A Brisbane beekeeper has created a map for the public to locate African tulip trees in an attempt to weed out the plant, which kills native bees.
African tulip trees are toxic to native stingless bees and crowd out native vegetation.
Hobbyist beekeeper Phil Baskerville says you can find the map on Google Maps under 'African Tulip Tree' and wants people to drop a pin on every tree they identify.
Although Brisbane City Council stopped planting the trees 20 years ago, Mr Baskerville says they are "quite prevalent across fairly Brisbane old suburbs".
It is estimated there are about 2,000 older plants left.
The Department of Agriculture and Fisheries says the exotic tree is a significant weed across coastal Queensland which is "highly invasive, forming dense stands in gullies and along streams, crowding out native vegetation."
