The Briars Eastern Dwarf Galaxia Recovery Project - A 2026 Tidy Towns Environment Finalist!
Forty fish. Then more than four hundred, in a single breeding season.
That's the turnaround for the endangered Eastern Dwarf Galaxias at The Briars in Mount Martha, achieved not through a hatchery or captive breeding, but by changing how water moves through a wetland. Mornington Peninsula Shire's Destination Conservation and Wildlife Team, working with Ecology Australia through the Briars Arc Program, slowed water loss, built shallow vegetated breeding areas and improved connectivity across the site, aligning the wetland's flooding and drying cycles with what this short-lived fish actually needs to spawn successfully.
Because the Galaxias lives for only about a year, every single breeding season has to work. There's no margin for a bad year to be absorbed by older fish surviving to try again. That pressure shaped the whole approach: constant monitoring, adjustments made in response to what the data showed, not what the plan assumed.
The tenfold population jump wasn't the only outcome. Frogs and macroinvertebrates are benefiting from the same restored hydrology, evidence that fixing habitat for one vulnerable species often lifts an entire wetland.
The X-factor: no expensive infrastructure, just water managed the way nature intended, and a threatened species responding almost immediately once given the chance.
