Common use of Field Data Clause in Contracts

Field Data. A primary goal of the field data collection, was to locate the 130 field plots across the full range of riparian forest types in the Mashel watershed. These plots were then measured for the various riparian forest metrics under investigation and either used to build the models, assess the accuracy of the models or both. The watershed was pre-stratified into bins, and eight to 14 plot locations were randomly chosen for each bin from potential areas of the watershed in that bin, this binning process is described more in-depth in Appendix B. Certain bins made up a higher proportion of the watershed, so these bins were assigned more plots. Thus, very large trees, which are rare on the landscape, had fewer bins and thus fewer plots. There are also fewer of these trees in our models and the residuals associated with these heights of these trees are larger, thus the errors in height estimates for these taller trees will also be slightly greater. This is a common issue with LiDAR data, especially since we don’t expect the LIDAR pulse to hit the or even register a return off the most top leader of the tree. For more detailed information, see Appendix B - Plot Location Selection. The field data collection is described briefly in Appendix C and a full field data collection Protocol is provided as a separate publication (▇▇▇▇▇▇ ▇. ▇., 2016). 1. ▇▇▇▇▇▇, ▇. ▇., ▇. ▇▇▇▇▇ and T.
