We all know animals have various ways of dealing with winter. Some hibernate; some stay active under the snow. Much the same is true for seeds and plants. It’s called dormancy and it has a lot to do with chemical changes, both in the plants and in the rodents that eat the plants. WTIP’s Jay Andersen spoke with a local phenologist about the dormant plant world under the snow.

While most of us are skiing, snowmobiling and snowshoeing on top of the snow, there’s a whole world of activity under our feet. This is the subnivean environment. Small rodents and some insects live in this very special place – and the snow below can be a lot different from the snow on top.  Jay Andersen spoke with a local phenologist Chel Anderson about the mysteries and activities of the subnivean world.
