Deer counting

Knowing how many deer use an area is important to determine how to manage populations for sporting or conservation purposes.

Deer populations are usually estimated using either direct observation counting or indirect counting methods.

A deer manager will get more value from a deer census if the data is used together with information such as the condition of the habitats.

Direct observation counting

Direct observation counts can provide deer managers with a snapshot of a population within the count area on a particular day or night.

Counts can begin to show population trends when the same method is used several times – especially if carried out over large areas in a short time frame.

Direct counting methods include:

  • ground counting by teams on foot
  • aerial counting using helicopters or fixed wing aircraft
  • night-time ground counting using thermal imaging cameras

You should consider local conditions to decide on the most suitable method to use.

Indirect counting

Deer managers can assess deer numbers using indirect methods such as dung counting where direct observation is difficult.

Dung counting involves assessing how much dung is deposited over a period of time in a specified area to estimate deer usage of the area. This method was traditionally used in woodland areas only. Some deer managers are now choosing to use specially designed versions of this method over open ground.
