Within the scope of action C8.1 “Control and eradication of invasive alien species (IAS) of flora in terrestrial habitats” of the LIFE IP AZORES NATURA project, the São Jorge Natural Park team carried out the removal of Arundo donax and Juncus acutus in the area surrounding the coastal lagoon of Fajã dos Cubres. Despite Juncus acutus being an autochthonous species, the population in Fajã dos Cubres has expanded excessively in recent years, thus competing with other native and endemic species in the area, making its control necessary.

The control of these two species was carried out on March 16 and 17 by 3 operational assistants, using a brushcutter. During the action, the workers took care to cut only the target species, leaving the endemic species intact. As has been observed previously, endemic species such as Solidago azorica establish themselves very well among the plants of Juncus acutus, after these have been cut down using brushcutters.
