Regional ecosystem details for 12.2.13

Regional ecosystem 12.2.13
Vegetation Management Act class Of concern
Wetlands Not a Wetland
Biodiversity status Endangered
Subregion 4, (9), (8)
Estimated extent1 Pre-clearing 400 ha; Remnant 2021 200 ha
Short description Open or dry heath on dunes and beaches
Structure code Open Heath
Description Open or dry heath. Characteristic shrubs include stunted Banksia aemula and Allocasuarina littoralis as well as Xanthorrhoea johnsonii, Leptospermum semibaccatum, Phebalium woombye, Dillwynia retorta and Caustis recurvata. Usually occurs on Pleistocene dunes and beach ridges. Not a Wetland. (BVG1M: 29a).
Supplementary description Bean et al. (1998), D12
Protected areas Naree Budjong Djara NP, Noosa NP, Great Sandy NP, Littabella NP
Special values 12.2.13: Habitat for threatened plant species including Allocasuarina emuina, Acacia attenuata, A. baueri subsp. baueri, Prasophyllum wallum and near threatened species including Macarthuria complanata.
Fire management guidelines SEASON: Late summer to winter. INTENSITY: Moderate. INTERVAL: 8-15 years. INTERVAL_MIN: 8. INTERVAL_MAX: 15. STRATEGY: Aim for a burn mosaic of 40-60%. Do not re-light areas remaining unburnt after a planned burn. Burn in association with surrounding ecosystems. ISSUES: Often contains obligate seed regenerating species and as such, the application of frequent fire may reduce species richness if the intervals between fire are not sufficient for plants to produce seed. Acacia attenuata requires fire for seed germination, produces seed from 2-3 years of age and may senesce from 5-10 years. Too frequent a fire frequency may result in loss of terrestrial, threatened ground orchids and net loss of nutrients over time from an already nutrient poor system.
Comments 12.2.13: Floristically rich. Naturally restricted to Noosa, Minjerribah\North Stradbroke Is and one location just south of the Elliott River. Subject to sand mining.
