Noxious Weed Management Plan
1. Introduction
The Colorado Noxious Weed Act (C.R.S. Title 35, Article 5.5) declares that certain undesirable
plants constitute a threat to the "continuous economic and environmental value of lands of the
state" and requires that these "noxious weeds" be managed on private and public lands. The Act
further declares that control of noxious weeds should use methods that are least damaging to the
environment but also practicable and economically reasonable. Ursa Operating Company, LLC
(Ursa) started operations in the Piceance on April 1, 2013 and will be responsible for management
of noxious and undesirable species identified on land leased associated with these assets. The local
government(s) management of noxious weeds for Ursa assets (known as Battlement Mesa), is
Garfield County which requires that land owners or persons or entities leasing the land within the
county manage noxious weed infestations on their respective land.
By implementing a Noxious Weed Management Program, adverse economic and environmental
impacts will be minimized for Ursa and surrounding stakeholders. Maintaining control of noxious
weed populations within Ursa assets is important to keep the cost of noxious weed abatement,
stormwater, and revegetation to a minimum. Since the three (3) elements are intertwined;
improvement in one (1) area will facilitate improvements in the other areas of concern. It is also
vital that the expansion of noxious weeds from Ursa assets to private land not associated with oil
and gas exploration is monitored closely to ensure weed abatement measures are effective. For the
most successful management of noxious weeds, regular communication between Ursa and
property owners with adjacent land should be developed.
This plan is intended to provide Ursa with a noxious weed management outline for the area of
concern — in this instance, the asset known as Battlement Mesa. The objectives of the plan include:
providing basic environmental information about the sites, locating and mapping of noxious weed
populations, outlining and evaluating possible treatment methods, and establishing preventative
measures to minimize noxious weed expansion. This plan will also provide an amendable
document for current and future Ursa land managers.
2. Site Characterization
Ursa assets covered under this plan are located in Garfield County in western Colorado (refer to
Figure 1 for a map and Appendix A for listed locations). The assets can be found using the Public
Land Survey System (PLSS) in Appendix A or by reviewing the map in Figure 1.
The vegetative communities that characterize these sites include: sagebrush, rubber Rabbitbrush,
snakeweed, Gambel oak, bunch grasses and pinyon juniper. This highland is characterized by
moderate moisture levels, moderate temperatures and a moderate growing season. Snow is
typically present on site from mid-November to late -March, with an average of 80-90 frost days
per year. The soil type varies across assets. For more information on soil type, refer to Appendix
B and Figure 2.
The potential treatment area with regards to noxious and undesirable species will include
appropriate and applicable pads, right of ways (ROWs) including access roads and pipeline ROWs,
topsoil stockpile if applicable, and land surrounding the Ursa assets that has been disturbed by
related Ursa activity.

Noxious Weed Management Plan 1
3. Weeds of Concern
To meet the requirements of the Colorado Noxious Weed Act (ACT), the operator shall conduct
prescribed management techniques for noxious weeds control and prevention. Species warranting
prescribed management control and prevention are included within the Colorado Noxious Weed
Lists: List A — designated for statewide eradication; List B — managed to prevent further spread
and, for selected species, designated for eradication in large areas; and List C — of more localized
concern, but for which the State will provide education, research, and biological control assistance
to jurisdictions that choose to manage the species. The complete Colorado Noxious Weed List can
be found in Appendix C. In addition to the state wide weed list, individual counties have their
own noxious weed lists. The county lists are comprised of noxious weeds from the state list that
are more specific to the area of concern.
Garfield County has designated twenty (21) of the seventy four (74) species from the Colorado
Noxious Weed List to be likely species found in the vicinity of their jurisdiction. Appendix D
contains the Garfield County Weed List, and specific details can be acquired through the Garfield
County Noxious Weed Management Plan available online.
4. Weed Inventory
Noxious weed surveys are conducted on Ursa assets prior to any earth disturbing activities. Please
refer to Garfield County Impact Analysis for the BMC D well pad location for the weed survey.
Additional surveys will be conducted annually by qualified individuals to ensure noxious weed
treatments and noxious weed populations. Populations of noxious weed infestations will be
mapped by qualified individuals using global positioning units (GPS) units. The Noxious Weed
Inventory Form, Appendix F, can be used to provide supplemental survey information if the
surveyor deems it appropriate. The surveys will provide a way to identify new noxious weed
populations as well as an assessment tool for previously treated populations. The inventory is to
be updated as the surveys are performed. There will be an annual review to assess the overall
noxious weed populations and success of treatments applied.
