Sugarbush Management 1

By: uvmext

Sugar makers rely on healthy, abundant maple trees to provide sap each spring. Taken together a group of maple trees managed for sap collection is called a sugarbush. Developing a healthy, productive sugarbush takes time and effort. Forests are hi...

Shade Tolerance 2

By: uvmext

As trees form, the size and shape of its stem and crown, will be impacted by living in a low light environment such as the forest's understory. So-called suppressed trees are able to capture just enough sun to survive. Sugar maples growing in the ...
