The frequency and extent of uncontrolled grass fires in the Rwenzori National Park, Uganda
Authors:S K ELTRINGHAM
Institution:Uganda Institute of Ecology
Abstract:The area of grassland affected by uncontrolled fires was recorded in the Rwenzori National Park for each dry season between July 1970 and July 1973 with the exception of the January 1973 season. The seasonal total of burnt grassland rose to a peak of 32 7% in January 1971 but there was then a marked decline to a negligible level in July 1971. This was followed by a further steady rise which by July 1973 had reached to within 3% of the previous peak. 13 4% of the park was burnt at least once a year on average, and 55 3% was burnt at some time or other during the 3 years. Burning was not uniformly distributed throughout the park and four regions at high risk from fire are identified for particular attention should a fire control policy be introduced. The need for a controlled burning policy is emphasized particularly in view of the destruction of trees which is taking place through the agency of elephants.
