Impact of rest duration and land tenure on biomass (productivity) of degraded rangelands in Tunisia
To investigated changes in the spatial and temporal patterns of community structure and rangeland function in response to the period of rest. A total of 20 sites in southern Tunisia (Tataouine) covering more than 15000 ha including 12 private rangelands and 4 communal subjected to grazing management, in addition to 4 freely grazed site which considered as control were retained for detailed monitoring-assessment study. This data could be one of the tools to examine the impact and potential of traditional best practices for rangeland restoration on regeneration and the persistence of plant species by monitoring the evolution of specific characters (global plant cover, specific frequencies, flora richness and the plant density, biomass, rangeland production and carrying capacity). The state of the soil surface (wind veil, crust, stones, litter) is also studied to monitor and assess changes of soil structure. Range biomass production were estimated by clipping the vegetation inside 5 quadrats of 1m2 each for annual species and by clipping the half of the potentially grazeable biomass (according to the rule take the half and leave the half) of 10 tufts of each species for perennial vegetation. The total biomass of perennial species was estimated by multiplying the mean available biomass per individual by the density of the species.
