Short description Corymbia tessellaris woodland on flat coastal dunes
Structure code Woodland
Description Corymbia tessellaris woodland, with occasional C. clarksoniana and Melaleuca viridiflora. Other associated species include Acacia crassicarpa, Pandanus spiralis and Acacia spp. The ground layer is generally grassy and includes species such as Heteropogon contortus and various forbs. Occurs on flat Quaternary coastal dunes. Not a Wetland. (BVG1M: 28b).

Fire management guidelines SEASON: Early dry season when there is good soil moisture, with some later fires in the early storm season or after good spring rains. INTENSITY: Primarily low to moderate, with occasional high intensity fires. INTERVAL: Typically 2 - 7 years, with some areas longer unburnt. INTERVAL_MIN: 2. INTERVAL_MAX: 7. STRATEGY: A predominance of early dry season fires is recommended, although there is value in occasional late dry season fires, or storm burns, over small areas. Burning should begin very soon after the wet season, to secure boundaries and adjacent fire-sensitive vegetation. Subsequent repeat ignitions can be used within the same section of land weeks or months after the boundaries have been secured by early burning, to produce a mixture of burnt areas with multiple ignition dates. Use topographical features to ignite areas as soon as they dry out. This will create a mosaic of areas that were burnt at different dates and unburnt sections within the same area of woodland. Burn away from riparian communities, which can be critical habitat for some species. Approximately 25% of the grassy woodlands within a landscape should receive patchy fires in most years. ISSUES: These woodlands have a diverse native grass and herb layer that is maintained and promoted by regular fire. Burning that starts immediately after the wet season, with follow up small fires ignited progressively over multiple dates can increase the availability of grass and herb seed, which is a critical food source for many birds and small mammals. Recently burnt grass clumps tend to produce more seed than unburnt clumps and the earlier burnt grass usually seeds earlier than later burnt grass. Maintaining a fire mosaic will help ensure protection of habitat and mitigate against wildfires. Low to moderate intensity burns with good soil moisture minimise the risk of losing hollow trees. An occasional late season burn will promote grasses and legumes. Ensure a diverse grass layer, hollow-bearing trees and vegetation structure are maintained.
Comments 11.2.1: Prone to weed invasion particularly by *Cryptostegia grandiflora (rubber vine) and *Lantana camara.
