SFI Conservation Value Assessment Tool

SFI Conservation Value Assessment Tool


BAM's data and models have been used to develop a web-application tool to support conservation planning and to explore the conservation value of certified forests.

BAM’s representation analysis and associated web-application, created in partnership with the Boreal Ecosystems Analysis for Conservation Networks Project (BEACONs), are contributing to the Sustainable Forestry Initiative’s (SFI) understanding of the value of sustainable forest management for conserving avian biodiversity.

The BAM and BEACONs SFI Representation Assessment Tool is an online application that enables users to explore and evaluate the representation of bird-related conservation values within SFI-certified forestlands at multiple spatial scales ranging from ecoregions to the entire Canadian boreal region. The current focus is on the evaluation of a suite of species and biophysical indicators that were selected by BAM and BEACONs. We measured conservation value by evaluating the ecological representation of the indicators i.e., how well do SFI lands represent each indicator?

This initiative benefitted from The SFI Conservation Grant program.

NA-POPS: Point Count Offsets for Population Sizes of North America Landbirds

© Benoît Audet

BAM is a primary partner on a new project to generate open-source detectability offsets for all North American landbirds. These offsets will allow for the quantitative integration of observations from different programs and field protocols. 

This project is a collaborative effort with the Canadian Wildlife Service (CWS), Boreal Avian Modeling Project (BAM), Canadian Forest Service (CFS), Partners in Flight Science Committee (PIF), and more. 

New Canada-wide land bird density estimates (version 4.0)

New Canada-wide land bird density estimates (version 4.0)


Population sizes, habitat associations, and distributions for 143 landbird species to support status assessment, regional planning, conservation prioritization, and recovery of species at risk.

Density map of Canada Warbler (average density, males/ha)


In 2020, BAM launched version 4.0 of our Canada-wide density models for 143 species of landbirds. 

The development of national-scale products is challenged by sparse data in remote regions, complex species' responses to environmental factors, regional variation in habitat selection and more. However, reliable information on species’ population sizes, trends, habitat associations, and distributions is important for conservation planning and management.

To support avian conservation in Canada, BAM developed a generalized analytical approach to model species densities in relation to environmental covariates. We used the BAM database and built models for 143 species.  Learn more about these methods and models.


We provide data and maps of population sizes, habitat associations, and distributions for 143 landbird species. We provide our density results as 1 km² resolution raster layers, which are used to calculate population sizes and regional habitat associations.

Le français suit

We are pleased to provide you with the 2019-20 BAM Annual Report, outlining BAM’s activities and collaborations during our previous year. We apologize for the late release of this report resulting from unusual circumstances related to COVID-19. As you will see in this report, our partnerships, dedicated team, and incredible staff make it possible for us to achieve the many accomplishments reported here. 

Among these accomplishments, you can read about:

  • New Canada-wide landbird density estimates for 143 species (national density maps & population size estimates);

  • New Canada-wide density models for 18 species of waterfowl that explicitly account for spatio-temporal variations in abundance;

  • Continued efforts to develop a Standard Operating Procedure to identify critical habitat for wide-ranging species at risk;

  • Numerous regional studies simulating the impacts of changes in climate, forest harvest, fire, caribou conservation, and energy-sector development on boreal bird populations;

  • Conservation planning scenarios to prioritize candidate areas for Canada Warbler conservation;

  • Efforts towards improved open access to avian data in Canada;

  • Applications of our work through collaborations with over 30 different partners.

New Publication: Response of birds to the effects of caribou conservation, harvest, fire, and energy-sector impacts

New Publication: Quantifying long-term bird population to responds to the effects of caribou (Rangifer tarandus) conservation, harvest, fire, and energy-sector development in Alberta.

As interest in caribou conservation continues to increase, there is growing interest in understanding potential trade-offs or co-benefits with other species. This new paper, led by Lionel Leston investigated how boreal birds will respond to the cumulative effects of caribou conservation, harvest, fire, and energy-sector development in Alberta. The results demonstrate that caribou-centric forestry plans have minor co-benefits for avian species in Alberta. Read more...

Webinar: Managed Forests for Birds in the Boreal Transition Region of the US and Canada

On June 3, 2020, the Boreal Avian Modelling Project in partnership with the SFI Conservation Team and the American Bird Conservancy (ABC) delivered an e-workshop on Managed Forests for Birds in the Boreal Transition Region of the US and Canada. The goal of the workshop was to engage forest management organizations and other interested parties in the Boreal Transition Zone of the Lake States and Ontario in the role of active forest management in bird conservation.

The objectives of this e-workshop were to:

  • Better understand the forest management practices, objectives, ownership patterns and other landscape factors in the study area;
  • Identify opportunities for forest management decisions to significantly influence bird habitat conditions;
  • Identify potential tools, products, training, and outreach materials to help inform forest management decisions;
  • Propose a collaborative framework for gaining and sharing scientifically-based knowledge about forest management effects on birds; and
  • Form a working group from forestry and conservation to address opportunities for birds of conservation concern.

BAM team member Andy Crosby is part of the team leading this co-produced research project. If you have management responsibility in the U.S. northern Lake States or northwest Ontario, Canada (Bird Conservation Region 12), this research project may be of particular interest to you. If you have avian point count data from this region, we would appreciate data contributions to support this work. Please contact us if you are interested in learning more about this project.

Prioritizing Areas for the Threatened Canada Warbler in Atlantic Canada

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.
