Six emergent narratives the graph braids together. None are about a single species — each is about what the data does when you look across decades, lifespans, and arrival dates:
Highlights:
- The otter that came home — first Bos record 1930, last 20th-century record 1952, then 74 years of silence, then returned on 2026-03-31 and 2026-05-07. See Lutra lutra.
- The trees will outlive the design — Taxus baccata can live 3,000 years; the Bosplan 2020–2030 expires in four. See Taxus baccata.
- The forest is only now learning to decompose — the first Trametes versicolor record is from 2008; Fomes fomentarius from 2015. The saprotrophic guild arrived on the schedule the dead wood demanded. See Trametes versicolor.
- The most-cited rarity is not in the database — Cortinarius variiformis was declared a NL-first record here in 2019, yet has zero observations in waarneming.nl. See Cortinarius variiformis.
- The kingfisher's crash and resurrection — 9 breeding pairs in 2020, 1 after the February 2021 frost, full recovery by 2024. See Alcedo atthis.
