Abstract: An outline is provided of stand development and mortality in Pinus radiata at Rotohu forest. Factors possibly conducive to this heavy mortality are discussed. It is indicated that there is no simple primary cause, but that an interrelationship of natural competitive effects with a superimposed and dependent population of Sirex noctilio forms the underlying mechanism. A hypothetical pattern for this mechanism is given, together with likely measures for controlling it.
