Delaware state park will use cows to manage plants

    Looks like they’re onto something in Carlisle, Pa.

    Brandywine Creek State Park in Delaware will bring in the cows this summer to manage its invasive plant population. Two Belted Galloway cows will spend eight weeks crushing and munching on the invasive plants at the park, and scientists will monitor the change in vegetation.

    The cows will arrive once the $23,500 fence is in place later this month.
