A cover meter for canopy and basal cover estimations

open access: yesBothalia: African Biodiversity & Conservation, 1984
A simple, inexpensive, pocket-sized cover meter for estimating both canopy and basal cover is described. The cover meter is based on the visual superimposition of canopy-to-gap ratio scales, on to vegetation.

ICESat-2 for Canopy Cover Estimation at Large-Scale on a Cloud-Based Platform [PDF]

open access: yesSensors, 2023
Forest canopy cover is an essential biophysical parameter of ecological significance, especially for characterizing woodlands and forests. This research focused on using data from the ICESat-2/ATLAS spaceborne lidar sensor, a photon-counting altimetry ...

A spatially comprehensive canopy cover dataset derived from NASA’s ice, cloud and land elevation satellite-2 (ICESat-2) for the state of Alabama, USAThe Open Science Framework [PDF]

open access: yesData in Brief
NASA’s Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) has already demonstrated an extraordinary capability to assess forests, including providing measurements of canopy heights, and estimating aboveground biomass (AGB) and canopy cover.

Changes in conservation value from grasslands to savannas to forests: How a temperate canopy cover gradient affects butterfly community composition. [PDF]

open access: yesPLoS ONE, 2020
Temperate savannas and grasslands are globally threatened. In the Midwest United States of America (USA), for example, oak savannas persist today at a small percentage of recent historic coverage.

A note on estimating canopy cover from digital cover and hemispherical photography [PDF]

open access: yesSilva Fennica, 2016
Fast and accurate estimates of canopy cover are central for a wide range of forestry studies. As direct measurements are impractical, indirect optical methods have often been used in forestry to estimate canopy cover. In this paper the accuracy of canopy

Estimating canopy cover in Scots pine stands [PDF]

open access: yesSilva Fennica, 2005
The way canopy cover is defined and measured influences the obtained canopy cover percentage. Estimates of canopy cover are needed, for example, in canopy radiation modelling and remote sensing applications and as a tool for political decision-making.

THE CONNECTION BETWEEN CANOPY COVER AND WATER QUALITY IN THE COASTAL OF TABANIO VILLAGE OF TANAH LAUT REGENCY, SOUTH KALIMANTAN [PDF]

open access: yesRussian Journal of Agricultural and Socio-Economic Sciences, 2023
Canopy cover is one approach to measuring canopy density. The area of land is covered by the vertical projection of the plant canopy or tree canopy is known as canopy cover.

Estimation of canopy attributes of wild cacao trees using digital cover photography and machine learning algorithms

open access: yesiForest - Biogeosciences and Forestry, 2021
Surveying canopy attributes while conducting fieldwork in the rain forest is time-consuming. Low-cost imagery such as digital cover photography is a potential source of information to speed up the process of vegetation assessments and reduce costs during
