Date Time Volunteers to nip Barrington Tops’ environmental weeds in bud National Parks and Wildlife Service are calling for all hands on deck this autumn to help remove environmental weeds from Barrington Tops National Park. National Parks and Wildlife Service (NPWS) Bush Regeneration and Volunteering Officer Boyd Carney said the Carters Road Wildfire, which impacted the southern end of the Barrington Plateau had cleared the way for environmental weeds, like Scotch Broom, to thrive. “More than 4000 hectares of the Gondwana Rainforests World Heritage Area on the Barrington Tops was impacted by the “Black Summer” bushfires. “With the fire damaging or destroying swathes of native vegetation, and stimulating seed germination, Scotch Broom has sprung up across the park, outcompeting our precious native plants in some areas.
