Control of Alien Invasive Species

Another ongoing project on is related to the control of alien invasive plant species. Amongst the more problematic and very invasive ones, and that the Park has worked on, are the Century Plant (Agave americana), Sisal Agave (Agave sisalana), Fountain Grass (Pennisetum spp.), Giant Reed (Arundo donax), Hottentot Fig (Carpobrotus edulis), Blue Leaved Acacia (Acacia Saligna) and Prickly Pear (Opuntia ficus-indica).

Large patches of Agave americana were removed from Naħħalija and the Ranges, using mechanical means. Several mats of Carpobrotus were removed manually from the sand dune at Ramla tal-Mixquqa, as part of the rehabilitation of the sand dune habitat.

Other alien species removed were Acacia trees. No chemicals were used in removing the alien species. The control of alien invasive plant species is usually foollowed up through regular monitoring and interventions where required.
