We have recently completed a tree climbing and aerial rescue course with 2 of us now in the company qualified to climb and inspect trees. This is particularly useful when we find trees with cracks and crevices that have potential to support bats. Often this is associated with road works or new developments.
Rather than rely on activity surveys alone in the summer months we can get up close with torch and endoscope and look for evidence in such features. The LANTRA, City and Guilds and NPTC certificates where hard won with 6 days of climbing and assessment.
All 10 species of bats found in Scotland will use trees to roost with the Soprano and Common pipistrelle bats perhaps the most commonly found there. Others such as Brown long-eared and Natterer’s bats will also use tree roosts. With many of the older and more rotten trees, providing suitable roost sites, in decline the provision of bat boxes can help to replace roost sites lost over the years.
Modern bat boxes made of woodcrete are perhaps the most versatile offering roosts with more stable temperatures for summer and winter roosting bats.
