The flora and vegetation of the four high domes of Mt Tarawera; Ruawahia, Tarawera, Wahanga and Plateau. are described, and successional rates and trends determined at some sites by comparing 1964 and present-day photographs and records. Although below the regional tree limit, the dome tops are dominated by scattered low shrubs, herbs, grasses, mosses and lichens. With increasing distance from the 1886 eruption craters vegetation com- plexity and rates of succession increase. Plateau dome vegetation is successionally the most advanced.
