Management Conflicts: Prairie Dogs and Irrigated Agriculture

Relocation challenges 

While the city conducts prairie dog relocations – including recent efforts to remove prairie dogs from development sites, city parks and OSMP agricultural lands – relocations are logistically complicated and expensive. Those challenges include:

  • OSMP currently has more than 1,257 acres of irrigable agricultural land that overlaps with prairie dog occupation. But given cost, time, contractor availability and permitting requirements, past relocation projects have only been able to accommodate the removal of up to 40 acres of prairie dog colonies per year.
  • There are many plant communities, such as xeric tallgrass prairie and other rare plant communities, and animal species like grasshopper sparrows that do not thrive where there are active prairie dog colonies, making some grasslands poor choices for relocating prairie dogs.  
  • Open space relocation sites must also meet specific standards to obtain a relocation permit from Colorado Parks and Wildlife.
  • OSMP’s ability to relocate prairie dogs is further constrained by neighboring landowner concerns about relocating prairie dogs near their property, and state law makes it difficult to move prairie dogs to available sites outside of Boulder County. 

How does the City of Boulder manage prairie dogs?

Current open space plans, including the recently approved OSMP Master Plan, seek to maintain the viability of agricultural operations by reducing impacts from prairie dogs on irrigated lands while supporting ecologically sustainable prairie dog populations across the larger landscape.  

Other city plans and policies – including the Wildlife Protection Ordinance, the Urban Wildlife Management Plan and the Grassland Ecosystem Management Plan – also strive to strike a balance between protecting and maintaining healthy, thriving prairie dog populations and safeguarding natural communities and other land uses that conflict with prairie dog occupation.

  • Open Space and Mountain Parks Master Plan pdf: The OSMP Master Plan, accepted and adopted by the Boulder City Council in September 2019, has a Tier 1 strategy related to the management of agricultural lands occupied by prairie dogs. Tier 1 Master Plan strategies are those that the department will focus on first while scaling all other work to align with available funding. The strategy seeks to address conflicts between agriculture and prairie dogs to maintain the viability of agricultural operations by reducing impacts from prairie dogs on irrigated lands while supporting ecologically sustainable prairie dog populations across the larger landscape.
  • Prairire Dog Working GroupA city Prairie Dog Working Group (PDWG) – made up of 12 community members representing a variety of viewpoints – reviewed the city's prairie dog management policies and practices and made recommendations for changes to existing policies and new initiatives to help manage prairie dog colonies and habitats. In April and May 2019, both the City Council and the city’s Open Space Board of Trustees approved city staff’s plan to implement many of the working group’s recommendations. The continuing high abundance of prairie dogs on the city’s northern agricultural properties was part of both the council’s and the OSBT’s discussion of the PDWG recommendations last year. During those discussions, both the council and the OSBT gave OSMP direction to explore whether, when, and how additional prairie dog management tools might be effective in reducing impacts to city irrigable agricultural lands.  
  • Agricultural Resources Management Plan pdf: This plan, accepted by the City Council in 2017, seeks to decrease impacts to agricultural production from prairie dog occupation and to evaluate options to manage prairie dogs and agricultural conflicts better. Strategies available for implementation within the existing policy framework include:

    • Re-applying the prairie dog colony management area designation criteria to agricultural lands to help evaluate and prioritize properties for removal.
    • Identifying a process for rapid response restoration and recolonization prevention of agricultural properties when prairie dogs are removed, die off or are reduced in spatial extent.
    • Exploring changes to grazing regimes, vegetation restoration and non-native vegetation management techniques to encourage the faster recovery of vegetation in potential relocation sites.
  • Grassland Ecosystem Management Plan pdf: Accepted by City Council in 2010, this plan provides a framework to conserve grasslands and prairie dogs and their associates by establishing goals and objectives to measure success in prairie dog conservation and management.  It also includes criteria to guide relocation of prairie dogs to, from, and within the OSMP system and defines land management designations for every prairie dog colony mapped. The Grassland plan also includes strategies to help support sustainable agricultural operations and address conflicts between agriculture and prairie dogs. 

    The 2019 OSMP Master Plan, recently accepted and adopted by the Boulder City Council, provides direction for OSMP to update the plan and continue managing this important ecosystem by considering all elements and processes of natural systems rather than focusing on one species or attribute at a time.

  • Wildlife Protection Ordinance pdf: This ordinance prohibits anyone from using lethal control measures for prairie dogs without first having obtained a lethal-control permit from the city. For a permit to be issued, the landowner must satisfactorily demonstrate that all non-lethal options for managing prairie dogs on a site were considered and were found not feasible. This municipal code applies to the city itself and all city lands even if they are owned in county jurisdiction. The ordinance also protects prairie dog burrows from damage.

  • Urban Wildlife Management Plan (UWMP)It establishes a framework for making urban wildlife management decisions and outlines a set of actions for long-term management of human-wildlife conflicts. The Black-tailed Prairie Dog element was approved by City Council in 2006 and emphasizes humane, non-lethal control of prairie dogs whenever feasible.
  • Collaborative Conservation Plan: In 1996, the City of Boulder developed a habitat conservation plan to help protect prairie dogs. The department worked with a committee of farmers, rural residents, environmentalists, animal rights advocates, land managers and interested citizens to develop a set of goals for prairie dog management on OSMP. The plan sought to reduce the conflicts between prairie dogs and adjacent land uses by establishing a system of prairie dog habitat conservation areas throughout the OSMP land system.
