The second phase of the otter holt build is now complete,
and all that is left is to pin the structure down in-case the flood waters
rise. The hexagonal, chambered structure was roofed with brash, waste timber
and turf to create a non-intrusive holt for any resident otters – Lois, David
and Dan are pictured standing outside the holt. A camera-trap was placed near
the entrance so any subsequent use can be monitored – check back to the blog to
see if the otter’s occupy their fancy new home!
In addition, students carried
out some water quality testing by ‘kick-sampling’ a gravel riffle and
identifying macro-invertebrates found (pictured). Some species are more
tolerant of pollution than others, but thankfully clean water indicators
including stoneflies were present.
