In Horsnell Gully, our project sites have a particular focus of controlling a number of high priority weeds. Chincherinchee (Ornithogalum thyrsoides) is an introduced bulb weed found throughout the park. It forms dense infestations outcompeting native vegetation and can be found infesting high quality native vegetation areas. Due to it's toxic nature it threatens endangered species and their habitats.
Other weeds targeted in the project sites include boneseed, blackberry, watsonia, English broom and Montpellier broom. These weeds outcompete and smother native vegetation, their removal has aided in native species regenerating in cleared areas. Our work aims to contain and reduce the threats these weeds pose to the biodiversity of the park.
