Environmental Services - Recording Of Amphibian Species With A Special Focus On The Species In Appendixes Ii And Iv Of The Ffh Directive Near Naumburg - 2027. Mtb Designation: Naumburg (4836) And Camburg (4936) ... The Aim Of The Service Is To Record The Amphibian Species Group In As Many Suitable Water Bodies As Possible Within The Respective Measurement Table Sheet (Mtb), Whereby Priority Is Given To Water Bodies With High Potential For Species In Annexes Ii And Iv. For The Recording, At Least 3 Inspections Should Be Carried Out Per Measuring Table Sheet, Whereby 4 (Preferably Connected) Field Days (With 8 Mapping Hours Each) Must Be Completed To Inspect A Complete Measuring Table Sheet (Corresponds To One Field Day Per Visit And Mtb Q). For The Entire Recording (At Least 3 Ascents) There Are 12 Full Off-Road Days Available Per Mtb. These Must Be Completed In Full In Any Case - Regardless Of The Number Of Mapped Bodies Of Water. Due To The Size Of The Study Area And The Z. T. Short Population Maximums Of Selected Species In The Waters (Explosive Spawners) Should Be The Above. Field Days Can Be Divided Among Several Detectors Working In Parallel. An Exact Number Of Bodies Of Water To Be Recorded Is Not Specified, As This Is Based On The Above. The Time Required Can Vary Greatly Depending On The Local Conditions (Size Of Bodies Of Water, Travel Distances Between Bodies Of Water, Etc.) And In General, The Maximum Of The Above Mentioned. Use Of Time To Record Possible Bodies Of Water. However, 25 Bodies Of Water To Be Mapped Per Measuring Table Sheet Should Be Considered An Absolute Minimum (Corresponds To 6.25 Bodies Of Water Per Field Day). With Regard To The Selection Of Water Bodies, Care Must Be Taken To Ensure That They Are Distributed As Evenly As Possible Throughout The Entire Mtb And The Mtb-Q And That There Are No Mapping Gaps. In Advance Of Mapping, Corresponding Work Maps (Or Digital Maps) Should Be Created For Each Mtb Or Mtb-Q, On Which All Pre-Numbered Bodies Of Water That Can Be Identified Using Geodata (Btnt, Osm Water Data, Etc.) (Mtb-Wise Consecutive Numbering In The Scheme: “3437-001”) And, If Applicable, Known Species Occurrences Are Shown. The Corresponding Data Will Be Made Available By Lau After The Contract Has Been Awarded. With The Help Of These Maps/Digital Bases, The Mtb Can Be Systematically Walked And Mapped In The Terrain. ... During The Inspections, The Usual Standard Methods For Recording Amphibians (Spawn Searches, Interrogations, Visual Observations, Night-Time Illumination Of The Water Banks, Search For Larvae, And If Necessary Catching Fish Traps) Should Be Used. All Amphibian Occurrences Must Be Documented Species-Specifically And In The Form Of Scientific Data Sets, Indicating The Respective Number And Developmental Stages. The Use Of Fish Traps Is At The Discretion Of The Collector And Is Not Mandatory. If Traps Are Used, They Can Be Used In Accordance With The Above If Necessary. Remain In The Water For A Shorter Period Of Time (E.G. From 3:00 P.M. To 10:00 P.M. Or Similar). During The Inspections, The Study Waters Should Also Be Searched For Evidence Of The Presence Of Inv
