Out of season deer control on Scotland’s national forests and land
Our deer management activities
Recognising that deer are a valued and important element of Scotland’s biodiversity, culling of deer is nevertheless a necessary part of managing the impacts of deer and keeping the ecological balance in check for the environment.
Sustained heavy browsing by deer prevents woodland regeneration, and this is currently the most widespread threat to the condition of woodland biodiversity in Scotland and could impact on the forest industry’s climate change mitigation measures including peatland restoration.
In December 2019 the independent deer working group report to government noted that the total deer population in Scotland could be approaching one million and highlighted the need for proactive deer management.
At any one time on Scotland’s national forests and land, there are up to 150 million young trees vulnerable to damage from deer representing millions of pounds of investment in public forests. To minimise the browsing impact of deer on trees and ground flora we therefore invest around £7 million per annum in managing deer on Scotland’s national forests and land.
In order to take an evidenced based approach to our deer management, we commission annual surveys of deer populations and impacts. Over a number of years, the trends in the survey data has been upwards in terms of increased populations and damage to trees and wider biodiversity.
Working in collaboration with others
We take a collaborative approach to landscape scale deer management with other land managers such as:
Scottish Environment Link
A collective organisation of 40 member bodies representing a broad spectrum of environmental interests, who recently provided the following comment on our approach to deer management.
"As environmental land managers we fully recognise the need for ongoing control of deer populations, and to address the climate and biodiversity crises. Natural predators of deer are extinct in Scotland. Deer numbers are far higher than is sustainable for nature to thrive. Without reductions in deer population, we will not meet native woodland expansion, peatland protection, and therefore carbon sequestration targets.
Forestry and Land Scotland (FLS) delivers first class deer management across the national forests and land, allowing deer and trees to co-exist. FLS also delivers high environmental and animal welfare standards, for example showing leadership in the sector with a decision to phase out the use of lead ammunition. This cull extension is necessary. We fully support FLS and have every confidence that the work will be carried out to the highest standards."
Highland Game Ltd
“Highland Game are an Authorised Game Handling Establishment (AGHE) and are subject to official controls enforced by Food Standards Scotland.
Every carcass received at Highland Game is inspected by a Food Stands Scotland Meat Inspector to ensure the carcass is fit for human consumption.
In our experience a carcass has never been rejected as unfit for human consumption due to age. A carcass would only be rejected due to Pathology, Contamination or Decomposition”
Association of Deer Management Groups
“The Association of Deer Management Groups welcomes the chance to comment on the early culling of females and calves from 1st September. ADMG would always encourage deer managers to undertake culls during the open season where possible which starts each year on 21st October for females and calves.
We accept that it is sometimes necessary to undertake early culling under Section 5(6) of the Deer Act to protect woodland from damage. ADMG stresses that where damage necessitates out of season culling all deer management must be done in accordance with Best Practice Guidance and avoids the orphaning of any dependent calves”.
Association of Deer Management Groups
“NatureScot regulate and oversee deer management in Scotland. This includes the licensing of out of season control to prevent damage to woodland, agriculture and protect public safety.
Deer welfare is key and NatureScot take into account the period of greatest welfare risk based on the dependency of young, which in Scotland is the period between the 1st April – 31st August. This period is based on commissioned research into birthing and weaning dates of all species Scotland wide. During this period strict controls are in place when female deer can only be culled under a specific authorisation from NatureScot. These are only granted in exceptional circumstances.
Out with this period of highest welfare concern from 1st September any out of season control can only be undertaken under General authorisation (for enclosed woodland and improved agricultural land) or specific authorisation for other land types which are issued and conditioned by NatureScot.
Everyone controlling deer in Scotland is expected to do so in line with published Wild Deer Best Practice Guidance which outlines how deer welfare is safeguarded when culling and allowing land managers to effectively manage deer populations and their impacts.
There is a continued need to ensure damage by deer can be addressed to support climate, biodiversity and economy priorities, whilst ensuring deer welfare is fully taken into account. NatureScot consider Forestry and Land Scotland requests for out of season control licenses in line with licensing guidance”.
An evidenced based approach
Along with monitoring deer impacts on biodiversity FLS also monitors deer populations (density). A variety of methods are used to do this but dung counts is the primary method.
Over the past 5 years approximately one third of Scotland’s national forests and land have been surveyed. The mean average deer density in these survey areas have ranged from 4.2 deer per km2 to 64.7 deer per km2. The FLS target range as published in the FLS deer management strategy in 2014 is between 2 and 7 deer per km2. Of the land surveyed in the last five years, 89% has deer density well above this widely accepted target to help protect biodiversity from negative deer impacts.
On Scotland’s national forests and land, FLS has a target of not incurring more than 10% deer damage to young trees. In 2020 the 3 year rolling average of damage impacts was 18% for the leaders on young trees, i.e. trees planted for 1 year in the ground. This is well above our target. The regional variation for damage impacts ranged from 10% (up 5% from last year) to 30% (up 1% from last year) in 2020. Results at site level in 2020 ranged from 0% to 99% damage of young trees.
Out of season culling
To manage deer populations through reduced reproduction it is important to carefully manage female deer populations in particular. In doing this, over many years FLS has conducted out of season shooting of females under authorisation from NatureScot in relation to the Deer (Scotland) Act 1996 (as amended). These authorisations are widely used by other land managers to prevent damage by deer and are issued subject to adherence with best practice guidance found on the Wild Deer Best Practice Partnership website.
To manage the increasing numbers of deer and their negative impacts on the environment we work within the legislative framework of the Deer (Scotland) Act (as amended) to control both their numbers and impacts.
In 2019/20 NatureScot issued 254 section 5(6) out of season authorisations of which 12 related to FLS. A further 4 ‘female only’ authorisations under section 5(6) to cover the period 1st April to 31st August were issued by NatureScot and of this figure none were related to FLS.
All FLS rangers and contractors understand the need to cull young dependents first before any mothers. They operate under the following guidance: “when culling adult female deer prior to the start of the official open shooting season, all efforts should be made to cull associated juveniles first. If in any doubt about leaving a dependant young, then the adult female should not be culled”.
FLS proactively monitors culling operations and as such has confidence that when best practice is followed under these legal authorisations then there are no deer welfare issues. All deer controllers operating out of season on Scotland’s national forest and land are registered with NatureScot as fit and competent to undertake this activity.
We fully recognise that deer control is a difficult and very sensitive subject which arouses strong differences of view and some will find the process unacceptable. Nonetheless FLS follows Scottish Government policy, has the consent of the licencing authority NatureScot and follows best practice in implementation.
