A fleeting encounter 🦉

It’s not just bats we are on the look out for. We pick up various creatures of the night during our evening surveys, including this tawny owl!

Fantastic news having this garden come to Clydach. Well done

Re-roofing at massive houses requires some very impressive scaffolding!

The marvellous roof is home to brown long-eared bats and Myotis bats we found roosting inside the loft space, so we were careful to make sure that the bats were protected while all work was undertaken. We made sure there were no bats in the loft prior to the commencement of work, and were on site during the soft-strip of the roof in case any bats were encountered.

When we returned to inspect the mitigation, one of our furry friends was seen flying through the loft space, which is an excellent sign that they have adapted to their new access slates and new roof quickly!

It’s everyone’s favourite season - Bat Season!

This bat was found under some roof skates during a soft-strip of a roof that proved to be a popular bat roost during our activity surveys last summer. A grand total of six pipistrelles were found in the roof space during the development. Those that didn’t immediately fly away were safely captured and transported to a bat box on site to roost for the rest of the day.

Plentiful access was installed into the new roof once repairs were completed. We will be returning to conduct post-monitoring surveys in the coming years to see how the bats take to their new access points!

When you set up trail cameras outside a bat roost, you expect to see more bats than canines 🦇🦊

A recent PRA in the sunshine! How would you rate the roosting potential of this property?

A little insight into the work we do outside of bat surveys: site enhancement. This winter, our team were out in the cold digging an 100m long trench to plant a hedge that, with time to grow and mature, will provide a dark zone for bats to commute to and from their roosts!

This time of year, we are focused on site supervision works. We are on site at the heart of the development when bat roosts are being altered or destroyed to ensure that if bats are present, they are safely handled and removed from the potentially dangerous situation. This is an essential part of ensuring the bat licence is fulfilled legally. With the first signs of spring on the horizon, we are very much looking forward to getting back into the swing of things in the coming bat season!

Batty Christmas everyone!

Infrared and thermal cameras are an essential part of our bat survey arsenal. When it gets too dark for our eyes to see, the cameras can see for us. Video playback allows us to pinpoint exact access points and obtain an accurate count of the bats emerging from whatever building or structure we are surveying.

So, how do we decide where to position our cameras?

Firstly, the Preliminary Roost Assessment we conduct helps determine potential bat access points. We ensure that cameras clearly capture those access points as these areas are where we are likely to see bats emerging. Potential access points are a priority to capture, but we also ensure all aspects of the building are covered and try to ensure we have a com-lete view of the property. This isn’t always possible - there may be odd angles that make it difficult to have the whole building in view, or a high roof that is difficult to film from the ground level. There is trial and error and lots of adjustments before we turn them on for the evening.

Between surveys, we review footage. We confirm bat access points, and also identify areas that our cameras did not capture. This helps inform our subsequent surveys, allowing us to adjust our cameras if necessary or bring additional ones that focus on the access points and really hone in on where the bats are emerging from.

By the end of our set of surveys, we have gleaned a thorough overview of the bat presence of the building - the species, the numbers, and the access points.
