BOARD OF COUNTY COMMISSIONERS
PASS-AROUND REVIEW/WORK SESSION REQUEST
RE: Colorado Department of Agriculture Grant Opportunity
DEPARTMENT: Public Works, Weed Division DATE: January 27, 2014
PERSON REQUESTING: Tina Booton, Weed Division Supervisor
Brief description of the problem/issue:
The Colorado Department of Agriculture is offering grant funding to help address List B eradication species.
These species for Weld County include: spotted knapweed, absinth wormwood, Houndstongue, diffuse
knapweed and Dalmatian toadflax (listed in order of infestation acres) all north of Highway 14. To achieve the
goal for eradication, additional staff is needed to make contact with the landowners and to follow-up with the
work done by the landowners.
This grant would fund one (1), four (4) month seasonal position to map these species, contact the landowners,
offer cost-share for the treatments and help treat the spotted knapweed. The spotted knapweed is the smallest
infestation we have and therefore the species of greatest concern. The grant would also purchase a
GPS/mapping unit to assist with the requirements.
The total grant request would be for $13,000 from the Colorado Department of Agriculture. The budget
breakdown is $11,000 for staff and $1,200 for an iPad and software.
The proposed match is: $5,850 in-kind from the Weed Division Budget and $16,000 from Colorado State Land
Board, CDOT, Pawnee National Grassland, West Greeley Conservation District and other eradication weed
specific cost-share programs. This gives a total grant match of$ 21,850. Since the county match is in-kind,
there is no cost to the county for this grant application.
It is acceptable by the Colorado Department of Agriculture for Tina to electronically sign the grant application.
All applications have to be submitted via email. The grant application is due February 14, 2014.
What options exist for the Board? (Include consequences, impacts, costs, etc. of options)
1. Put the application on the BOCC agenda prior to February deadline and allow Tina to submit the grant
proposal and electronically sign the application.
2. Do not submit the grant proposal.
Recommendation:
1. Place application on BOCC agenda prior to February 14th grant deadline and allow Tina to submit and
electronically sign the grant application.

Brief Description This project would hire one seasonal staff member to work with landowners. including mapping and
of Project treatment of List B eradication species in northern Weld County. These species include spotted
(one paragraph synopsis knapweed. absinth wormwood, houndstongue. diffuse knapweed and Dalmatian toadflax. The grant
of the abstract) would also purchase a mapping unit to assist with this project as well as provide enhanced data to the
Colorado Department of Agriculture weed mapping program. The new mapping would provide a better
idea of the progress that is being made on the diffuse knapweed and Dalmatian toadflax. As well as
allow for follow-up to verify the complete eradication of spotted knapweed. absinth wormwood and
houndstongue.

Project Evaluation Criteria
The fields below will expand to fit the amount of text entered. However you must tab (or click) out of the box for it to expand and
fully display the text entered.
1. Describe the background of the project, including the history of the infestation/s. This history should include: when found,
treatment/s to date, state weed funds used thus far, other funds used (private, local, other state, federal). A map or maps
showing the perimeters of populations and locations of significant hotspots should be included as attachments to the
application.
Weld County has taken an active role in addressing noxious weeds as much as possible with budget and season constraints.
Landowner education about noxious weeds has always been a high priority. Weld County has always worked to find assistance
for landowners to help with the treatment of noxious weeds.
Dalmatian toadflax, absinth wormwood and houndstongue were reported in Donald Hazlett's Vascular Plant Species of the
Pawnee National Grassland. This report was published in September 1998. Around this same time a landowner brought
Dalmatian toadflax growing on their CRP ground to the attention of Ron Broda, the Weed and Pest Supervisor at the time.
Since the late 1990's Dalmatian toadflax has been addressed periodically using Colorado State Land Board funds. In the early
2000's the goal was landowner education and awareness of the Dalmatian toadflax. Around 2003 chemical treatments were
started. These treatments included the use of Tordon 22K. The county roadsides were heavily targeted along with using a
helicopter to treat some of the northern draws. Sporadic chemical treatments went on in the general area until 2006 when the
first attempt to thoroughly map the infestation was made. A follow-up mapping event was completed in 2012. Chemical
treatments have been made sporadically in the area by concerned landowners through 2013.
