Horley Conservation Group

Horley Conservation Group – Bat Walk, September 2016

As members of the Surrey Wildlife Trust, Horley Conservation Group is given access to one free educational activity per year. This year the group decided to invite Laura Ashfield to host an evening devoted to Bats.
After a night and day of heavy rain the sun came out in time for a group of us to gather at the Farmhouse pub to meet Laura Ashfield from the Surrey Wildlife Trust with the hope of finding some of our local bat population.
Laura started off by giving us a very interesting talk on bats and their lifestyle, complete with Laura’s rendition of what the different bats calls and eating sound like!

5 interesting bat facts

  • Bats wings are made up of their fingers with the wing skin, connected between the finger bones

  • Bats hunt at dusk (from approximately 20mins before sunset) for a few hours then have a rest and hunt again just before dawn

  • They eat on the wing grabbing insects from the air and munching them there and then

  • There are 18 species of bats in the UK (17 breading), which is almost a quarter of our mammal species

  • Common Pipistrelles weigh just 5 grams (same as a 20p piece), but can eat 3,000 tiny insects in just one night!

What we found.

Laura handed out bat detectors, clever devices that enable humans to hear the bats’ high frequency calls, which are normally beyond the range of human hearing. 
We then ventured out into the surrounding woodland and lanes, to see what we could see or rather hear.  Laura explained that the bats had probably not been out that morning.  Insects, their prey, don’t like the rain and it had been raining for the last 12 hours.  So we had a good chance of seeing them that evening. 
We started off with a walk around Tanyard Pond.   Different bat species are different sizes and make different calls so a trained ear like Laura’s is able to identify which species we could hear.    With our detectors tuned to 25kHz we were able to pick up a small number of calls of the Noctule bat.  This, the largest British species, is usually the first to appear in the evening.   
We then walked along Langshott Lane and out into Tanyard Meadow where by the large oak trees our detectors at 45kHz went wild with the calls of Common Pipistrelle and Soprano Pipistrelle bats – complete with the wetter slapping sounds of them eating.      
Laura then got us to turn off our detectors and listen to what to our human ear was silence, but we now knew was alive with higher pitched activity. After briefly crossing the brook and hearing more calls, we walked back through the Meadows and up Lake Lane to the pub, a thoroughly enjoyable couple of hours after we had met. 

What you can do to help

Bats are wonderful little creatures that often live in close proximity to us, using our gardens as an important source of food, water and shelter.  As bats’ natural habitats are becoming rarer our gardens, which together cover a greater area than all the National nature reserves, provide an important habitat for them. There are a number of simple steps that the Bat Conservation Trust recommend to help turn your garden in to a bat haven:
  • Plant night-scented flowers
  • Build a pond
  • Let your garden go a little wild
  • Put up a bat box
  • Create linear features i.e hedgerows/treelines
  • Reduce or remove artificial lighting
  • Keep cats indoors at night 
At 3,000 insects, hopefully mosquitos, a night, I aim to make my garden as bat friendly as possible!

Thank you to Laura for a wonderful evening.

Update January 2016
Whilst most people were still recovering from Christmas and New Year celebrations members of the Horley Conservation Group were busy at work.  With snow laying on the ground a team of volunteers made their way to Emlyn Meadows to work off some of the extra calories taken in over the festive season.  The team cut back blackthorn that was encroaching on both sides of the style and on the pond.  The pond area itself  was cleared of rubbish and had a substantial amount of vegetation raked out.  You can see the team at work in the attached pictures.
The next task is on February 20th at Langshott Woods when some of the Rhododendron growth will be cut back and burnt.
Our proposed task diary for the first half of 2016 is shown below so please feel free to turn up on the day – suitably dressed down!

Our AGM will be held on the evening of Monday 22nd February starting at 6pm at Trinity Oaks School. We are looking forward to a very busy and challenging year which will hopefully include the launch of a group website, progress on the development of a community orchard facility, attendance at the town carnival as well as more tasks to make our area a nicer one to enjoy life in.
