PROPOSAL
PITKIN COUNTY ON CALL ECOLOGICAL SERVICES
CONTRACT #008.2019
A-31 2021 SKY MOUNTAIN PARK SAGEBRUSH TEST PLOT IMPLEMENTATION
1.0 SUMMARY
In early 2020, the Pitkin County On Call ecological team in partnership with PItkin County Open Space
and Trails (OST) developed a test plot design for sagebrush restoration at Sky Mountain Park. This
proposal is to provide consultation and support to implement the test plots, monitor their success and
provide recommendations to restore the degraded pasture at Sky Mountain Park. The overall goal is to
develop a successful restoration strategy specifically tailored to the current OST desires that can be
applied to other open space properties where sagebrush restoration is a goal.
2.0 BASIS OF NEED
In January 2018 the Concept Restoration Plan, Hayfield, Sky Mountain Park was developed by Western
Ecological Resource, Inc. The Plan outlines steps needed to restore an approximate 9-acre agricultural
hayfield to a native sagebrush shrubland including conceptual level plans for irrigation. Briefly, the plan
called for mowing the non-native hayfield and applying glyphosate (i.e. RoundUp) herbicide to kill the
grass several times throughout the growing season. Next the site was to be seeded with sagebrush and
other native herbaceous grasses and forbs using a no-till drill. However, OST indicated that they would
prefer not to utilize a broad-spectrum herbicide such as glyphosate (which kills all vegetation) on such
a large area due to environmental concerns.
Over the 2019/2020 winter, the Ecological On-Call team and OST developed a design for sagebrush
restoration test plots. The test plot designs are based on extensive research, literature reviews and
analysis for feasibility and scalability. We will investigate three seeding/planting methods across 12 test
plots, with and without irrigation and fencing, to restore sagebrush shrublands and determine the most
effective restoration methods that are acceptable to OST. Test plots will include the following
treatments:
●Mowing and Drill Seeding (Irrigated and non-irrigated, fenced and unfenced)
●Tilling and Drill Seeding (Irrigated and non-irrigated, fenced and unfenced)
●Fabric Mulch and Containerized Planting (Irrigated and non-irrigated, fenced, and unfenced)
In addition, we will conduct a fourth method, outside of plots, which involves harvesting and placing
sagebrush shrub “carcasses”.
●Sagebrush (Carcass) Installation- 10 Total (Non-irrigated)
In the summer of 2020, the test plots were laid out and mowing and tilling commenced under Task
Order A-18. However, the appropriate amount of native seed was not able to be collected due to a poor
seed set. We have assumed any seed collection or carcass installation in fall of 2021 would be
coordinated directly by OST staff.

3.0 APPROACH
TASK 3. SEEDING OVERSIGHT - FALL 2021
DHM will take lead on drill seeding supervision and coordination with a contractor, including seed mix
verification, means and methods for sagebrush only as well as sagebrush and native mix, straw wattle
installment around 4 of the 12 plots, as spec'd in plans, etc. to ensure drill seeding success.
TASK 4. TEST PLOT SAGEBRUSH PLANTING OVERSIGHT - FALL 2021
PeakEco would take the lead on coordinating a team to install the 408 sagebrush plugs, based on an
estimated density of 1 plug per ~50 square feet (plants will be placed 7 ft on-center as specified in the
plans) in 4 plots each 40 ft x 120 ft in size. After installation, landscape fabric will need to be laid down
in order to reduce competition for weeds and grasses and irrigation set up to water 2 of the plots.
Landscape fabric is to be cut into 2 ft x 2ft squares and centered on each plant. The costs in the attached
spreadsheets are broad estimates only and may change depending on level of involvement by OST staff.
The cost does NOT include materials or procurement of the materials. We suggest that the fabric mulch
squares (biodegradable and nonbiodegradable) be cut (using a template) well ahead of time. We also
suggest that OST staff receive the sagebrush plugs ahead of time and hardened off (if need be) prior to
the plant day. Planting should occur in the fall two weeks before the first killing frost.
TASK 5. QUANTITATIVE MONITORING AND REPORTING - 2022
This task describes the annual quantitative monitoring and reporting of the test plots that would be
conducted after the project is fully implemented. During the summer of 2022, PeakEco will
quantitatively evaluate the success of the different treatment methods and write up the results in an
annual monitoring report. Quantitative methods may include a combination of standard OST point-
intercept protocol for vegetative cover and species density as well as a straightforward count of plug
survivorship. The report will also include a comprehensive write-up of the seeding and planting
methodology, graphics illustrating the plot layouts, year to year photographs from fixed points, and
recommendations for continued success.
TASK 6. QUANTITATIVE MONITORING & DATA ENTRY - 2023 & 2024
This task includes the annual quantitative monitoring of sagebrush plots to be conducted in 2023 and
2024, the second and third growing seasons after seeding and planting. The quantitative monitoring
would be conducted in September by Rea Orthner along with two field technicians to be provided by
Pitkin County OST. The field techs will be responsible for locating the sagebrush plugs, measuring the
height and width, and recording the data on a sheet to be provided by PeakEco. Likewise, in the seeded
plots, the field techs will identify the tagged sagebrush shrubs or any new plants and take height and
width measurements. Rea Orthner will train the field techs on data collection. In addition, Ms. Orthner
will evaluate the overall success of the seed mixes and take a quick inventory of all species present
within each of the plots in efforts to determine the efficacy of the seed mixes applied. No line-point
intercept vegetation sampling would be conducted until the end of Year 4 or later. At the end of the
field season, the data will be entered into the master data spreadsheet by the OST field techs, verified
by Rea Orthner, and then uploaded to the data portal. Finally, Ms. Orthner will update the Year 1 report
with data collected in Year 2 and 3. This task also includes a few quick 1-2 hour site visits to review
progress during June, July, and/or August when Ms. Orthner is in the area on other projects.

4.0 EXPECTED RESULTS, DELIVERABLES & COLLABORATION
In 2021, the deliverables include email coordination for the sagebrush seeding (oversight by DHM) and
for sagebrush test plug (oversight by PeakEco). In addition, PeakEco will create a brief memo
documenting the work completed in 2021, including copies of seed tags, type of drill seeder used and
seed disbursement in drill boxes, number and layout of sagebrush test plugs, type of mulch squares and
other details as necessary to evaluate success in future years.
Please note that all irrigation and fencing implementation support tasks for this project are
encompassed in Task Order A-17: Brush Creek Pond Restoration.
In 2022, PeakEco will write an Annual Monitoring Report as detailed above in Task 5. In 2023 and 2024,
we will update the monitoring report to include additional data collected in those years.
5.0 TIMELINE
OST Staff will continue the mowing and tilling protocol previously established throughout the spring
and summer and early fall. Ideally planting of plugs should occur two weeks prior to the first killing frost
and seeding should occur in late fall, before soils are frozen. Per the Sagebrush Test Plot Design graphic
(dated 6/3/2020):
● Sagebrush seeds are programmed to germinate in very early spring, soon after dispersal in
the late fall or winter. Snow cover is essential for seeding success, whether the snowfalls
before or after the seeding. The seeds can even germinate beneath the snow and be ready for
action in very early spring right after snowmelt
● Seeding earlier in the fall places the sagebrush seed at risk for a longer period prior to
germination and could potentially cause premature fall germination, which would likely result
in winterkill.
● Spring seedings are almost universally unsuccessful because the soil dries too rapidly for ‘the
tiny seedlings to get their roots established.
