Deer were increasing, in part because few cougars or other predatory animals had been seen in the park for several years. They became quite tame by midseason, a fact which unfortunately makes such of them as do not hibernate within the park easy game for hunters. Deer have been exceedingly abundant. Several elk., progeny of the herd transplanted into Klamath County, have been seen occasionally. Foxes, timber wolves, and coyotes were not uncommon sights, and one cougar was reported.
Small game is present in countless numbers.
The ranger force is, however, not sufficient to adequately patrol the 249 square miles of park to protect against poaching. The park continued to encourage the growth of the bear population in part as a tourist attraction. As a result of such contact the bears, according to the superintendent, were becoming docile and fearless, thus leading to their destruction by hunters outside the park boundaries. This development led to a successful Park Service effort to have the Oregon state legislature enact legislation in 1925 declaring an eleven-month closed hunting season on bear in Jackson, Josephine, and Klamath counties surrounding the park. By the late 1920s park wildlife was thriving as a result of the aforementioned legislation, favorable weather and forage conditions, and management policies.
