Control of Mission Grass by Using Native Trees At Different Densities At Disturbed Site.

Savannahs function is maintained with native grasses, but the introduction of the alien grasses or plants effects the normal working of the savannah or woodland. These invasive grasses have the power to change or alter the functions of the ecosystem through change in the composition of other species.

This experiment investigated the effect of shade on of mission grass (Annual Pennisetum pedicellatum and perennial Pennisetum polystachion) on disturbed site. Their vegetative and reproductive stages were documented under different densities of native trees. Data were collected at different stages throughout the growing season in order to track impact different densities of native trees toward the control of mission grass.

 

The data were collected from every plot. For data collection up to three clumps were selected from each plot and marked with marking tape randomly so that every time data was collected from the same clumps.

The results reveal that under different tree density mission grass behave differently under different canopy covers or shade levels.
