Plant Galls

There are many ingenious creatures that have devised ways to trick plants into growing structures, called galls, which shelter and feed them. We’ll examine an amazing array of bizarre and beautiful galls as we learn the incredible life cycles of the gall makers. We'll be off trail, walking in grass for a short time. Distance: 2 miles.
