The 2021 Braided Rivers seminar will be held at Lincoln University Wednesday 14 July. The programme is currently being planned so the booking page looks a bit thin at the moment, but I encourage you to book early as, aside from Covid, these FREE events have historically been booked out and waitlisted. You can always cancel, and we always require you to confirm your attendance a week or so before the event.
In other news, I\’m delighted to announce that ECan has just approved funding for the Climate and Nature project. The goal is to create an open network so that everyone can easily access the knowledge and material resources needed to become climate-resilient. Not by buying electric cars, building dams and seawalls, and paying higher rates so our water is (more or less) drinkable, but by re-instating natural ecosystem services. The first few of what will be hundreds of projects demonstrating who is doing what, where, and how is now online thanks to seed funding from the Rata Foundation. We need YOUR help to expand this resource, so please let me know what biodiversity restoration projects you are involved with, even if you\’re not sure how this helps.
It\’s great to see the landscape-scale multi-agency protection project has been approved for the Rangitata River. The \’jobs for nature\’ project will include fencing 110 kilometres of riverbed and wetlands, planting 116,000 native plants on riparian margins, trapping sediment, and protecting braided river birds: wrybill, black-billed gull, black stilt/kaki, and black-fronted tern.
The BRaid website is continuously being updated with information and reports, not all of which are listed here as this newsletter is already long. If you\’re looking for something and don\’t have time to browse, don\’t forget you can use the internal search engine at the top and also bottom of each page, plus the sidebar in the main News pages.

Submit to the Climate Commission before March 28. Dozens of businesses and industries with a vested interest in maintaining business as usual and/or promoting ecosystem-destroying activities such bulldozing naturally regenerating forests that don\’t attract carbon credits to plant monoculture forestry which does, and expanding agriculture into rapidly dwindling braidplain ecosystems, are submitting. The same lack of economic incenctives applies to restoring wetlands, yet dried peatlands are responsible for up to 6% of agricultural emissions in New Zealand. Meanwhile, the world is on target to exceed 3°C but our post-Covid stimulus package committed $1.14 billion dollars to policies that support the fossil fuel economy. As Prof. Simon Lewis points out, creative carbon accounting is a recipe for disaster and Nature doesn\’t do bailouts.

- Using \’Linda\’ the scarecrow to scare off harriers raiding the black-billed gull colony trying to nest on the Ashley Rakahuri River.
- Unfortunately the story of \’Linda\’ was trumped when 4×4 drivers harassed and killing birds in the nesting colony. As much as I hate using social media to draw attention to the problem, it rapidly shifted from just-another-incident to newsworthy once our Facebook post reached 250,000 people. Read the full report here.
