Abstract Growth and survival of kohekohe (Dysoxylum
spectabile) seedlings planted in forest gaps and in non-gap micro-environments
were monitored in Kauaeranga valley, near Thames, New Zealand. Seedlings
in gaps and on gap edges grew faster than seedlings in darker forest environments.
Seedlings protected from vertebrate browsing (mostly possum) grew faster
and survived better than unprotected seedlings. Although browse appeared
to be the primary cause of mortality, disease and damage from falling debris
were also significant.
Keywords Dysoxylum spectabile; seedlings; browsers;
