Spatio-temporal change detection of forest canopy cover density in the Golestan National Park, Iran [PDF]

open access: yesEnvironmental Resources Research, 2021
In this study, spatio-temporal forest canopy cover density changes in the Golestan National Park (Iran) were assessed from 1967 to 2016 using aerial photos and satellite images in a Geographical Information Systems environment.

Strong influence of trees outside forest in regulating microclimate of intensively modified Afromontane landscapes [PDF]

open access: yesBiogeosciences, 2022
Climate change is expected to have detrimental consequences on fragile ecosystems, threatening biodiversity, as well as food security of millions of people. Trees are likely to play a central role in mitigating these impacts. The microclimatic conditions

Assessing forest canopies and understorey illumination: canopy closure, canopy cover and other measures

open access: yesForestry, 1999
The forest canopy is one of the chief determinants of the microhabitat within the forest. It affects plant growth and survival, hence determining the nature of the vegetation, and wildlife habitat. A plethora of different techiques have been devised to measure the canopy.

Influence of Canopy Cover on Surface Temperature

open access: yesRevista Brasileira de Geografia Física, 2020
Trees affect the microclimate, which influences thermal comfort and ecosystem processes. This study investigated the influence of the canopy cover on daily maximum and minimum temperatures. The data are from a collaborative database, and each measurement consists of the minimum and maximum temperatures under the canopy and in an open adjacent area over

Solar Radiation Transfer Through a Subarctic Shrub Canopy [PDF]

open access: yes, 2007
Much of the low Arctic is covered with shrubs that are partially buried by snow in winter and become exposed during melt. This study presents measurements and modeling of shortwave radiation reflection and extinction by a deciduous shrub canopy emerging ...

Impacts of land cover and management change on top-of-canopy and below-canopy temperatures in Southeastern Kenya

open access: yesScience of The Total Environment, 2023
Los impactos de la conversión de la cubierta terrestre se han estudiado bien desde el nivel superior del dosel utilizando observaciones satelitales. Sin embargo, los impactos de calentamiento o enfriamiento de la cobertura terrestre y el cambio de gestión (LCMC) desde el nivel por debajo del dosel siguen siendo menos explorados.

Assessment of the success of canopy cover revegetation of former coal mine lands with Forest Canopy Density (FCD) Model in Kutai Kartanegara, East Kalimantan

open access: yesJournal of Natural Resources and Environmental Management, 2023
Coal mining plays a vital role in Indonesia's economic growth. However, these activities negatively impact the environment. To minimize this, the Indonesian government requires ex-mining land to be reclaimed, with one of the success criteria being ...

An increase in canopy cover leads to masting in Quercus ilex

open access: yesTrees, 2010
Masting is the intermittent and synchronous production of large crops, but its relation to tree growth remains elusive despite the ecological relevance of mast seeding. The production of huge fruit crops has been linked to the accumulation and consumption of resources as nutrients and carbohydrates, but no conclusive assessment has supported this ...
