The natural process of trees shedding leaves in the fall is the most visible sign of trees preparing for winter dormancy. Leaves, however, are a major source pf the nutrient Phosphorus that is known to cause water quality issues in ponds and lakes. In fact, some studies show that nearly 60% of the annual phosphorous in urban water systems is from leaf litter! The good news is that this phosphorous can be mitigated through timely management of leaf litter.
Organic Matter In Water Systems
In addition to high levels of phosphorus, decomposing leaves release organic matter, which can cloud the water, making it murky and reducing light penetration. Reduced levels of sunlight limit aquatic plants’ ability to complete photosynthesis processes disrupting overall ecosystem balance.
Taking Action: 4 Ways You Can Keep Leaves Out Of Water Systems
Once the beauty of autumn trees has passed and the leaves have fallen to the ground, it is time to take action to keep leaves out of the water systems. Homeowners and communities have options for leaf management and disposal. Below are recommendations for managing autumn leaves so local ecosystems can be protected.
1. Mulch Your Leaves
Instead of raking and removing leaves from the landscape, use a mower to chop the leaves into small pieces. Chopped leaves can remain on a lawn without risking damage to the turf grass. Decomposing leaves add valuable nutrients to the lawn…think of it as free fertilizer.
2. Compost Your Leaves
Leaves are an excellent addition to a compost pile. By composting leaves, they are kept out of water systems while creating nutrient-rich compost that can be added to a garden. Dried leaves are brown materials in a compost pile, be sure to add green materials such as vegetable and fruit scraps, lawn clippings, and coffee grounds.
3. Bag & Dispose
Many municipalities offer leaf pick-up services in the fall. Typically, communities ask that leaves are collected in biodegradable bags and placed by the curb for easy pick up. Bagging and removing leaves from the landscape prevent them from washing into sewer systems or local streams. Contact your local municipality or visit their website to confirm dates and details.
4. Create Leaf Piles For Wildlife
Consider creating small leaf piles in your landscape for wildlife to use as shelter. Animals such as insects, birds, reptiles, and small mammals will use the habitat. Locate the piles in areas of the landscape that are incapable of washing away into water systems.
Preventing leaves from entering aquatic systems now will give you a great head start towards a healthy lake next spring!
