Ecological Monographs, 81(2), 2011, pp. 215–239 2011 by the Ecological Society of America See complete pdf file:Watson&Estes 2011 Abstract. We used the extirpation, reintroduction, and spread of sea otters (Enhydra lutris) along the west coast of Vancouver Island, Canada, to evaluate how the otter–urchin– algae trophic cascade creates variation in rocky reef community structure
Here are a few examples of how the Friends of Ecological Reserves has provided research grants to support biological and ecological research projects related to ecological reserves in British Columbia. Some of the projects that have or are being supported are profiled below. What Lies Below at Baeria Rocks Ecological Reserve 2016 : The Friends

From: THE LOG FRIENDS OF ECOLOGICAL RESERVES NEWSLETTER AUTUMN 2008 By Jane Watson Dear Friends, This year, with support from the Friends of the Ecological Reserves, we completed our 22nd season, studying sea otter community ecology in Checleset Bay Ecological Reserve. Checleset Bay Ecological Reserve was established in 1981 to protect habitat for a fledgling
ABSTRACT We estimated carrying capacity for sea otters (Enhydra lutris) in the coastal waters of British Columbia, Canada, by characterizing habitat according to the complexity of nearshore intertidal and sub-tidal contours. We modeled the total area of complex habitat on the west coast of Vancouver Island by first calculating the complexity of the Checleset Bay–Kyuquot
The red turban snail (Astraea gibberosa) as a model species to study how sea otter predation affects prey populations. September 28, 2006 Dear Friends, We spent our field season divided between Bamfield Marine Sciences Centre and the community of Kyuquot in Checleset Bay. In our ongoing research we have been using the red turban snail
An assessment of abundance and growth of the sea otter population (Enhydra lutris) in British Columbia By Nichol, L.M., J.C. Watson, G.M. Ellis, J.K.B. Ford Abstract Sea otters were re-introduced to British Columbia from Alaska between 1969 and 1972. The first population count was made in 1977. Since 1988, field surveys have been undertaken using small boat or helicopter,
Jane Watson ‘s 2000 report to NRC Canada, with a thankyou note to Ecological reserves. It includes the status of sea otter populations and the effects on abalone and the history of abalone fisheries within the historic range of sea otters.

Since the provincial government does not have jurisdiction over fishing, the waters of Race Rocks and some other marine ecological reserves are protected by the Federal government’s Rockfish Conservation Area strategy. This program prevents fishing in the reserve. The problem is that it may not be permanent, so continued protection of all of the organisms

This study By Jane Watson in 1991, provides the first direct quantitative observations on the effects of sea otter foraging on nearshore community structure. It also examines temporal variability in species abundance at sites with and without sea otters. see the complete PDF : sea_otter_foraging

Jane Watson submitted this report to Dr. Louise Goulet of Ecological reserves on the work conducted in 1987 and 1988 examining the community biology of sea otters in Checlesset Bay. PDF : sea_otter_community_ecology

Paul Breen, Trudy Carson, Bristol Foster and Anne Stewart did this report for DFO . In 1979 they visited the area known to be occupied by 55 animals in 1978 and made subtidal observations of the abundance and distribution of red sea urchins and found the red urchins to be scarce and restricted to crevices,
Anthea Farr, Alton Harestad and Lindsay Jones surveyed for sea otters off the West Coast of Vancouver Island from 14th to the 18th ofJuly , 1980 See complete PDF : sea_otter_survey_1980
