2. SLM技术的说明
2.1 技术简介
技术定义:
Firebreaks are stripes cleared of vegetation that divide a continuous forest in smaller patches to reduce spreading of wildfires and allow intervention.
2.2 技术的详细说明
说明:
The technology consists of creating gaps of vegetation of about 5 to 7 meters, every 50 to 75 meters distance contourline large forested areas. These clear strips are connected to main roads having varying length in relation to the size of the area.
Purpose of the Technology: Fire breaks act as a barrier to stop or slow the progress of fires and allow firefighters to better position themselves to operate.
Establishment / maintenance activities and inputs: Clearing activities which must be carried out annually by specialized workers using minor devices (hand and hedge cutter).
Natural / human environment: This technology is applied mostly in publicly owned woods (or very large private woods). The network of these fire strips is rather dense as the number of flammable species increases. So it creates patches of 2500 to 5000 meters according to the type of species. The context of production is characterised by a medium level of mechanisation (only the most demanding operations are carried out using mechanical means), the production system is essentially mixed, a small part is destined for personal consumption whilst the bulk of production is destined for local markets. The property is predominantly privately owned but also includes some public land, especially in the case of pasture land. Most farms in the area are livestock farms whilst the agricultural component is destined exclusively for private consumption.

注释:
Major land use problems (compiler’s opinion): In some wooded areas, especially nearest the roads, there is an excessive amount of undergrowth (with some shrubs reaching a height in excess of two metres) which leaves the area vulnerable to the start and spread of forest fires.
Major land use problems (land users’ perception): The increase in shrubs has increased fire risk.
