CKISS has just launched our Crowdsorsa project for the Poison Hemlock Patrol project, where the public can get paid to remove Poison Hemlock- a poisonous invasive species that is present in the Creston region.
To identify this plant for removal, it’s important you know some lookalikes in our region (Native and Invasive).
Below you will find a comprehensive list and description of several plants that may easily be confused! As Poison Hemlock is in the carrot (Apiaceae) family, several species could easily be confused with it.
We have compiled a list with short descriptions of each plant- we encourage further research and reading if you are unsure- and recommend using a plant ID app (iNaturalist, PictureThis, Seek etc) to aid in your positive ID before removal of any plants!
*Remember to use proper PPE before any removal- only once you have completed the Crowdsorsa quiz should you go ahead with any treatment- and if you have further questions, please reach out to our team.
Several more species in the wider province may look similar, so please note the following list only includes those known to be in the Central Kootenay region, and does not apply to all of B.C. or the U.S.
Download the App and follow all instructions to remove Poison Hemlock, protect your community and make money while you do so!
