The Chinese Water Deer is the least common of our wild deer population and it is often said we know little about it. This is invariably a reflection of its limited geographic distribution. Having been in this country longer than the Muntjac deer and having the potential of a high fecundity rate, raises the question of their very limited expansion within England. Whatever the reasons for this, the Chinese Water Deer is a biologically significant deer and a charming addition to our wild deer population. It deserves to be cherished, not least because in their native land they are 'red listed' as an endangered species.
