Revegetation of marginalised rangelands using pastoral halophytes is considered an appropriate scientific and environmental approach to rehabilitation. Atriplex halimus L. (Amaranthaceae), A. mollis Desf. (Amaranthaceae), Cenchrus ciliaris L. (Poaceae) and Lotus creticus L. (Fabaceae) are promising species for arid rangeland rehabilitation, because of their adaptation and palatability. Dry biomass, in vitro digestibility, ash, nitrogen, neutral detergent fibre, acid detergent fibre and lignin of 50% aboveground biomass (upper half of tufts assumed to be the firstly consumed parts by livestock) of these species were evaluated in the Sidi Makhlouf region of southern Tunisia, during December 2015, June 2016 and December 2016. Digestibility increased with nitrogen content and both of these variables are decreasing when the dry matter and fibre contents increased. Four groups of species were obtained, based on digestibility and nitrogen and lignin contents. A. halimus and L. creticus harvested in the winter of 2015 have superior forage quality. A. mollis was better able to regenerate after winter harvest. Forage quality of C. ciliaris and L. creticus decreased with seasonal variation. The rehabilitation of marginal saline dryland remains possible with local pastoral halophytes that produce good forage quality and may provide many economic and environmental benefits for local users.

使用牧草盐生植物对边缘化牧场进行植被恢复被认为是适当的科学和环境修复方法。滨藜（A菜科），A.mollis Desf。（A菜科），Cenchrus ciliaris L.（禾本科）和Lotus creticus L.（Fabaceae）由于它们的适应性和适口性，是干旱草原恢复的有前途的物种。体外干生物质在突尼斯南部的Sidi Makhlouf地区，评估了这些物种的消化率，灰分，氮，中性清洁剂纤维，酸性清洁剂纤维和木质素（地上生物量的50％被认为是牲畜首先消耗的部分）的木质部， 2015年12月，2016年6月和2016年12月。消化率随氮含量增加而增加，干物质和纤维含量增加时，这两个变量均降低。根据消化率以及氮和木质素含量，获得了四类物种。2015年冬季收获的哈利木。和etic草具有出色的饲草质量。冬季收获后，molis A. mollis能够更好地再生。的牧草质量C.纤毛和creticus随季节变化而减少。边缘牧草盐生植物仍然有可能恢复边缘盐碱旱地，生产出优质的草料，并可能为当地使用者提供许多经济和环境效益。
