Vegetation and flora of Lightheart Forest and adjacent reserves in the far north of Queensland’s Wet Tropics bioregion

The vegetation and flora of the Wet   Tropics bioregion north of Cape Tribulation has been reported on a regional   scale but detailed accounts have not been published. We report a description   of the vegetation, and floristic reconnaissance, of private and adjacent   reserved land 23 km south-south-east of Cooktown. The study area comprises   about 60 hectares, with low-lying coastal land, steep metasedimentary hills   and a rocky gorge with semi-permanent stream. The area mostly supports   closed-canopy forests; a portion of these have transitioned from eucalypt   forest or woodland to rainforest since the 1970s. We describe eight   vegetation types including four types of rainforest (Evergreen and   Semi-deciduous on slopes, Riparian/Alluvial and Littoral on the coastal flat),   Successional forest, Rocky gorge shrubland, Coastal strand and Mangroves).   Four vegetation types have conservation status under either or both federal   or state legislation; of particular note, Littoral rainforest identified in a   Council trust reserve is a Critically Endangered ecosystem under federal   legislation. The documented flora consists of 294 species, of which 85% are   trees, shrubs or climbers; over 90% are native to the area. The area received   a huge amount of rain following Tropical Cyclone Jasper, with local gauges   recording in excess of 3 m in three days, and we briefly report resultant   vegetation transitions. Vegetation of the area is dynamic at multiple time   scales.
