SOUTHWEST RANGELAND INVASIVE PLANTS INITIATIVE
OBJECTIVES:
Three primary goals are defined for this project:
- 1) Raise public
awareness of the economic and ecological threats of invasive plant species in the
Southwest U. S.,
- 2) Encourage citizens to participate in invasive plant monitoring,
control and prevention efforts, and
- 3) Strengthen the institutional infrastructure for
invasive plant management in the Southwest. Research and extension programs will be
designed to address economic, social, psychological, cultural, and institutional
infrastructure questions and issues that are pertinent to the development of communitybased,
grassroots weed management efforts. Research findings will contribute to the
evaluation of the overall success of the project, and will help guide future Extension
efforts.
Economic objectives are to:
- 1) Perform a cost-effectiveness analysis for an
integrated weed-management program on a given landscape, and
- 2) Perform a benefit cost analysis on the entire landscape using the least-cost-plus model.
Social/Psychological/Cultural objectives are to:
- 1) Determine the type and level of involvement of each kind of group in invasive plant management,
- 2) Identify the factors that lead to increased involvement and effectiveness in invasive plant management by
citizens' groups, or that deter involvement,
- 3) Identify the most effective methods of
recruiting and training citizens in different types of groups for invasive plant
management,
- 4) Identify individual characteristics and institutional and situational
factors that lead to sustained participation in community-based resource management
generally, and invasive plant management specifically,
- 5) Determine how well each type of group is integrated into local and regional institutional frameworks for invasive plant
management, and
- 6) Evaluate the success of Extension programs aimed at recruiting
and training citizens' groups in invasive plant management.
Institutional Infrastructure objectives are to:
- Increase the speed and efficiency which new invasions are
reported and mapped,
- Improve planning and coordination to promote rapid and
effective responses to new infestations, and
- 3) Achieve these objectives by integrating
community groups and volunteer rapid response teams into the institutional framework
for invasive plant management.
APPROACH:
We propose a multi-disciplinary, multi-institution, multi-state outreach and
research project that will evaluate low-cost, community-based approaches to
management of invasive plants. Research will address economic, social, psychological,
and institutional infrastructure questions and issues that are pertinent to the
development of community-based, grassroots weed management efforts. Results of this
research will be used to develop and expand extension programs that are specifically
tailored to constituencies, policy contexts, and invasive plant threats affecting range and
forestlands in the Southwestern United States. However, the general conclusions and
methods can be applied to extension activities in any U.S. location or for any agricultural
land type where plant invasions are incipient or thought to be imminent, but have not yet
reached epidemic proportions. The desert Southwest (Arizona, New Mexico, southern
Utah and southwestern Colorado) contains some of the most biologically distinctive,
visually striking and nationally treasured landscapes in North America. Plant invasions
in this region - defined ecologically by the Sonoran, Chihuahuan, and Colorado Plateau
deserts and their associated grasslands, mountains, and riparian areas - occur widely
but have not yet changed these landscapes as in regions to the north and west.
However, rangelands in the Southwestern U. S. are threatened by large-scale
invasions: yellow starthistle (Centaurea solstitialis), leafy spurge (Euphorbia esula), and
spotted knapweed (Centaurea maculosa) have all been identified in the region and
Russian knapweed (Acroptilon repens) has been reported in more than half of the
region's counties (Mullin et al. 2000). Due to the relatively recent and small-scale nature
of these invasions, we believe the opportunity exists to eradicate existing infestations
and effectively prevent future invasions using timely, low-cost early detection and
control strategies. However, because invasive plants have not yet permeated our
ecosystems, public awareness of the threat is low and the institutional infrastructure and
fiscal resources for invasive species management are weak (Cramer 1995). The
technical knowledge exists to control invasive plants in the Southwest. What we lack are
effective means of educating and mobilizing the public to act. This initiative will provide
social, psychological, and economic research essential to developing extension
programs that will expand public awareness and community involvement in invasive
species management. It will also identify ways to improve coordination among local,
state, and federal authorities, thus addressing the goal of the President's Executive
Order on Invasive Species of February 1999.
NON-TECHNICAL SUMMARY:
This is a multi-disciplinary research and cooperative
extension project that will promote and evaluate low-cost, community-based
approaches to managing invasive plants in the Southwestern U.S. Research projects
are designed to answer economic, psychological, and cultural questions pertinent to the
development of collaborative stewardship for integrated weed management. Research
results will guide the development and expansion of extension and outreach programs
that are specifically tailored to local constituencies, policy contexts, and invasive plant
threats affecting range and forestlands in the Southwestern U. S. However, our general
conclusions and methodologies can be applied throughout the U. S., wherever incipient
or imminent plant invasions have not yet reached epidemic proportions.
PROGRESS: 2001/01 TO 2001/12
This is a multi-disciplinary research and cooperative extension project that will promote
and evaluate low-cost, community-based approaches to managing invasive plants in the
Southwestern U.S. Research projects are designed to answer economic, psychological,
and cultural questions pertinent to the development of collaborative stewardship for
integrated weed management. Research results will guide the development and
expansion of extension and outreach programs that are specifically tailored to local
constituencies, policy contexts, and invasive plant threats affecting range and
forestlands in the Southwestern U. S. Several surveys on invasive plant management
have been designed. One was pilot tested and sent to some 50 local invasive plant
management organizations, including county programs, weed management areas,
weed districts and volunteer groups in the Colorado Plateau and Southwest desert
regions of Arizona, New Mexico, Utah and Colorado. To date 72 % of the survey
recipients have responded, data has been entered into a database, and preliminary
analyses have been conducted. We expect to complete survey analysis by early 2003.
Another survey was developed to measure Southwest citizens knowledge about weeds
and weed management, their attitudes toward weeds and management methods, and
their willingness to participate in volunteer weed management activities. Separate
surveys were designed for different parts of the Southwest with different invasive plant
problems (southern Utah, northern/central Arizona, southeastern Arizona, southern
Rockies). These surveys were then mailed to 2,700 citizens in the region. Survey
administration was completed in Summer 2002, and detailed analysis is now under way.
Extension programs have included a 2-day Arizona Noxious, Invasive Plant Summit
held in Tucson in April 2002, and a 3-day Noxious, Invasive Plant Short Course held in
Farmington, NM in late July of 2002. One of the outcomes of the Summit was to initiate
the development of a Strategic Plan for Noxious, Invasive Plant Management for the
state of Arizona. A web site is being developed that will chronicle the results of our
research and extension projects. Another Short Course is being planned for July 2003.
IMPACT: 2001/01 TO 2001/12
We expect our survey data will provide the first systematic and quantitative description
of the different types of local weed management organizations working in the
southwest, and enable us to assess the relative effectiveness of groups with and
without the participation of county government, multiple agencies, and citizen
volunteers. These results should be useful in guiding invasive plant policy and efforts to
organize community-level weed management groups. As a result of the Arizona
Noxious, Invasive Plant Summit we have begun to show weed managers across the
region what citizens knowledge and attitudes currently are, how those attitudes are
formed, and what their consequences are for improving weed management.
