說明

In March 2023, freshwater pearl mussels was re-located in the Lysaker river. The relocation was carried out as a precautionary measure because the discharge of injection compounds from the tunnel work at Fornebubanen can cause damage/mortality to occurrences of mussel in the area of influence. Fornebubanen is obliged to monitor the mussel population in the river and report annually to the State Administrator on the condition. On behalf of Fornebubanen, NaturRestaurering AS has carried out a survey in June 2023.

計畫名稱 Re-location and survey of freshwater pearl mussel in Lysakerelva

取樣方法

The survey is conducted by personal observations performed by freshwater ecologists. Density of freshwater pearl mussels was recorded per m2 at stations along a transect in the river. Due to depths which in some cases do not make wading possible, the work was carried out by snorkelling, where the density and condition of mussels were recorded within different zones of the river and recorded continuously in maps (Arcgis fieldmaps). A Gopro camera was used for photo documentation.

研究範圍 The survey was conducted along a 500 meter stretch along the Lysaker river
