We have worked with Melbourne Water to collate their collection of macroinvertebrate assemblage records from streams of the Greater Melbourne region over the last 25 years into a database, and have made it available and searchable on an open-access web interface (https://tools.thewerg.unimelb.edu.au/mwbugs/). This rich resource of biological information has been…
Sure, this might be a bit niche, but in preparation for the imminent release of a portal for Melbourne Water’s stream macroinvertebrate database, I’ve created a data-entry app for compiling macroinvertebrate assemblage data into a table that is suitable for entry into the database (and suitable for analysis on its…
The desktop box that is urbanstreams.net is getting old. We are in the process of migrating the contents of this site to a more stable and secure location. The move has begun with our apps. Because he who is last will be first, the most recent app is the first…
It’s been a long time between posts (I’ve been away for much of the year: more on that later). This return to the blog is to announce the completion of the Melbourne Water Stream Network v1.0, now available at tools.thewerg.unimelb.edu.au/mwstr/*. The stream network is a spatial database, comprising a stream…
I’ve added another entry to my raingarden diary today, primarily spurred by (an old picture of) the raingarden featuring on the front cover of the current issue of ReNew magazine. (I see that the issue includes an article by friend of urbanstreams.net, Peter Coombes, on the performance of the rainwater harvesting…
Biodiversity offsets are a popular policy tool to atone for the damage done by land development. Trouble is, they often don’t achieve their stated aims of ‘offsetting’ the development’s biodiversity losses with conservation gains elsewhere. The problem is amplified if the animals and plants you are trying to protect live…
I was asked to give a talk to a meeting at Environmental Justice Australia’s community forum for Rivers of the West last night. As usual, I banged on about the importance of stormwater retention and harvesting to protect rivers and streams, including in dry areas like the west of Melbourne. …
Our raingardens and tank have been operating for over three years now. I have been too busy to do the stocktake on performance that I have been intending to do for the last 6 months, but even without doing so, it is clear that the impressive growth of the grapevine…
Matt Burns of the WERG has developed a new tool that has joined the urbanstreams.net family. The Baseflow Estimator can help assess how much water should be flowing down any stream (or drain) across the Melbourne region. Matt explains… For undeveloped, unregulated catchments, very little rainfall becomes streamflow. For example…
