Modelling trade offs between ecological and economic performances in grazed grasslands:importance of temporal stocking density

摘要：

Introduction Recent changes in grassland management have led to increasing threats on farmland birds populations ( Newton,2004).Through its impact on sward structure,grazing can promote suitable habitats for ground nesting birds ( Tichit,Renault and Potter,2005).However it can also have negative side effects on birds dynamics through nest trampling.We developed a cost effectiveness approach to asses the effect of nest trampling by cattle on the economic and ecological performances of grazed grasslands.
