Other claims from this paper (16)
- Observation Adventitious roots occurred in over 50% of stems in every stand and 90% in six stands.
- Observation Strong adventitious root systems occurred on more than 30% of stems in seven stands.
- Association Prostrate stems were consistently associated with layering.
- Association Deeper humus-rich or peaty soil horizons were consistently associated with layering.
- Association Layering was associated with absent or scarce Hypnum cupressiforme/jutlandicum and lichens.
- Association Layering was associated with absent or scarce lichens, mainly Cladonia spp.
- Association There was weak evidence of more layering with Sphagnum spp. presence.
- Association There was weak evidence of more layering with Leucobryum glaucum presence.
- Association There was weak evidence of more layering with pleurocarpous mosses other than Hypnum.
- Association Younger stands had more layering.
- Association Strongly layered stands were more sheltered.
- Association Strong layering was associated with greater stem and canopy vigour beyond the rooting point.
- Association Strong layering was sometimes associated with atrophy of the remaining stem.
- Mechanism The authors infer that layering may fill canopy gaps and reduce conditions suitable for later layering.
- Observation The authors consider layering underappreciated in previous Calluna studies focused on regularly burned stands.
- Recommendation The authors question regular burning on 10-15 year rotations as a management ideal.
