Other claims from this paper (19)
- Observation The species was recorded with at least 670 colonies in the Netherlands in 1979–1991.
- Observation Of the colonies, 89% are in the Kuinderbos.
- Observation The species prefers shadowed ditches and drainage trenches but can grow in various other habitats.
- Observation In the western and southern Netherlands the species grows on canal walls.
- Observation Sites with Gymnocarpium dryopteris belong to different plant communities.
- Association In the Kuinderbos, stands of Picea sitchensis are preferred by the species.
- Association Elsewhere in the Netherlands the species prefers Quercion roboris-petreae (Fago-Quercetum) or Pseudotsuga mensiezii stands.
- Observation The species is accompanied by 14 fern species.
- Observation At the Kuinderbos the species is accompanied by 12 fern species.
- Observation Rhizomes are shallow creeping, at an average of 2.6 cm below the surface (0.5–8 cm).
- Observation The species grows in the ecto-organic layer or just below it.
- Observation At trench sides the species often grows in the mineral layer.
- Observation Most colonies are within the influence of the watertable.
- Observation Dutch colonies are small, and colonies with more than 1000 fronds are rare.
- Observation Colonies with more than 100 fronds are often fertile.
- Observation Less than 20% of the fronds bear sori.
- Observation At the wall habitat small-sized individuals may be fertile as well.
- Mechanism The high density in the Kuinderbos can be attributed to an optimal water supply from a peat subsoil.
- Observation The high density of Picea sitchensis within the Kuinderbos is unprecedented in Europe and makes these stands resemble the natural habitat of Picea sitchensis in North America.
