metaMDS and envfit: Help reading output

>Fish.fit
The output of Fish.fit was as follows (table truncated):
Dim1 Dim2 r2 Pr(>r)
DrainArea -0.5923233 -0.8057004 0.7674 0.000999 ***
Flow -0.5283236 -0.8490431 0.7847 0.000999 ***
StrmWidth -0.6993457 -0.7147836 0.6759 0.000999 ***
Gradient 0.4541225 0.8909392 0.2085 0.010989 *
I'd like to better understand how to read this table. I understand that Dim1 and Dim2 refer to the dimensions of the vectors produced by envfit, and r2 is the r-squared...
