In 2024, De Volkskrant, Landschappen NL, and Vroege Vogels teamed up to launch a brand new award for the best book on nature in the Dutch language: De Natuurboekenprijs (Best Nature Book Award).
The past two years (2025 and 2026) Deleo was commissioned to create an original artwork to be awarded to the winner along with a cash prize.

Past year winners were Eva Meijer with “Muizenleven” (2025) and Tine Hens with “Archief van mogelijk verlies” (2026)
