Overview

• Poland has folded moor and wetland restoration into its multibillion‑euro East Shield program, framing nature as a force multiplier for border defense.
• Finland is preparing pilot projects, with the environment ministry saying the sites are intended to boost CO₂ storage and complicate any armored incursion.
• Planning centers on vulnerable corridors such as the Suwałki Gap between Poland and Lithuania, where reinstated wetlands could hinder movement toward Kaliningrad.
• Backers cite 2022 fighting near Irpin and Moschun in Ukraine, where flooding and mud bogged down Russian vehicles and disrupted supply lines.
• Officials emphasize the measures are proactive peacetime steps, and note that rewetted peatlands store carbon whereas drained peat releases greenhouse gases.
