At 50m intervals Method & a ‘spot-check’ is conducted to record specific details about bank and channel Standard of physical attributes, man-made modifications, land uses and vegetation Assessment structure. General information is recorded in the 'sweep-up' section, where features and modifications are recorded as absent, present (0-33% of the site) or extensive (>33% of the site). Habitat components such as trees and associated features, invasive species, and bank profiles are recorded in this section.)

APPENDIX 5

BIODIVERSITY MONITORING SCHEDULE – Alkmaria romijni (Tentacled Lagoon-worm) Survey

A baseline survey for the Tentacled Lagoon-worm (Alkmaria romijni) at various locations in the Medway Estuary Marine Consevation Zone (MCZ) to identify the spatial distribution of the species. Assessment

Type The Water Company shall discuss and agree in writing with the Environment Agency any proposed changes to this monitoring schedule in advance of carrying out any of the survey work.

A licence to undertake this survey will be required from Natural England.

This survey design is based on the best available knowledge regarding the habitat preferences and salinity tolerances from the River Thames of this species. The existing records for this species were also incorporated into the survey design.

Grab samples need to be taken below the spring low tide mark at each location using a suitable vessel, samples should be taken just below the low Monitoring tide mark and not from the central river channel. Method & Standard of A single grab sample (0.1m2) will need to be taken at each site for Assessment macroinvertebrate analysis and another grab taken for particle size determination, any grab that does not collect at least 1/3 of a bucket sample will need to be repeated at least twice before that site is abandoned. Care should be taken regarding handling these samples as the species lives in the surface 3-5mm of sediment.

Samples will need to be suitably preserved and transported to an appropriate laboratory for analysis. The laboratory will need to be a participant in the national marine AQC scheme and samples sieved over a 500µm sieve.

Frequency of One baseline survey at each location during the validity of this Drought Permit monitoring (up to 31/03/2018.)
