Tender: Horizon Scanning and Pathways Analysis for Invasive Non‑Native Species in Scotland’s Islands, River Catchments and Marine Regions

About

A Scottish commissioning body is seeking a supplier for horizon scanning and pathways analysis of invasive non‑native plants and animals across Scotland’s islands, river catchments and marine regions. Work Package 1 requires assessment of terrestrial, freshwater and marine non‑native species with potentially negative impacts on biodiversity and ecosystem services that are likely to be introduced to these regions within the next ten years. Work Package 2 requires compilation of potential introduction pathways for both established invasive non‑native species in Scotland and species identified through the horizon scanning exercise, applying the pathway terminology and assessment methodology used in the previous Scottish pathways analysis (Roy & Carvalho, 2023); pathways may operate within Scotland and from further afield.
