CRATER LAKE NATIONAL PARK
Mazama Dorm Project
2000 Annual Report Summary
View Complete Report (PDF)
INTRODUCTION- The Corvallis Plant Materials
Center (PMC) entered into an amended agreement with Crater Lake National Park in
2000 to evaluate and increase grasses and sedges for revegetation purposes
(Mazama Dorm Project). It was agreed to maintain and harvest two grass and two
sedge fields and clean/process and provide the resulting seed to Crater Lake
National Park in September 2000.
ACCOMPLISHMENTS- Activities in 2000 included
maintenance and seed harvest of field increase plantings, maintenance of excess
containerized stock, establishment of seed increase fields, and delivery of
plant materials. A total of 10.9 kg clean seed was harvested from two grass and
two sedge plots. Although Carex spectabilis flowered in 2000, no seed set
occurred. All seed harvested in 2000 was provided to Crater Lake National Park
personnel on September 26, 2000. Excess containerized stock involved five
species and 140 containers. Two seed increase fields were established in fall
2000 in anticipation of seed needs for future restoration projects at Crater
Lake National Park.
TECHNOLOGY DEVELOPMENTS- Two new seed increase
fields (Elymus glaucus, 0.41 A; Bromus carinatus, 0.16 A) were
established via carbon banding on September 14, 2000. Prior to drilling, the
Bromus carinatus seed was treated with a systemic fungicide to control smut
and other seed borne fungal diseases. Diuron was applied immediately after
drilling to prevent weed seed emergence between rows. Both species established
well, and diuron provided excellent weed control.

THE 2000 CRATER LAKE NATIONAL PARK ANNUAL REPORT:
MAZAMA DORM PROJECT
I. Brief Background of Project
The Corvallis Plant Materials Center (PMC)
entered into an amended agreement with Crater Lake National Park in 2000 to
evaluate and increase grasses and sedges for revegetation purposes (Mazama Dorm
Project). It was agreed to maintain and harvest two grass and two sedge fields
and clean/process and provide the resulting seed to Crater Lake National Park in
Activities in 2000 included maintenance and seed
harvest of field increase plantings, maintenance of excess containerized stock,
establishment of seed increase fields, and delivery of plant materials. Details
are provided below.
II. Accessions Involved
Accessions included for Mazama Dorm are listed in
Table 1 (below). All of these accessions have been described in previous Annual
Reports; this report includes a summary listing along with the activities
conducted by PMC staff in 2000.

III. Field Seed Increase
Seed was harvested from established stands of
Elymus glaucus, Bromus carinatus, and Carex pachyastachya.
Although Carex spectabilis flowered in 2000, no seed set occurred. Seed
harvest and additional cultural notes are summarized in Table 2 (below):

2000 Field Seed Production Notes:
All grass and sedge species received three
applications of Tilt and Bravo fungicides in April/early May for rust control.
All plots were fertilized in September 1999 with 25 lbs/ac nitrogen (N), and in
February 2000 with 50 lbs/ac N plus 15 lbs/ac Sulfur (S). Weed control was
primarily performed by rototilling and swiping with Roundup between rows when
possible, spraying borders with Roundup, and hand-hoeing and roguing.
Broadleaf herbicides were applied in August
(2,4-D and Banvel) and again in October 2,4-D and Gallery) to control
broadleaves in the BRCA5 plot. Sedge plots were irrigated throughout the growing
season to improve seed yields. Grass and sedge fields were mowed, and the
residue was baled and/or removed as necessary following seed harvest.
Preemergent herbicides were applied between rows in sedge plots in October (Surflan)
and to the BRCA5 plot in October (Karmex).
Establishment of New Seed Increase Fields in
Two new seed increase fields of California brome
and blue wildrye were established on September 14, 2000 at the Corvallis PMC in
anticipation of seed needed for future restoration projects at Crater Lake
National Park (and future cooperative agreements between the PMC and the Park.)
Diuron (Karmex) was applied immediately after drilling to prevent weed seed
emergence between rows. Irrigation was provided as necessary during September
and October to promote establishment. Most seedlings emerged within 2-3 weeks
after planting, and stand establishment and vigor was rated as good/good for
both species. Overall, Karmex provided excellent weed control. Broadleaf
herbicides (2,4-D and Banvel) were applied in October to both new fields to
control the few broadleaves that were not controlled with Karmex. Details are
provided in Table 3 (below):

increase fields for Crater Lake National Park, at the Corvallis PMC in 2000
IV. Experimental Propagation
No experimental propagation trials were conducted
V. Container Plant Production
No container plant production was conducted in
2000, but excess containerized stock were maintained. This involved five species
(ACGL- 11 1-gal; LOIN5- 8 1-gal; VASC-16 1-gal; ERMA- 75 conetainers; and PERU-
30 4” pots).
VI. Delivery of Plant Materials
Seed provided to park personnel in September 2000
for the Mazama Dorm rehabilitation plantings is shown as Appendix I. All seed
lots were tested just prior to delivery (tests were completed by September 29,
2000) for percent viability and percent purity. The grass seed lots, blue
wildrye and California brome, exhibited 86 and 53 percent viability and 99 and
94 percent purity, respectively. The thick-headed sedge seed lot exhibited 82
percent viability and 99 percent purity.
