Cover estimates from point intercept and digital photography method with varying intensity (SP25, SP49, and -based methods, and d–e PV, NPV, and bare soil cover estimates of all Table 2 Summary statistics of PV, NPV, and BS cover estimates of steppe types and field-based methods	./cache/work_tkf3lpfl2bfjhjroxbrc4xisey.pdf	./txt/work_tkf3lpfl2bfjhjroxbrc4xisey.txt
