Description
Summary:Effects of harrowing and fertilisation treatment techniques on the abundance and specific diversity of understory vegetation and stand stem volume increment, were evaluated. Using the quadrat method, floristic surveys were performed every spring in the 3 years following the application of treatments. During the experimental period the mean total number of species per treatment plot was greatest in C and least in treatment harrowing and fertilisation (HF). Statistically significant differences between treatments occurred only 1 and 8 years after treatment application. A general decrease of species richness over time was observed in all treatments and may be related to competition for light, water, and nutrients with the eucalyptus trees.
