Information about funding sources that supported the collection of the data: Funding was received from a National Geographic Early Career Grant (EC-336R-18) awarded to JKvB, the University of British Columbia’s Faculty of Forestry (no grant number), and the Natural Sciences and Engineering Research Council of Canada (NSERC), through a Canada Graduate Scholarship to JKvB (no grant number) and NSERC Discovery Grant (DGECR-2018-00413) to ACB. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.


SHARING/ACCESS INFORMATION

1. Licenses/restrictions placed on the data: 

2. Links to publications that cite or use the data: 

3. Missing spatial information in data: Detection data comes from camera traps placed on private property, to protect the privacy of land owners, locations in this dataset are only referred to by their ID (e.g. Sooke01). To access the camera location data, contact authors.

DATA & FILE OVERVIEW

1. File List: 
	a) Klees van Bommel_2022_Black Bear Detections 30 min; created 2019-09-13, final update 2021-12-15: raw camera data for every black bear detection separated by 30 min.
	b) Klees van Bommel_2022_Model Variables; created 2019-09-27, final update 2021-12-15: calculated relative abundance and environmental and anthropogenic variables (raw and standardized) used to model black bear habitat use by site/month.

2. Relationship between files, if important: file a) used to calcuate relative abundance (RA) in file b)

3. Additional related data collected that was not included in the current data package: camera trap locations not included (see above), file a) also used to calcuate nocturnal vs. diurnal bear detections.


METHODOLOGICAL INFORMATION

1. Description of methods used for collection/generation of data: See full methods on Dryad

2. Methods for processing the data: camera trap detection data IDed using Timelapse Image Analyzer 2.0. See paper for full methods.
