Abstract: Established in <strong>the</strong> early 1970’s, <strong>the</strong> regulation <strong>of</strong> cougar harvest through hunting<br />

seasons and quotas contributed to increases in cougar abundance and distribution in most<br />

western states during <strong>the</strong> past 30 years. Today, 10 <strong>of</strong> 12 western U.S. states regulate cougar<br />

harvest through hunting seasons and quotas, which vary by state, year, and in season length and<br />

quota numbers. California prohibits cougar hunting and Texas allows unlimited hunting and<br />

<strong>the</strong>refore lacks regulations. Three <strong>of</strong> 11 states that allow cougar hunting regulate <strong>the</strong> harvest <strong>of</strong><br />

female lions through subquotas. Two states that do not regulate female harvest do not allow <strong>the</strong><br />

use <strong>of</strong> hounds for hunting cougars. Hunting regulations in 9 <strong>of</strong> 11 states prohibit killing spotted<br />

kittens and females with spotted kittens. Only one state, Montana, requires hunters to backtrack<br />

lactating females that have been killed in order to locate dependent young. While regulations<br />

prohibiting <strong>the</strong> take <strong>of</strong> maternal females and affording protection to nonmaternal females through<br />

subquotas should remain in place, little information has been provided to hunters, guides and<br />

outfitters, or state managers on <strong>the</strong> proportion and movements <strong>of</strong> lactating and maternal females<br />

which may be encountered during hunting seasons. We examined reproductive data for a<br />

moderately hunted cougar population (1988-1992) and a primarily non-hunted population (1998-<br />

2002) on <strong>the</strong> Nor<strong>the</strong>rn Range <strong>of</strong> Yellowstone National Park. Proportion <strong>of</strong> females with<br />

dependent (pre-dispersal) <strong>of</strong>fspring was calculated across winters. We summarized breeding,<br />

denning, and lactation chronology for maternal females from both study periods. Peak breeding<br />

occurred in March through May and denning followed approximately 3 months later, peaking in<br />

June through August. Given a 4-month lactation period, proportion <strong>of</strong> lactating females (n = 19<br />
