Title
EPIPHYTIC LICHENS IN NORWEGIAN COASTAL SPRUCE FOREST: HISTORIC LOGGING AND PRESENT FOREST STRUCTURE
Jørund Rolstad; Ivar Gjerde; Ken Olaf Storaunet; et al. Ecological Applications 2001. doi:10.1890/1051-0761(2001)011[0421:elincs]2.0.co;2
Other claims from this paper (11)
- Association Epiphytic lichens were associated with brook ravines, especially F. ahlneri and P. crocata.
- Association Lichens were ten times more abundant in ravine bottoms than slopes and plateaus.
- Observation All studied lichen species used spruce as their main substrate.
- Observation L. pulmonaria, L. scrobiculata and Nephroma spp. preferred scattered deciduous trees.
- Association Ramalina thrausta occurred more often on older trees and increased with stand age.
- Association S. globosus occurred more often on older trees and increased with stand age.
- Association Lichen numbers tended to rise with tree density in ravine bottoms.
- Association Lichen numbers tended to decline with tree density on slopes and plateaus.
- Observation All surveyed locations had been selectively cut at least twice in 100 years.
- Association Logging history variables did not explain a significant share of current lichen abundance after accounting for stand structure.
- Recommendation The authors suggest moderate selective cutting as an option for sustaining viable lichen assemblages.
