Mesquite savanna development using low-intensity fires and Reclaim herbicide
Introduction Mesquite in dense thickets reduce grass production and make livestock management more difficult. To compound the problem, treatments which top-kill mesquite, such as chaining, shredding, high-intensity fires, or herbicides such as 2,4,5T or triclopyr (Remedy), stimulate regrowth from stem bases and increase stem number per plant and per land area (Fisher et al. 1959). An alternativ...
متن کاملContrasting effects of cattle and wildlife on the vegetation development of a savanna landscape mosaic
1. Through their effects on plant communities, herbivores can exert strong direct and indirect effects on savanna ecosystems and have the potential to create andmaintain savanna landscape heterogeneity. Throughout much of sub-Saharan Africa, periodic creation and abandonment of livestock corrals leads to landscape mosaics of long-term ecosystem hotspots that attract both cattle and large ungula...

متن کاملEffects of repeated burning on woody vegetation structure and composition in a semi-arid southern African savanna
The objective of this study was to investigate the effects of repeated dry season annual hot fires on woody plants in a semi-arid southern African savanna in Zimbabwe. Parts of the National University of Science and Technology (NUST) research fields in Bulawayo, Zimbabwe have been burnt annually in the dry season between 1994 and 2003 in order to control bush encroachment. The present study was...
متن کاملMultiple Scales of Control on the Structure and Spatial Distribution of Woody Vegetation in African Savanna Watersheds
Factors controlling savanna woody vegetation structure vary at multiple spatial and temporal scales, and as a consequence, unraveling their combined effects has proven to be a classic challenge in savanna ecology. We used airborne LiDAR (light detection and ranging) to map three-dimensional woody vegetation structure throughout four savanna watersheds, each contrasting in geologic substrate and...
