1: Fires Defoliating Crowns. When the crown of a turpentine tree is defoliated
by fire, gum yield is reduced considerably. The leaves of a pine tree manufacture
the food which goes into the formation of wood and gum. Then this factory of leaves
is burned or otherwise destroyed while chipping continues uninterrupted, it takes
only a short time to deplete the tree's food reserves, after which gum or wood
formation must await the development of new leaves.
Experiments which the Station has conducted show that the gum-yielding capacity
of a turpentine tree declines very rapidly following crown defoliation and recovers
only gradually as new leaves develop. When part of the crown is killed the former
yielding capacity recovers in proportion to the rebuilding of the former crown
surface.
When fires cause defoliation of at least two-thirds of the crown, it is good practice
to discontinue turpentining for a season, not only to avoid the low yields during
that season, but also to permit the tree to recover its vitality.
