Neutral Grassland

Effects and implications

• Increases in proportion of productive grasses at expense of fine leaved grasses.
• Reduces species richness, especially among forbs
• Possible reductions in productivity
• Changes in species composition
• Loss of rare or endangered species.
• Loss of annuals and forbs will have implications for sustainability, due to the short lived nature of the seed bank (Bossuyt et al 2005) and the isolation of many of these small areas of grassland.
