Habitat Restoration Plan for the Vancouver Island Ringlet (Coenonympha tullia insulana) at Rithet’s Bog, Saanich B.C.
No full textRithet’s Bog is an area rich in ecological diversity. It is the last remaining peat bog within the Saanich Peninsula, and as such hosts an array of rare species, of wildlife and plants alike (Golinski 1995, 1997, Green 2006). The region has undergone tremendous change within the last century, and pressures from intensive agricultural use followed by rapid urbanization have impacted the health and structure of the bog ecosystem. From the moment it became a park in 1994, restoration efforts have been directed at preserving the sensitive wetland habitat required by many different species. One of these species is the Vancouver Island Ringlet (Coenonympha tullia insulana), a butterfly that is considered as critically imperiled (red listed) across British Columbia (B.C. Conservation Data Centre, 2013). Although the Rithet population numbers have been stable over the last few years compared to others in the Victoria area (Miskelly, 2007, Hartwell, 2010), their main habitat patch is currently being threatened by reed canary grass (Phalaris arundinacea) and other invasive species. As such, there is a need for a habitat restoration plan to be implemented, followed by a monitoring regime in order to assess the effectiveness of the restoration activities. The following report describe the different steps and methods taken in order to draft the habitat restoration plan. Methods included a systematic butterfly survey conducted every 2 weeks from April to August 2018, Terrestrial Ecosystem Mapping (TEM) of the main habitat area along with the proposed restoration site, and repeat photography in order to assess changes in vegetation and water levels. Over the course of the survey period, 43km of trail were surveyed, spanning over 1000 minutes of observation time. A total of 243 butterflies were observed, from nine different species. Out of those, 82 were Vancouver Island Ringlets. Repeat photography emphasized the dry conditions over the summer period, and the need to have a more permanent water source, while TEM highlighted some of main herbaceous plants and grasses which currently thrive within the butterfly habitat area. Proposed restoration activities for this site include the construction of a butterfly nectar garden, composed of mix of larval host plants and adult nectar species, as well as educational activities and interpretive signage in order to inform the public about this unique habitat
Restoring native biodiversity within urban landscapes: A community restoration initiative to remove invasive species from an urban forest ecosystem in Esquimalt Gorge Park in Victoria, BC
No full textUrbanization continuously threatens native biodiversity through natural habitat alteration, decreased connectivity between remnant native habitats, and the introduction of exotic species. Urbanization’s ongoing pressures on remnant natural environments makes ecological restoration critical for the conservation of urban biodiversity. The purpose of this study was to remove invasive species, specifically English ivy (Hedera helix) and Daphne laurel (Daphne laureola), from an urban forest within Esquimalt Gorge Park in Victoria, BC. Invasive species removal from the western margin of the forest would hopefully increase species diversity and reduce future invasive spread into adjacent invasive free areas. A thorough terrestrial biophysical inventory was conducted of the entire forest study site, which included identification of all plant species present on site and a 1x1m quadrant analysis to determine species ground cover abundance. Observations along ten alternating belt transects resulted in identification of 41 species; eight of which were non-native/invasive species. Most abundant species were English ivy (Hedera helix), grass (various species), and trailing blackberry (Rubus ursinus) and the most widely distributed species were English ivy (Hedera helix), Himalayan blackberry (Rubus armeniacus), grass (various species), Oregon beaked moss (Eurhynchium oreganum), and trailing blackberry (Rubus ursinus). Following the biophysical inventory, the treatment site was selected based on the highest densities of invasive species. A Community Restoration Event was developed and on March 11, 2018, 11 volunteers gathered to remove invasives from the marked 360m2 treatment site. Following the invasives removal, it is recommended that native plants be seeded and planted within the treatment site and repeated removal of invasives occur to minimize potential species regrowth. Revegetation and reseeding with native plant species, as well as repeated treatments, are all viable options moving forward with the continued partnership and support of the Township of Esquimalt and the Gorge Waterway Action Society

Longing to Be Occupied : Trans Desire and Other Technologies of Violence
No full text*** Warning: the present memoir presents graphic descriptions of a sexual act some readers may consider violent and/or triggering. The author of the piece has expressed objections about the inclusion of such a trigger warning. We acknowledge and value his position even if we think it preferable to inform the reader. ***On the 6thday I was a woman in my bedroom I had two men over who referred to me as a she and believed in my she-ness more than I ever could. ‘Because they need to,’ Emily said. At first I thought that the fact that men, real men, were so easily convinced to make love to another man provided there be a few feminine props- I thought it incomprehensible. But is it not just as naïve to think a gay bottom sees manhood where there is nothing but an external version of himself?A week of faux womanhood has gone by and my head is over-boiling with good ideas, bad theories, and an uncontrollable need...
