Description

This report summarizes the results of a reclamation project at Rocky Creek, a tributary to the Clearwater River. The project was initiated in 2017 to reduce sedimentation, to eliminate direct threats of recreational use of the area on bull trout habitat, and to monitor the response of the bull trout population.

Rocky Creek bull trout cumulative effects model and threat summary

Description

Alberta's fisheries cumulative effects modelling approach (Joe model) was used to assess the threats to bull trout in four Clearwater River watersheds (Rocky, Elk, Cutoff and Limestone creeks). The bull trout Joe model is a semi-quantitative cumulative effects model that combines 18 different threats and was populated with data specific for each of the four watersheds. This report documents the rationale for the relationship between the modelled stressors and predicted bull trout system capacity (stressor-response curves), describes the data used to populate the stressor input values, and provides a short summary of stressors and model outputs for each of the four study watersheds.

Land use, climate change and ecological responses in the Upper North Saskatchewan and Red Deer River Basins : a scientific assessment

To inform future land use planning in the Eastern Slopes of west-central Alberta, a review was conducted of key land use stressors and expected ecological responses. Altered fire regimes, forest... More ≫

Description

To inform future land use planning in the Eastern Slopes of west-central Alberta, a review was conducted of key land use stressors and expected ecological responses. Altered fire regimes, forest harvesting, and linear disturbances are key stressors that, along with climate, and other environmental drivers, affect wildlife, hydrology, and other valued ecosystem attributes. The current status of each stressor in the study area was characterized from geospatial and other environmental datasets, expected ecological responses were summarized from reviews of the published literature, and future research and monitoring priorities were identified.

Description

The primary objective of the study was to provide a summary of the diet data and any major patterns in the diet of fish from waterbodies within the study area. The analysis included the three diet content methods used (frequency of occurrence, percent composition by count, and percent composition by weight; see Section2.1 for details) and presentation of temporal (years and where appropriate months) and spatial patterns for the fish species among the river systems.

Description

Presents findings of a survey of five bull trout spawning tributaries of the upper Clearwater River to describe the physical characteristics of the spawning sites, and determine if environmental conditions were limiting to egg and alevin survival at these sites. A previous study had showed that these spring streams, characterized by stable water flows and stable water temperatures, provide 90 per cent of the known spawning areas for bull trout in the Clearwater River.
