This part of Humeburn Road is adjacent to the Paroo River Flood Plain and the next section of road has more trees than the country south towards the Adventurer Way and Cunnamulla. Tough old logs make good hiding spots too.
There are several invasive species you may come across while traveling along Humeburn Road. If you see any of these plants, please take Coordinates and report to Biosecurity Queensland on 13 25 23, within 24 hours. Here is one of them:

Parkinsonia is shrub or small tree that has distinctly green branches with sharp spines. Its leaves are typically 20-40cm long and flattened with small, oblong leaflets on each edge. The flowers contain 5 petals and are bright yellow, except for one that has an obvious orange spot. The seed pods are 5-10cm long.
Around Cunnamulla and Wyandra. Also Eulo to Yowah.
