Parklands Albury Wodonga Rangers have been beavering away during the summer heat. Working along the Kiewa River, rangers utilised methods such as ringbarking to remove the very invasive Black Willow along the Kiewa River frontages.
An example of just how invasive this particular Willow species is. 5 Black Willow seedlings can multiply quickly becoming 50 the next summer and 500 the following. If left unchecked these populations will form monocultures that will choke out other plants; including our natives. This will reduce biodiversity along the river leading to population crashes of fish, birds, mammals and plants as Black Willows reduce the amount of food available in the complex ecosystem of the Kiewa.
To track this Parklands Albury Wodonga has conducted ground surveys to map out the physical location of these Black Willows to give insight into their colonisation patterns, physical distribution and which areas need more attention then others. See below for example:
This allows for land managers such as Parklands Albury Wodonga to make strategic decisions on how to tackle the Black Willow problem along the Kiewa.
Thank you to the North East Catchment Management Authority for their financial support through the Lower Kiewa River Stewardship Program.
