This article is a continuation from Part 1 about our December 2015 family vacation to the Vancouver, British Columbia, area.
The trip was also an opportunity for me, as a Canadian Museum of Nature volunteer for Paul Hamilton in the museum’s diatom lab, to collect Western Canada and “urban” freshwater diatom samples in the Vancouver area.
The following are some of the best sample locations and examples of diatoms found, from 20 samples overall.
Stanley Park: Lost Lagoon
Our kids Sheila and David again assisted me with sampling, this time in Stanley Park and West Vancouver. We entered the park and took a sample from the picturesque Lost Lagoon Lake and the creek that flows into it from the west.
Stanley Park: Beaver Lake
Beaver Lake is near the centre of Stanley Park. It is drained by a creek that flows east through dense forest to Burrard Inlet. The Ravine Trail follows the length of the creek. Samples were collected from both the lake and the creek.
West Vancouver: Capilano River
Because of a wrong turn in Stanley Park, we found ourselves crossing the famous Lion’s Gate Bridge into North and West Vancouver. It provided an opportunity to get a sample from the Capilano River, which divides the two cities.
Burnaby: Still Creek
On a rainy day, I took the SkyTrain southeast to Burnaby where, according to the map, there appeared to be some more interesting lakes and creeks. Once above ground, the SkyTrain gives you a feeling of travelling in a low-flying airplane. From the Sperling-Burnaby Lake station, I crossed a pedestrian overpass over a railway line to the Sperling Bike Trail. I took samples from the nearby Still Creek and from drainage ditches along the trail and Sperling Avenue.
Sperling Avenue Ditches
Further south on either side of Sperling Avenue were drainage ditches with plenty of water. There was also a swamp. These were all ideal places for diatoms.
I took two samples from Burnaby Lake. The first sample was at the Rowing Pavilion. Because of swampy ground and elevated walkways, I took a sample from under weeds by the shore. A second sample was taken just off the Southside Trail in a more accessible spot. There, the bottom was rich with black muck—perfect for diatoms. Both Burnaby Lake samples contained many diatoms of various species and were the best of the trip.
Overall, we had a very enjoyable family trip to Vancouver, as well as a successful one collecting diatom samples. I am planning a future trip there for live diatom samples, with possible side trips to Victoria and Mission. Sheila may also be able to send us live diatom samples from B.C. in the spring or summer for analysis.
