Bat and ecological scoping survey in Swindon

Tuesday, November 8th, 2011

UES recently completed a bat and ecological scoping survey of a farm in Swindon. Our client has plans to demolish a number of buildings on site and convert other buildings for use as a hotel.

13 buildings were surveyed in total, of which 5 were identified as having high potential for use by bats. Low number of bat droppings believed to be long-eared species Plecotus were found in the internal roof spaces of the farmhouse. UES recommended further surveys on these buildings prior to the start on site to determine how many bats are present and how they are using the buildings.

All bats and their roosts are fully protected by law. Without detailed surveys you are at risk of destroying a bat roost or foraging grounds, which could have devastating consequences for the local bat population, and could land you with a fine or even a jail sentence and some very bad publicity.

During the survey UES recognised that the buildings and trees on site were all suitable for use by roosting and breeding birds, therefore any building works should be carried out outside of the breeding bird season (March to August inclusive) in order that breeding birds are not affected. If this is not possible then either a targeted breeding bird survey should be carried out or an ecological clerk of works appointed.

All breeding birds are protected under schedule 9 of the wildlife and countryside act 1981(as amended). Wild birds are protected from being killed, injured or captured. Their nests are protected from being damaged, destroyed or taken. Several species are included in schedule 1 of the act which gives them and their young protection while nesting.

The presence of protected species is a material consideration when a planning authority is considering a development proposal. The presence of protected species and the effect of the proposed development must be established before planning permission can be granted.

Bat scoping survey in Lancashire

Thursday, November 3rd, 2011

UES recently completed a bat scoping survey of a house and associated outbuildings in Lancashire. Our client has plans to demolish a number of buildings onsite and is applying for planning permission for a new build housing scheme.

The aim of the survey was to assess the site for the presence of bat roosts and bat activity within the structure of the buildings. The buildings were searched both externally and internally for bat presence and features associated with bat activity, as detailed in Bat Conservation Trust guidance (2007).

No field signs of bats such as droppings, feeding remains, rubbing or urine stains were found during the building inspections, and as such UES deemed that no further survey work was required in relation to bats.

However, house sparrows were observed breeding inside the building, and therefore mitigation and compensation measures were suggested in relation to breeding birds as ‘The Wildlife and Countryside Act (WCA) 1981’ states that all wild birds are protected. Under the WCA, it is an offence to kill, injure or take any wild bird, to take damage or destroy the nest of any wild bird, or to take or destroy the egg of any wild bird.

Bats and badgers in Buckinghamshire

Wednesday, November 2nd, 2011

UES conducted a full bat survey of a barn in Marlow, Buckinghamshire in September 2011. Our client plans to change the use of the barn from agricultural to a dwelling.

Low numbers of common species of bats were observed using the area to forage and commute. The species recorded were Common pipistrelle Pipistrellus pipistrellus and Soprano pipistrelle Pipistrellus pygmaeus.

During the course of the survey some evidence of badgers was found including feeding remains and a latrine. A single badger was also observed in a hole on the northwest corner of the barn.

UES are currently completing badger monitoring surveys of the site in Buckinghamshire using remote wildlife cameras. Remote cameras are ideal for badger monitoring surveys allowing you to set it up onsite and return later to collect your images. Remote cameras can be set to take pictures or videos regularly with the time lapse facility, or when it is triggered by an animal moving into the field of view. Either way, it gives a remarkable insight into the wildlife in the vicinity.

Bat survey in Cranage, Cheshire

Fitting a bat box

UES have completed a bat presence/absence survey at a site in Cheshire. Our client intended to demolish a building and so a bat survey was required in order to inform the planning process.

The building was searched internally and externally for signs of use by bats, and emergence and return roost surveys were carried out. The surveys found bats roosting in the boxed soffits of the building and also under the roof and ridge tiles.

UES recommended that a licensed bat ecologist be present during the demolition in case any bats were found within the building.  During demolition a male pipistrelle was found roosting under the roof tiles and so was carefully rehomed to a new bat box that UES had positioned on site.

UES volunteer for the Bat Conservation Trust (BCT)

Friday, July 15th, 2011

BCT runs a number of national, annual surveys to monitor the status of bats throughout the UK. These surveys form the National Bat Monitoring Programme (NBMP). UES volunteers with around 3000 others to collect essential data on bat populations every year.

UES is currently completing field surveys of 3 sites in Cheshire. Each survey involves walking a triangular route in a randomly allocated 1km square on two evenings in July, to record noctule, serotine, common pipistrelle and soprano pipistrelle bat activity. UES uses several pieces of equipment during a bat survey; bat boxes which can detect the echolocation calls of bats, and the Anabat system which detects bat echolocation calls and displays them visually on a PDA screen which makes recording of the bat calls and identification of the bat species much more accurate.

The NBMP is of great importance as UK bat populations have declined considerably during the past century due to building and development works affecting roosts, and the loss of feeding habitats and flightlines.