Treatment of houndstongue started in 2007 after it was identified in the 2006 mapping with the Dalmatian toadflax. This species
has been eradicated from the county road system through the use of chemicals and some hand pulling. It has been brought to
the attention of landowners who have slowly been addressing the infestations on their property. Houndstongue was identified
when the infestation was still very small in terms of acres. In 2014 we are very close to having this species eradicated. Total
known acres of Houndstongue in all of Weld County is less than four acres.
Control efforts for absinth wormwood started in 2005 with a state weed fund grant. Absinth wormwood is growing along Willow
Creek. Pawnee National Grassland has made consistent treatments for this species on their properties and have nearly
eradicated it. The limitations have been an out of state private landowner who saw nothing wrong with the plant; and the rest of
the infestation is on state lands and private management in the middle of sections not readily accessible or easily viewed. Up
through 2013 most of the properties infested had started implementing chemical treatments to address the absinth wormwood.
In 2012 the hold out landowner made his first chemical treatment which resulted in a great reduction of the infestation on the
land.
In 2006 and 2007 the diffuse knapweed infestation in northern Weld County was identified because of landowners who cared
about this "plant taking over" . The local landowners insist that diffuse knapweed came in as a seed contaminate with the CRP
plantings years ago. In 2008 a High Plains Invasives Project grant was secured to start helping landowners address this
species. This same grant was secured in 2009 and 2010. Great progress was made toward the eradication of this species
during these three years. From 2011 through 2013 steady work has continued on this species on private lands. However, the
momentum has slowed down. Weld County has nearly eradicated the diffuse knapweed on the county roadsides. Only
occasionally does a plant show up.
Diffuse knapweed is also infesting the neighboring lands to the north of Weld County in Nebraska. Several meeting with various
government officials in Nebraska have occurred. Nebraska is trying to address this species as well as Weld County.
Compliance with landowners at the border is improving. This partnership is newer in its establishment and is evolving as
progress is made to reach eradication status of diffuse knapweed in this part of Weld County.
Spotted knapweed was identified at the end of 2010 growing season, during the last year of the High Plains Invasives Project.
The summer of 2010 had been a wet spring. It was only identified on one parcel along with some diffuse knapweed. No
additional work has been done on this situation to date due to the lack of staff availability.
2. Describe the importance of the project (locally, regionally,state-wide) and why it should be considered a high priority for
funding.
The targeted species can be eradicated with a little more effort. Weld County is the third largest county in the state. Weld
County also borders two other states, Wyoming and Nebraska. By eradicating these weed populations. we can prevent the
spread to another state as well as our neighboring counties.
3. Describe the management goals for the targeted List B species that are subject to elimination in the county/counties
affected by this project. Please include your long-term plans,timeline for elimination based on past and potential results,
measureable milestones used to evaluate your progress towards elimination (for example, 25% population reduction by next
year, 50%in the following, and elimination 3 years from now), and future efforts beyond the scope of this grant period.
The management goals for the List B species is eradication in three to five years from today. What has been noticed in previous
years is that with dedicated focus and attention the private landowners will address the noxious weeds. Without this attention,
the weeds tend to take a back seat to the necessity of their continued control. An additional obstacle with this project is the
number of out of county and/or state landowners that own these parcels infested with noxious weeds. It takes extra work to
convince these landowners of the infestations on their property and the need to control something they can not readily visit
themselves. With this project a dedicated seasonal staff member will be hired to focus on these eradication species in northern
Weld County and address these special situations. The plan is to then build this position back into the regular budget for 2015 to
continue this work until full eradication of all species is achieved.
Spotted knapweed has a long-term goal to reach eradication by 2018. In 2014 this species infestation will be thoroughly
mapped. All populations will be treated before the plant goes to seed set. This will address 90 to 100% of the plants growing
and prevent new seed from being formed. Then from 2015 through 2018, the mapped sites and surrounding areas will be
monitored to verify that no additional seed has germinated. If any plants are identified, they will be treated accordingly with
either hand pulling or chemical treatment.
