Nature cares for itself. It is a cycle of regeneration. Stumps left by nature are completely different to stumps left my humans cutting down trees. This tall stump is fairly out of the open - not much vegetation around, and we couldn't spot any that should not have been in the area.
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. This one, however, you should NOT find along Humeburn Road:

Tiger Pear is an Opuntioid cacti that grows up to 60cm high. The stems are divided into cylindrical pads that are covered in very sharp, barbed spines. The stems are dark green with a purple or red tinge. The stems detach very easily and are readily transported by animals. The flowers of Tiger Pear are 6cm wide and yellow.
Dense infestations compete with native vegetation and pasture and may prevent access to water. The plant’s sharp spines can cause injury to native animals and livestock, which may lead to a reduction in productivity.
It occurs occasionally near Eulo.
