Finally some good news for bat licences !  The bat queue seems to be declining and the delays are down from four to three weeks. Not brilliant, but better than nowt. Our forecast is for no improvement in the immediate to near future seems to have been wrong ! We don’t have May data for newts, cos we are too busy doing surveys still.

There are still staff shortages within the species protection teams, so the reduction must be down to the effort of the staff. We suspect that they will now be given a large pay rise in recognition of their efforts.

Natural England delays remain in reviewing European Protected Species Licence applications. If you need to gaining a licence and how it might affect your project, please contact us as soon as possible.

The following are based on ‘New’ Application processing time during the four week period 06th April 2015 to 08th May 2015 :

Bat Update (as of 8th May 2015)

  • 202  ‘New’ Applications outstanding [ 368 on 6/4/15 ; 355 on 10/2/15 ; 279 on 22/12/14 ]
  • “New application processing time: Average delay of 14 days (44 days versus 30 working day decision deadline) [ Reduction from 47 days on 6/4/15 ; 48 days in February and 47 days in 22 December ]

Similar processing times were reported for Modifications and Resubmissions.

 

Great crested newt mitigation and translocation

When should I think about great crested newt mitigation ?

If you are planning on developing a site and have had an ecological survey to assess impacts to wildlife read on. The results of this survey have identified potential impacts on great crested newts in and around the proposed development area.  You need to start thinking about mitigation for great crested newts at this point. For example you may need to create new habitats offsite to offset any damage on site.

What happens if there are great crested newts in an area for proposed development?

You must apply for a European Protected Species Mitigation (EPSM) licence from Natural England (NE). There is no charge by NE for EPSM licenses, however, the development must pass three legal tests. The activity must be for a purpose of public interest (for example, for providing housing ). There must be no satisfactory alternative that will cause less harm to the species. The activity must not harm the long-term conservation status of the species.

Planning permission for any development of the proposed site should be granted prior to applying for an EPSM licence. Once a licence has been applied for, you can usually expect a licensing decision within 30 days, but NE is currently assessing a large volume of applications.

A mitigation strategy forms part of the licence application. This both safeguards the great crested newt population before and after works and prevents harm to the individual animals. There will be a legally binding Method Statement which will include methods e.g. for translocation to remove individual newts, and a timetable.  Although these can be varied if something unexpected happens, not complying with the licence is a legal offence, so they need to be well thought through.

Translocation

Sometimes it is not possible to retain newt populations within a development site. In this case they will need to be moved – known as “translocation” or trapping out.  Translocation of Great Crested Newts will always involve a licence application to Natural England.

In the application Natural England will want to see that :

– The translocation site is as near as possible to the original site. In general over a mile would be unacceptable to them except in exceptional circumstances.  This is because the mitigation needs to maintain the populations at a local level, but also due to the risks of spreading chytrid and other amphibian diseases across the countryside.

– Any ponds removed or adversely affected will be replaced, preferably at a least a 2:1 ratio, . This is based on the presumption that not all ponds will be successful for newts.  Sometimes enhancement of existing ponds is possible e.g. old overgrown ponds now unsuitable for newts. SUDS ponds or balancing lagoons are not suitable.  The pond needs to be specifically for the species.

– There will need to be new habitat created or enhanced at least equal in area to that lost and/or of a higher quality. Examples might include arable land being replaced by grassland or improved grass leys replaced by scrub and woodland.

– In general you will need a survey to see if there are newts already at the translocation site. Translocating newts into ponds with existing populations is not acceptable, as there is no net gain for the species, since they just compete with newts already there.

– The management of the site will need to be guaranteed “in perpetuity” – normally by a Section 106 agreement with the landowner.  This is clearly less complex where the land is within the blue line of the development site owner or even with the red line.

Trapping a site out can be a lengthy process and take over a year allowing for licence application and seasons.  Trapping will normally be for 60 suitable days, but with additional requirements for breeding ponds. Suitable days are normally during spring and autumn, when temperatures are warm enough but not too dry for the newts to move around. When conditions are not suitable ( e.g. there is no rain for several days or it is too cold ), then trapping nights become “invalid” and the period of time needs to be extended.  Thus 60 trapping nights could in reality extend over an additional nights say or be caught short by the autumnal frost or a summer drought.