Absinth wormwood treatments through 2013 have successfully reduced the original stand by 50% and up to 100% in some
areas that have been treated on a regular basis for several years. With a staff member who can focus on this species
eradication by 2018 is possible. The goal would be to reduce the existing population by 50% each year from 2014 through 2016;
then there would be two years of monitoring to verify that no additional plants develop.
From 2008 to 2013 houndstongue has been reduced to less than four acres. It has been eradicated from the county roadsides
and only exists in a few drainage areas that occasionally have water. These are also areas where the cattle tend to hang out.
With a focused effort this species should easily be eradicated from the private and state lands by 2018. In 2014. 100% of the
existing plants will be pulled or sprayed depending on stage of growth when found. From 2015 through 2018 monitoring will be
done to address any seeds that germinate in the existing surrounding areas where the species once was.
Diffuse knapweed is a species we have been working toward eradicating since 2008. For those first three years, under the High
Plains Invasives Project when staff was able to focus on this species, the population was reduced by 25%. Since then Weld
County has been able to eradicate the species from the county roadsides. Therefore, it is possible to make good strides on this
species. The goal for 2014 will be to build the landowner motivation to reduce the existing population by 25%: then each year
afterward reduce the population by at least 25% until we reach eradication by 2020.
Overall the goal is to eradicate Dalmatian toadflax west and east of Highway 85 and south of county road 138 on the east side
and south of county road 126 on the west side. The populations north of these roads will be suppressed with the eradcation
goal targeted for a later date. The southern area should be eradicated by 2020. The northern area should be eradicated by
2035 at the latest. In 2014 the southern part of the infestation will be reduced by 20%. Each year afterward a 20 to 25%
reduction will be achieved. This should provide eradication by 2020 for this lower area. The northern area is largely owned by
six landowners/land managers. Weld County will work with these landowners to focus on suppression until the goal for
eradication can be achieved.
4. Describe your integrated weed management strategy for this project. Specifically, what two or more major management
techniques will be employed and how are they expected to interact to enhance the treatment of targeted species? (Examples
of IWM strategies: community weed-pull, competitive seeding, decontamination areas).
The integrated weed management strategies that will be implemented with this project include weed pulling of the spotted
knapweed and houndstongue. Spotted knapweed and houndstongue are biennial species. They will respond well to pulling.
This will allow the spotted knapweed and houndstongue to be addressed before seed set and yet while it can still be positively
identified. If infestations are positively identified at a correct timing for chemical treatments. then these will be utilized.
The other eradication species will be chemically treated at the appropriate growth stage to reach the eradication goal. Chemical
treatments provide better control of the perennial weeds by addressing the root growth. Chemical treatments are also more
effective on the large acreage infestations that the other species present.
Reseeding will be used if an area has limited native plant competition. The goal is to have a good amount of positive, native
competition so that the noxious weeds do not return. Typically this will be accomplished with seeding native grasses.
Occasionally, forbs might be utilized if the site is best reclaimed with the addition of native broadleaved and shrub plants.
Biological control will be investigated for use on the northern most Dalmatian toadflax infestations. These infestations occur in
steep draws and large patches, where biological control might be a viable option for reducing the Dalmatian toadflax population
and suppressing it. While the lower infestations are being eradicated with the use of chemical treatments.
5. Describe what you think the likelihood to be of re-infestation by the targeted species or other invasive/noxious species in
future years. Describe the possible causes of re-infestation, and most importantly, what actions can be taken to reduce this
possibility?
Most of these infestations are located in fairly healthy native plant communities. There are lots of grasses and native wildflowers
in nearby settings. If noxious weeds can be eradicated from these settings the native plants should fill in. This will prevent
reintroduction of these or other species from establishing themselves. However, if some of the populations are growing in
heavily disturbed sites, then reseeding efforts will provide assistance to prevent the re-infestation of the noxious weeds and
other non-native plants.
6. Describe the education or community involvement functions of your project, what it entails, and what outcomes you expect
to achieve.
The educational components of this grant include providing fact sheets to landowners. These fact sheets with color pictures and
chemical options have already been created for each of the five noxious weed species.
