This Fall, remember to leave the leaves on the ground.
Jessica Ordóñez-Lancet submitted the following report from the National Wildlife Federation:
“With the arrival of Fall, the National Wildlife Federation wants to remind you to put your rake and blower away and leave the leaves on the ground as nature intended. Raking up fallen leaves and sending them to a landfill in bags is the norm for most American families during the Fall. However, these actions not only harm the environment and wildlife habitat, but rob your garden of precious nutrients.
‘“Leaves form a natural mulch that helps suppress weeds and fertilizes the soil as it breaks down. Why spend money on mulch and fertilizer when you can make your own? Turning leaves into solid waste is, well, wasteful,’ said National Wildlife Federation Naturalist David Mizejewski. ‘Removing leaves eliminates vital wildlife habitat. Critters ranging from turtles and toads to songbirds, mammals, and invertebrates, rely on leaf litter for food, shelter, and nesting material. Many moth and butterfly caterpillars make nests over Winter in fallen leaves before emerging in Spring.
‘“Sending organic matter such as leaves to the landfill causes the release of greenhouse gases that contribute to climate change. Best of all, the less time you spend removing leaves, the more time you’ll have to enjoy the gorgeous Fall weather and the wildlife that visits your garden.’
“The solution: Let leaves stay where they fall. Wherever possible, let fallen leaves break down naturally, which helps improve the soil and provides countless wildlife species with habitat. Although leaves will smother your lawn, consider replacing lawn areas with planting beds, filled with native plants and mulched with fallen leaves. If you must remove leaves, use them as mulch in your existing garden beds or compost them on site rather than throwing them away.
‘“It’s that time of year again. Let fallen leaves stay on your property. The air turns crisp, the leaves turn red and gold and homeowners turn to the annual chore known as ‘Fall garden cleanup’, including disposal of those leaves after they fall to the ground,
“Traditionally, leaf removal has entailed three steps: Rake leaves, or blast them with a blower, into piles, transfer the piles to bags and place the bags to be hauled off to a landfill. Yet, increasingly, conservationists say these actions not only harm the environment, but rob your garden of nutrients while destroying wildlife habitat.’
‘“According to the U.S. Environmental Protection Agency (EPA), leaves and other yard debris account for more than 13% of the Nation’s solid waste, a whopping 33 Million tons a year. Without enough oxygen to decompose, this organic matter releases the greenhouse gas methane, said Joe Lamp’l, author of The Green Gardener’s Guide. In fact, solid-waste landfills are the largest U.S. source of man-made methane, and that’s aside from the carbon dioxide generated by gas-powered blowers and trucks used in leaf disposal.