Planning law says that the local planning authority have to assess whether a European Protected Species for a site is likely to be granted by Natural England ( e.g. Morge versus Hants and more recently Elsworthy Farm judgement ) prior to granting permission.

How does the licence work when developing a site?

You need to keep a copy of the licence on site, and you may be inspected by Natural England to see if you are complying with it – they can request to see this copy.  Certain works will be carried out or supervised by your licenced ecologist, but there will be other responsibilities resting on the client. Make sure all contractors coming on site are inducted on it, and stick to what it says. At the end of the works, you need to make a licence return to prove that they have been carried out, and monitoring of any new ponds is necessary to give some measure of success.

For great crested newt legislation, see this post.

How many surveys for great crested newts ?

We thought it helpful for clients to have set out what actual Natural England requirements are for licencing – how old your survey can be  – and how many surveys are necessary.

Natural England guidance

Natural England guidance on presently acceptable levels of survey effort is set out in their EPSL method statement form – which we present below – slightly tweaked.  This sets out both the type and age of data viewed as acceptable.  You can use the filters to find your project type.

This is our Excel table here : Great crested – survey effort and age

Deconstructing this gives some interesting insights about the age of data required, but also whether as to whether a full six surveys or repeat surveys are necessary.

Low impact licences and survey data

If we read through this table, you will find that low impact or temporary development can often use presence/absence data alone, which makes sense.  You may only need four instead of six visits ( or possibly only one if you find them first time ! ). Newt numbers decline rapidly away from ponds ( either the creatures are too unfit or simply due to dispersion effects ). The effect a long way from ponds can therefore be predicted as being low, based on their presence alone.  Far enough away and you can assume de minimus effects, and possibly avoid surveys all together.

The age of data is based on spring/summer survey seasons elapsed ( but see also later for a potential complexity here ):

Survey done Age of survey (before May[?] 2015)
March to May 2015 0 (before May 15)
2014 1
2013 2
2012 3
2011 4
2010 5
2009 6

So this year, data from the 2011 summer season is 4 years old, assuming you apply before end of May[?] 2015.  This also means that for some low impact schemes, older data will be helpful.  There are various caveats to this.

It is not 100% clear from the footnote on the NE guidance whether the age of the survey is the number of survey seasons missed, inclusive or exclusive of the present year.  It would seem more logical that 2015 data is 0 years old until March 2016, but in fact it appears to be 1 after May this year. However it would be impossible to survey, get planning and apply in the time period. We will take this point up with Natural England for clarity [ thanks to someone for pointing this out to me ].

What survey effort is most helpful ?

This raises for us an interesting question about proportionality and efficiency – what solution for survey effort allows most accurate information most efficiently ?

Given that most ponds are in the small or medium range and that large counts are generally from aggregation across ponds, should we focus more on the number of ponds involved and their functional nature ?

eDNA difficulties for presence/abscence

A difficulty of eDNA for results is that it shows us nothing of the pond’s function.

Four nocturnal visits will not only give a very good guide for impact assessment,  but also should generally reveal if the animals are breeding successfully and may turn up eggs or efts dependant on timing.

Many ponds around a breeding pond have occasional newts, but are not of high enough quality for breeding – this issue was never tackled by HSI.  Vice versa large numbers of males lecking at a pond indicate one thing.  Knowledge about successful breeding at a pond seems to us essential in stating the effects on the population.

Conclusions

So to return to the question only four surveys with presence or possibly even eDNA to prove absence could be sufficient for your needs, or you may be able to rely on existing older data. However really your consultant needs to have some understanding of population ecology to advise you on mitigation and obtaining a licence. Following guidance verbatim is not a good solution and could waste your money – sorry that slipped out.

With this in mind we advise you not to rely on this article for formal advice, but let us discuss with you how it applies to your suituation – please contact us directly if you have a licencing query or you have some observations about the article.

There is more Natural England advice on their website : https://www.gov.uk/government/publications/great-crested-newts-apply-for-a-mitigation-licence

New EPSLs – reduced paperwork

Natural England have updated their European Protected Species licence forms, reducing some of the paperwork burdens on applicants.

