The new licensing system for bats

Wildlife Legislation

As you all know, a range of species in England are protected by law; sometimes this is in the form of national Acts of Parliament and other times European Union wide regulations. Either way, dealing with them and advising upon them is the remit of Natural England (NE). One of NE’s roles is to regulate licenses for the purposes of development that will mitigate and reduce the impact on protected species such as the great crested newt (Triturus cristatus), the badger (Meles meles), the hazel dormouse (Muscardinus avellanarius) and bats (of the Chiroptera order). Though the badger is protected only by The Protection of Badgers Act of 1992 which does not have a European equivalent as this Act relates only to preventing blood-sport rather than conservation measures, the great crested newt and bats are covered by The Conservation Regulations of 1994, an EU wide piece of legislation; the new licensing system relates only to European Protected Species (EPS).

Development Mitigation Measures

For a development to remain legal, it has to put in place measures to mitigate for its impact on these species and this usually entails relocating them to a suitable location; each development requires a license for this as well as a licensed ecologist to carry out the work. To get this license, an application is required by NE and when additional information is needed this is requested via a Further Information Request (FIR). The downside of these requests is that they are required even for minor adjustments and that they take time (and time equals money!); last year this system was changed by NE for developments applying for great crested newt licenses to incorporate ‘annex’ licensing.

What Are ‘Annex’ Licenses?

The annex licensing system means that for any additionally required minor information and adjustments of license applications the wildlife advisors of NE can simply phone or email the developer or contracted ecologist (or any third party named by the developer or contracted ecologist); this cuts out the need for many FIR’s and in an 11 month period last year the need for 160 FIR’s for great crested newt applications was avoided. However, poor quality license applications still require the more formal FIR route as the additional information required is likely substantial.

But What About Bats?

As bats are covered under annexes II and IV of The Conservation Regulations of 1994, the changes to EPS licensing are set to apply to them this year. As there are 18 bat species in the UK, the greatest volume of FIR’s are generated by bat license applications, so the annex system should speed up the process. The new annex system was implemented for bats at the end of March 2014 and after the 1st of May 2014 the previous licensing system will become redundant; applications that use the former system will be returned to the sender. As of May 2014 this change will also apply to the hazel dormouse which is protected under appendix III of the Bonn Convention.

The importance of heathland and controlled burning

A recent visit to Bickerton Hill with Reaseheath College, introduced me to some of the management techniques associated with heathland habitats.

They are specialist habitats of huge importance that support a great diversity of wildlife. The purpose of our trip was to try to locate and identify male adder species, Vipera berus, who are emerging before the breeding season at this time of year. Unfortunately, no snakes were found, but examples of other species which depend on this habitat were.

The two species found illustrates the biodiversity of the area, the peacock butterfly and the common lizard.

Heathland habitats also support a diverse number of plant species such as bilberry, heather and gorse. These plants are specifically adapted to survive low nutrient levels and periodic drought or prolonged water logging. This is of huge importance, because the range of plant species that grow in these areas support a large number of invertebrate, reptile and bird species.

Management of heath prevents the process of succession taking place. Silver Birch (Betula pendula) colonise these areas quickly. They are a fast growing pioneer species, and if left unmanaged, will eventually develop into woodland.

Management techniques include cutting, grazing and burning. All have their pros and cons, but burning of heath has the biggest impact on grouse.

Grouse depend on the new growth of heather as they feed on the new shoots, they also rely on the cover for protection from predators and for nesting sites.

It is important that the heather is burned to set regulations and on a cyclical system, usually between 8 – 25 year cycles. Drier ground is often burned more regularly than wet ground. If areas are left unburned for prolonged periods, succession will begin to take a hold, and mosses, lichens and even birch saplings will begin to colonise. This will prevent the new growth of heather, so it is important to manage the cycles accordingly.

One issue relating to this method of heathland control is having the numbers of people in place to carry out the work. It is generally accepted that there are only between fifteen to twenty five burning days each winter, and on average the fires must be completed within twenty days. That equates to eleven fires of an average of 0.4ha every day. Since it takes two able men with all the correct equipment, and ideal conditions, a single day to complete 6 fires, to complete the required area in the given time is a challenge to say the least!

Employing more people at very short notice is not easy, and this leads to a genuine issue. If the programme is not completed, large areas remain unburned, which leads to an increase in degenerate heather.

Burning of large areas of ground, visible from great distances may appear a drastic measure on the face of it to some, but providing the burn is controlled, is an excellent management tool to create greater biodiversity, and habitat for all types of flora and fauna. There is legislation in place to prevent burning at certain times of the year. It can only be carried out between October and April, with some exceptions depending on location.

A range of tools have been used and developed to complete the job. In years gone by keepers would use an instrument known as a ‘besom’. “These were brushes made from birch saplings and twigs with a covering of wire netting, the whole bound tightly with soft wire.” (Phillips, 2012.)

Today, the tools for the job need to be more efficient at completing the task. Anyone who is serious about burning heather will use light, strong and well designed kit, which do not break and will not melt or catch fire. This will not only ensure the job is completed to a high standard, but more importantly that it is done safely, and will result in the reduction of fires getting out of control.

Controlled burning

This technique is a skill, and should not be undertaken without relevant experience. Without this management technique, we wouldn’t have the numbers of grouse, or large areas of heathland that make up large parts of our country today. Careful consideration and planning must be undertaken before every burn. Weather, and special times of the year such as bird nesting, correct equipment, man power and fire breaks all need to be outlined prior to commencement of a job.

Heathland management by controlled burning has been practiced for many years, and providing it continues, will provide large areas of rich biodiversity, support large numbers of grouse and in turn allow large areas of game management to continue long into the future.

Deer teeth

Judging a deers age by its teeth

There are six species of wild deer in the UK and many students currently studying game and wildlife management or countryside management at Reaseheath College will be involved with the management of these deer in their future careers.

They may be required to accurately age a deer to ensure that they are conforming to the appropriate management or cull plan.

Deer teeth

This is part of the collection of lower jaw bones from, mostly from Chinese water deer (Hydropotes inermis) but the second from the top is from a year old roe (Capreolus capreolus) doe and the bottom fragment is from a muntjac (Muntiacus reevesi) buck. The way to estimate the age of a deer is to look at the eruption of the teeth, discounting the incisors at the front of the jaw, most of which are missing in these photos, each lower jaw in an adult deer should have six teeth.

The rule is simple; if all the molars (the three rearmost teeth) are not erupted and the third premolar (the third tooth from the front) has three cusps the deer is juvenile.

As a guide roe deer should have all their adult teeth, i.e six teeth on each side of the lower jaw and a two cusped pre-molar by 13 months of age, Chinese water deer and muntjac mature slightly faster and should have all these teeth shortly before they are 12 months of age.

A full set of adult teeth, notice the third premolar only has two cusps and all molars are fully erupted.

Trying to judge the age of adult teeth is harder, the wear and tear on the teeth gives an indication of age but this depends on a deers diet and local conditions.

Lightly worn teeth, notice the molar to the extreme right is not fully erupted (this is a juvenile deer).

Heavy wear on a full set of adult teeth. notice how the cusps of the teeth are almost completely worn away, this indicates that this deer was much more mature.
