Fire management units as strategy of prevention, control and restoration in forest fires
Fire management involves the implementation of a series of strategies and activities within the area of interest. Where should be located and size the place where specific activities must be carried out, referring mainly to the prevention and combating of forest fires. Finally, conditions must be located to define the restoration activities most suited to the place of interest. This can be based on the knowledge of the area and the evaluation criteria (ecological, cultural, social and economic) of natural resources. In addition, areas should be zoned according to their risk levels or danger of forest fires. Based on this, a series of working polygons can be defined, within the area of interest, which are called fire management units (FMU). However, to define them, the following must be identified: a) the relationship with the zoning of the conservation and management program; b) zones of exclusion and prohibition of fire (sensitive or influenced ecosystems), fire management (adapted ecosystems) subject to exploitation, conservation, and restoration, as well as agricultural areas; c) establish a sub-zoning for the use of fire as areas of controlled use, zones of use for periods of time, among others; d) differentiation of fire protection zones, according to: risk of forest fires (derived from high human activity or natural causes); dangerousness (by fuel types, topography, climatic conditions, among others), as well as fire regimes (occurrence or historical record of fires and the response of vegetation to fire) and by the high economic, social and ecological value, whose combination It will generate the priority areas of attention, in accordance with the management objectives. According to the above, a semblance of the concept and use of FMUs is presented.
