Matrix of environmental risks in semi-arid ranching sub-system - LGS3

Resource base | Risks and opportunities | Underlying factors
Biodiversity Vegetation structure | (+) Improvement of ground cover | Pasture use and maintenance : introduction of useful plants
(+) Maintenance of ground cover | Pasture use and maintenance : rotational grazing
(-) Degradation of ground cover | Excessive grazing and browsing
(-) Excessive increase of tree and shrub density | Good grazing management
(+) Reduction of fire hazard | Reduction of combustible material by grazing and browsing
Biodiversity Plant species | (+) Improvement of botanical diversity | Good grazing management
(-) Weed invasion | Invasive weed as a result of poor grazing management : Seed dissemination by animals (and humans)
(-) Weed invasion | Seed dispersion by animals
Biodiversity Animal species | (+) Protection of wildlife and habitats | Mixed ranching game/cattle