Additionally, there will be an article in the West Greeley Conservation District (WGCD) newsletter that identifies the List B
eradication weed species covered in this grant, biology of these noxious weeds, eradication options and the overall goals of this
grant along with contact information. This newsletter is mailed to 11,200 residents. The project area covers a good percentage
of the WGCD area.
An announcement of the grant project will be made on the Weld County's FaceBook page. As the summer progresses, follow-
up postings about the specific weed species, pictures and any other relevant information will also be passed on this way.
From these broad educational pieces, the goal is to have residents of Weld County made aware of these noxious weeds. The
residents of Weld County will be additional eyes looking for the noxious weeds in the County and telling their neighbors about
the negative impacts these weeds, once established, can have on their lands and livelihood.
The seasonal staff member will also reach out to the landowners in each of the areas with the noxious weeds. The staff member
will draft a letter for the specific weed species of concern. These letters will be mailed out and/or emailed to all of the identified
landowners in each of the areas.
The seasonal staff member will follow the letter with phone calls to the landowners that we have contacted and anyone who
calls in. Private meetings will be set to discuss the efforts being made by the landowners and what they plan to do in 2014 to
address these eradication species. The staff member will be able to help the landowner make changes to their program to make
it more successful, if needed. These meetings will provide specific education on the weeds. how best to eradicate the species,
offer cost-share money to assist in these efforts. The staff member will also get permission to map the noxious weed
infestations at these meetings so that there is a clear understanding of the progress being made.
If after speaking with some of the landowners,they want to have a "town hall" meeting to discuss these species as a group, this
will be arranged. If these meetings are held, both the seasonal staff member and Tina Booton, the Weed Division Supervisor,
will conduct these meetings.
The letters and one-on-one meetings will be the "push"that a number of the landowners need to get them to address the
noxious weeds. It brings the requirements back in front of them and makes noxious weed control a priority in their schedule.
Therefore, from these attempts, the landowners will start treating their infestations and taking the situation seriously. Weed
control needs to be on the front burner for them and the best way to do this is to have a staff member that can follow up with
landowners showing them the importance to eradicate these species.
7. Describe any partnership(s)that exist for this project, including the responsibilities and contributions of each partner. Do
you have assurances from project participants that they are committed,formally or informally,to sustaining noxious weed
control efforts on the lands they own or manage? Please include how long the partnership(s) have existed, and describe their
value to you in terms of achieving your management goals. (If this is a single-applicant project,type N/A.)
These are long standing partnerships in this project. We have worked together over the years on various projects to address
weed concerns. These partnerships have been evolving since the late 1990's. The assurances from the partners are both
formally and informally made.
Without these partnerships it would not be possible to help the landowners of Weld County as much as is done, by acquiring
grant funds as well as other educational opportunities. Not only are these entities a financial partner, they also provide the
Weed Division with information and serve as another set of eyes on the land.
For this project the partnership breaks down as follows:
CDOT: $2500 cash for the Weld County Weed Division to spray Highway 85 from Nunn to WY.
Pawnee National Grassland: $500 in-kind for them to treat and monitor their own lands for absinth wormwood, diffuse
knapweed and Dalmatian toadflax.
West Greeley Conservation District: $6100 in-kind to print and mail one issue of their newsletter promoting the project and
providing education about the noxious weeds of concern.
Colorado State Land Board. $4853 cash to cost-share with landowners for Dalmatian toadflax eradication in 2014.
Weld County Government: $5350 in-kind to implement and carry out the grant activities.
Weld County Government: $8500 cash to cost-share with landowners on the eradication of diffuse knapweed and absinth
wormwood.
8. Is this the first time you've applied for state weed funds as an organization, or for your county or jurisdiction? Please
describe your start-up goals and funding needs (short-term, including this grant application, and longer-term needs as well). (If
this is an established program or partnership,type N/A.)
N/A
9. Summarize specific quantifiable and measurable project objectives/activities proposed for this grant period.These should
be measurable objectives that can be used to evaluate your project's effectiveness at the end of the grant. (Example: We will
complete 2 rounds of herbicide treatment (spring and fall) on all targeted weed species between June and September.)
