 In March 2016 we conducted a total count survey to assess the current population status of the heart-south and parsnip caribou herds. Our primary objective was to count the total number of caribou and identify the proportion of calves in each herd. We compared the data collected in 2016 with past estimates to assess population size trends over time. The black line shows the boundaries of the management units, the blue lines show the census blocks, and the brown line shows the flight path of the survey. Ministry biologists have been monitoring the heart-south and parsnip caribou herds since the late 1990s. Long-term trend data suggest both the parsnip and the heart-south herds have declined by 45 to 50 percent since 2006. Calf survival appears to be low in the heart-south and the herd may continue to decline. Caribou and the heart ranges are on the provincial red list in British Columbia. A number of management actions have been implemented to support mountain caribou recovery in the parsnip and the heart-south herds. Ongoing management actions promoting recovery are essential to ensure the persistence of these herds in the long term. Continued monitoring of the heart-south and parsnip caribou herds is essential to determine population status and assess recovery actions.
