Nature Walk: White Pine

By Kerri Sorrell on March 25, 2013 in Blog


The approximate age of a conifer, such as this white pine, can be   determined by counting the number of whorls of branches from its base   to its crown.  In good growth years the spaces between the branch   whorls will be larger than in years of drought.  We have all seen the   rings recorded in a cross-section of a tree trunk.  A pencil-like core   can also be extracted with a coring tool and growth rings can be   analyzed without damaging the tree.

Sometimes weather and soil conditions can cause a tree to produce no rings or even multiple rings. How old are the trees around your home?

Because of trees’ long lifespan, Native Americans often bent them to create Trail Marker Trees to mark important places.
