Biodiversity Strategy - Gosford City Council - NSW Government

Recommendations from Rainforest Mapping Project
Recommendations
1. Provide a 50 metre buffer for conservation 7(a) zoned lands where they adjoin
rainforest.
2. Where residential subdivision is planned for catchments that contain rainforest
provide a 100 metre buffer to Conservation 7(a) lands.
3. The presence of Eucalyptus saligna and Syncarpia glomulifera along edges of
drainage line should trigger a further search for Gully Rainforest within drainage line.
4. Remnant Littoral Rainforest at Heazlett Park Avoca may qualify under State
Environmental Planning Policy No 19.
5. Dry Rainforests at Peats Ridge Quarry and Glenworth Valley not mapped.
6. Separate zoning established for rainforest with appropriate zoning.
7. List of common indicator species (Included in Appendices).
8. Gullies and other areas with very large Small-leaved Figs Ficus oblique should be
given 'Special Conservation Protection'because of significant for suite of threatened
species.
9. All rainforest maps to be added to Council's fire Planning Maps.
10. GCC and NPWS to coordinate a plan to establish a reserve for the protection of
Prostanthera askania and Silver Aspen Archonychia wilcoxiana on Lot 2 DP 605505
and Lt 2 DP 605752.
11. Develop a conservation plan in co-ordination with Wyong Council's Conservation
Plan to protect large P. askania population at Dog Trap Gully in vicinity of Lots2, 3
and 5 DP 239201 and Lot 14 DP 261303.
12. All Das involving rainforest should include targeted search for threatened fauna
species.
13. Results of the survey re weed infestation
14. Study referred to Heritage Committee for comment regarding 'old road located at
Taylors.

Terrestrial Flora
Diversity of Gosford Flora
The richness of terrestrial flora found in Gosford City reflects the diversity of ecosystems found
in the area as well as the LGAs location on the northern edge of the Sydney Basin with its richly
diverse Hawkesbury Sandstone vegetation. As part of the development of the Gosford
Biodiversity Strategy, a list has been compiled of all flora taxa likely to be found in Gosford City
(see Appendix 2 and Table 5.12 for a summary). This list is derived from DEC Atlas records,
specific studies and a database provided by the Society for Growing Australian Plants. This list
is considered to be a starting point only for data collection on known species and it is
recommended that it be reviewed, updated and revised as new information becomes available.
Of the total number of approximately 1400 plant species, at least 330 are introduced and likely
or known to be environmental weeds in bushland areas. Of the 1080 or so native plant species,
eight are considered to be endangered and thirteen are considered to be vulnerable at state
level (see below in Section 5.3.2. Plants such as Prostanthera junonis (Somersby Mintbush)
and P. askania (Tranquillity Mintbush) are only known to occur naturally (i.e. to be endemic) in
the Gosford and Wyong local government areas.
