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.
