how to show a plot without overlaying the text on top of the another text?

Hi R user,
I have created using metaNMDS (Nonmetirc Multidimensional Scaling, MDS) to
show species composition but some of the species are concentrated at some
of the sites so that the name of the species are overlaid and it was
almost impossible to read the species name in the figure. I was wondering
how
we can show the plot without overlaying the text on top of another.
I used the following to create the plot. would you mind to suggest me?

comm.bc.mds <- metaMDS(dat, dist = "bray")
ordiplot(comm.bc.mds, display = "sites", type = "text")
ordipointlabel(comm.bc.mds,font = c(1, 1), cex = c(0.5, 0.3))

Thanks

MW
