Trade‐off between height growth and stem diameter growth for an evergreen Oak, Quercus glauca, in a mixed hardwood forest

1997

Summary 1.Patterns of stem growth of a mid-successional evergreen Oak species (Quercus glauca) in a mixed hardwood forest were examined to explore the trade-off relationship between stem-diameter growth and height growth. 2. The mean cross-sectional area (and the corresponding mean diameter) of a stem at a point in time was defined as the stem volume divided by tree height. Based on this definition, a simple equation representing the trade-off relationship between the height growth and mean diameter growth was formulated. 3. In the long term, allocation to height growth was encouraged at the seedling stage and it gradually declined with time, with the decline in the suppressed seedlings being more pronounced than in the dominant trees. 4. However, both the suppressed and the dominant trees showed acceleration of height growth at various ages. Such a fluctuation in the allocation of biomass to height growth is likely to have been caused by chronological changes in light conditions, and meandered the trajectory of allometry between the height and mean diameter. 5. The observed stem growth patterns of the individual trees could explain the chronological changes in the diameter-height relationship of the population.

“…On Iriomote Island, the Adinandra yaeyamensisCastanopsietum sieboldii Miyawaki community generally develops where tertiary sandstone and shale occur (Miyawaki, 1989). In general, the community is dominated by C. sieboldii (mega-phanerophyte), which comprises the highest layer with a mean tree height of 8∼12 m, accompanied by other mega-or meso-phanerophyte species.…”

“…Komidake at 469 m above sea level (a. s. l.) Elevations at the study site range from 60 m to 100 m a. s. l. The study site is covered by well-developed EBLF forest. The bedrock is composed of sandstone, from which a yellow soil develops (Miyawaki, 1989). Soil samples were collected at each study plot, and further physical and chemical analyses revealed that there were no significant differences between the soils of burned and unburned plots prior to clearcutting .…”

-• To elucidate the application of natural regeneration to the restocking of evergreen broad-leaved forests in the subtropics, the characteristics of a 20-year-old evergreen broad-leaved forest restocked by natural regeneration after clearcut-burning were studied in Okinawa, Japan. Within a 0.87 ha clearcut area with four 10 m × 10 m sampling plots, two burned and two unburned ones, the tree composition, tree species diversity and vegetation changes were investigated.• The results showed that the species diversity, basal area and density of woody stems 1.0 m in height differed significantly among phanerophyte types, while they were not significantly different between the burned and unburned treatments. A vegetation census also revealed no obvious differences between the treatments.• The primary dominant species, Castanopsis sieboldii, continued to dominate the secondary forest with a broad height distribution.• The structural complexity and high tree species diversity of the regenerating forest after clearcut-burning provides no evidence of degeneration. We can predict that the regeneration forest may gradually develop into stands similar to pre-clearcut primary forest, and that natural regeneration may restore the high tree species diversity of the evergreen broad-leaved forests in Okinawa.forest structure / species diversity / natural regeneration / subtropical evergreen broad-leaved forest / clearcut-burning Résumé -Caractéristiques d'une forêt feuillue sempervirente âgée de 20 ans, reconstituée par régénération naturelle après coupe rase et feu.• Pour élucider la pertinence de la régénération naturelle pour la reconstitution des forêts feuillues dans la zone subtropicale, les caractéristiques d'une forêt feuillue sempervirente, âgée de 20 ans, reconstituée par régénération naturelle après coupe rase et feu, ont été étudiées à Okinawa au Japon. Dans une coupe rase de 0,87 ha, 4 placeaux échantillons de 10 m × 10 m ont été établis : deux après coupe rase et feu et deux après coupe rase. On a étudié la composition des arbres, la structure de la forêt, la diversité spécifique des arbres et les changements de végétation.• Les résultats montrent que la diversité spécifique, la surface terrière et la densité des troncs ligneux d'une hauteur supérieure ou égale à 1,0 m différent significativement parmi les phanérophytes, tandis qu'il n'y a pas eu de différences significatives entre les traitements brûlés et les non brûlés. Le recensement de la végétation a aussi révélé qu'il n'y avait pas de différence évidente entre les traitements.• La principale espèce dominante Castanopsis sieboldii a continué à dominer la forêt secondaire avec une large distribution des hauteurs.• La complexité structurelle et la grande diversité des espèces d'arbre de la forêt régénérée après coupe rase et feu fournissent la preuve qu'il n'y a pas eu dégénérescence. Nous pouvons prédire que ces forêts peuvent se développer graduellement en peuplements similaires à la forêt primaire existant avant la coupe et que la régénération nature...
