Late summer, while leaves are still green is a good time to assess the trees in your sugarbush. Weak or declining individuals will show areas of crown dieback. Trees with more than 75% dieback will likely not survive but are still competing for li...

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 ...

See back focal plane using telescope
The rear focal plane of the objective can be observed using a telescope insert into the eyepiece tube.
