Flora & Fauna Survey & Ecological Assessments – 35 Water Street Wahroonga
Development Zone. Records by UBMC in 2006 noted these species as new plantings in what had been an
open grassy area south of the Core BGHF Habitat area.
A young Rusty Fig (Ficus rubiginosa) was observed growing as an epiphyte on a large Eucalyptus saligna at
the Young Street fence. One planted tree, a Small-leaved Tuckeroo* (Cupaniopsis parvifolia), although a
non-indigenous native species, was considered to be a significant planting owing to its general rarity in
landscape works and relatively large size and maturity.
Potential Impacts on BGHF for Lot 3: Lot 3 has 572 sq metres of BGHF, of which 77 sq metres (23 sq metres
building and 54 metres driveway) or ~13.5% would potentially be affected
AREA 2 – POTENTIAL NEW LOT 4
i) Development Zone (Transect 4w - Appendix 2)
Location: western section of potential Lot 4, as shown on Figure 1.3. In Appendix 2, the species list for this
site was marked as “4w”
Vegetation Type: Open (introduced) grassland with tree and shrub plantings
Condition of Vegetation: estimated to be: a-100/a-90/a-90/50%
Description: Lot 4 is downslope and south of potential Lot 3. It contained trees and scrub-type vegetation
throughout much of the Lot; however a cleared area occurs at its western end. In common with the area
potentially Lot 3, it was previously maintained as mown lawn and contained a grassy ground cover, now
mainly composed of Stenotaphrum secundatum*, Anthoxanthum odoratum* and Microlaena stipoides.
Exotics are rapidly colonising the area; with Plantago lanceolata*, Hypochaeris radicata* and Fireweed*
(Senecio madagascariensis) occurring in the more open areas, and Ligustrum spp*, Olea europaea subsp
cuspidata*, Ochna serrulata*, Hedera helix* and Asparagus aethiopicus* occurring in the more shady
locations.
Part of this area at the boundary with proposed Lot 3 contained a small Pittosporum undulatum 10 and a large
Irish Strawberry tree* (Abutus unedo).
No threatened or otherwise significant naturally-occurring (native) species occurred.
Ii) Non-development Zone (Transect 4e – see Appendix 2)
Location: eastern section of potential Lot 4, as shown on Figure 1.3. In Appendix 2, the species list for this
site was marked “4e”.
Vegetation Type: Open (introduced) grassland with tree and shrub plantings, merging into mapped BGHF
Habitat area (see Figure 1.3)
Condition of Vegetation: estimated to be: 0/90/90/70.
10 NOTE: Pittosporum undulatum is a small native tree which seeds profusely and establishes in bushland in the absence of fire.
Pittosporum is very common in the garden, and it has invaded the garden beds, paving and other structures such as the croquet lawn
and former children’s play area.
