Information on Headwaters
'The Headwaters' is used by different groups to mean different areas of forest.
In this analysis we are using the
term to refer to the Headwaters Complex of two stands of old growth
(the Headwaters Forest, and the nearby Elk
Head Springs stand) and the intervening younger forest. There is also
some partially harvested old-growth in the intervening area.
The Headwaters Forest includes the largest stand of old-growth Redwood in
private ownership. It comprises some 2,755 acres of old trees, and approximately
1,800 acres of younger forest. Marbled Murrelets are frequently observed flying into
the forest, including birds showing "occupied behaviors" (indicative of nesting). Eggshell
fragments are also found here.
Elk Head Spring Forest includes 422 acres of old-growth, and approximately
700 acres of younger forest. Marbled Murrelets are again frequently seen in
the stand and are known to nest here. An active Murrelet nest was studied in
stand in 1992, the first nest found in Northern California. Elk Head Spring and Headwaters Forests
are contiguous at the head of the Elk River drainage.
Pacific Lumber owns 33 other stands of old-growth Redwood, scattered throughout
the company's ownership (see
Map). These stands range in size from 391 acres (Allen Creek) to 2 acres
(H-M0). Marbled Murrelets have been detected in some of these stands
but not others. To date "occupied behavior" has been seen on 21 of these other stands,
comprising 3,121 acres.
The analyses also consider the Marbled Murrelet population on other lands in the
area. Close to Pacific Lumber lands, the Humboldt Redwoods State Park holds significant old-growth
Redwood. The precise amount of old-growth and of Marbled Murrelet habitat on the
Park is unclear at this point. Murrelets do occur in at least some areas of the Park.
No other significant Murrelet population occurs near the bioregion.
Farther north in Humboldt county, a significant population is associated
with the Redwood National Park. Very few birds are regularly seen in Mendocino
County to the south. A small and isolated population also occurs in Santa
Cruz and San Mateo counties.
The US Fish and Wildlife Service, in designating Critical Habitat for the
Marbled Murrelet, delineated 36,000 acres on Pacific Lumber lands.
