Blanket Creek Provincial Park weedy field restoration plan
A key management concern for provincial parks is the establishment of invasive species due to their impacts on native biodiversity. Within Blanket Creek Provincial Park there is a 0.24 ha heavily invaded field dominated by hawkweed species and spotted knapweed which developed after a series of natural and anthropogenic disturbances. Restoration actions are required to renew the ecological process of natural succession and shift the vegetation community from its current state to one dominated by native species. The aim of this project was to determine the current site conditions which will inform a restoration plan for the site and act as baseline conditions for future monitoring. This site assessment focused on the characterization of the vegetation and soil conditions. Restoration recommendations focus on promoting the development of a deciduous forest characteristic of the Interior Cedar-Hemlock biogeoclimatic ecosystem classification zone. The restoration recommendations include invasive species management, decompaction, fertilization, mulching, and the planting of native trees and shrubs., restoration, alternative stable states, invasive species, forest succession
Exploring the relative effects of different wetland restoration sites on functional connectivity for the northern red-legged frog (Rana aurora)
Amphibian species are globally at risk, with a leading cause of decline attributed to habitat loss and fragmentation. The northern red-legged frog (NRLF) is one such species and listed as a Species of Special Concern by the Species at Risk Act. The Sunshine Coast Wildlife Project is creating new wetland habitat on the Sechelt Peninsula. In this research, I provide a tool to explore the relative effects on the functional connectivity of different potential restoration sites. A habitat suitability model (HSM) was created to describe the landscape in terms of conductance, or ease of movement for NRLF. Using this conductance map, I analysed the functional connectivity between wetlands by using Circuitscape, a software grounded in circuit theory. Three potential restoration options were compared against the existing landscape. Of the three options, one had a much greater effect in increasing the overall wetlands and its connectivity to the existing network of wetlands., Functional connectivity, wetland habitat restoration, northern red-legged frog (Rana aurora), circuit theory, Circuitscape, habitat suitability model (HSM)
