The umbrella value of caribou management strategies for biodiversity conservation in boreal forests under global change

Single-species conservation management is often proposed to preserve biodiversity in human-disturbed landscapes. How global change will impact the umbrella value of single-species management strategies remains an open question of critical conservation importance. We assessed the effectiveness of threatened boreal caribou as an umbrella for bird and beetle conservation under global change. We combined mechanistic, spatially explicit models of forest dynamics and predator-prey interactions to forecast the impact of management strategies on the survival of boreal caribou in boreal forest. We then used predictive models of species occupancy to characterize concurrent impacts on bird and beetle diversity. Landscapes were simulated based on three scenarios of climate change and four of forest management. We found that strategies that best mitigate human impact on boreal caribou were an effective umbrella for maintaining bird and beetle assemblages. While we detected a stronger effect of land-..., All the methods are detailed in the article: Labadie G. et al.

Datasets generated and analyzed within the study area located in the Côte-Nord region of Québec, Canada. To identify species-specific movement rules that were implemented in the IBM, we used empirical data collected for caribou, moose, and wolves over the study area. To evaluate the umbrella value of management strategies for caribou habitat conservation, we used predictive models of species occupancy to characterize concurrent impacts on bird and beetle diversity.

## Description of the data and file structure

\"Beetles\_ProbaOcc.xlsx\"; \"Birds\_ProbaOcc\_DecMixte.xlsx\" and \"Birds\_ProbaOcc\_Mature.xlsx\" were used to determine the Jaccard dissimilarity index for each group: beetles, birds associated with boreal mixed forests and birds associated with boreal coniferous forests. The probability of occurrence presented in these files was based on predictive models of o...
