The report and field study were done as part of the Bush Encroachment Research, Monitoring and Management Project in Namibia. Nearly 2000 test plots located throughout north central Namibia were included in the field study. For each test plot, the number of bushes per hectare for various heights and species of bush were recorded. Results of the field tests were then compared to a number of environmental factors, such as soil type, rainfall, and agro-ecological zone. The results of the field counts for each plot were recorded on Excel spreadsheets. CSA obtained these spreadsheets, and they can be provided to VTT researchers (upon request) should they be needed.
