Street treeTree allometryUrban forestForesters use diameter at breast height (DBH) to estimate timber volumes, quantify ecosystem services, and predict other biometrics that would be difficult to directly measure. But DBH has numerous problems, including a range of "breast heights" and challenges ...
an auditor must obtain reasonable assurance as to whether the financial statements as a whole are free from material misstatement, whether due to fraud or error. Reasonable assurance is a high, but not absolute, level of assurance. The auditor has to identify and...
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 ...
Tree hollows are an important habitat resource used by arboreal fauna for nesting and denning. Hollows form when trees mature and are exposed to decay and physical damage. In the absence of excavating fauna, hollow formation can take up to 200 years in Australian temperateEucalyptusforests, making...
National forest inventory (NFI) data provides massive amounts of ground-based measurements on forest growth, including stock volume, diameter at breast height (DBH), tree height, average age, depression and dominant tree species (Tang et al., 2018). NFI data have been used to estimate forest...
Let’s map this in CARTO Builder, but limit the query to only select geometry, tree_id and dbh (Diameter at Breast Height) fields. To do this, open a new map (Maps > Create Map) and under sources, select Add a source from > Custom query. Copy the below query to load this data...
Here * stands for a variable six-digit number. Some of these files may be absent. Move any that you have to the Trash and close the Finder window. Log out or restart the computer. The trojan will now be inactive, but there are a few more components of it that should be cleaned up...
First, let’s start by writing out what it is we actually want to model. We want to know how DBH varies as a function of tree height, but we can also write that out as: DBH_in ~ height_ft, the tilde (~) being read as “is a function of.” ...

However, as these interventions have only raised deadwood levels in production forests to an average of 8 m3 ha− 1 (> 10 cm dbh; Kruys et al., 2013), and require only a limited number of living trees be retained per hectare at final felling, some question their adequacy relative to ...
