bSims: methods and products to support survey design

BAM continues to develop tools and methods to help researchers design better monitoring programs.

BAM team member Péter Sólymos created the bSims R package to help researchers design better monitoring programs. The bSims package is a bird point count simulator, which was first presented as a teaching tool at a workshop at the American Ornithological Society 2019 Meeting in Anchorage, AK. The package has since evolved into a standalone tool that (1) allows for easy testing of statistical assumptions and exploring the effects of violating these assumptions and (2) aids survey design by comparing different options. The package presents a spatially explicit mechanistic simulation framework that is based on statistical models widely used in the analyses of bird point count data (i.e., removal models, distance sampling). The workflow involves (1) interactive exploration of multiple setups, e.g., comparing roadside vs. off-road sampling; (2) the settings can be copied from the web application and used in the command line tool to conduct more extensive simulations. 

The bSims package implements the following main functions for simulation: (1) initialize and (2) populate the landscape, (3) animate (individual behaviours described by movement and vocalization events), (4) detect (the physical aspect of the signal transmission), and (5) transcribe (the counts by distance and time intervals).

New Publication: Prioritizing Areas for Land Conservation and Forest Management Planning for the Threatened Canada Warbler in the Atlantic Northern Forest

In February 2020, we published our work identifying priority regions for Canada Warbler conservation and forest management in BCR 14. We developed seven conservation planning scenarios to prioritize candidate areas for permanent land conservation or responsible forest management. We found that using low natal dispersal distance scenarios in decision-making offers a more conservative approach to maintaining Canada Warbler populations. This prioritization approach provides a toolkit for managers to immediately locate areas for implementing conservation and management actions. This work was published in Diversity and was a collaborative effort with Environment & Climate Change Canada (ECCC), and High Branch Conservation Services, with support from Nature Canada and the Canada Warbler International Conservation Initiative.
