Thankyou for the info Rob.
I believe there are Muntjac present in the county. They have certainly been recorded in the Quantocks, albeit in low numbers. They may seem cute and cuddly but they are considered to be an invasive species and can do a lot of damage to plants, trees and crops!
Driving to work south of Sherbone there was a dead Muntjac deer that had been hit on the road,not sure how many of these are in the area but this was my first sighting of this species for Dorset.Do we have them in Somerset?.
