Moose Winter Tick Survey Program 2023

A message from the BC Government’s Winter Tick Survey Program.

We’re back!

Hello again everyone and welcome to the first email of the 2023 BC Moose Winter Tick Surveillance Program! We are excited to be getting started again and looking forward to the eight year of this program. 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 below message on websites, social media platforms or in newsletters.

BC Moose Winter Tick Surveillance Program

Program Information (For those who are new to the program)

The BC Wildlife Health Program is looking for your help reporting observation of healthy (no hair loss) and infected moose (with hair loss). Hair loss is caused by “Winter Ticks” on moose.  The Moose Winter Tick Surveillance Program wants to collect observations to monitor the number of animals with or without 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. Please find the latest report attached to this email.  

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.  

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
