The Department of Biodiversity, Conservation and Attractions' Parks and Wildlife Service and the City of Bunbury have urged the community to refrain from picking or trampling wildflowers.
City of Bunbury Mayor Gary Brennan is encouraging everyone to stick to the designated walk trails in all local parks and reserves, including Manea Park.
"The bushland at Manea Park is highly susceptible to dieback disease and it only takes a tiny amount of soil on the soles of shoes for the disease to spread," he said.
"I encourage visitors not only to stay on the designated paths, but also to use the shoe cleaning stations that are maintained by the Friends of Manea Park."
Parks and Wildlife Service regional parks coordinator Aminya Ennis said those who stray from the trails could crush the seedlings before they have had a chance to bloom.
"People travel from throughout the state to see and photograph spectacular native wildflowers and it's important that we don't disturb them so that everyone can have a chance to enjoy them," she said.
Under the Biodiversity Conservation Act 2016 and Biodiversity Conservation Regulations 2018, substantial penalties apply to people picking, cutting or pulling up native plants without a licence.
