Leaf shape is tied to the evolutionary history of a tree species, and depending on the ecosystem demands, the leaf’s needs to maximize sunlight capture while minimizing heat absorption and water loss. Overall leaf shape is a trait often used to categorize broadleaves in dichotomous keys. ...
Ran into some bumps trying to get concat to work, error 'couldn't understand the expression starting at this point...' I put concat(${dbh_lt25},'<br>') in the calculation column I think I partially figured it out, by using hidden integer columns instead of ...
Using natural regeneration of forests is part of what is called close-to-nature, ecological forestry (Batavia and Nelson 2016; Palik and D’Amato 2017). Closer to nature forestry is based to a greater extent on the natural dynamics of tree stands, which results in an increase in the ...
Legendre and De Caceres (2013) proposed a method which uses the community composition matrix (sites × species) to calculate the total β diversity (BDtotal). This method allows us to assess the extent to the contribution of individual species to BDtotal (SCBD) within a given community (...
(GIS) to calculate SOC densities for each forest type within a region from soil databases and satellite-derived land cover information. Campbellet al. (2008) showed large differences in the outcomes of both approaches and identified the need to use direct measurements of SOC in order to ...

Using the National Tree Benefits Calculator (Figure 16) and the data collected on the trees, calculate the environmental benefit of each tree. Record the results. Figures 6-15. Unknown leaf samples. Figure 16. National Tree Benefit Calculator. ...
I think I partially figured it out, by using hidden integer columns instead of calculate columns. The calculate seemed to be a string instead of number. Reply 0 Kudos by abureaux 03-13-2024 11:59 AM Do you have ${dbh_lt25} as a field within your s...

A process-based model was used to simulate the wood biomass of T. cordata Greenspire and calculate its ecosystem services [33,34]. On the basis of the basic measurements of trees (e.g., DBH (diameter at breast height) and tree height), climate and soil data, this model consists of sev...
