threats to grasslands
Heavy grazing can remove some species, compact the soil, and increase weed invasion. This has resulted in a widespread loss of wildlife habitat.Grassland soil is rich, and almost anything can be grown there. The region where the terai grasslands are found is becoming increasingly populated and the pressures associated with human encroachment are having an increasing impact on the range and quality of grassland habitats. Threat/Issue Gr1 Cropping, development, and transportation projects can result in outright destruction of native grasslands. of Assam and the Ministry of Environment & Forest, Govt. Agricultural crops, such as corn, wheat, and other grains grow well in grassland soils and climate. Threats to our native temperate grasslands include clearing, nutrient enrichment, inappropriate grazing, altered burning practices, neglect, fragmentation, tree planting and the invasion of exotic weed species like Serrated Tussock, African Lovegrass, St John's Wort and Phalaris. The primary threat faces by grassland ecosystems is the destruction of their habitat for agricultural use.
Therefore any change to grassland growth patterns could have a significant impact on earth system processes.This investigation was part of the global research co-operative Dr Carly Stevens said: “Atmospheric nitrogen, a pollutant which most people have probably never heard of, is actually having a great impact on our environment globally.“Grassland habitats are important for conservation, atmospheric nitrogen is increasing productivity meaning that the habitat is being changed. The main threats to conserving Victoria's remaining native grasslands include; clearing of native grassland for urban expansion (buildings, roads, infrastructure) conversion of native grassland area to crops and introduced pasture invasion by exotic plants Every year intensive burning is destroying vast areas of suitable habitat for the pygmy hogs keeping the species at very low levels and limiting their recovery.Pygmy Hog Conservation Programme is a collaborative project of Durrell Wildlife Conservation Trust, IUCN/SSC Wild Pig Specialist Group,Forest Department, Govt.
