First reported from the wild in Britain in 1945, the Chinese water deer
is one of those introduced species that has stayed below the radar of those
calling for the control and removal of such exotic imports. The reason for this
is that we have not yet seen the development of any conservation problems
associated with the species. Chinese water deer to not occur at the high
densities that the introduced muntjac populations sometimes reach and there has
only been occasional damage to agriculture, and none to forestry. Most of the
established populations are still centred on the areas into which they
initially escaped from captive collections and there has been only a very
modest amount of expansion into new sites.
In Norfolk this small deer is most commonly encountered in the Broads,
favouring reedbeds and the surrounding grazing marshes and farmland that
provide feeding opportunities. Woodland habitats are also used and there is a
preference for denser vegetation, which provides cover. Over recent years we
have seen a gradual extension to the Chinese water deer’s range, with
increasing numbers of records coming from the grazing marshes of the North
Norfolk coast. Records from Titchwell and Sculthorpe Moor in the west of the
county underline the distance travelled. There are very occasional inland
records from the Brecks, perhaps the result of individuals escaping from a
former wildlife collection.
At this time of the year, these small deer are readily seen around the
Broads and south into the river marshes of the Yare Valley. In their thick
winter coats they appear stocky but at other times of the year I think they
seem rather scrawny and very different from the solid muntjac that are more
commonly encountered. The adult males have a long and curving upper canine that
protrudes as a ‘tusk’. Readily visible in the field it proves a useful feature
for identification. These teeth are smaller in the females and do not protrude.
There are probably fewer than 5,000 of these Asian deer in England but
it has been a while since the last attempt to survey their numbers. Indications
of their presence mostly come from birdwatchers and from those individuals
reported dead on the county’s roads, following collision with traffic.
