Molehill

A molehill is a small, conical mound of soil pushed up from underground by a mole. Molehills are a common sight in gardens, lawns, and fields, and are created as moles tunnel beneath the surface, creating extensive networks of runways.

Formation:

Molehills are formed when moles excavate soil while creating their tunnels. The excess soil is pushed upwards to the surface through vertical shafts. The size and number of molehills can vary depending on the species of mole, the soil type, and the extent of the tunnel system.

Impact and Management:

While generally harmless, molehills can be considered a nuisance to homeowners and gardeners. They can disrupt the smooth surface of lawns, damage plant roots if present in large quantities, and create uneven terrain.

Management of molehills often involves dispersing the soil back into the surrounding area. This can be done by raking or shoveling the soil back into the mole tunnels. More aggressive methods, such as trapping or using repellents, can be employed to control mole populations.

Ecological Role:

Despite being a nuisance to some, molehills can play a role in soil aeration and drainage. The tunnels created by moles can also provide pathways for plant roots and other organisms. The turned-over soil can also expose previously buried seeds to sunlight, potentially aiding in germination.
