This Concept Map, created with IHMC CmapTools, has information related to: Threats09, Weed invasion (exotic & native) this decreases Grassland Indicators - hetergeneous structure (spatial & temporal mosaic) - low weed abundance - high native species diversity - high area of native grass - soil structure with low compaction, high infiltrat. - system self-sustaining, Grassland Indicators - hetergeneous structure (spatial & temporal mosaic) - low weed abundance - high native species diversity - high area of native grass - soil structure with low compaction, high infiltrat. - system self-sustaining Changes in state of indicators impacts on Grassland invertebrates, Urban development reduced habitat Grassland birds, Grassland Indicators - hetergeneous structure (spatial & temporal mosaic) - low weed abundance - high native species diversity - high area of native grass - soil structure with low compaction, high infiltrat. - system self-sustaining Changes in state of indicators impacts on Threatened species and communities, Nutrient and fertilizer inputs more suitable for Weed invasion (exotic & native), Trampling and soil compaction causes Damage to soil crust, Change in species composition decreases Grassland Indicators - hetergeneous structure (spatial & temporal mosaic) - low weed abundance - high native species diversity - high area of native grass - soil structure with low compaction, high infiltrat. - system self-sustaining, Grassland Indicators - hetergeneous structure (spatial & temporal mosaic) - low weed abundance - high native species diversity - high area of native grass - soil structure with low compaction, high infiltrat. - system self-sustaining Changes in state of indicators impacts on Grassland birds, Illegal collection (e.g. orchids) reduce abundance Threatened species and communities, Removal of rocks and other shelter reduce habitat Grassland invertebrates, Lack of awarenss (incomplete ecological knowledge?) can cause Inappropriate disturbance regime, Illegal shooting reduce abundance Grassland birds, Dominant grass species become over-abundant reduces florisitc diversity this decreases Grassland Indicators - hetergeneous structure (spatial & temporal mosaic) - low weed abundance - high native species diversity - high area of native grass - soil structure with low compaction, high infiltrat. - system self-sustaining, Introduced herbivores (e.g.rabbits) gaps seeds Weed invasion (exotic & native), Urban development increases Fragmentation, Urban development reduced habitat Grassland reptiles, Fragmentation increases Edge effects, Trampling and soil compaction has Hydrological impacts, Introduced predators reduce abundance Grassland reptiles, Grassland invertebrates monitored Level of Biomass
