Thank you for having WSWA and Hawkesbury-Nepean Landcare Network come talk about Lantana and Threatened species.
This is made possible through the support of The NSW Landcare Enabling Program and our Local Landcare Coordinator.

With the warmer weatImage attachment

With the warmer weather WSWA staff are on the look out for aquatic weeds. The weed in the photo is Sagittaria platyphylla and can be found in drainage channel and shallow water bodies. It can spread quickly and impact water flow and habitat. Plants can be submersed and become difficult to control. However with the dry weather plants were accessible for treatment.
This plant must not be sold in NSW.
