Gayle Potter (80), who lives on Woolloomooloo Road, said she had taken it on herself to clean the area up for 15 years.
‘The creek is dry so I have been getting in among the bamboo and gums to remove the heavier rubbish,’ she said.
‘This morning I pulled out two car wheels with good tyres, a large sheet of corrugated iron and a long plank of wood and other rubbish.
‘Kids love to get in among the bush to make cubby houses in the trees or construct ‘bridges’ across the creek.’
Ms Potter said eventually these projects were forgotten but the construction materials used by the children remained.
She said people also used the area to take short cuts and left cans, bottles and food wrappings on the path.
‘But the worst offenders are local residents who dump unwanted goods like car and trailer waste, old lounge suites, car engines and old chassis,’ she said.
Ms Potter said she had contacted the Mundaring Shire to collect the piles she had made after her clean up.
