Invasive Species
iNaturalistField peppergrass can quietly colonize the edges of your vegetable garden or lawn, competing with cultivated plants and spreading rapidly once established — knowing it's spreading in your region gives you a head start on managing it.
Field peppergrass is a small, weedy plant originally from Europe that has spread across much of North America. Someone spotted and documented it growing in Jefferson Township, Pennsylvania, and the sighting was verified as accurate by the iNaturalist community. These kinds of confirmed observations help scientists and land managers track where the plant is showing up and how far it's spreading.
