Pale Pin-palp

Bembidion testaceum

Subject to the findings of the autecological review, re-introduce the species into catchments from which it has been lost (where these are suitable). The Rivers Tyne (Corbridge) and Monnow hold the most recently recorded populations and these should be assessed for their sustainability as donor populations for other locations which held the species in recent times and where suitable sediments are present. Consider ecological requirements of the species, suitability of site (e.g. subject to ongoing threats and/or climate change effects), timing of release and the need for ongoing habitat management. No information could be found on the feasibility of such re-introductions nor the techniques necessary for success.

Manage river habitats to create suitable areas of exposed river sediments, ideally through the restoration of natural river hydrology where man-made changes have resulted in increased siltation. Also address heavy poaching by livestock, although vegetation control might be necessary to maintain open conditions. Similar work should be undertaken to increase habitat extent and quality in existing river locations where feasible.

Supplement the existing EA review with further autecological study to help characterise the range of micro-habitats within which it is found, particularly location, extent and composition of river bank substrates, presence and effect of livestock and frequency and duration of inundation by flood waters. Identify the management requirements of optimal riverine habitats, as well as the pressures resulting from man-made changes to river hydrological dynamics and colonisation by invasive plants (e.g. Himalayan Balsam) which might result in further declines.
