- A restoration strategy to avert the projected ecological, social and economic risks of Lost Lagoon in Stanley Park, British Columbia
- The coastal saltmarsh that once made up Lost Lagoon was isolated into a freshwater impoundment to enable the construction of the Stanley Park Causeway in 1916. Water chemistry, water nutrients, and subsurface sediment were collected in August to October 2017, and it was concluded that Lost Lagoon is experiencing, low DO (average 6 mg/L), high salinity (0.9 ppt), high nutrient loading (TP 0.1 mg/L and TN 0.9 mg/L) and has elevated heavy metals (Cd, Cu, Ni, Pb, and Zn). A general biotic inventory was conducted and results indicated a lack of native species diversity and presence of invasive species, for both flora and fauna. Projected future conditions concluded that Lost Lagoon is prone to stratification and higher temperatures, which is expected to further water impairment including, increases in NH3 and toxic algae blooms. To mitigate this trajectory, a systematic restoration plan was developed to reintroduce tidal flushing into Lost Lagoon from Coal Harbour’s western basin, thereby restoring the degraded ecosystem into a diverse coastal saltmarsh. Hydrogemorphology and flow rates were estimated and as a result a 1.3-m wide water channel was recommended. A planting and long-term monitoring plan that will aid in revitalization of a coastal saltmarsh was developed, alongside a preliminary project budget and schedule. The project feasibility and public response were discussed as constraints, with emphasis on furthering this proposed restoration plan with professional engineering, and First Nations and public consultation., ecological projections, restoration, urban wetland, saltmarsh, intertidal ecosystems

- Restoring a culturally eutrophic shallow lake: Case study on Quamichan Lake in North Cowichan, British Columbia
- Quamichan Lake is a culturally eutrophic shallow lake located in North Cowichan on Vancouver Island in British Columbia. My research project examined the current trophic status and water quality of Quamichan Lake and investigated a number of watershed and in-lake restoration methods to return the lake back to mesotrophic (nutrient rich) conditions. Based on the data collected, Quamichan Lake is currently in a hypertrophic state caused by excess phosphorus inputs that leads to Cyanophyte phytoplankton species (cyanobacteria) to dominate during the summer. Eutrophication is both an environmental and human health issue as cyanobacteria algal blooms can disrupt the lake ecology and are toxic to most mammals. The goal of my research was to provide the Municipality of North Cowichan and Vancouver Island Health Authority with a comprehensive restoration plan to contribute to the restoration of Quamichan Lake and other lakes in southern Vancouver Island that are experiencing cultural eutrophication., © Kathleen E Moore, 2019.

- A riparian restoration plan for a construction site on the Brunette River
- Urbanization has altered riparian ecosystems, resulting in the decline of species that depend on them. The Brunette River in the Lower Mainland of British Columbia is no exception; though it currently supports a range of biotas, many of them are at-risk. These impacts are further accentuated by the expansion of the Trans Mountain Pipeline, which will result in the removal of a portion of critical habitat for the endangered Nooksack Dace. In light of the cultural significance of the basin to Kwikwetlem First Nations, the goal of this plan is to improve conditions at the project site post-construction through the establishment of culturally and ecologically important species and the addition of habitat features. I completed soil, vegetation, and water quality surveys to inform my prescriptions. Recommendations include the management of non-native species using manual and mechanical control methods and the planting of a native riparian community that fits within the confines of human infrastructure. A robust monitoring plan is also provided., critical habitat, exotic species, First Nations, restoration, riparian, urbanization

- Sturgeon Bank marsh recession: A preliminary investigation into the use of large woody debris as a tool for restoring a degraded foreshore marsh
- Large woody debris removal has been ongoing in the Fraser River Delta since the late 1800’s. I investigated how offshore winds and the absence of large wood may have contributed to the recession of the Sturgeon Bank Marsh. I suggest large wood increases marshland resilience and promotes new marsh establishment by attenuating wave energy, decreasing sediment mobilization, deterring herbivory, and promoting the establishment of vegetated islands from which the marsh can expand. I analyzed historical wind data for patterns in offshore wind duration and installed several pieces of large wood onto the tidal flats of the Sturgeon Bank. I developed a technique for anchoring wood in the intertidal and give my recommendations for further development. Finally, I conclude the recession of the Sturgeon Bank Marsh was the result of multiple interacting stressors and coin the term keystone structural element to describe the function of large wood within a foreshore marsh., large woody debris, keystone structural element, marsh recession, ecological restoration, wave sheltering, coastal marsh
