Observational analysis reveals improved growth in pruned white pine trees, indicating effective reclamation strategies.
A method of reclaiming severely weeriled white pine plantations was developed in 1930. Observations carried on for a four-year period show that the pruned trees are improving. Most of the girdled trees have died, and the stand has been opened gradually. The method has worked out satisfactorily according to the expectations of the authors.
