Woody plant encroachment and wildfire may both have major effects on species richness and composition, yet studies that assess these two factors in combination are rare. We asked the following specific questions: (1) how did juniper cover change over a decade in the study area; what are the effects of juniper encroachment and subsequent wildfire on(2) plant species richness; and (3) vegetation composition?

木本植物的侵占和野火对植物物种丰富度和组成的影响：森林-草原马赛克中的时间变化

木本植物的侵占和野火都可能对物种的丰富度和组成产生重大影响，但是很少有评估将这两个因素结合在一起的研究。我们提出了以下具体问题：（1）十年来，杜松在研究区域的覆盖率如何变化；杜松和随后的野火对（2）植物物种丰富度有何影响; （3）植被组成？
