Greetings! Glad you came. Thistles are a key food source for goldfinches and other birds as well as butterflies and
bees. If bill thistles and other non native ones are invasive and conquer native habitat, what
should we do to combat the non native ones and replace them with less invasive native ones? I've seen goldfinches and other birds feast on the seeds, as well as hummingbirds and other pollinators feasting on the nectar of the flowers at my community farm.
