High numbers of endemic plant species. Large numbers of near threatened butterfly species. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: No deliberate fire management required within this unit. Undertake fuel reduction burns in surrounding vegetation utilising multiple small fires throughout the appropriate season to manage biodiversity values and to limit the extent and reduce risks of wildfire. ISSUES: Fire sensitive vegetation type. |
| Comments | 3.3.1: RE 3.3.2 was amalgamated into this RE. Claudie, Normanby and Laura Rivers and Torres Strait. 3.3.1a: Is differentiated from similar semi-decidous notophyll vine forest in southern Cape York Peninsula (3.3.1b) by geographic distribution as well as higher abundance of climbing palms, feather palms and pandans, climbing ferns, epiphytes and hemi-epiphytes. 3.3.1 is also in the higher rainfall zone of the northern CYP than 3.3.1b. Occurs in northern and north-eastern Cape York Peninsula. 3.3.1b: The cabbage palm Corypha utan is a distinctive component of this subunit along the Laura river. This unit has floristic affinities with the northern parts of the Wet Tropics. South-eastern Cape York Peninsula. Senna siamea, an introduced tree species has become naturalised around old Laura and is spreading downstream along the Laura River. A large number of naturalised weeds are present in the dense ground layer that occurs where the canopy is sparse, including Achyranthes aspera, Mesosphaerum suaveolens, Ipomoea quamoclit, Physalis minima and Synedrella nodiflora. 3.3.1c: Torres Strait. Exotic species such as *Cocos nucifera (coconut palm) and *Mangifera indica (mango) are naturalised in this community. 3.3.1d: Was previously mapped as 3.3.1x1. Well developed forests. Downstream this unit merges into 3.3.4. This vegetation community is not mapped and included in areas mapped as 3.3.1a. Between Cooktown and Mt. Webb national park and near Lockhardt River. 3.3.1x1: Between Cooktown and Mt. Webb national park and small areas on Torres Strait islands. |
1 Estimated extent is from version 13.1 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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
