| Abstract: | The effect of human disturbance on mangrove forest may be substantially different from the effects of natural disturbances.
This paper describes differences in vegetation composition and structure of five vegetation types in two mangrove areas near
Darwin, Australia, 25 years after disturbance. The vegetation in clear-felled forest showed more adult Avicennia marina than in the hurricane-affected forest, and a virtual absence of A. marina juveniles and saplings. This indicates that A. marina will be replaced by other species in the canopy, showing a multi-phase vegetation development in mangrove forest after human
disturbance. The mechanism of disturbance and the conditions after clearing therefore affects the vegetation composition for
at least 25 years after this disturbance took place. |
