RESOLVED: (Thanks Miner!) Best test? Before and After Cattle Trial

It looks so different! Part of the problem is the cows totally trashed this species. I want to keep the 0 values as they are legitimate (there was a tree, but it has been destroyed by cattle, but the significance of this result is not coming across in the Mood's test, (could this be the 0's?). Therefore, should I attempt some transformations, I am researching what is best to deal with 0's, perhaps I could square root the data?
I totally agree about reducing the chances of errors, I'll look into it there's a chance I have an institutional subscription... Hopefully the institution can come in handy for something
