Alina Fisher, BSc MA (Comms) PMP, Ph.D. Candidate, University of Victoria, was the most recent recipient of the Dr. Ian and Joyce McTaggart Cowan Scholarship in Environmental Studies at the University of Victoria. Alina has an extensive background in wildlife biology, ecology, and science communication, coupled with an incredible sense of compassion and empathy for wildlife, urban and otherwise.
The UWSS is so fortunate to have Alina working with us. She has guided our public education and communications with a compassionate, measured, and even hand; always listening to and respecting multiple perspectives. We are excited for Alina as she pursues her Ph.D., and are grateful for her expertise. She has been instrumental in helping communities have a better understanding of the role, and need, for urban wildlife.
Research elsewhere has demonstrated that slower streets are safer, more livable streets for everyone—pedestrians, cyclists, children, dogs and cats, and urban wildlife, like deer, reducing both the number and severity of collisions with vehicles.
It’s a growing trend in cities around North America, including Vancouver and Toronto. According to research cited by the District of Saanich’s Engineering Department, when a vehicle is travelling at 30 km/h or less the probability of a road user surviving a collision with a motorist is nine out of 10, versus a survival rate of only two in 10 when the vehicle is travelling at 50 km/h or more.
Kudos to Victoria and Saanich Councils for taking this significant step toward safety. The municipalities represent more than half the population of this region.
And now Oak Bay Council has also signed on for 30km/h speed limits on side streets!
Esquimalt, Sidney, Central Saanich and North Saanich were all ready to join a 40 km/h regional pilot last fall when Saanich proposed it but subsequently Saanich Council shifted to a lower speed target when residents asked for a more ambitious approach to safety.
Here’s hoping that those municipalities follow Victoria, Saanich and Oak Bay for a 30 km/h side street speed limit in their communities, too, because slower really is safer for all of us, no matter where we live in this wonderful region
A series of thefts of vital research equipment in Oak Bay threatens the ground-breaking urban deer management project. Since early December, 13 specialized wildlife cameras out of the 39 associated with the project have been stolen from locations around the municipality. The cameras play an important role in the project that is aimed at managing the indigenous urban deer population in Oak Bay by collecting data that attests, over time, to the density, movement patterns, population size and habits of Oak Bay deer.
The three-year initiative, a partnership between the District of Oak Bay and the Greater Victoria-based Urban Wildlife Stewardship Society (UWSS), is using an immunocontraceptive (IC) to trial the humane and effective reduction of the municipality’s indigenous Columbian black-tailed deer population. It is funded by Oak Bay and the Province of BC’s Provincial Urban Deer Cost-Share Program. The project is currently at the halfway mark.
The immunocontraception approach reduces the number of fawn births each year in a way that does not open up territory for new deer to move in and replace them the way population culls do. If successful, the project will make available a new community-based approach to urban deer management to communities throughout North America. The project is endorsed by the BC SPCA.
Preliminary results indicate that the application of IC to 60 does in the Fall of 2019 has significantly reduced the deer birth rate in Oak Bay in its first year. Data from the cameras is critical to proving, up to scientific research standards, the success of the project.
The 13 cameras, Bushnell Model 119876C [See photo below], are owned jointly by Oak Bay and the UWSS. The 13, stolen mainly from public property, are valued at a total of approximately $4,000. Nine were stolen in the first half of December and another four since then. The scale, breadth and timing of the thefts, along with the specific locations chosen, suggests a targeted campaign rather than a series of random acts.
Oak Bay Police are investigating. Residents who have observed individuals removing tree-mounted cameras from property or associated activity from early December to present, particularly on public property, or who may have security camera footage, are asked to contact OBPD at (250) 592-2424. Anyone who has come across the sale or donation of Bushnell wildlife cameras since December or in the future should also contact Oak Bay Police.

Do you want to know about Lyme disease and the risk of getting this disease from ticks? For many of us that migrate here from Eastern Canada, we hear a lot more about Lyme disease as it is much more prevalent there, and actually on the increase. However, here in B.C., the rate of Lyme disease in humans remains consistently very low at less than 1% in adults (<0.5/100,000 population).
