Pre- and post-windstorm leaf area index of Carpinus betulus trees in an urban forest patch

Publikováno v: İstanbul Üniversitesi Orman Fakültesi Dergisi, Vol 66, Iss 2, Pp 513-523 (2016)

Natural disturbances are rather rare for the urban forests compared to the anthropogenic ones. However, forcible natural impact may be substantially destructive such as severe storms. Instantaneous defoliation is one of the significant signatures of

Influence of Fire on the Natural Regeneration of a Semideciduous Seasonal Rainforest Fragment

Autor: Bruna Paolinelli Reis, Katucia Sandra Zatelli, Fillipe Tamiozzo Pereira Torres, Sebastião Venâcio Martins

Publikováno v: Floresta e Ambiente, Vol 25, Iss 4 (2018)

ABSTRACT The objective was to evaluate the influence of fire in a forest fragment through litter biomass analysis, regeneration of Cecropia sp., and canopy openness. Two treatments were established, one of them corresponding to an area affected by fi

Comparison of optical and digital techniques for light microclimate assessment in the Paneveggio Forest, Trentino, Italy

Publikováno v: Forest@, Vol 3, Iss 2, Pp 191-204 (2006)

Hemispherical photography is a widely used tool for the indirect estimation of forest light environment and quantification of canopy openness, LAI, and direct and diffuse canopy light transmittance. Several comparisons have been made in existing lite

Estimating Savanna Clumping Index Using Hemispherical Photographs Integrated with High Resolution Remote Sensing Images

Autor: Jucai Li, Wenjie Fan, Yuan Liu, Gaolong Zhu, Jingjing Peng, Xiru Xu

Publikováno v: Remote Sensing, Vol 9, Iss 1, p 52 (2017)

In contrast to herbaceous canopies and forests, savannas are grassland ecosystems with sparsely distributed individual trees, so the canopy is spatially heterogeneous and open, whereas the woody cover in savannas, e.g., tree cover, adversely affects

Volume 9
Issue 10

The forest canopy is the medium for energy and mass exchange between forest ecosystems and the atmosphere. Remote sensing techniques are more efficient and appropriate for estimating forest canopy cover (CC) than traditional methods, especially at la

Leaf Area Index Derived from Hemispherical Photograph and its Correlation with Aboveground Forest Biomass

Autor: Tyas Mutiara Basuki

Publikováno v: Indonesian Journal of Forestry Research, Vol 2, Iss 1, Pp 31-41 (2015)

Leaf area index (LAI) is one of the key physical factors in the energy exchange between terrestrial ecosystem and atmosphere. It determines the photosynthesis process to produce biomass and plays an important role in performing forest stand reflectan
