Henderson is an elevated coralline limestone ( "makatea") island which rises as an isolated conical mound from a depth of about 3.5 km, and is presumably a reef-capped volcano.
In the makatea zones, however, most species are indigenous, and have been preserved because of the rough, almost inaccessible terrain.
The makatea islands have similar flora to Rarotonga, with differences related to their structurally variability (volcanic vs. makatea (limestone) substrates).
They have central volcanic hills surrounded by makatea: broad uplifted ancient coral reefs, as much as 2 km wide.
Vegetation in the volcanic inner hills of the makatea islands has been almost completely introduced, with the area mostly given over to cultivation.
Henderson Island is currently one of the most few relatively undisturbed makatea (raised limestone) islands in the world.
