Patches of shrubs – mainly "Abutilon albescens", with "Melanthera biflora" (probably var. "canescens"), and the introduced wild poinsettia ("Euphorbia cyathophora") – are found here and there. Herbaceous plants are scarce here, mainly consisting of the grass "Stenotaphrum micranthum". The more open forest is composed of much the same plants, but the "Pisonia" does not predominate as much. A few "Pandanus tectorius" screwpines are also found here, and the understory is far more prominent. North of the "Pisonia" forest, a band of open shrubland with some trees extends from the resort to the island's eastern tip. Octopus bush ("Heliotropium foertherianum") and sea cabbage ("Scaevola taccada") form the major bush cover, while "Abutilon" and "Melanthera" are the characteristic ground plants. The trees here are mainly "Pandanus", but also "Celtis", the she-oak "Casuarina equisetifolia" ssp. "incana", "Ficus", bay cedar ("Suriana maritima"). Herbs—mainly the parasitic vine "Cassytha filiformis" as well as "Euphorbia tannensis" ssp. "eremophila" and grasses (mainly Pacific island thintail, "Lepturus repens" var. "subulatus") are abundant. The eastern end is marked by a similar habitat, with mainly "Casuarina, Scaevola" and "Heliotropium". This type of vegetation, with some "Pandanus" in between, extends along the southern and northern dune ridges. On the dune slopes, "Boerhavia repens", "Commicarpus chinensis" var. "chinensis" (or "Commicarpus australis"?), the searocket "Cakile edentula", yet another "Euphorbia" (probably "Euphorbia sparrmanii"), and kuroiwa grass ("Thuarea involuta") are common. East of the resort in the north-western part of Heron Island there is another type of forest, more open than the central wood. The main tree here is the manjack "Cordia subcordata" of which few are found elsewhere on Heron Island; "Pisonia" trees are present but not dominant.