New application form for bats

There is a new EPSL application form, which we think makes a lot more sense.  We are not sure if it is editable in all versions of Adobe Reader, but you can certainly use Foxit.  There are seperate forms for <3 species and >3 species, with a lot of tick boxes replacing the need to repeat text in and squeeze stuff up. It should make it more accessible for clients and easier to complete, plus indicates that NE may be streaming licences into low and high impact schemes, which makes a lot of sense.

Applications for home improvements and small scale housing developments

The guidance on the need for a Reasoned Statement has changed, making it only necessary for more complicated applications.  This doesn’t imply that you don’t need a licence – simply that the paperwork is becoming more proportional to the situation.  You need to read the details, but this means no more 20 page documents justifying a loft conversion or putting in a dormer window from NPPF. It also may reduce the paperwork burden on barn conversions under Permitted Development rights.

The exemptions are below.

Exemptions for Bats

“The following categories of work for all bat species and their roosts*:
i. repairs and maintenance, roof replacements, loft conversions, extensions and renovations of existing domestic dwellings and associated structures (eg garages).
ii. small-scale housing developments, including those that may require the demolition of existing buildings (whether domestic dwellings or other types of building).
*Unless the population is of regional or national importance – in which case please contact Natural England (see below) to discuss whether a Reasoned Statement is required.”

Exemptions for Great crested newts
“The following categories of works:
i. repairs and maintenance, extensions and renovations of existing domestic dwellings and associated structures (e.g. garages).
ii. small-scale housing developments within the curtilage of developed or previously developed (brownfield) sites, including those that may require the demolition of existing buildings (whether domestic dwellings or other types of building).”

There are also similar improvements around applications to conserve and protect Listed Buildings, Scheduled Monuments and places of worship.

You will need to read the fine print to see if this applies to you or contact us for advice.

A very sensible development from Natural England.

Bat and newt licence delays – April

We thought an update of European Protected Licence delays for bats and great crested newts on our previous February stats article might be of assistance.

Natural England are still unfortunately experiencing delays in reviewing European Protected Species Licence applications. If you need to gaining a licence and how it might affect your project, please contact us as soon as possible.

The Natural England FCS test are also now processed and signed off at a regional level, which may have lead to some teething issues.  It has helped by improving lines of communication once an advisor has been allocated.  Generally discussion on allocation dates are “vague”, but once the licence is allocated and processed this is generally quick. As a corollary, then it is difficult for clients to plan with certainty when a licence will arrive, except at short notice.

Delays with bat licences have not worsened, but remain steady at around three to four weeks.  Hopefully newly trained staff should be assisting now, but our forecast is for no improvement in the immediate to near future.

With respect to Great Crested Newts, we would forecast that there will be additional delays, which are shown by the lengthening queue, due to the normal “spring surge” of new applications.

The following are based on ‘New’ Application processing time during the four week period 2nd March 2015 to 3rd April 2015 :

Bat Update (as of 6th April 2015)

  • 368  ‘New’ Applications outstanding [ Up from 355 on 10 February, 279 on 22 December ]
  • “New application processing time: Average delay of 17 days (47 days versus 30 working day decision deadline) [ No change from 48 days on February and 47 days on 22 December ]

Similar processing times were reported for Modifications and Resubmissions.

Great Crested Newt Update (as of 6th April 2015 )

  • 162 ‘New’ Applications outstanding [ Up from 52 in February, 19 on 22 December ]
  • “New” application processing time: Average delay of 5 days (35 days versus 30 working day decision deadline) [ 32 days on February, 37 days on 22 December ]

There were similar processing times for Modifications and Resubmissions.

 

Creating a bespoke boudoir for bats

As part of the re-development of a small brownfield site within Norwich, NWS were commissioned by RGW Portugal Ltd to undertake bat surveys of two small buildings. One of these was found to support low numbers of brown long-eared bats Plecotus auritus and soprano pipistrelles Pipistrellus pygmaeus, which were using the building for roosting in summer. The buildings needed to be demolished in order to create space for two new residential homes, and so NWS prepared a European Protected Species Mitigation licence for bats which was granted by Natural England.

