Learning Activities
This course involves four hours per week of classroom instruction and three hours per week of field trips. Classroom work will include lectures and tutorials, and is integrated with textbook, scientific journal readings and case studies. The field trips are designed to complement the theory content of the course.
Course Description
This course examines cities and people’s lifestyles from an ecosystem perspective. The properties of the city as a natural environment are described. The impact of cities on surrounding natural environments and more remote ecosystems which serve as supply networks are explored. Global examples of urbanization are discussed in general and local examples are considered in detail. The theme of sustainability will be used to analyze options for change to protect and restore natural ecosystems.

- case studies e.g. Greater Vancouver Regional District Liveable Region Strategy, Georgia Basin Ecosystem Initiative
Learning Outcomes
Upon completion of this course, the student will be able to demonstrate a comprehensive understanding of the following:
- Major differences between the composition of natural ecosystems in an urban ecosystems.
- The variety of unique urban habitats created by urban development, the unique composition of urban flora and fauna, and how the urban environment effects their life histories.
- The impact of urbanization on biodiversity.
- Changes in surface and groundwater flows due to urbanization, and the changes to river and lake ecosystems which result.
- The types of water pollutants found in freshwater and marine environments of urban areas, and their effects.
- Stream and wetland care, stream habitat and water quality survey, sampling stream fauna and stream enhancement.
- Stream planning and development with reference to official community plans, zoning bylaws, design approvals, environmental design standards and construction management.
- Greenways planning with natural systems, practical benefits of community greenways, planning for community greenways, greenways implementation and greenways management.
- Caring for wildlife habitat at home with reference to components of wildlife habitat, wildlife shelters, theme gardens – hummingbirds, butterflies, songbirds and co-existing with wildlife-windows, conflicts.
- Land use planning and how it can be used to reduce the impact of cities on natural ecosystems.
- The concept of sustainability and the major components of sustainable communities in terms of protecting and restoring local natural ecosystems.
Means of Assessment
| Midterm examination | 25% |
| Final examination | 25% |
| Field trip reports | 30% |
| Term project | 20% |
Notes:
- Field trip reports will consist of 5 reports worth 5 marks each involving analysis, and 5 worth 1 mark each that are descriptions of site visits.
- The final exam will be comprehensive and cover the entire course.
- The term project will include an oral presentation and a paper.
- For Habitat Restoration Program students, 15 marks of the 30 for field trips will be assigned to a habitat restoration project. Three of the BIOL 2302 field trips will become optional for HRP students.
- HRP students will be required to design a community based habitat restoration project in consultation with a community group, government department or other client for 15 marks.
- HRP students will be required to conduct their major 20 mark project on a wetland topic applied to a local situation.
