Community Science

Democratizing science and contributing towards the collective knowledge of wildlife

What is Community Science?

Community science (also referred to as "participatory science" or "citizen science") is the collection, and sometimes analysis, of data by members of the public. It provides everyone, regardless if they are a professional scientist or not, an opportunity to learn about something they are passionate about while also contributing towards our collective knowledge of wildlife. Community scientists help to advance scientific research by improving the scientific community’s capacity and broadening the geographical scope.

Community Bat Program

At least eight species of bats live on the Thetis Island including the endangered Little Brown Myotis and the threatened Townsend’s Big-eared Bat. We participate in the BC Community Bat Program to educate Thetis Islanders about bat appreciation and the ecological importance of bats, what to do about bats in buildings and dead bats, and how to monitor for white-nose syndrome (a fungus deadly to bats and which has not been found yet in BC). Annual bat counts are carried out by volunteers at several locations four  times a year and the information is added to the BC Community Bat Program database. Bat boxes have been installed at several locations on the island.

Got Bats?

Bats are not only fascinating, but important. To learn more about bats and to find out what to do if you have bats in a building, find a dead bat, or encounter one in your home, click here for Bat FAQs or contact our Community Bat Program Coordinator, Rob at

Western Screech Owl Recovery

Western screech owls were once common in the Gulf Islands but have been impacted by logging and by the immigration of the larger barred owl into the region.  Specially designed nest boxes can assist with attracting the western screech owl back to an area. Our volunteers have installed approximately fifty next boxes on private properties throughout the island. The boxes are monitored for owl presence/absence twice a year using a wildlife camera on an extendable pole. The data is submitted to Madrone Ecological Consulting as part of a larger Vancouver Island/Gulf Island monitoring program.


Purple Martin Recovery

In 1985, only five nesting pairs of purple martin, the largest of the swallow species in North America, were left in British Columbia. Since then, conservation efforts using specially designed nest boxes have increased the breeding population to 1100 pairs, a precarious foothold. To assist with these conservation efforts, our volunteers built and installed six special-made nest boxes on pilings in Telegraph Harbour in the spring of 2020. To our delight, purple martins quickly moved in and raised young. Monitoring is carried out yearly. 

Forage Fish Monitoring

Forage fish such as Pacific sand lance and surf smelt are critical species at the base of  the marine food web, feeding larger fish such as salmon,  which in turn feed marine birds, seals, sea lions and whales. Yet forage fish have not been well-studied and the locations of beaches where spawning occurs has not been well-mapped.  Our volunteer team samples local beaches each month and prepares the samples using specialized equipment. The samples are sent to the Mount Arrowsmith Biosphere Reserve Research Institute laboratory at the University of Vancouver Island where they are analyzed for the presence of forage fish embryos.

Sea Star Monitoring

Sea star wasting disease has decimated populations of many species of sea star over the past few years. Under the direction of Andy Lamb, a local marine biologist, volunteers count sea stars yearly at the waterfront near the Portal and at Clam Bay to monitor for recovery of the purple sea star.

Sharp-tailed Snake Monitoring

Sharp-tailed snakes (Contia tenuis) are small, shy snakes endemic to British Columbia and the Western United States. Adults average between 30 - 46 cm in length and are no wider than a pencil! Their small size and shy nature make them one of BC's most enigmatic reptiles, and their low and decreasing populations make them a red-listed species in BC.

For several years now, ThINC volunteers have been conducting frequent surveying trips to Moore Hill during the spring and fall in hopes of learning more about the species and its life history.
