The past 3 weeks we have been learning all about leaves. We took a course at the Outdoor Discovery Center in Holland, Michigan with 2 naturalists to learn more about leaf and tree identification.
The first week we focused on flowers (aster family).
We started a journal y identifying parts of a flower and then headed out to the trails to collect finger size specimens. We found things like golden rod, New England Aster, Queen Ane’s Lace and much, much more! Back in the classroom, we taped the flower samples and added detailed information about their family and locations next to them to catalog everything we found. We also were given a guide booklet of the families of flowers and trees to keep, much to our delight! The next week was… Trees!
This was an interesting day. We learned about leaf types and took our knowledge along with an identification list on a tree scavenger hunt. We learned about the parts of a leaf like the midrib and the veins, alternating and opposite leaf patterns, lobes, teeth and what a whole leaf shape looked like. As a group we paired up to see if we could name the trees on the preserve. That is tricky business!!
The 3rd week, we focused on seeds and dispersal. Once we were out on the trail, we learned about milkweed, witch-hazel, dogweed. Once dogwood dries up, the seeds are projected out of their casing, shooting up to 5 feet in distance! If you are in a really quiet room, you can hear a very distinct popping sound when they erupt! Seeds can disperse via flight (think dandelions), water (think coconuts), poop (think berries) and attachment (think burrs). Often it is one of these methods of transport that aids in non-native plants becoming invasive like, Autumn Olive (aww, poor Olive).
We learned a lot! A funny thing about our particular group – they were obsessed with milkweed seeds and were throwing fistfuls of them everywhere to watch them fly. At least the Monarchs next year will appreciate their enthusiasm! Time for me to ‘leaf’ now. :0)
