Day 2 was about measuring the soil condition after a forest fire. Day 3 was all about peat action by measuring the water level and methane emission. The final day was about uprooting the Himalayan Balsam, an invasive plant species, from an old-growth forest in Selkie, Eastern Finland.

In this episode, Letty had the opportunity to chat with Alicia Jarma, a biodiversity specialist from Spain, about old-growth forests, greenhouse gas emission, and invasive plant species.

Her key message is in Catalan, Spanish, French, and English.
