Well, I looked in the help page to manova and it transferred me to a 
summary.manova help page with example which seems to organize multiple 
respodse to a matrix. So I presume

Y<- cbind(isol,hcom,habarea,inclin,windprot,shrubcov,herbh,baregr,flowcov)

and

manova(Y~pcor, data=pcor.df)

should work as expected, hopefully.
