Mapping, Monitoring and Risk Management - StDeOe.7022 Amphibians, StDeOe.7023 Openland Bird Species, StDeOe.7024 Vegetation, StDeOe.7025 Phengaris

Lot 1 - StDeOe.7022 Amphibians: As part of the Danube expansion project Straubing – Vilshofen, section 1, Straubing – Deggendorf, monitoring and risk management for LBP measures will be carried out. In this context, data on the settlement success of amphibians and the development of the associated LBP measure areas must be collected. The species concerned are the Garlic Toad (Pelobates fuscus) and the Common Tree Frog (Hyla arborea). The contract duration extends from January 2027 – November 2028. As part of this work, the results must be digitally processed, and an explanatory report and photographic documentation must be created. Lot 2 - StDeOe.7023 Openland Bird Species: As part of the Danube expansion project Straubing – Vilshofen, section 1, Straubing – Deggendorf, monitoring and risk management for selected LBP measures will be carried out. In this context, territory mapping of the current population status of the openland bird species Northern Lapwing (Vanellus vanellus) and Eurasian Curlew (Numenius arquata) must be carried out in 2027. The contract duration extends from February to October 2027. As part of this work, the results must be digitally processed, and an explanatory report and photographic documentation must be created. Lot 3 - StDeOe.7024 Vegetation: As part of the planning approval process for the Danube expansion project Straubing – Vilshofen, section 1, Straubing – Deggendorf, monitoring and risk management for selected LBP measures will be carried out. This monitoring is divided into vegetation-related monitoring and measure-related monitoring. In the context of vegetation-related monitoring, biotope and land use types, as well as FFH mapping including assessment for habitat types 91E0*, 91F0, 9170, and 6210, must be carried out. Furthermore, mapping of the species Lindernia procumbens and species of the pond sedge, pond bottom, and dwarf rush communities will take place. Within the scope of measure-related monitoring, vegetation-ecological investigations on shrub growth, tree species composition, and indicator species for disturbance, as well as further site-specific surveys, are to be carried out. In addition, soil science mapping (finger probe) of various LBP measure areas will be performed. The contract duration extends from 2027 to 2028. As part of this work, the results must be digitally processed annually, and an explanatory report and photographic documentation must be created. Lot 4 - StDeOe.7025 Phengaris: As part of the planning approval process for the Danube expansion project Straubing – Vilshofen, section 1, Straubing – Deggendorf, monitoring and risk management for selected LBP measures will be carried out. In this context, data on the current population status of the Dusky Large Blue (Phengaris nausithous) on reference areas and on the development of LBP measure areas must be collected. As part of this work, the results must be digitally processed, and an explanatory report and photographic documentation must be created.
