Answer
Yes.
Work Step by Step
Recall that for the percentage of total plant cover at the five Dry Steppe sites only, all three central tendency measures (the mean, median and the mode) were about $40$ percent.
For the Gobi Desert sites all three were much lower, in the interval $26$ to $30$ percent.
So, yes, the center of the distribution for total plant cover percentage appears to be different at the two regions.
