Abstract

The combination of climate change and anthropogenic disturbance can cause major changes in forest bird assemblages. Assessing the cumulative effects of forest management and climate change on biodiversity and ecosystem services, such as carbon sequestration and storage and provisioning of wood products is key to informing forest management and conservation decision-making. Specifically, we projected changes in forest composition and structure according to various forest management strategies under a changing climate using LANDIS-II for two case study areas of Quebec (Canada): a hemiboreal (Hereford Forest) and a boreal (Montmorency Forest) area. Then, we assessed projected bird assemblage changes, as well as sensitive and at-risk species. As part of an integrated assessment, we evaluated the best possible management measures aimed at preserving avian diversity and compared them with optimal options for mitigation of carbon emissions to the atmosphere. Forest management and climate change were projected to lead to significant changes in bird assemblages in both types of forest through changes in forest composition. We projected an increase in deciduous vegetation which favored species associated with mixed and deciduous stands to the detriment of species associated with older, coniferous forests. Changes were more pronounced in Hereford Forest than Montmorency Forest. In addition, Hereford’s bird assemblages were mainly affected by climate change, while those in Montmorency Forest were more impacted by forest management. We estimated that 25% of Hereford and 6% of Montmorency species will be sensitive to climate change, with projected abundance changes (positive or negative) exceeding 25%. According to the simulations, a decrease in the level of forest harvesting could benefit bird conservation and contribute to the reduction of carbon emissions in the boreal forest area. Conversely, the hemiboreal forest area requires trade-offs, as mitigation of carbon emissions is favored by more intensive forest management that stimulates the growth and carbon sequestration of otherwise stagnant stands.

This repository includes all files necessary to run the LANDIS simulations, including the executables.

Datasets generated and analyzed within the study area located in two case study areas of Quebec (Canada): a hemiboreal (Hereford Forest) and a boreal (Montmorency Forest) area. We projected changes in forest composition and structure according to various forest management strategies under a changing climate using LANDIS-II. Then, we assessed projected bird assemblage changes.

This dataset also includes all necessary files to run the LANDIS simulations leading to the results presented in the paper. This includes the initialization files as well as the executables.

Description of the data and file structure

Data Tables

"BirdDensity_Hereford.csv"; and "BirdDensity_Montmorency.csv" were used to projected bird assemblage changes for each species ("BirdSpecies") and assemblage ("AgeCover") : forest wetland, forest generalist, and depending on forest cover : Mixedwood, Deciduous and Coniferous and the age of forest stands : Young, Closed, and Mature. The predicted density values from BRT models are presented in this file and were used to estimate the relative abundance of each bird species ("meanDensity") as mentioned in the manuscript. Scenario, Year, replicate, and HarvestTreatment list the different levels of the simulation scenarios presented in the study. "BirdSpecies" codes are detailed in the appendix for each species.

"LandCover_Characteristics_Hereford.csv" and "LandCover_Characteristics_Montmorency.csv" correspond to the percentage of aboveground biomass (Value) of tree species (Veg_name) as a function of the different scenarios simulated (Scenario, HarvestTreatment, Year). The column "Veg_code" correspond to the codes used in the figures in the manuscript.

"OmegaSquare_Hereford.csv" and "OmegaSquare_Montmorency.csv" correspond to the relative importance of each driver of change ("Climate" and "Harvest") assessed by estimating the variance of bird abundance explained using omega-squared values (ω^2). Omega-squared values was determined for each "Species" of birds and each climate "Scenario" and "Year", as explained in the manuscript.

"Table 3.csv" correspond to the S3 Table in the Supporting information : Relative importance of vegetation and topography predictors in each bird species BRT model.

"Species" corresponded to bird species. All the other columns are presented in S2 Table in the Supporting information, and here :
