Pioneering species specialize in growth on previously disturbed land such as areas of clear cutting, damage by the elements or former agricultural land. These species are adapted well to nutrient depleted soils and colonize them more easily than other species. They are also known as successional species and make the soil more livable for species that are not good colonizers by putting nutrients back into the soil and providing shade for other plants.

Genus Cecropia: Cecropia trees are noted for their large palmately lobed leaves and tall thin trunks. They provide habitat for ants aiding in the diversity of species in successional forests.

Species Schefflera morototoni: Pavilla trees also have large palmate leaves, but that instead are compound. The trunks are also tall and thin. English common names for this plant are match-wood and mountain trumpet.
