Origin and Distribution:
  • Originally from china, the muntjac deer was deliberately introduced to England in the early 20th Century.
  • It is now widespread in England and Wales.

  • Muntjac deer destroy the understory of forests by overgrazing; act as a reservoir for diseases (bovine TB) and parasites for domestic livestock; strip bark from trees and trampling of vegetation which in turn may lead to increased soil erosion.

Is it found in Northern Ireland?
  • It is found in Northern Ireland.
  • More distribution information can be found at NBN Atlas NI.

You can help by reporting any sightings: @ the Centre for Environmental Data & Recording (CEDaR) - Or via the iRecord App.
How did it get Here?
  • Importing these species is the only viable pathway of introduction. Therefore, the main pathways into Ireland will be through the main ports of entry (by sea or by air). Importation of this species maybe allowed under licence but illegal smuggling is also a very real possibility.

Prevent Spread
  • These animals tend to be very mobile so are capable of moving freely throughout the country side. However, long distance movement by individuals remains a possibility. This activity is currently prohibited in both jurisdictions and therefore an individual undertaking movement of deer species is committing an offence.
  • Do not introduce muntjac.
  • Report all sightings.

Current Legislative Position (Listed on 03 August 2016)
  • This species must not intentionally be brought into the Union; kept; bred; transported to, from or within the United Kingdom, unless for the transportation to facilities in the context of eradication; placed on the market; used or exchanged; permitted to reproduce, grown or cultivated; or released into the environment.
