Anna Khokh Forestry Engineering Journal 2024. doi:10.34220/issn.2222-7962/2023.4/24

Other claims from this paper (12)

Observation Ledum pine forests had 3.34 times as many anomalies as mossy pine forests.
Observation Mossy pine forests had 229 density fluctuations.
Observation Ledum pine forests had 530 density fluctuations.
Observation Frost damage counts were 28 in mossy pine and 159 in ledum.
Observation Fallen tree rings numbered 10 in mossy pine and 202 in ledum.
Observation The most unfavorable radial growth years for mossy pine were 1979 and 1980.
Observation The most unfavorable radial growth years for ledum pine were 1906 and 1940.
Observation Mossy pine anomaly maxima occurred in eleven listed years and accounted for 91,4%.
Observation Ledum pine anomaly maxima occurred in thirteen listed years and accounted for 89.7%.
Observation The timing of anomalies and growth minima did not coincide between the two pine forest types.
Association Annual ring structure reflects seasonal growth of common pine.
Mechanism Soil hydrology largely determines pine ring structural anomalies.
