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 ...
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), ...
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 ...
Revival of traditional best practices for rangeland restoration under climate change in the dry areas: A case study from Southern Tunisia
The purpose of this paper is to illustrate the benefits of reintroducing traditional grazing systems practices for improving arid rangelands. Grazing is the most extensive land use in southern Tunisia, but the rangelands ...
Enhancing sustainability and fodder production of lowland pastures through fencing and conservation agriculture in arid agro-pastoral ecosystems
The short-term fencing effects on vegetation in dryland landscape depressions are analyzed and the economic performance of grazing-only and integrated grazing with cropping in regard to land capital are compared. The goal ...
Impact of Grazing Regimes, Landscape Aspect, and Elevation on Plant Life Form Types in Managed Arid Montane Rangelands
Arid steppes, with scattered vegetation, are commonly qualified as degraded ecosystems. Their natural vegetation cover is affected by both abiotic stresses and human activities and, therefore, suitable managements are ...
Community diversity, functional traits and adaptation of Stipa tenacissima L. under different grazing regimes in a North African arid montane rangeland
The mountain rangeland chain of Matmata (southern Tunisia) is characterised by an arid Mediterranean climate with severe droughts and high temperatures, combined with substantial human disturbance. In order to withstand ...
Rangeland Biodiversity and Climate Variability: Supporting the Need for Flexible Grazing Management
Resting or grazing exclusion is an effective practice widely adopted to restore degraded, arid rangelands. To understand its effect on plant diversity, we studied Hill’s diversity indices during two growing seasons ...
