Not So Sweet: Climate Change Means Slow-Growing Sugar Maples, Study Finds

It may seem paradoxical, but sugar maple trees need snow to stay warm and grow.

Each winter, a deep blanket of snow — 8 inches deep or more — covers about 65 percent of northeastern sugar maples. Without this insulating snow, the soil freezes deeper and longer, damaging the trees’ shallow roots.

A study published last week in Global Change Biology warns that without the snowpack, maple trees are projected to grow about 40 percent slower. As climate change reduces the amount of deep snow in New England, the study says this spells trouble for the trees — and for humans — as the trees not only give us syrup, but also eat up a chunk of carbon pollution.

“If temperatures keep increasing and the snowpack keeps shrinking, it suggests that our maple forests are going to not grow as much, and therefore not…
