Resumen:
The Mimosa is a leguminous tree replacement, pioneer in the semiarid environment. It is a native forage for ruminants that consume its leaves, fruits and branches. Fito population in the Caatinga semiarid, Mimosa acquires importance because of their frequency and abundance. To enable a better use of this plant species as fodder, the technique of relegation is being used, which aims to reduce the height of woody species, stimulate regrowth. This study aimed to evaluate the effects of different cutting heights on regrowth and survival of Mimosa, seeking ways to establish rational management of the Caatinga. This research revealed that the Mimosa can be controlled through cutting practices already in use in the northeastern Caatinga. And that to achieve effectiveness in these actions it is recommended that the cut be held in September and the cutting height from 75 to 100 cm above the ground, with sprouts and cut their stems when they reach a diameter of 7 mm. The data collected showed that the uniformity cut in December is of little efficacy, regardless of the height of the cut.
