Ponds, Pools and Lochans

3.2 Conservation assessment methods using wetland plants and aquatic macroinvertebrates

Standard conservation assessment methods have been developed by Pond Action for plant and aquatic macroinvertebrate communities of ponds. These assessment methods are based on the plant and invertebrate survey methods developed for the National Pond Survey (NPS) (Pond Action, 1998). Standard wetland plant and aquatic invertebrate species lists are available from Pond Action. These provide information on species status (common, local, nationally uncommon or Red Data Book), including rarity values for the calculation of Species Rarity Index scores.
