tree well
noun1
A hole or depression in the snow around the base of a tree caused by the tree's canopy preventing the accumulation of snow.
- First, tree wells are formed when the canopy of a tree prevents snow from accumulating at the base. Tree wells are noted by a deep ring of much shallower snow around the trunk, with walls of snow just beyond the protection of the canopy.2012, Eli Burakian, Basic Illustrated Snowshoeing, →ISBN, page 70:

- Townsend hare inhabit this area, particularly above the cabin, and a skier is likely to have one explode from a tree well and disappear into the whiteness as he skis by. Life is a constant bivouac for them -- they spend days huddled in tree wells during storms -- but I suspect they are as content and warm in their luxurious coats as we are in a cabin.2014, Patrick Armstrong, The Log of a Snow Survey, →ISBN:

A structure designed to protect the base and roots of a tree, typically used in an urban setting.
- A tree well is a great solution to a problem that often arises during excavation of a building, driveway, or road site. When excavated soil is carelessly mounded around the base of a tree, the tree gradually suffocates. Removing this soil from around the trunk and dry-stacking a tree well to retain the soil at a safe distance can save a tree's life.1998, David Reed, The Art and Craft of Stonescaping: Setting and Stacking Stone, →ISBN, page 71:
- Flat surface tree wells create a cleaner architectural effect where trees appear to grow directly out of the pavement.2007, Charles R. Hatch, Trees of the California Landscape, →ISBN:
