Is long-term protection useful for the regeneration of disturbed plant communities in dry areas?
In dry areas, natural plant communities are mainly affected by climatic stress and human disturbances – overgrazing, ploughing and biomass harvesting – that accelerate their degradation. Management techniques, including ...
Measurement of the aboveground biomass of some rangeland species using a digital nondestructive technique
Plant biomass is usually assumed to be positively correlated with canopy cover. Measurements of
canopy cover can now be easily and precisely made through image processing of high-resolution
digital photography. This study ...
Effect of protection on plant community dynamics in the Mediterranean arid zone of southern Tunisia: a case study from Bou Hedma national park
Ecosystems protected from heavy grazing impacts, such as national parks and refuges, are generally considered to sustain higher plant species diversity and better ecosystem composition and structure compared to heavily ...
Managing agrosilvopastoral systems: promoting halothytic drought tolerant shrub species; Atriplex mollis Desf.: mitigating highly saline soils
Factsheet about Atriplex mollis description, environmental benefits, distribution, effective management and feeding value.
Managing rangelands: promoting highly palatable species with good nutritive Value Lotus creticus L.: high forage quality and greatly salinity tolerance
Fact sheet about Lotus creticus as a high forage quality, it is among recommended species on restoration of marginal and degraded lands in arid areas. It is used in sand dune stabilization thanks to its creeping canopy and ...
Revegetation of marginal saline rangelands of southern Tunisia using pastoral halophytes
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), ...
The Relevance of Rest Periods in Rangeland Management for Plant Cover and Species Composition in Tataouine, Tunisia, Spring
In southern Tunisia, rangelands are overexploited because the animal needs highly exceed plant production. For most of the skeletal desert soil, the overall vegetation covering oscillates between 1 and 10%; the perennial ...
The Relevance of Rest Periods in Rangeland Management for Biomass Rehabilitation in Tataouine, Tunisia, Spring 2017
Field visits were carried out during March 2017 and allowed to identify and classify the sites subjected to rest according to the land tenure system and age of the implementation of the technique. During these visits, the ...
A participatory sustainable rangeland management toolkit with a holistic and multidisciplinary approach
Panorama solutions on Sustainable Rangeland Management (SRM) toolkit which is tested in North Africa and West Asia (NAWA region), with a specific focus on Tunisia, Jordan and Uzbekistan, and offers a package of holistic ...
Diversity of desert rangelands of Tunisia
Plants are important components of any rangeland. However, the importance of desert rangeland plant diversity has often been underestimated. It has been argued that desert rangelands of Tunisia in good ecological condition ...
