place from June 16 to June 19, 2002 at the Selkirk College in
Castlegar, British Columbia. Watch for further announcements.
JUNIPER DUNES WILDERNESS AREA, FRANKLIN COUNTY, WASHINGTON
From: Joy Mastrogiuseppe [carex at moscow.com]
The Juniper Dunes Wilderness preserves the northernmost growth
of western juniper, _Juniperus occidentalis_ Hook. (Cupressa-
ceae), some of which have been around for 150 years.
One of Washington's botanical delights is Juniper Dunes, a large
system of sand dunes in southeastern Franklin County,
Washington, 10 miles north of Levey. The dunes, up to 130 ft.
tall, are surrounded by private lands developed for agriculture.
The U.S. Bureau of Land Management (BLM) has custody of about
17,000 acres of the dunes, in a checkerboard pattern with
privately-owned parcels. Much of the dunes area is stabilized,
but roughly 10 square miles hold more active dunes. Most of
these active areas are included in the ca. 7000 acres of the BLM
Juniper Dunes Wilderness.
The junipers of Juniper Dunes are western juniper, Juniperus
occidentalis, in its northernmost concentrated groves. Few,
scattered individuals grow further north, e.g. at the "Delight
Dunes" in Adams County, and a specimen of western juniper was
collected during the early 1900's at Wawawai, along the Snake
River in Whitman County. This tree, unfortunately, was growing
below the current water level of the Lower Granite reservoir.
The Juniper Dunes apparently represent a portion of the
shoreline of a huge ancient lake that occupied south-central
Washington, dating back to the Spokane Floods of the Pleis-
tocene. Ice dams across the Clarks Fork River in western Montana
broke during warmer periods of the Pleistocene, releasing enor-
mous volumes of water into eastern Washington-the Spokane Floods
that formed the channeled scablands. The lake was formed by
backwaters from Wallula Gap, which was too narrow to allow the
enormous volumes of water to pass. Layers of the fine silt
deposited can be seen in the sand, and these constitute a suffi-
cient moisture reservoir to support the growth of junipers.
The general vegetation of the Juniper Dunes is typical of very
sandy Columbia Basin habitats: a mixture of the big sagebrush-
needle and thread habitat type (HT) (_Artemisia tridentata-Stipa
comata_ HT) and the bitterbrush-needle and thread HT (_Purshia
tridentata-Stipa comata_ HT) (Daubenmire 1970). There are strong
components of rubber rabbitbrush (_Chrysothamnus nauseosus_) and
green rabbitbrush (_C. visicidiflorus_). Stands of bluebunch
wheatgrass (_Pseudoroegneria spicata_), and Indian ricegrass
(_Achnatherum hymenoides_ subsp. _hymenoides_), are scattered.
Forbs here that are typical of very sandy habitats are white
sandverbena (_Abronia mellifera_), Franklin sandwort (_Arenaria
franklinii_), sicklepod milkvetch (_Astragalus sclerocarpus_),
turpentine cymopterus (_Cymopterus terebinthinus_), hymenopappus
(_Hymenopappus filifolius_ var. _filifolius_), prickly-
largespine pear cactus (_Opuntia erinacea_), sand-dune penstemon
(_Penstemon acuminatus_), lanceleaf breadroot (_Psoralea
lanceolata_), and sand dock (_Rumex venosus_). Other forbs
include Carey balsamroot (_Balsamorhiza careyana_), wild-
hyacinth (_Brodiaea douglasii_), larkspur (_Delphinium
nuttallianum_), wild flax (_Linum perenne_), snow buckwheat
(_Eriogonum niveum_), desertparsley Indian-potato (_Lomatium
macrocarpum_), and silverleaf phacelia (_Phacelia hastata_).
Access to the Juniper Dunes Wilderness is limited. Because the
wilderness is surrounded by private lands, there is currently no
strictly legal access. Private landowners often allow access
through their lands, but potential visitors must contact the BLM
Spokane office for permits (phone 509-456-2570).

NIPSON ANOMEMATA ME MONAN OPSIN
The ancient Greeks often put this palindrome on fountains. It
translates as "Wash the sin as well as the face." A good sugges-
tion for all of us, sinners and nonsinners, as we begin the
palindromic year 2002. In this special year, I would like to
wish you all good luck, lots of happiness and success in your
life and work.
With passing of the old year, I would like to thank to all of
you who contributed to BEN with your notes and articles and
shared your experience with other BEN readers. BEN would not be
possible without your help. To all of you who always wanted to
submit something for BEN, I wish you the courage and fortitude
to sit down and bang off a few paragraphs on the keyboard and
send it to me. I would be delighted to have your contributions!
The Victoria Telecommunity Network has continued to be a reli-
able host of our mailing system, Scott Russell has been a faith-
ful web master, and Jan Kirkby and others have kept untangling
my English into a (more) readable form. Many thanks to all of
Enjoy this coming palindromic year--the next one will not come
