                                                   itch pine grows on sandy barrens
                                              Por plains, and on gravelly soil of
                                              the uplands. It is quite common in the
                                              southern part of the state, on the sand
                                              plains near Brunswick and Oxford and
                                              on Mt. Desert Island.
                                                  Branches are horizontal, rigid,
                                              contorted and form an open crown.
                                              Pitch pine attains a diameter of 1–2
                                              feet, and a height of only 30–40 feet.
                                              The trunk tapers rapidly and generally
                                              is straight. Often the tree produces
                                              cones when small. It is the only native
                                              pine that will resprout when damaged
            Pitch pine wood is used for       by such factors as fire.
                                                  The bark is rough, even on young
            construction lumber, pulp and     stems and branches. On old trees, it is
            fire-starting “fat wood.”         irregularly divided into continuous
                                              broad flat ridges, and is deep gray or
                                              reddish-brown.
                                                  The leaves are in clusters of three,
                                              and are 3–5 inches long. They are dark
                                              yellow-green and stiff, standing at
                                              right angles to the branch.
                                                  The  cones require 2 years to
                                              mature, are 1½–3½ inches long, borne