1. All infestations of spotted knapweed will be mapped between May and June.
2. All infestations of spotted knapweed will be sprayed or pulled by the end of August.
3. All landowners will treat the absinth wormwood on the lands in their control by the end of June. before seed set.
4. Infestations of houndstongue will be mapped between May and September.
9 PP P
5.All infestations of houndstongue will be sprayed or pulled by the end of August.
6. The diffuse knapweed map will be updated. This will be completed by the end of September.
7. Landowners with diffuse knapweed will be worked with to have their infestations treated. At least 10 of the landowners will
chemically treat their diffuse knapweed infestations by the end of September.
8. The data from the 2012 mapping of Dalmatian toadflax will be retrieved and incorporated into a map with the 2006 data for
ease of comparing progress being made.
9. Landowners with Dalmatian toadflax will treat their infestations by either spraying or pulling the plants. By the end of
September at least 15 landowners will have addressed their infestations.
10. Weld County will complete 2 rounds of herbicide treatments on all targeted weed species along the county roads between
May and October.

List B Eradication Species in Northern Weld County
This project is focused in the northern part of Weld County. It covers four distinct zones in this part
of Weld County. See the project maps for exact areas. The project would provide the staff hours to focus on
meeting the eradication requirements that has been set for five list B weed species. These species are spotted
knapweed, houndstongue,absinth wormwood,diffuse knapweed and Dalmatian toadflax. The project would
also provide the much needed newer mapping unit. The better data collected with the new unit will be used
to make additional plans for control efforts, track the progress being made toward eradication as well as be
supplied to the Colorado Department of Agriculture yearly.
Since 2000 control efforts and attention have been given to various areas in the overall project region.
The focus for eradication started with Dalmatian toadflax throughout the 2000's. In 2005 absinth wormwood
eradication became a priority. In 2006 focus on eradicating houndstongue was added to the list of priorities.
Finally in 2007 diffuse knapweed was added to the list of eradication species. In 2010 spotted knapweed was
found mixed in with the diffuse knapweed on one parcel in the eradication area of Weld County.
In this project a seasonal staff member would be hired and start work by April 15. Activities the first
week would include drafting and mailing out letters to landowners in each of the areas along with becoming
familiar with the roads and lands in the project zones. Phone calls would start the second week. In order; the
focus would be finding the spotted knapweed infestation while addressing the diffuse knapweed, the absinth
wormwood landowners, followed by the houndstongue and Dalmatian toadflax landowners.
Landowner meetings and mapping would continue throughout the summer with treatments on the
spotted knapweed and houndstongue as soon as the plants are identified. Landowners will be treating their
own infestations of absinth wormwood, diffuse knapweed and Dalmatian toadflax. Existing cost-share funds
will be used with these landowners. The seasonal staff member will verify that this work is completed in a
timely manner.
The specific management goals and objectives include mapping all infestations of spotted knapweed
between May and June, and spraying or pulling as they are found. This will be completed no later than the
end of August. All landowners will treat the absinth wormwood on the lands in their control by the end of
June, or before seed set depending on the weather. All known infestations of houndstongue will be remapped
between May and September. All houndstongue plants identified will be sprayed or pulled as they are found.
This to
o will be completed no later than the end of August.
Additional management goals and objectives include updating the diffuse knapweed map. This will
be completed by the end of September. Landowners with diffuse knapweed on their property will treat their
infestations. At least 10 of the landowners will chemically treat their diffuse knapweed infestations by the
end of September. Dalmatian toadflax landowners will treat their infestations by either spraying or pulling
the plants. By the end of September at least 15 landowners will have addressed their infestations. Weld
County will complete 2 rounds of herbicide treatment on all targeted weed species along the county roads
between May and October. Weld County will also spray Highway 85 for CDOT in May to treat all of the
noxious weeds present in the right-of-way. This operation will be carried out from Nunn to Wyoming.

between May and October. Weld County will also spray Highway 85 for CDOT in May to treat all of the
noxious weeds present in the right-of-way. This operation will be carried out from Nunn to Wyoming.
