Other claims from this paper (15)
- Observation Plantation age structure stayed uniform for 50–55 years.
- Observation The critical age was 55 years under the region’s high anthropogenic and climatic loads.
- Association Plantation condition and morphometric indices correlated with urban anthropogenic load.
- Observation Control plants were weakened slightly, scoring 2 points.
- Intervention effect Under increased anthropogenic load, plants were severely weakened, scoring 3 points.
- Observation A quarter of sampled plants were in critical condition.
- Observation Crowns and trunks displayed core rot, mechanical damage, crown thinning, and drying.
- Association Early crown area deviation did not depend on growth location.
- Observation Pruned roadside crown area averaged no more than 22–23 m2.
- Observation The associated allometric coefficient was 0.35–0.37.
- Observation Crown area under high load was 36 ± 11% lower than in controls.
- Observation At highly polluted sites, mcr decreased 71% versus control.
- Observation At highly polluted sites, EI decreased 75% versus control.
- Observation At highly polluted sites, RRB decreased 43% versus control.
- Recommendation Authors recommend retaining P. bolleana as a main urban dendrobanocenosis species.
