AbstractWoody plant encroachment threatens ecosystem services and functioning, thereby reducing herbaceous population persistence community stability. We assessed the impact of woody removal intensity (WRI) on grass ground cover, composition, diversity richness, rangeland condition in a South African savanna over period four growing seasons (2018–2022). Selective tree was applied to reduce density (4 065 ± 109 plants ha−1) control (0% WRI) 10, 20, 50, 75 100% WRIs, with replicates per WRI....
The removal of trees in rangelands can create gaps and lead to increased grass production that could suppress subsequent tree seedling establishment growth. However, also enhance the growth remaining trees. We conducted a field experiment at two savanna sites with different soil texture woody species. used 24 plots each site determine effect tree-removal intensities (0%, 10%, 20%, 50%, 75% 100%) on production, tree-seedling growth, large Site 1 was previously cultivated severely-eroded...
Mechanical and chemical methods are widely used to control woody plant encroachment in many African countries. However, very little is known about the effectiveness of these among species different ages. We conducted a field experiment determine effects tree removal treatments (10%, 20%, 50%, 75% 100%) herbicide application (Picloram; 6 mL L-1) on resprouting ability vigour 12 species. examined 20 plots (30 m × 30 m) that were each subjected removal, followed by half stems for plot. All this...
Along with the woody plant expansion that is predicted to continue at expense of grassy layer increasing societal demand for animal protein and livestock products. Unless concerted efforts by land users, ecologists, scientists are made increase utilization trees shrubs as forage, it will be impossible meet future meat We conducted two short-term pen experiments determine effects (1) supplementation polyethylene glycol (PEG-a polymer purported bind neutralize negative tannins), a high-protein...
