2020 Western Mensurationists Conference: Forestry at the Crossroads: Advancements in Natural and Artificial Intelligence

Online; 15-16 June 2020
Details: https://mensurationist.net/2020-western-mensurationists-conference/       

The advancements in computer sciences and material sciences that occurred in the last two decades changed the way how forest measurements and forest modeling is perceived and approached. To this end, not only methods that are computational intensive are now dominating the modeling world, but also the measurements world, as wall-to wall information is available. Therefore, the overarching aim of the 2020 Western Mensurationists conference gravitates around forestry measurements, modeling, inventory, growth and yield and planning, with emphasis on artificial intelligence. Nevertheless, advances in methods and procedures that are rooted in traditional forest measurements and modeling, now falling under the natural intelligence umbrella, are still a significant part of forestry. Therefore, presentations showcasing biometrics, understood in a very broad sense, in the era of big data and remote sensing are encouraged. The abstract submission deadline is Friday, 1 May 2020!

Special issue of Forest Science

Forest Science agreed to dedicate a special issue to the event theme: Forestry Advancements in the Natural and Artificial Intelligence Era. You do not need to be a presenter at the conference to submit a manuscript for the special issue. For those wishing to present, please indicate in your abstract submission if you wish to submit a manuscript to a special issue in Forest Science. Manuscripts will be due by August 31st, 2020 on the journal website: https://academic.oup.com/forestscience.

About Unit

Technological developments in data acquisition have shifted the focus in forest modelling from sampling-based approaches to population-based methods. In these new settings, the equation-based models are supplemented with statistical learning techniques. Irrespective of the modelling approach, the computational aspects of the modelling process adds a new dimension to the complex relationships to be represented with equations or algorithms. These data offer new challenges to modelling spatially explicit ecological processes not well addressed in the broader statistical learning community.

The objective of the 4.03.02 unit is to foster conversation among scientists interested in complex modelling using advanced statistical and computational methods and to provide a platform for researchers and practitioners of forest modelling.


State of Knowledge

The transition from sample to population models is accompanied by an increase in the number of tools used to answer forest research questions. The traditional equation-based models that relate a set of predictors to a dependent variable, whose epitome are the taper and site index equations, is now accompanied by a plethora of machine learning and heuristic techniques. Furthermore, the approaches focused on one aspect of forest have given way to holistic approaches aimed at understanding ecosystem-level pattern-process linkages. Therefore, hierarchical or simultaneous models are now defining the representation of forest dynamics. Furthermore, stand-level approaches are now either integrated within higher-order landscape models or broken down into smaller modelling units, such as individual trees to inform process-based landscape simulation models. 

In the current social and scientific settings, the hot topics addressed by the 4.03.02 unit are:

  1. Development of parsimonious multiscale models
  2. Spatially explicit models of the development of tree components as a part of the forest ecosystem
  3. Integration of remote sensing data into landscape modelling
  4. Machine learning modelling for the exploration and prediction of landscape disturbance patterns
  5. Spatial decision support tools to integrate model predictions into transparent and quantitative management decision making.
  6. Application of landscape simulation models to facilitate hypothesis testing of small-scale ecological processes
