orange hawkweed (Pilosella aurantiaca) observed in Kodiak Island County, US-AK, US

Invasive Species
Orange hawkweed spreads aggressively through underground runners and airborne seeds, and once it colonizes a meadow or roadside it can crowd out the native wildflowers that pollinators and ground-nesting birds depend on.
Orange hawkweed is a bright-orange flowering plant originally from Europe that has been spreading across North America for over a century. It was spotted and confirmed on Kodiak Island in Alaska, which sits off the southern Alaska coast. This kind of sighting matters because tracking where invasive plants show up helps land managers and naturalists respond before a small patch becomes a big problem.
Key Findings
A research-grade (community-verified) observation of orange hawkweed was recorded in Kodiak Island County, Alaska.
Orange hawkweed (Pilosella aurantiaca) is a non-native invasive species in North America, native to central and southern Europe.
Kodiak Island represents a remote island ecosystem where invasive plant establishment can be particularly difficult to reverse once populations spread.

Pilosella aurantiaca is a perennial flowering plant in the family Asteraceae. It is native to mountainous regions of Europe and has been widely introduced elsewhere, where it is invasive in parts of North America, New Zealand, and Australia.
