| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. ISSUES: 8.12.14a-c: A geographically restricted ecosystem which with few exceptions is largely restricted to islands. Emphasis should be placed on the general principles of mosaic burning, and diversity of fire types. 8.12.14d, x2b: Emphasis should be placed on the general principles of mosaic burning, and diversity of fire types. |
| Comments | 8.12.14: Vegetation community 8.12.14x2b has been amalgamated into this RE. 8.12.14a: Can be similar to vegetation communities 8.12.6a and 8.12.6b which are also dominated by Eucalyptus drepanophylla, however 8.12.6a and 8.12.6b tend to be taller, with a more open canopy or sub-canopy and a more heavily grass dominated (instead of mixed sedge, grass and herb dominated) ground layer. Also 8.12.14a is only found on islands (or some headlands where it tends to be codominated by Lophostemon confertus or Acacia spirorbis subsp. solandri) whereas 8.12.6a and 8.12.6b are only found on the mainland. the vegetation community 8.12.12d may sometimes be similar but Corymbia clarksoniana (and/or other eucalypt species) will be a prominent feature in the canopy. The vegetation community 8.12.14d is very similar but occurs in subregions 4 and 5 only (8.12.14a is in subregions 1 and 2 only). The vegetation communities 8.12.14b and 8.12.14c are very closely related to 8.12.14a, but 8.12.14b is Acacia spirorbis subsp. solandri dominated and 8.12.14c is Lophostemon confertus dominated. Occurs on many islands from Gloucester Island to the Bedwell Island Group 40km east of Carmila. Widespread on some continental islands e.g. Broad Sound Island group. It occurs on the mainland at Double Bay, Shute Haven, Pinnacle Rock at Ball Bay, Cape Hillsborough and at The Leap north of Mackay. Most examples are in good condition probably due to the shallow soil/harsh environment which makes it difficult for weeds to establish. Many sites may not have been burnt for a long time. Weed species recorded include *Lantana camara, *Passiflora suberosa, *P. pallida, *Ageratum conyzoides subsp. conyzoides, *Stachytarpheta jamaicensis and *Triumfetta rhomboidea. 8.12.14b: The vegetation community 8.12.14d can be similar but occurs in subregions 4 and 5 only (8.12.14b is in subregions 1 and 2 only). The vegetation communities 8.12.14a and 8.12.14c are very closely related to 8.12.14b, but 8.12.14a is Eucalyptus spp. or Corymbia spp. dominated, and 8.12.14c is Lophostemon confertus dominated. Occurs on islands in subregions 1 and 2, from Hook Island in the Whitsunday group south to Keswick Island (30km north-east of Mackay). Also mapped in mainland coastal areas between Dingo Beach and Airlie Beach and on Round Head on Cape Conway. Most examples are in good condition probably due to the shallow soil/harsh environment which makes it difficult for weeds to establish. However some areas are infested with *Lantana camara. Other weeds commonly recorded include *Passiflora suberosa, *P. pallida, *P. pallida, *Ageratum conyzoides subsp. conyzoides, *Stachytarpheta jamaicensis and *Passiflora foetida. 8.12.14c: Lower, shrubbier examples of this vegetation community are similar to 8.12.29b, however in 8.12.29b Lophostemon confertus ranges from an associated to a co-dominant species, whereas in 8.12.14c Lophostemon confertus is strongly dominant. The vegetation community 8.12.14d and 8.12.29c can be similar but occur in subregions 4 and 5 only (8.12.14c is in subregions 1 and 2 only). The vegetation communities 8.12.14a and 8.12.14b are very closely related to 8.12.14c, but 8.12.14a is Eucalyptus spp. or Corymbia spp. dominated, and 8.12.14b is Acacia spirorbis subsp. solandri dominated. Occurs on several islands from Gloucester Island and Hayman Island south to Scawfell Island about 50km east-north-east of Mackay. Also mapped in the Gloucester Point area to the west of Hideaway Bay on the mainland. Most examples are in good condition probably due to the shallow soil/harsh environment which makes it difficult for weeds to establish. However some areas have *Lantana camara infestation. Other weeds commonly recorded include *Passiflora suberosa, *P. pallida, *Ageratum conyzoides subsp. conyzoides and *Triumfetta rhomboidea. 8.12.14d: Can be similar to vegetation communities 8.12.6a and 8.12.6b which are also dominated by Eucalyptus drepanophylla, however 8.12.6a and 8.12.6b tend to be taller, with a more open canopy or sub-canopy and a more heavily grass dominated (instead of mixed sedge, grass and herb dominated) ground layer. Also 8.12.14d is only found on islands and headlands in subregions 4 and 5 whereas 8.12.6a and 8.12.6b are only found on the mainland in subregions 1 to 3. The vegetation community 8.12.12d may sometimes be similar but Corymbia clarksoniana will be a prominent feature in the canopy. The vegetation community 8.12.14a is very similar but occurs in subregions 1 and 2 only (8.12.14d is in subregions 4 and 5 only). The vegetation communities 8.12.14b and 8.12.14c are very closely related to 8.12.14d, but 8.12.14b is Acacia spirorbis subsp. solandri dominated and 8.12.14c is Lophostemon confertus dominated (and only occurs in subregions 1 and 2). Occurs in the Shoalwater Bay region, on the mainland coast between Reef Point (north of the mouth of Island Head Creek ) and Cape Manifold. Also found on Turn Island in the Broad Sound area (30km north east of Clairview). Most examples are in good condition probably due to the shallow soil/harsh environment which makes it difficult for weeds to establish. However some areas are heavily infested with *Lantana camara. The weed *Passiflora suberosa, *P. pallida is also commonly recorded in this vegetation community. 8.12.14x2b: Distinguished from all other regional ecosystems by the presence of Corymbia xanthope. Mapped only on South Percy Island, but may also occur on other offshore islands. Has been heavily grazed by goats and is therefore probably suffering the effects of erosion, and the reduction in cover (and possible elimination) of the most palatable shrubs and ground layer species. Some weeds are present, including *Lantana camara and *Passiflora suberosa, *P. pallida. 8.12.14x2c: Distinguished from all other sclerophyll metamorphic (land zone 11) regional ecosystems by the low stature, and occurrence on headlands and islands in positions receiving high wind and salt-spray exposure. Occurs in subregions 4 and 5. Mapped at Sabina Point, Akens Island, Clara Island and Swan Island in Shoalwater Bay. Also found in coastal areas at Port Clinton and Freshwater Bay (north of Cape Manifold) and on the Keppel Isles. Usually reasonably good due to isolation and harsh rocky, wind and salt-exposed environment. Occasional weeds include *Lantana camara, *Passiflora suberosa, *P. pallida and *Melinis minutiflora. |
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.