United Environmental Services at Bioblitz, Norton Priory, Near Runcorn Cheshire

Wednesday, June 8th, 2011

Stewart attended the Bioblitz event at Norton priory on Friday evening  to help with the bat surveys.

The event was organised by Cheshire Active Naturalists (CAN). The aim of the event was to record as many species of wildlife as possible on the site, with a target of 1000 species. Experts and specialists in many different field gathered at the site for the weekend event.

Stewart spent Friday evening recording bat species present on site . A total of six species of bat were found including common pipistrelle bats, soprano pipistrelle bats, Noctule bats, Brown long eared bats, Daubentons bats and whiskered / Brandts bats. Bats were seen to emerge from the buildings on site during the evening emergence survey. Most species of bats were recorded during the activity surveys around the canal and woodlands on the site.

The event was a great success for the CAN group and many members of the public attended a number of walks to search for species in the area. At the last count around 600 species had been recorded, but some samples were still being examined to determine the exact species.

Beavers could help to create bat habitat

Friday, January 21st, 2011

Beavers thinning out woodlands may help to create good quality feeding habitat for aerial hunting bats.

A study carried out by researchers from the University of Gdansk, Poland has shown that bats may be one of the species to benefit from the reintroduction of the European Beaver. The study showed that trees felled by beavers opened up the woodland and the number of aerial hunting bats increased. The bats also benefitted from the damming activities of the beaver which led to the flooding of areas of woodland, and an increase in the numbers of insect prey for the bats.

Bat surveys carried out by the research group indicated that the species which benefitted most were species such as common pipistrelle, soprano pipistrelle and nathusius pipistrelle and also the noctule bat.

Daubentons bats which are closely associated with water did not benefit as much as expected. This is possibly because daubentons bats like to hunt low over water using a reflected echolocation pulse to locate prey. The water in the flooded woodlands was quickly populated by aquatic plant species such as duckweed which scatters the echolocation pulse making hunting more difficult.

The reintroduction of the beaver could benefit many species such as the great crested newt.

Natural England granted wider powers to enforce breaches of wildlife legislation

Wednesday, February 3rd, 2010

Natural England

Flexibility

Defra have announced that Natural England will be granted more flexible powers to enforce breaches of wildlife legislation. The legislation applies to certain protected species such as the great crested newt, water vole, badgers and natterjack toads. The legislation also applies to all of our resident bat species.

Formerley Natural England had only three options available, these were

  • issue of warning letters
  • issue of caution
  • full criminal prosecution

New powers

Under the new powers regulators will be able to match the strength of the sanction to the seriousness of the offence and also:

  • Halt illegal activities
  • order the restoration of environmental damage
  • impose fines where legislation has been breached

Cheshire bat group at Beeston Castle

Sunday, January 31st, 2010

Cheshire bat group have visited Beeston Castle in Cheshire to inspect the caves for hibernating bats and and to fit bat boxes onto the trees surrounding the castle. The bat group are working with English Heritage at the site to make improvements to the quality of the habitat surrounding the castle. Stewart from United environmental services helped out with the tree climbing and bat box installation

The castle supports a colony of natterers bats as well as noctules and pipistrelles. The different bat species all use different areas and features of the monument and its grounds  in different ways, and at different times of year.

The caves were man made and the walls are very smooth with few faults which can support hibernating bats. An inspection of the caves by the bat group revealed a single hibernating natterers bat tucked into a small fault in the rock. Herald moths were also seen in the caves and are considered an indicator of conditions suitable for hibernating bats.

Fitting the bat boxes into the trees proved an arduous task as on the day it was snowing quite heavily. The bat group did manage to fit 18 boxes into the trees with a further 12 boxes to be placed in the trees and 4 to be fitted in the caves at a later date.

Installing Bat Hibernation Boxes in Cheshire

Wednesday, December 9th, 2009

Bat Hibernation boxes are fitted high in trees and this one was no exception.This mature beech tree was chosen because of its size location and stability.  Ropes were set up by Mike in order to climb the tree and then a small pulley was placed above the planned position of the hibernation box. Stewart then climbed the tree using the ropes. The pulley was tested for safety and then the bracket was nailed into position. The hibernation box which weighs 30kg was then hoisted up by Mike and Toby and hung in its final position roughly eight metres above the ground.

We hope to find noctule bats using this box next year as they were observed feeding very close by during a survey last summer. Soprano pipistrelles and Brown long eared bats were also recorded at the time and pipistrelles may well use the box when they find it. It is always a good approach to install extra bat roosts around any development even if no bats are to be affected by it. This can help all species of bats as they require many different roosts at different times of the year.

We also fitted hibernation boxes into the walls of the extension. And fitted bat access tiles into the new roof to allow access to the void beneath the tiles for crevice dwelling bats such as pipistrelles.
