). Many thanks to Kate McConnell for organizing this introduction. Richard spent 3 hours collecting another 450 – 500 pods (we gave up counting) and killing many more vines. This environmental warrior established STAMP after he first encountered moth plant on Motuihe Island 16 years ago. Along with help from his supporters, 18,000 moth plant locations are monitored around Auckland.

Climbing Asparagus Control

This nasty creeper is a real threat to our precious bush remnants and has taken off in some areas; probably helped by the wet weather. It tends to creep in from the edges of the bush blocks so is not always visible on formed tracks. Once again, we have been focusing on hand control. While this method is much slower, it does reduce the risk of collateral damage.
