1. Resolution 147 (Vienna-2) WG 2 welcomes the proposal for future standardisation activities and collaboration between CEN, DG Environment and ECOSTAT and gratefully thanks Dr Cardoso for her contribution to this process. Resolution 149 (Vienna-4) WG 2 is pleased to note that Dr Sweeting will meet with representatives of DG Environment on 21st June 2007 and looks forward to his report of the meeting, which will be provided within 2 weeks. Resolutions from WG2 in Vienna

2. Resolution 155 (Vienna-10) The following work items, developing standards and standards are recommended for inclusion in the draft mandate for the European Commission: Task group 1: Water Quality – Guidance on field and laboratory procedures for quantitative analysis and identification of macro-invertebrates from inland surface waters Task group 3: prEN 15460 “Water quality — Guidance standard for the surveying of macrophytes in lakes” NWIP “Water quality – Phytoplankton biovolume determination by microscopic measurement of cell dimensions” NWIP “Water Quality ‑ Guidance on quantitative and qualitative sampling of phytoplankton from inland waters” European Macrophyte Reference List.
