Native Plants
If you hike or garden near chaparral and oak woodlands in Southern California, knowing exactly where this itch-inducing native shrub has been spotted helps you keep your skin, and your dog's fur, out of it.
Someone out in Los Angeles County spotted Pacific poison oak, took a photo, and submitted it to iNaturalist, where other experts confirmed it really was that plant. This kind of crowdsourced record helps build an accurate picture of where poison oak grows so hikers, gardeners, and land managers can watch out for it.
Key Findings
Observation reached 'research-grade' status on iNaturalist, meaning the identification was confirmed by community consensus.
Location confirmed as Los Angeles County, US-CA, within the plant's known chaparral and woodland range.
Adds to the growing public dataset used to track poison oak distribution across California.
