Suitable habitat was defined according to previously identified habitat criteria based on substrate type and hydraulic conditions, and survey was undertaken from a boat, combined with bankside surveys. The results of the survey found that suitable shad and lamprey habitat were present in the River Teme, however almost no suitable habitat was identified in the lower River Severn. Subsequently, potential monitoring locations were identified within the River Teme, but it was not possible to identify specific monitoring sites in the Severn. Notwithstanding that no specific shad or lamprey habitat was identified within the River Severn, it may still prove an important habitat for these species due to its large spatial extent. Therefore sampling strategies for the River Severn are discussed, but due to the lack of species specific habitat and the likely low densities of fish, high intensity surveys for the species of interest are likely to be required APEM Ltd manchester@apemltd.co.uk originator Marine GI Data Natural England Natural England +44 (0)300 060 3900 +44 (0)300 060 2356 Foss House, Kings Pool, 1-2 Peasholme Green York YO1 7PX enquiries@naturalengland.org.uk custodian notPlanned Marine Environmental Data and Information Network Habitats and biotopes Species distribution GEMET - INSPIRE themes, version 1.0 2008-01-06 revision Fish abundance in water bodies Habitat extent Habitat characterisation SeaDataNet P021 parameter discovery vocabulary 2009-11-16 revision OGL otherRestrictions OGL English biota biota SeaDataNet vertical extent keywords 2010-01-01 revision inapplicable -4.7292 -1.7080 51.1336 52.7520 2014-01-01 2021-11-10 Marine GI Data Natural England Natural England +44 (0)300 060 3900 +44 (0)300 060 2356 Foss House, Kings Pool, 1-2 Peasholme Green York YO1 7PX enquiries@naturalengland.org.uk distributor http://publications.naturalengland.org.uk/publication/5681495520313344 A link to the web service or dataset dataset The habitat survey technique used was based around the Environment Agency’s Fisheries Technical Manual 4: Restoration of Riverine Salmon Habitats (Hendry and Cragg-Hine, 1997), devised by APEM. To enable mapping of both river banks and the mid-channel habitat, the survey was undertaken by making direct observations from a boat within the river channel.
