Resiliency of Landscapes to Disturbance: the Hydrological and Geomorphological Responses of Two Watersheds in British Columbia to an Extreme Snowmelt Event 14 Years After a Severe Wildfire
Owens, Philip Neil — 2020-06-08 Suspended sediment concentration and river discharge data for Fishtrap and Jamieson watersheds, BC, for the period 2004 to 2017. SSC was obtained using automatic water samplers that were operated and processed by the authors. Q data was obtained from Water Survey of Canada (Environment and Climate Change Canada) websites.

Interactions between Sitka alder and lodgepole pine in the BC central interior
Sanborn, Paul — 2022-07-27 This dataset consists of files containing measurements of lodgepole pine and Sitka alder, pine foliage chemistry, and soil properties collected in 2020 and earlier for a silvicultural experiment conducted jointly by Paul Sanborn (UNBC) and research staff of the BC Ministry of Forests. The study was initiated in 1994 and treatments were implemented in 1995 at a site approximately 60 km southwest of Prince George. The project is identified as Experimental Project (EP) 1185 of the Ministry of Forests, which has a duplicate backup of these data files in its own archiving system. Full descriptions of the treatments and data collection methods are given in the cited publications. The pdf file has descriptions of the individual data files, including identification of variables.

The Canadian Human Footprint
Johnson, Chris; Wheate, Roger; Hirsh-Pearson, Kristen; Schuster, Richard; Venter, Oscar — 2020-02-20 Abstract: Efforts are underway in Canada to set aside terrestrial lands for conservation, thereby protecting them from anthropogenic pressures. Here we produce the first Canadian human footprint map by combining twelve different anthropogenic pressures and identify intact and modified lands and ecosystems across the country. Our results showed strong spatial variation in pressures across the country, with just 18% of Canada experiencing measurable human pressure. However, some ecosystems are experiencing very high pressure, such as the Great Lakes Plains and Prairies national ecological areas which have over 75% and 56% of their areas, respectively, with a high human footprint. In contrast, the Arctic and Northern Mountains have less than 0.02% and 0.2% of their extent under high human footprint. A validation of the final map, using random statistical sampling, resulted in a Cohen Kappa statistic of 0.91, signifying an ‘almost perfect’ agreement between the human footprint and the validation data set. By increasing the number and accuracy of mapped pressures, our map demonstrates much more widespread pressures in Canada than were indicated by previous global mapping efforts, demonstrating the value in specific national data applications. Ecological areas with immense anthropogenic pressure, highlight challenges that may arise when planning for ecologically representative protected areas.
