How Big Is a Buck's Home Range?

A Penn State deer researcher says the rule of thumb that a buck's home range is one square mile is most often wrong. In his Pennsylvania data, an average buck used about half a square mile in fragmented Gettysburg and about two in the big woods. One collared buck covered 85 miles in 24 days of the rut.

The study

Pennsylvania: farm country against the big woods

WhereGettysburg and Susquehannock State Forest, PennsylvaniaSampleGPS-collared deer, number not given
What they did

Compared average buck home ranges in fragmented Gettysburg with the big woods of Susquehannock State Forest.

What they found
  • The researcher's words: "the rule of thumb that a buck's home range is one square mile is most often wrong."
  • In Gettysburg, an average buck home range was about half a square mile.
  • In Susquehannock State Forest, an average buck home range was about two square miles.
  • In both places, an average buck range took in about 2 doe home ranges.
Limits
  • A research blog post, not a paper.
  • The post doesn't give the number of deer or the season for these averages.

Big woods bucks in November

WhereLarge tracts of contiguous forest, PennsylvaniaSampleGPS-collared deer, number not given
What they did

Tracked buck home ranges through the fall in big, unbroken forest.

What they found
  • In November, buck ranges grew to nearly three times larger and averaged almost 3 square miles.
Limits
  • A research blog post, and the sample isn't stated.
  • Big woods deer only. The author says other parts of the state differ.

02My read

MY READMy tactic, not a study result

On a small property, you're not hunting his whole range. You're hunting the spot where he crosses yours.

That's how I hunt it, not something these studies tested.

03Field notes

  1. Don't plan around the one-square-mile rule. In this Pennsylvania data, an average buck used about half a square mile to about two.
  2. On a small property, find the spot where his range crosses yours and hunt that.
  3. Check your own state's season dates and legal hours with your state wildlife agency.
