| Specimen collection We conducted two major collecting trips to Tatlow Trail (February 3 and 11), as well as a few other subsidiary trips later in February. Starting at the head of Tatlow, we walked slowly and collected mosses along the trailside. There were some areas where we collected 5-10 m from the trail, mostly on veteran cedars, large rocks, or decaying tree branches. For each specimen, we took habitat photos, made careful habitat observations, and used sandwich bags for collection. These collections were then stored in a lab fridge back at UBC until they were keyed, dried, and submitted to the UBC Herbarium. Each of us was responsible for doing further research on 2-3 species (see the Species Accounts). Identification of species Identification of species was done at UBC with the aid of the following keys: Ellis, Shona (aka the Bryophyte Guru). Pojar, J., and MacKinnon, A. 2004. Plants of Coastal British Columbia, including Oregon, Washington and Alaska (revised edition). Lone Pine Publishing, Vancouver, Canada. Schofield, W.B. 2002. Field Guide to Liverwort Genera of Pacific North America. University of Washington Press, Seattle. Schofield, W.B. 1992. Some common mosses of British Columbia, 2nd ed. Royal British Columbia Museum, Victoria, Canada. Some species required more detailed keys for a confident identification. These and any additional sources are listed in the references section following each species report. Map-building During our collecting walks along Tatlow Trail, we noticed that certain spots represented the typical habitat of groups of species we were collecting and researching. We decided to build a map to show others these habitat examples. Once we had chosen the points along the trail that we wanted to highlight, we returned to the trail with a Garmin GPS unit and digital camera. We recorded the latitude and longitude for each point of interest and took photographs of the area. Then we acquired terrain resource information management sheets (TRIM) for Stanley Park from the provincial government. We imported these maps into ArcView (a Geographic Information System software), and built layers of trails, roads and perimeters for Stanley Park. The coordinates for the stopping points along Tatlow Trail were imported and superimposed on this map, then labelled using a drawing program. HTML links to pages describing the stops and showing pictures of the exact habitat we were highlighting were then created from these labels to produce the interactive map that you see on this website.
