摘要: Abstract This study examined the response of summer and winter annuals perennials in a shrub-invaded arid plant community to combinations fire grazing by cattle determine their effects on individual abundances, species richness diversity. Thirteen differed significantly abundance across burn treatment while nine treatment. Summer annual plants were more abundant, diversity higher plots. Most affected either burning or indicating that these disturbances affect this relatively independently.
