Site survey of trees on the Meadows

Simon Chapple and I met with Peter Davidson, one of the City of Edinburgh Council’s Park Rangers, to look at the options for installing our Audio Capture Devices (ACDs) in trees across the Meadows. Although there was a fresh wind, we were fortunate that it was a clear, sunny day to carry out our survey.

To start off, Simon gave a brief introduction to his ‘bird box’ enclosures and electronic kit, and explained how they would be attached to the trees using bungee cords, plus a padlocked cable for security.

We then did a quick tour of parts of the Meadows where we could see that we were in range of the newly-installed WiFi Access Point, appropriately enough named ‘organicity’, The main challenge was to find trees with branches in the ‘goldilocks’ zone: high enough for the ACDs to be out of harm’s way, but not too high for us to change the battery if necessary. (No, we haven’t yet got the point where we can use solar panels or tap into the power source of lamp posts!) Another constraint is that we need to avoid trees which have been marked as possibly suffering from Dutch Elm Disease, though fortunately that doesn’t seem to be too prevalent on the Meadows.

We concluded with the happy feeling that there was a good number of trees that we could use when we are ready to launch the devices in public.
