Newsletter #98
Tēnā koutou katoa,
The annual Braided Rivers Seminar, will be held at Lincoln University Wednesday 09 July, 2025. As with 2024, we will be charging a moderate fee of $49.00 to help cover some of the costs. Lunch, morning, and afternoon teas are included, and there is plenty of free parking at the venue (map). I look forward to seeing you there.
Booking is essential as spaces are limited.
The following day, Thursday 10 July 2025, a Tarapirohe black-fronted tern workshop will be held at Environment Canterbury. The format and duration of this workshop is now being developed. If are interested in attending, please complete this online form as soon as possible.
Ngā mihi,
2024 winner of The Nature Photography Contest: Natural Landscape category:
This stunning image, without question the best braided river photo I’ve ever seen, was taken by Stuart Chape. Click here to be taken to the website and spend a few minutes enjoying more magical celebrations of that natural world. And while you’re browsing, take an extra few minutes to see the 2024 Bird Photographer of the Year.
Bird Surveys
- April 2024 – March 2025: Ashburton Rivermouth Bird Monitoring (PDF)
-
Please remember to send me your bird surveys when they are completed. These are added to each of the river pages on the website. This helps researchers and community groups to discern trends over time.
-
Please also send a copy to Miles Burford at ECan, as Miles is compiling an amazing database with the aim of eventually making it accessible online through Canterbury Maps.

- The Conversation: World-first analysis of seabirds who’ve eaten plastic reveals slow, insidious health impacts. “...young sable shearwaters (seabirds, Ardenna carneipes) less than 90 days old and appeared healthy. Despite their young age, the birds with plastic in their stomachs had signs or symptoms of neurodegenerative disease, as well as kidney and liver disease. It was absolutely shocking to see these signals of dementia because these birds are less than 100 days old, and they live up to 37 years.“

In response, The Waldrapp team has devised a new – and far longer – migratory route to Andalusia in Spain, a journey of 1615 miles (2600km) taking around 50 days.”

- Washington Post: Trump team cites wolf ‘de-extinction’ as it seeks to cut endangered species list.
As this misconception has profound implications for all endangered species, the facts are that Colossal DID NOT de-extinct Dire Wolves, which are giant extinct canids, not close relatives of grey wolves. They shared a common ancestor more than 5-million years ago, and are a remarkable example of convergent evolution. As Prof. Phil Seddon from Otago University points out: Colossal instead created genetically modified grey wolves. Prof. Tammy Steeves from the University of Canterbury has also set the record straight on Radio NZ. The magazine Chemical & Engineering News explains in a more in-depth article.
Research & Reports
- McCabe et al; The ecological benefits of more room for rivers, Nature Water, 21 March (Open access): “Floodplain river ecosystems have been extensively artificially constrained globally. As climate change heightens flood risks, the command-and-control approach to river flood management is beginning to make way for a paradigm shift towards ‘living with water’.”
- Brose et al; Embedding information flows within ecological networks. Nature Ecology & Evolution 04 April: “Traditionally, ecological network research has focused on interactions involving the flow of matter and energy, such as feeding or pollination. In nature, however, species also interact by intentionally or unintentionally exchanging information signals and cues that influence their behaviour and movement. Here we argue that this exchange of information between species constitutes an information network of nature—a crucial but largely neglected aspect of community organization.”