NWS licensed ecologists supervised the demolition of the buildings in August, removing a roosting brown long-eared bat which was found along the central ridge beam and relocating this within a bat box which had been placed on a mature oak tree in adjacent woodland.

RGW Portugal Ltd were keen for an environmentally sensitive development and had included bike stores within the design to encourage the use of green transport. These features provided the perfect opportunity to create a bespoke bat loft for both species of bats to use. The loft was constructed above the bike stores, using a lined and tiled pitched roof to generate warm internal temperatures. Two carefully-placed bat access points were installed along the ridge and at both gable ends, allowing a number of entry points whilst reducing potential for light ingress and draughts. The ridge beam was formed using rough-sawn timber to create a suitable surface for bats to cling to, and bat batons were also installed along the inner walls to provide additional perching points.

The last features of the bat loft have just been installed this winter and NWS are hopeful to see use of this loft by bats when they return to roost in April.

 

New winter homes for great crested newts

Since 2000, NWS has worked on development sites that support great crested newts, and in 2014 successfully assisted Saffron Housing in obtaining a European Protected Species Mitigation (EPSM) licence for this species on a residential development in South Norfolk. Nationally great crested newts have suffered huge declines and so are protected by European and UK law. Norfolk is one of the species’ strongholds, with greatest numbers of breeding ponds found on heavy clay soils.

With great crested newts present in ponds around the area and using the grassland on site to move between these, the EPSM licence was required during construction to protect these amphibians and provide compensatory habitat.

NWS staff supervised the installation of “newt exclusion fencing” and carried out pitfall trapping to remove newts from harm’s way. Great crested newts only use ponds for breeding and spend the rest of the year on land. The team focussed the compensatory habitat on features suitable for use during this “terrestrial phase” and supervised the creation of what was dubbed “Newt Nirvana” by the developer:  a wildflower grassland with hedgerows and scrub.

A key feature was the creation of three earth and stone mounds, which newts will use

This hibernacula has a rubble/log base to provide crevices for overwintering newts and is covered with turf to create stable temperatures through winter

during winter, called hibernacula. Great crested newts hibernate when winter temperatures drop below 5oC, normally from October or November. They typically hibernate underneath logs, within mammal burrow or tree roots, and even in building foundations. The hibernacula on site were designed to provide a number of sheltered crevices using logs and rubble, topped with turf to prevent exposure, whilst also ensuring newts were safe from flooding. Here the newts can remain protected until they emerge in late February or March to begin breeding in ponds.

What bat boxes should I use ?

Bat boxes are something we have a lot of inquiries from clients about .

The type of bat box to use will depend on what species of bats you need to provide for or want to attract.  Brown long-eared bats will prefer boxes with large cavities, whereas pipistrelles prefer flatter boxes that they can squeeze up into.  Maternity roosts will often look for much larger boxes or in the case of Brown long-eared bats the use of roof spaces or attics.

However clients also want bat boxes to look pretty and fit the style of the house.

Many bat boxes are designed more for modern architecture than a renovated building.  For example Schwelger [http://www.schwegler-natur.de/index.php?main=produkte&sub=fledermaus ] have the biggest range of “concrete” boxes and their very helpful website contains pictures and specifications for what they look like in reality and how to fit them.  The bigger ones are surprisingly heavy and nearly the size of a postbox, an important consideration for aesthetics and safety.  They are widely available via resellers in the UK.

On buildings where appearance is very important, especially listed buildings, built-in bat boxes may be a better option. Soffit boxes are a possibility and bat boxes can also be built into walls, where there is sufficient thickness or a double skin arrangement with a wide enough cavity.  Both these options leave only a small external access slot, which looks a bit like a letter box.

Wildcare stock a wide range of bat boxes and can send you a very nicely illustrated catalogue quickly by post : http://www.wildcareshop.com/product/nest-boxes-artificial-habitats/bat-boxes.html

You may also wish to consider installing bat access tiles as an alternative provision for bats.

[Footnote : Liz from the Sales Team at Wildcare has told us there is a wider selection of Schwelger boxes on their website than in their catalogue at the moment if you want something specific.  ]
