Silver Wattle Babies

Interesting mass germination of Silver Wattle (Acacia dealbata) recently. The ground in some parts is covered in a carpet with literally thousands of them.

Before they can sprout Wattles usually need a fire to melt their waxy seed coat.  No recent fires on these sites though so my theory is Cockatoos and Rosellas are doing the seed treatment by dropping partially chewed seeds from the trees while feeding. (I am open to other suggestions)

Lyrebirds are pretty active at the site and no doubt will scratch the vast majority of the new seedlings out of existence.

  1. I’ve observed it happening in many places along the Grand Ridge & Toora-Gunyah Roads, and I suspect the soil is just so wet that they are getting the good soaking they need (even though it is not the ‘hot water’ treatment that seed growers do!) particularly wherever the soil has been disturbed.

    1. Yes some consistent Autumn moisture would definitely have helped. Plenty of disturbance with Lyrebirds digging around in the leaf litter, could help with seed scarification too.
