i-Tree is a collection of urban and rural forestry analysis and benefits assessment tools. It was designed and developed by the United States Forest Service to quantify and value ecosystem services provided by trees including pollution removal, carbon sequestration, avoided carbon emissions, avoided stormwater runoff, and more. i-Tree provides baseline data so that the growth of trees can be ...
Canopy research is a relatively new scientific field which was hampered for a long time by lack of means of access to the tree canopies and lack of appropriate means of housing researchers. Climbing gear, tree houses , canopy walkways , cranes , airships and inflatable platforms resting on the treetops have lately overcome these barriers.
In the United States, the forest cover by state and territory is estimated from tree-attributes using the basic statistics reported by the Forest Inventory and Analysis (FIA) program of the Forest Service. [2] Tree volumes and weights are not directly measured in the field, but computed from other variables that can be measured. [3] [4]
Dominant and co-dominant canopy trees form the uneven canopy layer. Canopy trees are able to photosynthesize relatively rapidly with abundant light, so it supports the majority of primary productivity in forests. The canopy layer provides protection from strong winds and storms while also intercepting sunlight and precipitation, leading to a ...
Some light slips between the tree canopy to the ground, which can reveal forgotten structures. The dataset covered an area of Campeche in Southeastern Mexico where Lowland Maya civilizations once ...
The report looked at data and images from 2020 to determine how much of the county is covered by trees, buildings and water. Tree canopy makes up 54.2%. Other vegetation , like shrubs and grass ...
In contrast, canopy soils that form lower in the canopy are more likely to be sheltered from more extreme swings in light exposure and moisture content. Additionally, lower canopy soils also have a greater chance of accumulating organic matter that falls from higher neighboring trees, or from the higher regions of the tree housing the canopy soil.
Canopy conductance, commonly denoted , is a dimensionless quantity characterizing radiation distribution in tree canopy. By definition, it is calculated as a ratio of daily water use to daily mean vapor pressure deficit (VPD). [ 1 ]