The ticks that transmit Borrelia burgdorferi, the bacterium that causes Lyme disease, fall into two main categories, Ixodes pacificus (Western Black-Legged Tick) on the West Coast of North America, and Ixodes scapularis (Black-Legged Tick) in the Northeastern U.S.A. and Canada. Unlike in Eastern Canada, the rate of Lyme disease remains low in B.C. for several main reasons:
The prevalence of B. burgdorferi in ticks in B.C. has remained consistently low over time, with less than 1% of ticks tested carrying the bacteria. This is different than the Eastern portion of N. America where Lyme disease rates in both ticks and humans have increased over time along with climate change.
The Western Black-Legged Tick are less capable of carrying B. burdorferi than the Black-Legged Tick in Eastern Canada and the U.S.A.
The animals on which Ixodes ticks feed are different. In B.C., the ticks primarily feed on small rodents such as deer mice and dusky-footed woodrat. In Eastern Canada and the U.S.A., the ticks feed on white-footed mice and white-tailed deer.
The vegetation and climate are different between B.C. and Eastern Canada (e.g. B.C. has mostly coniferous forests, whereas Eastern North Amercia has mostly leafy forests).
Despite Ixodes ticks being present throughout southern and central B.C., including in most of the highly-populated areas, an expansion of the range of these ticks, which could occur with climate change, would not greatly increase the number of people exposed in B.C. since the expansion of the range would be to less-populated areas.
To sum it up, the risk of Lyme disease in B.C. is lower and more stable than it is in Eastern Canada and in the Northeastern U.S.A.
That said, it is always important to protect yourself from being bitten by ticks, especially while out hiking. Check out the BCCDC website for more information.
Out of concern for Lyme disease, some people have asked about the number of ticks seen on deer through the course of our research project. During the UWSS’s deer contraception project, there were very rare instances of ticks seen on the deer that were handled. In fact, none were seen during the latest Fall of 2020 portion of the project. So, though deer management is on the mind of many people in Greater Victoria, at least the risk of Lyme disease does not need to be part of the concern.
As 2021 has begun, we’re wishing everyone a safe and healthy start to the New Year!
With the darker, wetter days and nights, you may feel that you’re seeing fewer deer…the official term for that appears to be “hunkering down”! Like us, deer tend to look for warm, dry shelter where their needs can be met, and as a result they seem to be less visible.
Watch for deer crossing
We’re glad to note that some actually are a bit safer when crossing the road – 60 does that received their IC in the Fall all have reflective tape on their identification ear tags, and we’ve heard that they are quite visible in headlights.
Theft of wildlife cameras
Sadly, in the first couple of weeks of December, nine of the wildlife cameras collecting data on urban deer in Oak Bay were stolen. The cameras were all on public land with permission from Oak Bay and are the property of Oak Bay and the UWSS. If you saw someone removing a camera from its location (likely a tree), please report to the Oak Bay Police (250-592-2424).
Injured buck recovering
You may have seen a recent photo in the newspaper of a majestic buck with an arrow in its side, just behind its right foreleg. The suffering buck had been shot, likely in Oak Bay, with a crossbow, clearly with the intent to kill.
Thankfully, a number of people reported the injured deer to the Conservation Service, and with the help of UWSS past president Bryan Gates and our wildlife veterinarian Dr. Adam Hering, they were able to locate the buck and successfully remove the arrow. The arrow just missed the buck’s heart but when last seen appeared to be doing quite well.
It is illegal to hunt within urban boundaries. As well, urban deer eat many plants that have pesticides on them and the meat is unfit to eat. As well, does that have been given immuno-contraception have a small, yellow provincial tag in one ear that identifies them as unfit for meat. If you see anyone attempting to hunt within urban boundaries, or you see an injured deer, please call the Conservation RAPP line at 1-877-952-7277 or #7277 on Telus mobility.
The native deer species here in greater Victoria is the Columbian black-tailed deer. But our lead scientist Jason Fisher and colleague Cole Burton have a new paper in the journal Ecology and Evolution on white-tailed deer in north-eastern Alberta.
They found that oil and gas features play a key role in sustaining the expansion of white-tailed deer northward into boreal landscapes. The infographic, right, explains the key findings of the paper.
