The benefits of big snows

The Shore has seen another major snow event this year after not seeing any for two consecutive winters. The heavy snow will stick around for several days, as cold temperatures are in the forecast through Saturday.

Snow, and particularly heavy snows, yield tremendous ecological effects on the land and water. A heavy snowfall offers crucial ecological benefits that help maintain healthy ecosystems and support wildlife. As snow melts gradually, it replenishes soil moisture more effectively than rain, allowing water to seep deep into the ground and recharge groundwater supplies. This slow melting process helps reduce drought risks during the growing season.

Snow acts as a natural insulator, creating a protective blanket that maintains soil temperatures around 32°F. This protection shields plant roots, tree bases, and soil microorganisms from extreme cold and prevents frost heaving, which can damage plant roots. Winter crops like wheat and garlic particularly benefit from this natural cover. The snow also captures atmospheric nitrogen as it falls, which enriches the soil when it melts – a process that has earned snow the nickname “poor man’s fertilizer.”

The gradual snowmelt nourishes wetlands, something the Shore has in abundance, creating vital breeding grounds for shorebirds. Wildlife benefits in other ways too – snow provides cover for prey animals and creates warm spaces underneath where small mammals can safely forage. Extended snow cover can also help control pest populations by reducing harmful insects like ticks and aphids. Additionally, snow prevents soil erosion by protecting the ground from wind and water runoff, particularly benefiting agricultural fields and hilly areas.
