Eumarrah Hobart Natural & Organic Food are supporting the Derwent Estuary Program this September! By purchasing their 'flavour of the month' a portion of the proceeds will be dontated to the DEP to support our work in caring for the Timtumili Minanya/Derwent. All by eating caramel buckies! Yum!!

**SEPTEMBER 'FLAVOUR OF THE MONTH' - CARAMELISED BUCKIES**

Introducing our 'Flavour of the Month' - Mindful Foods Caramelised Buckies... on special with $10 OFF/kg! Clusters of caramelly goodness made in Byron Bay - activated, organic, vegan & gluten-free. 🧡

This month WE'RE DONATING 20% of the sales of Caramelised Buckies to the Derwent Estuary Program - a partnership working to protect and improve the health of the Derwent Estuary through science, monitoring and environmental projects. They focus on water quality, habitat and wildlife conservation, reducing pollution and litter, and helping the community understand and care for the estuary 💦

Caramelised Buckies are crunchy activated buckwheat kernels coated in a delicious selection of superfoods, such as maca and mesquite. Enjoy with milk (hot or cold), in trail mix, and great as a topper for yoghurt, desserts, ice-creams and smoothies.

Today we launched the 2025-26 Recreational Water Quality Report.

There are positive signs, with improved long-term water quality ratings at several Derwent beaches and bays. However, some results across the estuary show that work needs to continue to address stormwater pollution.

We're committed to working alongside councils, TasWater and the Tasmanian Government to improve water quality and protect the waterways our community values. See the new water quality ratings here: https://www.derwentestuary.org.au/beach-watch/

What’s changed beneath the Derwent Estuary over the past decade?

In 2024, the Derwent Estuary Program commissioned IMAS to revisit 27 intertidal and subtidal reef sites across the estuary, first surveyed in 2010. The new report compares the two surveys, revealing how fish, invertebrate and algal communities have changed over the last decade.

Key findings include:
🌿 Kelp expansion into the middle estuary and deeper waters, suggesting improvements in local water quality.
🐟 A significant decline in Bastard Trumpeter, potentially linked to increased recreational spearfishing pressure.
🦪 More Native Oysters, particularly in the upper Derwent Estuary, indicating positive changes for this important native species.
🌡️ Signs of warming waters, with range-extending species such as Mado Sweep and Pink Snapper observed in the estuary.

Read the full report on the Derwent Estuary Program website to learn more about how the estuary's reef ecosystems are changing over time. Visit https://www.derwentestuary.org.au/publications/

Wednesday was the official opening of the boardwalk and the milaythina rayakana Palawa cultural saltmarsh trail at the saltmarsh restoration at Windermere Bay. We celebrated with a community planting along with Glenorchy City Council. We had help from 22 people, who planted 300 plants that will buffer and stabilise the saltmarsh. Twelve months on from scraping, the saltmarsh is returning, along with fish and birds.

This project was funded by the Australian Government's Urban Rivers and Catchments Program, and we are so proud of the results!

FortySouth's Tasmanian-based writer Katherine Johnson has written a delightful article about the Ceramic Art Burrows for Hobart Little Penguins! You can read it at https://fortysouth.com.au/art-meets-science-in-the-service-of-little-penguins/. (You can also check out the beautiful images captured by Peter Whyte of the ceramic burrows made by ceramic artist Jane Bamford.)

If you'd like to hear more about the project, and see one of the ceramic burrows in person, head along to the free public talk which will be held at TMAG Royal Society Room on 23 April from 2pm to 4pm.
