Other claims from this paper (19)
- Observation The total area of forests with Rh. luteum undergrowth in moist relatively fertile pine site type (C3) in two forestry enterprises is 2,614.4 ha.
- Observation Of this area, 11.8% comprises forest plantations.
- Observation Quercus robur dominates in 53.5 % of the studied stands.
- Observation Betula pendula occupies 28.6 % of the secondary stands.
- Observation Pinus sylvestris occupies 14.4 % of the secondary stands.
- Observation Populus tremula occupies 2.1 % of the secondary stands.
- Observation Alnus glutinosa occupies 1.5 % of the secondary stands.
- Observation The 71–80-year age group forms the largest proportion of the studied forests, 29.2%.
- Observation The 61–70-year age group forms the second largest proportion of the studied forests, 26.8%.
- Observation In stands older than 40 years the forest coenosis reached a fully developed state with a typical floristic composition and coenotic structure.
- Observation Rh. luteum undergrowth had a projective cover of approximately 45% at 41 years.
- Observation Rh. luteum undergrowth projective cover increased to 60–70% at 58 years.
- Observation Rh. luteum undergrowth projective cover increased to 80–90 % at 66 years.
- Observation The species displayed high vitality, even distribution and mass flowering.
- Intervention effect After clear-cutting, Rh. luteum undergrowth regenerates satisfactorily within 40 years.
- Observation By the 60–70-year age group, development of a closed Rh. luteum undergrowth is nearly complete.
- Observation By the 60–70-year age group, the physiognomy of the coenosis closely resembles that of the original maternal stands.
- Observation In 17% of surveyed plots Rh. luteum failed to regenerate.
- Mechanism The failure to regenerate was attributed primarily to excessive stand density and untimely, insufficient thinning in stands under 30 years old.
