Do Leaves Decompose in Water? Understanding the Impact of Leaf Decomposition on Our Ecosystems

When it comes to dealing with fall leaves, many of us have our preferred methods for disposing of them. Whether you bag them, compost them, mulch them, or give them away, it's essential to keep leaves out of storm drains and our waterways. But why is this so crucial? In this article, we'll delve into the world of leaf decomposition, exploring how leaves affect our lakes, rivers, and ecosystems when they're not properly managed.

As leaves decompose, they release nutrients into the water, which can lead to an increase in algae growth. When those algae die, they sink to the bottom of the body of water and begin to decompose. This process removes oxygen from the water, making it difficult for fish and other aquatic life to thrive. In extreme cases, low oxygen levels can even cause mass fish kills.

Another concern is sedimentation. As leaves decompose, they release particles that settle at the bottom of the waterbody, obscuring its clarity and impeding the growth of aquatic plants. In some instances, this sedimentation can be so severe that it makes it impossible for certain plants to survive.

So, why do experts say that fall leaves are harmful to lakes? It's because as leaves decompose, they lower the amount of dissolved oxygen in the water. This reduction in oxygen levels can have devastating effects on aquatic life and even human health.

But how can we mitigate these issues? One crucial step is to keep our storm drains clear of leaves and other debris. When leaves blow into the streets, they often end up in storm drains, which can clog the system and cause flooding and other problems. By keeping our streets clean and clearing our storm drains regularly, we can prevent this from happening.

In addition to proper drainage management, composting is an effective way to deal with fall leaves. Composting requires a mix of green and brown materials, including leaves. Green materials like grass clippings, kitchen scraps, and fruit and vegetable peels decompose quickly and help speed up the process. Brown materials like dried leaves, straw, or shredded newspaper provide carbon and slow down the decomposition process.

When composting leaves, it's essential to remember a few key rules. Add green leaves in moderation, as they can create anaerobic conditions that inhibit decomposition. Red or yellow leaves should be added in small amounts, while brown leaves should be avoided altogether.

By understanding how leaves decompose and taking steps to manage them effectively, we can help protect our lakes, rivers, and ecosystems. Whether you compost, mulch, or bag your leaves, make sure to keep them out of storm drains and our waterways. Together, we can create a healthier environment for all.
