Tenders Are Invited For Remapping Of Eelgrass Sites In Outer Oslofjord

remapping Of Eelgrass Sites In Outer Oslofjord . Descriptionmarine Underwater Beds Dominated By Common Eelgrass Zosteramarina Was Mapped In The Oslo Fjord Under The National Program For Mapping Biological Diversity &Ndash; Coast, In The Period 2007-2010. In Recent Times, Several Of These Have Been Re-Mapped, But There Are Still Many Localities Where The Status And Development Since That Time Is Unknown. The Purpose Of This Announcement Is To Increase The Knowledge Base On The Development And Condition Of Common Eelgrass And To Contribute To Knowledge About Variation In Quality In Locations In The Outer Oslofjord (The Swedish Border To Agder And Outside The Drøbakterskele). It Must Also Be A Basis For Future Assessments Of The Development Based On The Use Of New Methodology. The Starting Point Is Localities That Are Already Registered In Naturbase And Have Not Been Examined Since 2012. Within The Nature Type Eelgrass Communities There Are Different Designs, In This Work It Is The Design Normal Eelgrass That Will Be Investigated. Locations Within Value Categories Very Important And Important Must Be Included In The Surveys. About 270 Locations With Common Eelgrass In These Two Value Categories Are Registered In Naturbase. Some Meadows May Be Too Small To Be Classified In Condition, Or Have Disappeared. Some Locations Can Be Excluded Because The Area Is Built-Up. Previously Mapped Eel Grass Beds Must Be Examined In The Field And Mapped And Condition Classified, Setting A Methodology For Monitoring And Calculating The Eel Grass Index Described In Guideline 02:2018 (Direktoratsgruppenvanndirektivent 2018). In Addition, The Extent Of The Site Must Be Recorded And Any Changes In The Size Of The Eel Grass Sites Assessed. A Sample Of 20% Of The Investigated Localities Must Also Be Mapped In Accordance With The Norwegian Environment Agencys Instructions For Mapping Marine Habitat Types According To Nature In Norway (Nin). Changes/Developments Must Be Documented And Described And The Locations Condition Classified In Accordance With The Water Regulations. Estimated Budget For The Surveys In 2026 Is Nok Nok 2,300,000
