Macroecology of Australian Tall Eucalypt Forests: Baseline Data from a Continental-Scale Permanent Plot Network
Tracking the response of forest ecosystems to climate change demands large (≥1 ha) monitoring plots that are repeatedly measured over long time frames and arranged across macro-ecological gradients. Continental scale networks of permanent forest plots have identified links between climate and carbon fluxes by monitoring trends in tree growth, mortality and recruitment. The relationship between ...
متن کاملAssessing the quality of permanent sample plot databases for growth modelling in forest plantations
Informed plantation management requires a good database, since the quality of information depends on the quality of data, growth models and other planning tools. There are several important questions concerning permanent plots: how many plots, where to put them, and how to manage them. Plot measurement procedures are also important. This paper illustrates graphical procedures to evaluate existi...
متن کاملOutliers and/or measurement errors on the permanent sample plot data
Estonian Agricultural University, Institute of Forestry and Rural Engineering, Kreutzwaldi 5, 51014 Tartu, Estonia. Email: [email protected] __________________________________________________________________________________ Abstract Tree-wise re-measured permanent sample plot data are needed to create and maintain modern forest growth models for Estonia.

متن کاملEvaluation of a Smartphone App for Forest Sample Plot Measurements
We evaluated a smartphone app (TRESTIMATM) for forest sample plot measurements. The app interprets imagery collected from the sample plots using the camera in the smartphone and then estimates forest inventory attributes, including species-specific basal areas (G) as well as the diameter (DgM) and height (HgM) of basal area median trees. The estimates from the smartphone app were compared to fo...
متن کاملGetting the most out of your permanent plot data
A catalogue of ideas for graphical analyses of growth data is presented, in the hope of stimulating the more imaginative analyses. Graphs can be particularly revealing, because the human eye is good at detecting patterns. Suggestions are given to make graphs more effective, and analyses more insightful.
