| Special values | 7.8.3: Remnants on the Atherton Tablelands are of special historic significance as an indication of what the formerly extensive Mabi Forest was like. The Shipton's Flat example is naturally rare, and is of This RE is important tree kangaroo habitat. Threatened plant species include: Alectryon semicinereus, Alloxylon flammeum, Elaeocarpus coorangooloo, Firmiana papuana, Marsdenia straminea, Phyllanthera grayi and Breynia macrantha. Parsonsia wongabelensis is a highly restricted species. This RE along with 7.3.37 make up the "Mabi Forest" listed as "Critically Endangered" under the Environment Protection and Biodiversity Conservation Act 1999. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. Mosaic burning in surrounding fire-adapted ecosystems will minimise spread and severity of wildfire during severe weather events. ISSUES: Occasional hot fires in adjoining communities may be required to prevent expansion of rainforest elements. Edges are generally self-protecting but back burning from rainforest edges may be desirable. The occurrence of high biomass grasses in or adjacent to rainforest may detrimentally affect rainforest during fire events associated with dry weather. |
| Comments | 7.8.3: This RE together with the RE 7.3.37 is known locally on the Atherton Tablelands as "Mabi Forest" and in the Shipton's Flat area as "Jarrabina Forest". Some of the remnants are on soils of marginal agricultural potential (prairie soil types) due to presence of basalt boulders through the profile. Most notable for the relative absence of regional endemics. Predominantly the central and western Atherton Tablelands, and a very small patch at Shiptons Flat near Cooktown. Fragments which remain of this ecosystem on the Atherton Tablelands include remnants at Tolga (the "Tolga Scrub"), Wongabel State Forest, Yungaburra State Forest, Mt Quincan, Curtain Fig Forest Reserve and the Seven Sisters. In pre-clearing times the RE covered a large continuous area of the Atherton Tableland north and west of Malanda. A considerable proportion of this highly endangered ecosystem remains under freehold tenure, and is highly fragmented. Exotic smothering vines, such as Turbina corymbosa, are invading many remnants. 7.8.3a: This RE (together with RE 7.3.37) is known locally as "Mabi Forest" and is derived from the word "mabi" or "mapi" (which means Lumholtz's tree-kangaroo) used by the local Ngadjonji and Dulguburra Yidinji people. 7.8.3b: This RE is now mapped as 3.8.2d. This RE is locally described by Kuku Nyungkal people as "Jarrabina Forest" (Jarrabina, in the Kuku Nyungkal language, means Bennett's tree-kangaroo). |
1 Estimated extent is from version 13 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use. It is included in the regional ecosystem description database because the RE code may appear in older versions of RE mapping and the Vegetation Management regulation.
