UWSS Research

Have you noticed some of the deer in Oak Bay wearing some radio collars like this one? That is because we’re currently doing a two-part study on the population of deer in Oak Bay. The first part of the project is going to give an accurate measure of the population of urban deer in oak bay. This will include analyzing the movement of deer – do they have large home ranges? Do they wander or are they staying in a relatively small area?

The second part of the study will be to assess the effectiveness of using an immunocontraceptive vaccine as a non-lethal method of population control.

This study is funded by the Province of British Columbia, the Municipality of Oak Bay, and donations from our supporters. Our methods have undergone rigorous review and meet regulations put in place by the Canadian Council on Animal Care and BC Fish and Wildlife. Our project is also endorsed by the BC SPCA.

Oak Bay Deer Project

The results are in! As the 2019 Preliminary Report indicates, there are only approx. 100 deer in all of Oak Bay. Interestingly, deer don’t move around very much and have relatively small home range sizes. We’ve also identified some areas of high use in Oak Bay, where the deer like to congregate.

This gives us important information about where immunocontraception is likely to be most effective, and where Oak Bay can target its management efforts to best effect.

Esquimalt Deer Project

The 2019 Report is the second year of a 3 year monitoring project in Esquimalt. The methods used in Esquimalt aren’t as precise as the ones used within Oak Bay, but still allows a baseline monitoring of the deer population within the Township. Interestingly, there was no increase in the number of deer between this year and last year, indicating that deer population numbers are quite stable.

Esquimalt is awaiting results of the immunocontraception program in nighbouring Oak Bay and hopes to target its management efforts to best effect.
