This is a very exposed spot, with winds from the south and winds from the west.
The Acacia fimbriata split at a fork in the truck on a particularly gusty day so we lost half the tree. I cut off the side branch and the rest of the tree survived and now thrives.
Other plants in the photo Grevillea Canberra Gem, Westringia, Eremophila oppositifolia “Moonlight”
There is a birdbath (behind the Westringia) and some large rocks to stabilise the slope and slow water flow. Being undisturbed it is home to some Blue Tongue lizards. Also very popular with the Brown Honeyeaters and Fairywrens.
