Leaf Experiences


By Ranger Steve Mueller

 

The best learning is a family experience with fun. I was raking leaves and thought about my girls helping or thinking they were helping. Then I thought about when I helped my dad rake leaves or thought I was helping. What I remember best from both experiences is that I jumped into the pile of leaves and buried myself and my girls jumped into the leaf pile and buried themselves.

A difference in our experiences was what happened to leaves—Earth Stewardship. In the 1950’s people up and down the block raked leaves into the road and burned them. My girls learned leaves make good compost and should not be burned. As mulch they decay and release nutrients into the soil or garden rather than into the air. We used leaves to spread on trails at Ody Brook to prevent dirt from getting in the soles of shoes.

A great experience helps kids observe the intricate natural world. They see details and gain basic knowledge, comprehend what they experience, apply experiences to life at home and in the community, analyze what is best, synthesize what they experienced to use for new unrelated purposes, and then evaluate the value.

The experience allows discovery. I did a leaf activity with students when I was classroom teacher and at the Howard Christensen Nature Center. In fall we found a sugar maple and each student collected ten leaves and then we found a silver maple and collected ten more leaves.

In the process the students learned to distinguish leaf similarities and differences for the two species. Learning more about adaptations for the species took us deeper into reasoning and mental development. Students compared the amount of substance in the two kinds of leaves to discover that silver maple leaves were lighter with less substance. They curled and shrivel more than the heavier sturdy sugar maple leaves. We weighed the leaves and found sugar maple leaves were heavier.

I shared that sugar maple leaves do not remove most of the nutrients from the leaves but allow nutrients to fall to ground in the leaf, where they rot under the tree to release nutrients for the tree’s use in spring. Silver maples ship a greater proportion of nutrients to the roots with the sap, and store it until spring for new growth. Both species have unique nature niche strategies for recycling nutrients. Silver maples are floodplain trees and their leaves wash away with spring flooding so nutrients would be lost if dropped with leaves. Sugar Maples are upland plants and their leaves stay near the tree and release nutrients to their own roots.

My dad, like most other dads, did not realize that releasing nutrients into the air by burning leaves contributes to air pollution and increased atmospheric carbon. I like fires and “some-mores” so we burn branches cleared during trail maintenance and make our “some-more” treats. We allow many to decay in the woods to replenish soil health. Most nutrients are in the small branches that decay rapidly so we leave those in the woods and burn some larger branches. We use large branches for brush pile construction for bird and mammal shelters.

Create family experiences and build relationships. Our kids are grown but I still desire help with projects at Ody Brook. I can use the help but more importantly I think it continues to build our relationship. Of course, their lives are full and busy but sometimes we still build relationships working together outdoors.
