Deer numbers in the Cotswolds have increased over the years and continue to increase. Too many deer can lead to habitat damage, especially in woodlands, crop damage, increased collisions with road traffic and disease. Deer have been managed in the Cotswolds for many years. This leaflet explains why deer need to be managed and how a properly managed population of deer is in balance with its environment, is healthy and can be a source of local income through stalking and sales of venison. Deer species and numbers There are currently four species of wild deer in the Cotswolds: fallow, muntjac, roe and sika. Only roe deer are native to the UK. However fallow deer have been present in the region for many centuries and are seen as a traditional part of the Cotswold landscape. Fallow are already present in high densities throughout the AONB, muntjac and roe are present at low to medium densities in many parts of the AONB but are increasing in numbers and expanding their ranges, whilst sika are present only in small numbers in a restricted area around Wychwood. The extension in geographic range of deer and the increase in deer densities have been encouraged by changes in land use, particularly the move to year-round crops, set-aside, expansion of forestry and increased natural/semi-natural habitat connectivity. These changes have increased the amount of suitable habitat for both deer foraging and shelter. In addition, warmer winters mean that there is a more plentiful supply of food all year round, with fewer and shorter periods of harsh conditions, resulting in higher rates of breeding success and survival. There are no natural predators of deer in the UK. Fallow deer There is currently no reason why the trend in increasing deer numbers and range expansion will not continue. A sustainable population of wild deer A sustainable population of wild deer is one which is in balance with the environment and with minimal negative effects on the economic or social needs of those who live, work in or visit the countryside. ■ Densities of fallow deer are already too high in parts of the Cotswolds and are having a negative impact on habitats. These populations must be reduced if a sustainable balance is to be achieved. ■ Muntjac deer are also causing negative impacts and should be managed to minimize further escalation of the numbers and spread of this non-native invasive species. ■ Roe deer, whilst currently not causing unacceptable damage, will need to be monitored and more intensively managed if negative impacts increase.

SIKA deer 3 4 4 Managing deer in the Cotswolds Issues and impacts Habitats and land use Many Cotswolds woodlands (a significant number of which are small ancient woodlands particularly vulnerable to damage from deer) are suffering from the adverse impacts caused by high densities of deer. These impacts include bark stripping, browsing and fraying. This reduces the natural regeneration of trees and shrubs, reduces the survival of coppice stools, and may prevent other plants from flowering and seeding so reducing the floristic diversity of woodlands. There is also evidence of impacts on populations of butterflies and birds. In addition, damage affects the quality and value of timber and coppice growth. 8 Deer can impact on agricultural and horticultural crops, especially when adjacent to woodland, through browsing and trampling. They may also visit and damage gardens in villages and even in more urban areas. Deer vehicle collisions Rising numbers of deer, combined with the growth in road traffic volume and speed, means that there are an increasing number of road traffic accidents involving deer. It is estimated that there may be as many as 74,000 deerrelated road traffic accidents each year across Great Britain. Benefits from deer management The prime purpose of managing deer is to maintain a healthy population of deer in balance with their environment. But there are wider benefits relating to the rural economy and tourism and these have potential for development in the Cotswolds: ■ A viable local venison industry. Currently, the majority of deer carcasses resulting from deer culling in the Cotswolds are sold direct to game processors outside the AONB. Prices received fluctuate depending upon regional and national demands. Recent changes to Meat Hygiene Regulations have relaxed some of the constraints on producing small amounts of wild game meat, including venison, for local sale direct to the final consumer and this could open up a number of opportunities for establishing local venison production, possibly exploiting the Cotswolds brand. ■ Increasing the opportunities for tourism. The public love to see deer and this could be exploited in the Cotswolds, as elsewhere, through the provision of opportunities to watch deer, for example on guided walks. Sources of advice and support for deer management Advice on deer management, including to local Deer Management Groups, is provided through the Deer Initiative (DI). The DI is a broad partnership of statutory, voluntary and private organisations dedicated to “the achievement and maintenance of a sustainable and healthy population of wild deer in England and Wales”. The partners abide by the principles of The Deer Accord and encourage others to share 9 High deer numbers are known to attract poachers who often use inhumane methods to kill deer. Deer management 9 Animal health When deer numbers exceed the ability of the habitat to supply adequate food their body condition declines leading to increased risk of disease. Active management of deer helps maintain a healthy deer population by keeping numbers in balance with their food supply. Deer related diseases Deer suffer from or may be implicated in zoonoses such as Lyme disease and animal diseases such as Bovine Tuberculosis (bTB), Foot and Mouth, and Bluetongue. In the Cotswolds bTB is of particular concern. A recently completed project to identify the level of bTB in deer populations in the South West indicates that high densities of deer can be associated with higher levels of bTB in deer, although the risk of spread to domestic livestock is low. Two such populations are known to be within the central Cotswolds. 7 6 properly and hygienically. Persons selling direct to the public must be registered with the local authority and Approved Game Handlers (who can also export venison) must have their carcasses inspected by Veterinary Inspectors. Poaching For the deer, in addition to those killed at the time, at least 10% of deer hit by vehicles are likely to die some time later of their injuries away from the collision site. Mapping of deervehicle collisions shows a number of ‘hotspots’ within the Cotswolds AONB. The management of deer is the responsibility of the landowner. It should be a continuous, long term process and not done only in response to a particular problem. It is much more effective when landowners work together as part of a Deer Management Group. There are two established Deer Management Groups in the Cotswolds, one based around Wychwood and another in the central part of the AONB which is one of the most active in the country. However, these groups do not provide deer management cover across the whole AONB area and there is a need for other groups to be established. Alongside other measures deer management involves population control through culling. Deer culling should only be undertaken by stalkers (preferably experienced and qualified) who are working to clear objectives and Best Practice Guidelines. Deer density is estimated through sightings and dung counts. The desired deer population can then be worked out based on the habitats present, the results of impact monitoring and known breeding rates, leading to a decision on the numbers of males and females that need to be culled. Through a cull, stalkers are also able to remove poorer weaker and older members of the herd, resulting in a stronger, healthier deer population. Deer are culled in accordance with legal requirements and accepted codes of practice ensuring animals are culled humanely. Most culled deer enter the food market as venison. There is legislation aimed at ensuring that carcasses are handled 8 their commitment and priorities as an integral part of their management of deer. The principles of the accord are: ■ A sustainable and balanced population of wild deer ■ A humane, responsible and sensitive approach to the management of wild deer 10 Recorded deer vehicle collisions 2000-2007 ■ An experienced and knowledgeable capability in deer management ■ An informed public understanding of deer management ■ A partnership approach to reducing the adverse environmental and economic impacts of wild deer To enable landowners to implement sustainable, landscape scale deer management, the DI provides a range of advice and support for deer population and impact monitoring, Best Practice standards, awareness raising and venison marketing. The DI has produced a comprehensive set of Best Practice Guides available on their website. 10 11 Managing deer in the Cotswolds Issues and impacts Habitats and land use Many Cotswolds woodlands (a significant number of which are small ancient woodlands particularly vulnerable to damage from deer) are suffering from the adverse impacts caused by high densities of deer.
