N2  - The grasslands of northern Thailand are a consequence of shifting cultivation practices of local opium-growing farmers and they are maintained by annual fires. Their productivity is low and they are a fire hazard in the dry season. In swiddening systems, a grassland fallow appears inferior to forest as a means of restoring soil fertility after a cropping phase. Imperata cylindrica cannot be classed as a serious weed in this area; the grass provides some foragefor village cattle, is seldom a problem in cultivated fields, and tends to decline or disappear if continually grazed by cattle.
