Fire and grazing to improve wildlife habitat on introduced grass monocultures in Texas

摘要：

Introduction Guineagrass (Urochloa maxima) and bermudagrass ( Cynodon dacty lon) were introduced into the USA with the objective of improving forage production for cattle.However,these grasses became invasive and replaced native plant communities valuable for wildlife.Invasive plant species are considered the second most important threat to conservation of biodiversity (Zalba et al.2000).Prescribed fire can be used to stimulate regrowth,and improve quality and preference by grazing animals as well as to increase insect abundance,wildlife and cattle usually concentrate on burned areas due to these factors.This phenomena provides an opportunity to use prescribed fire,followed by grazing,to reduce stands of invasive exotic grasses and allow native plants an opportunity to recolonize these areas.
