Comments:
A couple of dead chub were noticed at this pond, though live carp were seen in the middle of the pond and sticklebacks were caught in the pond net.

The perimeter of the pond was walked and the aquatic species found were noted.

A 3 minute sweep sample with a pond net was collected again around the perimeter of the pond. The sample was then analysed on the bankside and the invertebrates noted. We did not note abundances only presence.
