Hawkesbury - Nepean Catchment conservation kayaking to control Black Willows

Kayak trips along the Nepean, Warragamba, Wollondilly, Grose, Hawkesbury, Colo, MacDonald Rivers to treat black willows

Conservation Objective:

To protect rivers, creeks & swamps in the Greater Blue Mountains World Heritage Area (GBMWHA) and wetlands in the Hawkesbury floodplains by removing the remaining black willow trees from along the Hawkesbury Nepean River.

Black willows are a Weed of National Significance www.weeds.org.au/WONS/Willows They spread by windblown seed up to 60km & a single large tree can produce tens of thousands of seed that spread along rivers & creeks & into wetlands, Black Willows form monocultures, shading out Casuarinas, Bottle Brush, Tea Trees, Sandpaper figs, Lilly Pilli, Phragmities reeds and other native, seed bearing, plants that are the food source of many native birds.

What we do:

Willow Warriors organise a kayak trips along the Nepean River to poison Black Willows using bioactive glyphosate which is approved for use along waterways by volunteers . Volunteers & parks staff have already removed Black Willows from the Colo & Grose River sub-catchments that flow through the Greater Blue Mountains World Heritage Area . Hawkesbury River County Council, Willow Warriors, Wetlandcare Australia and Hawkesbury Nepean Catchment Management Authority are partners in a two year program to remove Black willows from the catchment.
