		<description><![CDATA[If you can figure out the distance you need to be from the tree so that the reading equals the height (rather than doing the math) its a simple horizontal measurement to get the tree heights directly from the clinometer readings.  In the US we use the 66&#039; type so we only need to be 66&#039; from the tree and can measure the heights directly.

If you&#039;re stuck with metric ones, do the math ahead of time to see what the distance from the tree is to record direct heights from the clinometer. (Top shot minus bottom shot equals total height).

But you already probably knew that.]]></description>
