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