5. Treatment Methods
The treatment methods and descriptions listed below were obtained from the Mesa County
Noxious Weed Management Plan (Mesa County, 2009). Management techniques include
preventative, cultural, physical/mechanical methods, biological and chemical approaches. Optimal
noxious weed management methods will vary with the environmental variables of the area of
interest. Soil type and stability, grade, moisture regimes, growing season, pre-existing noxious
weed populations, land use, water availability, weed type and stage of growth as well as the
intensity of the infestations should all be taken into account when preparing a noxious weed
management plan.
The management methods should have minimal impact on the environment and be economically
fitting for the Operator in charge of implementing the noxious weed management program. When
assessing weed management on a property, it is important to evaluate possible modes of
transportation for the noxious species. Areas to take into account include; waterways, roads, game
trails, areas with livestock and equipment storage sites to name a few possibilities. The
Ursa Operating Company Battlement Mesa PUD
Noxious Weed Management Plan 2
transportation of noxious species is a problem shared by all the stakeholders in the affected area.
Good communication should be established between the affected parties for proper management
of the noxious weed populations. Most management plans utilize a combination of the treatments
outlined below.
5.1 Preventative Methods
Preventative methods include practices involving good land stewardship. These practices
include, but are not limited to; using weed free certified products, erosion control
measures, and regularly cleaning equipment.
5.2 Cultural Methods
Cultural methods facilitate competition from desirable plants through actions such as;
dense seeding, irrigation, carefully monitored grazing practices and fertilization.
5.3 Physical and Mechanical Methods
Physical and mechanical methods include mowing, disking, hand removal, plowing,
burning and solarization. The goal of these methods is predominantly to prevent seed
production. Roots should be severed at least two (2) inches below the soils surface for
optimal control.
5.4 Biological Control Methods
Biological control methods involve the introduction of living organisms that are deleterious
to the noxious weed species. This method is only applicable for infestations larger than five
(5) acres in size, and rarely provides complete control of the noxious species. Frequent
monitoring must be carried out with this method.
5.5 Chemical Control
Chemical control can offer the most effective means of noxious weed control when applied
at the appropriate time. Not all herbicides are equally effective against all weeds, nor can
every herbicide be used in all settings. The respective herbicide applicator should consult
with a weed manual before applying any herbicide to the land.
6. Treatment Recommendations
6.1 Pad Surfaces
It is recommended that the area directly adjacent to structures be treated with a bare ground
herbicide. The bare ground treatment will be applied once a year or as needed to a ten (10)
foot perimeter around the structures located on Ursa developments. All other areas are to
be spot treated with an appropriate herbicide.
6.2 ROWs and Surrounding Lands
Ursa assets should be treated with a selective herbicide appropriate for the species where
the noxious weed is found. The appropriate chemical to be applied will be determined by
the licensed herbicide applicator. The specific herbicide applied will vary depending on the
landowner, time of year and the stage of growth the plant has obtained at the proposed
Ursa Operating Company Battlement Mesa PUD
Noxious Weed Management Plan 3
treatment date. The Bureau of Land Management (BLM) must be contacted prior to
treatment on Federal lands.
6.3 Special Requirements
At this point in time there are not any special requirements for Ursa assets or the associated
ROWs with regards to management of noxious weeds or other undesirable species. Any
and all special requirements will be amended to the document as soon as practicable.
7. Management Strategies
7.1 Prevention
Taking preventative measures to abate the spread of noxious weeds is critical for proper
land management. Noxious weeds can become established on or near disturbed land very
rapidly and have the capacity, capability and potential to spread quickly to other areas.
Noxious weed seeds and vegetative matter can be transported by means of animals,
vehicles, shoes, and hay to name a few examples of transportation. Operators should be
aware of established noxious weed populations and the possible transport mechanisms on
their property and surrounding properties.
7.2 Revegetation and Rehabilitation
After an area has been successfully eradicated of noxious species, or before establishment
has taken place, actions to revegetate the disturbed area should be taken to minimize the
chance of noxious weed establishment. If the disturbed land has desired species growing
as a result of revegetation efforts, competition with noxious species will be increased.
Therefore, the potential and capability of the noxious weed to establish in the disturbed
area is limited.
Noxious weed management strategies for Ursa will include a monitoring program. Surveys
will be carried out between the months of April and October. Noxious weed populations
will be monitored at this point through qualitative visual interpretation as well as mapping.
8. Conclusion
This noxious weed management plan provides an outline for the treatment and management of
noxious weeds. Please refer to Appendix G for the Noxious Weed Summary Documents which
provide contact information as well as general information pertaining to Ursa assets. An annual
report will be compiled to assess the overall management program.
Noxious weed control is critical to guarantee the environment is preserved for future generations
to enjoy and utilize. Adhering to this management guide will aid Ursa in managing noxious weeds
encountered during active involvement at developed sites.
These recommendations are not intended to be used as a definitive guide for noxious weed
management. Herbicide recommendations are available from both the state and local governments
and/or licensed applicators.
