What chemicals can I use in bat roosts ?

Natural England guidance on chemicals not affecting bats is hard to find on gov.uk. We have uploaded a copy of “Natural England Technical Information Note TIN092 Bat roosts and timber treatment products” [TIN092_Bat_Friendly_Timber_Treatment], which is the First edition dated 15 March 2011. This gives a list of those commonly available products currently approved as remedial timber treatment chemicals and products in bat roosts. This was an update to the information in the 3rd edition of the Bat Workers Manual.

We know the list is not comprehensive. If you can’t find what you are looking for, you may be best to get us to ring Natural England on your behalf.  They are very friendly and generally able to make a quick response on the subject.

Consultation shake up for great crested newts

There may be a big shake up in the approach to Great Crested Newts on development sites. Natural England is seeking views about changes in licencing around Great Crested Newts mitigation. Read their document here

The policy proposals are quite a radical change and focus on spending more money on habitat creation to secure long-term populations of newts and less on consultants fees to move them. They are related to the Woking pilot :
http://www.woking.gov.uk/environment/greeninf/newt/gcnpilot/gcnpilotconsult

They have 4 new policies for licences they feel could benefit European protected species whilst “improving flexibility for developers” :

  1. Greater flexibility when excluding and relocating EPS from development sites [ not always having to fence or trap out sites ]
  2. Greater flexibility in the location of newly created habitats that compensate for habitats that will be lost [ whether these are nearby or not ]
  3. Allowing EPS to have access to temporary habitats that will be developed at a later date  [ avoids developers excluding them for worrying about colonisation ]
  4. Appropriate and relevant surveys where the impacts of development can be confidently predicted [ avoids unnecessary surveys that add no greater clarity but additional costs ]

You can comment on these proposed new policies for European protected species licences – the consultation closes at 7 April 2016 5:00pm : https://www.gov.uk/government/consultations/wildlife-licensing-comment-on-new-policies-for-european-protected-species-licences

Schedule 9 invasive plants and development

Schedule 9 plants are invasive and generally need controlling on a development site. After talking to a client about yellow archangel, we thought a list of schedule 9 would be helpful. It is an offence to “plant or otherwise cause to grow in the wild invasive non-native plants listed on Schedule 9 of the Wildlife and Countryside Act.”

A lot of the most invasive are aquatic or live in marshy environments e.g. Crassula helmsii, but brownfield sites also harbour species such as knotweed.  We can advise on control methods to incorporate into construction management for you.

What is Section 28 permission ?

Section 28 is the way in which Natural England offer permission for acts that might potentially damage SSSIs.  It refers to the 1981 Countryside & Wildlife Act, which was amended by the Countryside Rights of Way Act 2000 and the Natural Environment and Rural Communities Act 2006.  It applies to individual landowners as well as public bodies such as Secretary of State, government departments and agencies, local authorities and statutory undertakers ( water, gas, drainage boards ).

The Act requires people who own or occupy of SSSIs to ask Natural England for permission to carry out operations that may “damage the special interest of the site”.  These operations  (also might be called ‘Operations Likely to Damage’ (OLD) or ‘Potentially Damaging Operations’ ( PDOs) are listed for each SSSI. They might include drainage, excavation or change of use.  [Normally where the site is already under a management agreement or management plan agreed with Natural England then the consent will be implicit in these plans. ].

There are three separate strands, based on who is applying and why :

1. Consents (= Section 28 E)

– applies to SSSI owners/occupiers of an SSSI asking permission to undertake works, including a public body where it isnt part of their functions e.g. where they own a SSSI.

2. Assents (= Section 28 H)

where public bodies are carrying out their functions such as  and they need to undertake works on a site that includes an operation identified in the SSSI notification as likely to damage.

3. Advice (= Section 28 I)

– where a public body, such as a local authority, has powers to grant permission for others to undertake work on an SSSI.  Natural England can advise against giving permission for such operations that may “damage the special interest of the site” or advise that conditions should be attached.

Natural England may grant consent, with or without conditions, or refuse consent on operations, where it is not “compatible with furthering the conservation and enhancement of the special interest of the site”.
