Opinion

DECISION AND ORDER

SAMUEL P. KING, Senior District Judge.

The Palila (Loxioides bailleui, formerly Psittirostra baillieui) is high on the [1182]*1182worldwide list of endangered species. The Palila was listed as an endangered species by the Secretary of the Interior in 1967, 32 Fed.Reg. 4001 (1967), and it still remains on the list of endangered species. 50 C.F.R. § 17.11 (1999).

The natural and only habitat of this Hawaiian honey-creeper today is a small area on the upper slopes from approximately 6000 feet to 9400 feet of 13,825-foot high Mauna Kea on the island of Hawaii. This area is about 10% of the bird’s historical range. When1 first officially identified in 1876, Palila lived only on the island of Hawaii but was common in north and south Kona and on the slopes of Mauna Kea in the Hamakua and Hilo Districts. By 1894, the birds were no longer found in Kona. Much of the extirpation may have resulted from avian malaria carried by mosquitoes whose population increased rapidly with ranching activities in the late nineteenth century.

By the mid-twentieth century, the Pali-la’s range had shrunk to its present area, largely due to habitat destruction from grazing ungulates (hoofed animals). Feral (wild) cattle, horses, sheep and pigs were established on Mauna Kea by the early 1800s. The feral cattle and horses were removed in the 1920s and 1930s, and feral pigs do not appear to have had a significant adverse effect on the Palila’s habitat. Feral goats appeared in some numbers in the 1930s, and mouflon sheep were introduced in 1963. An estimated 40,000 sheep roamed the mountain in 1936. In the 1960’s and 1970’s, the state maintained feral sheep numbers for sport hunting at about 3,000-4,000 animals.

The Palila is totally dependent on the mamane and mamane-naio forests for its existence. The bird’s preferred food is the pod of the mamane tree (Sophoro cryso-phylla), but it will also eat mamane flowers, buds, and leaves, and berries of the naio tree (Myoporum sandwicense), and sometimes insects when mamane pods are scarce. The bird also depends upon the mamane for shelter and nesting sites.

The feral goats and sheep had a devastating effect on the mamane forest. In 1977, the U.S. Fish and Wildlife Service officially designated the Palila’s critical habitat as a 200 sqkm ring around the upper slopes of Mauna Kea. 50 C.F.R. § 17.95 (1999). This area contains the entire known population of Palila and essentially encompasses the existing mamane and mamane-naio forests on Mauna Kea and is the remaining 10% of the Palila’s historical range.1 The U.S. Fish and Wildlife Service in its 1986 recovery plan for the Palila gave as the primary reasons for listing the Palila as an endangered species not only the bird’s low population but also that a significant portion of its historical range was no longer occupied by the Palila and that its then habitat was being adversely modified by feral ungulate browsing.

Believing that the Hawaii Department of Land and Natural Resources (DLNR) was violating the Endangered Species Act, the Palila and its supporters brought suit to require the removal of the goats and sheep from the Palila’s critical habitat. That action resulted in an order filed August 1, 1979, so requiring except that it was limited to feral goats and feral sheep. Palila v. Hawaii Dep’t of Land and Natural Resources, 471 F.Supp. 985 (D.Haw.1979) (Palila 1).

At the time Palila 1 was being litigated, Jon G. Giffin, Wildlife Biologist in the Division of Forestry in the DLNR, was studying mouflon sheep and their impact on the critical habitat of the Palila. In deference to Mr. Giffin, and the claims of hunters that mouflon sheep did not present the same potential for harm to the Palila’s critical habitat as did the feral sheep, the then plaintiffs specifically excluded mouf-lon sheep from their prayers for relief.

[1183]*1183The European mouflon (Ovis musimon) is a native of Corsica and Sardinia. The sheep are light tan to rich brown, with white on the tail, rump, and underparts, and they have large horns of excellent trophy quality. The State Division of Fish and Game introduced the mouflon onto Mauna Kea with the original hope that they would upgrade the existing feral sheep and modify some of their undesirable characteristics. A total of 99 hybrid and 94 pure mouflon were released between 1962 and 1966. However, the hybridization project was never completed. The pure mouflon became exceedingly popular with hunters because of its excellent sporting, meat, and trophy qualities. Therefore, to accommodate the hunters, the DLNR was maintaining á pure mouf-lon population within the Mauna Kea Game Management Area, which area included most of the Palila’s critical habitat.

The mouflon sheep study was finally completed, and on the basis of the findings of that study the plaintiffs refiled an action similar to their earlier action but this time aimed at the mouflon sheep. Not surprisingly, the study found that pure mouflon sheep presented the same danger to the Palila’s critical habitat that feral sheep or hybrid sheep did. Accordingly, this court in 1986 entered another order filed January 27, 1987, reaffirming the order of August 1, 1979, and requiring the removal of pure mouflon sheep and hybrid feral/mouf-lon sheep. Palila v. Hawaii Dep’t. of Land and Natural Resources, 649 F.Supp. 1070 (D.Haw.1986) (Palila 2).

The DLNR proceeded to carry out the court’s orders by a combination of staff hunting, unrestricted public hunting, and fencing. The staff, hunting included contracted hunting by helicopter. In the period July 4, 1987 to December 31, 1998, a total of 4,746 animals were harvested, consisting of 1,959 feral and hybrid sheep, 2,098 mouflon sheep, and 26 goats.

The record before the court does not indicate whether feral/hybrid sheep still exist within the Palila’s critical habitat in any significant numbers. An aerial survey conducted by helicopter on September 22, 1998 counted 180 sheep within the subject area. This number was not broken down as to the feral/hybrid sheep and mouflon sheep.

Goats are apparently not a problem any longer for the Palila on Mauna Kea. A July 1980 estimate of the feral goat population was less than 70. The last harvest of a goat is reported to have taken place in the period March 30-June 30, 1988. No goats are reported to have been harvested since then.

The eradication efforts pursuant to this Court’s order have had measurable success in improving the Palila’s critical habitat.

A comparison of photographs taken before the Court ordered eradication (pri- or to 1979) with those taken in recent months (1998) show extensive recovery of native vegetation. On the northern side of Mauna Kea, at the Puu Nanaha exclosure site, grasses and native shrubs have shown the greatest response to sheep removal which began about 20 years ago. Formerly barren areas are now vegetated with scattered Pukiawe (,Styphelia tameiameiae) and grasses. Mamane -recovery has been extremely slow on this side of the mountain even in exclosures that have been protected from sheep for 35 years. Mamane recovery- is more dramatic, however, on the warmer western slope of the mountain.
