A message from Kevin Watt, Program Coordinator for the 2021 Moose Winter Tick Surveillance Program.

Moose Tick poster

Hello again everyone and welcome to the first email of the 2021 BC Moose Winter Tick Surveillance Program!

We are excited to be getting started again and looking forward to the seventh year of this program. Last year was a good year with over 400 surveys submitted, check out the latest report on the website ( This year we are looking to do even better. We are asking for your help to spread the word about this program and encourage people to document and share their moose observations with us. We welcome you to share the message below on websites, social media platforms and/or in newsletters, as well as the poster (see attachment).

For those of you who are new to the program, the information below outlines what this program is all about:

The BC Wildlife Health Program is looking for help from wildlife professionals, wildlife enthusiasts and the general public with observations of hair loss caused by “Winter Ticks” on moose throughout the province.  The Moose Winter Tick Surveillance Program wants to collect observations to monitor the number of animals with hair loss and the amount of hair loss on each animal to estimate winter tick prevalence and distribution.  This program occurs on an annual basis.  Winter ticks are a significant parasite for moose populations and can contribute to moose declines in parts of their range, including BC.  So, it is an important health factor to monitor, particularly with climate change and alterations to moose habitat.  The findings of the surveillance program will contribute to the Provincial Moose Research Program, which was initiated in 2013 to investigate factors influencing moose populations in BC.  This is the seventh year of the program; last year we received 426 reports of moose from across the province.

Winter tick infestations can be observed on moose during January through April.  The ticks spend the entire winter on one moose and there can be as many as tens of thousands on one individual.  As the female ticks become adults they feed on blood in late winter and the irritation causes moose to scratch and groom themselves excessively, resulting in hair loss.  The extent of the hair loss is a rough indicator of how many ticks are present and can be observed easily from a distance.  We know that tick infestations can result in behavioral changes or direct health impacts that may reduce moose survival.

We hope that you may be interested in contributing to this surveillance program by recording your observations of both healthy and infected moose during the winter and spring.

It would be great if you could carry this survey with you while you are out in the field this winter/spring when tick infestations become visible.  Please document all moose observations, from January 1, 2021 to April 30, 2021, regardless of hair loss or not. Also, it would be appreciated if you could distribute this email to anyone who will be spending time in the field this winter/spring.

Your participation is greatly appreciated!
