There are an estimated 400 000-550 000 km of unpaved resource roads in British Columbia. These roads are used for forest, mineral, and energy development, commercial and public recreation, and in some cases for access to private land holdings. This literature summary lists road effects on terrestrial and aquatic wildlife, plant communities, and physical elements found across landscapes in British Columbia. These effects may be local or may apply to large areas. Road effects can occur during construction or with subsequent road presence, upkeep, and use. Also summarized are recommendations meant to reduce negative road effects. These include taking a strategic approach to road and access management, using structured road planning methods and tools, implementing mitigation techniques, and following up with effectiveness monitoring and reporting. The summary also provides recommendations for further studies of road effects.
Future Research Suggested by Project
- Evaluate effectiveness of post-wildfire road treatments.
- Examine how the impacts of road projects are addressed and documented during environmental impact assessments.
- Foster collaboration to address the scientific findings, complexities, pressures, and choices related to road access management.
- Develop tools/models and low-impact road construction and removal techniques.
- Examine road effects over time and space.
- Study the spread of exotic plant species along roads.
- Plus other research needs identified on page 78 (Table 6) of the paper.
