Three non-native pine species (Monterey pine, Mexican weeping pine, and maritime pine) are highly invasive. PC: Haleakalā NP.
Great volunteer event this Saturday, July 15, to help reduce the fire threat at Haleakala National Park.
From the Source:
"Three non-native pine species (Monterey pine, Mexican weeping pine, and maritime pine) are highly invasive. Rangers say they displace endemic and endangered species, change soil chemistry, and increase the potential for wildfire in habitats not adapted to fire. Park staff, partners, and volunteers periodically pull young pines to keep them from spreading throughout the park."
