Sarah Walker

Forest Service botanist

Sarah Walker is a natural history writer who has lived along the Lewis and Clark trail in Idaho for the past 25 years. She writes a monthly nature column for the Moscow Community News (Moscow, ID) and articles for Bird Notes (Canyon Birders of Lewiston, ID), and served as editor for Sage Notes, newsletter of the Idaho Native Plant Society, from 1995-2000.

From 1986 to 2000 she worked on the Clearwater National Forest in Idaho as Lead Wilderness Ranger in the Selway-Bitterroot Wilderness, and before her retirement in 2002 she served as Forest Botanist.

As a wilderness ranger Sarah spent many years in the backcountry introducing visitors to the importance of light-on-the-land camping practices. In communities adjacent to the wilderness she taught local elementary students about low-impact camping skills, natural resource conservation, and American wilderness history.

Sarah received a BA in European History from Wheaton College in Massachusetts in 1969, and later studied Ecology and Life Sciences at the University of Montana. During her Forest Service career she received training in botany, silviculture, bryology, wetland ecology, and conservation education.

She joined the crew of writers for Discovering Lewis & Clark in the fall of 2003 as a contributor to “Today’s Bitterroot Mountains.”

    Cultivating Camas

    Invisible gardening

    Ethnobotonists and anthropologists describe the cultivation and storage of important food plants as complex systems capable of sustaining dependable annual supplies for large populations. The Nez Perce system for camas is a good example.

    Sheep in the Bitterroots

    A connection to 'Greensward Camp'

    by

    In 1924 a sheep “driveway” was cut through the forest from Musselshell to Superior, a distance of roughly 80 miles. The road-sized swath with its network of side trails was used for 20 years as a travel corridor for sheep. One spur accessed the site Lewis and Clark called “Greensward Camp.”

    There is a great abundance of a species of bear-grass which grows on every part of these mountains,” wrote Lewis on 15 June 1806. “It’s growth is luxouriant and continues green all winter but the horses will not eat it.”

    Modern invasives

    by

    During the summer of 2003 a weed inventory team from the University of Idaho searched the Lolo Motorway for weeds. They saw spotted knapweed four times, orange hawkweed twice, yellow hawkweed twice, henbane once, and goatweed 28 times: 37 widely-scattered weed sightings in about 50 miles.

    Winter’s Subnivean World

    Winter in the Bitterroots

    The same snow that deterred the Corps on both their crossings of K’useyneiskit provides the winter environment for those smaller animals who remain. Underneath the deep snowpack lies the subnivean (undersnow) world.
