How Accurate Can We Expect Routine Location of Plots Under Forest Canopy Using GPS
24/02/2012 1:50:00 p.m.
Recently, we looked at GPS Precision (EPE). A few questions were also raised about plot location and I thought it might also be good to look at how accurate we could expect to locate the survey point inside the forest under a range of conditions and forest canopies.
The dataset used contains 320 survey points... |

Diameter Breast Height – Where Does it Start From, Ground Level Right?
7/02/2012 2:50:00 p.m.
A discussion recently arose on "what should be considered as the starting point for measurement of diameter breast height, that is at what point does the stump height / tree stem start". Seems simple doesn't it; "high side of the tree at ground level" Well this forest type had a... |
GPS Accuracy Estimate (EPE) What is It ?
7/02/2012 1:58:00 p.m.
The use of recreational grade GPS (for example Garmin 60csx or Garmin 62S) is now standard practice for the location of forest inventory plots in New Zealand and Australia. We recently reviewed a few questions regarding the accuracy and precision of these GPS units, with many in the industry not... |
A Move to Variable-Form Tree / Stem Taper Equations
4/02/2012 2:47:00 p.m.
History of Stem / Tree Taper Equation Development
Taper equations can be used to provide predictions of inside bark diameter at any point along the tree stem and stem volume based on widely recorded tree dimensions. Equations that can accurately predict tree diameter at any point of the stem based on... |

Forest Edges: Walkthrough Solution Alternative to the Plot Mirage Method
28/10/2011 5:41:00 p.m.
Existing popular methods such as the "plot mirage method" (Schmid-Haas, 1969) for eliminating bias due to boundary overlap suffer some disadvantages in practical use;
having to establish a duplicate plot outside the forest edge which might not always be possible (water body, cliff, or private land boundaries),
needing to assume... |
