An excellent turnout of 15 members and three visitors, who found us on Meetup, were greeted by Christine, Chris and Danielle from the Friends of Inglewood Triangle. Danielle explained how the triangle of bush was saved by accident when the Mt Lawley Golf Club who owned the land objected to Walter Road being put through the centre of the course. As a result the road was redirected leaving a small 1.8ha triangle bounded on the other two sides by Eighth Avenue and Hamer Parade. It is now an A Class reserve but not a Bush Forever site.
The upper and middle stories consist of a few eucalypt species (Marri, Jarrah, Coastal Blackbutt), four banksias (B. attenuata, B. grandis, B Ilicifolia and B. menziesii), two she-oaks (Allocasuarina fraseriana and A. humilis), Christmas trees and Balga.
Although it was still officially winter there was a considerable amount of colour in the understorey. Plants in flower included several wattles, Prickly Moses being particularly noticeable, three Hibbertia species, Daviesia physodes, Swan River Myrtle (Hypocalymma robustum), Pearl Flower (Conostephium pendulum), Devil’s Pins (Hovea pungens), Common Dampiera (Dampiera linearis), Prickly Conostylis (Conostylis aculeata) and Eremaea pauciflora which was just beginning to flower.
Although we saw a few cowslip orchids and donkey orchids, the spider and carousel orchids had barely begun to show their leaves. They appear to bloom much later in the Triangle than elsewhere.
Our guides also pointed out an area where they had planted the “pineapple bush”, Dasypogon bromeliifolius and another area they call the “scorpion patch” due to the numerous scorpions which inhabit the area.
The soil is derived from the Bassendean Sands and although not an obvious wet area there are at least 14 species of sedges, rushes and matt rushes. We learnt that many of these have only been apparent since 6 tonnes of veldt grass was removed. One of the most voluminous is Lyginia barbata which was in flower.
Very few insects were active and no fresh fungi, reptiles or amphibians were sighted although the site is known to be a refuge of the turtle frog (Myobatrachus gouldii). This species is one of the few frogs that skips the tadpole stage and can inhabit sandy areas without free standing water.
Although around 30 species of birds have been recorded in the reserve, Ian Abbott recorded only ten species during our walk: Weebill, Singing Honeyeater, White Ibis, Red Wattlebird, Silvereye, Rainbow Lorikeet, Striated Pardalote, White-cheeked Honeyeater, Black-faced Cuckoo-shrike and Western Raven. The Ibis, Lorikeet and Raven were seen flying overhead.
