We recently undertook a series of trapping sessions
in which we attempted to discover which small mammals were present
in the Boat of Garten area. This survey would complement work
already done on owl pellet analysis and would form part of the
on-going biodiversity audit of Boat of Garten. Licenses were obtained
from SNH and training in the use of traps was provided for those
taking part. Six trip traps were used in the first session after
which we acquired four Longworth traps bringing the total to ten
traps. A summary of results is shown below.

Tawny Owl Survey
This is one of the surveys organised by the British
Trust For Ornithology (BTO). One simply goes to the centre of
a tetrad (a set of four one-kilometre squares) and listen for
ten minutes within the two hour period after sunset and listen
for tawny owls. The survey is done in the autumn when young
owls are being driven away from their parents' territories so
there is a lot of calling going on. This is what we found in
our designated tetrads within the OS Square NJ02
