IMPORT OF LIVESTOCK AND FEEDHay, raw feeds, and straw may contain invasive plant seeds if grown in fields where invasive plants flourish and reproduce. Invasive plants can be spread into previously unoccupied areas during transport of feed materials and by laying out hay at pack stations or trail heads. Verifying that animal feed and mulch is California certified weed free before it is used in an area can help prevent the spread of invasive plants. Use of straw as mulch is covered in the preceding section. The following principles will be followed when importing livestock and feed into the park:
FRONTCOUNTRY TO BACKCOUNTRY TRAVELThese parks are fortunate. Backcountry wilderness areas in SEKI are largely free of invasive non-native plants. Even those species, such as cheatgrass (Bromus tectorum) and bull thistle (Cirsium vulgare), that have managed to colonize backcountry sites have left many drainages untouched. Protection of the parks’ wilderness vegetation from invasion by non-native plants is of the highest priority. The following guidelines will be followed to protect wilderness vegetation:
ROLES AND RESPONSIBILITIESSome of these policies may take some lead time to implement. For example, commercial pack stations with incidental business permits will need sufficient time to locate suppliers of certified weed-free feed and find the lowest prices. A quarry inspection system may take several years to finalize and implement. Divisions will have to work cooperatively to accomplish the policy with the least disruption to operations. The SEKI Superintendent issues policy and makes final decisions. He or she communicates the importance of policy to all employees. The superintendent will also communicate with owners of private inholdings and permittees asking for voluntary cooperation with this policy. The Chief of Fire and Visitor Management (Chief Ranger) ensures that heliports maintain a weed-free buffer, that equipment to build fire line is washed before entering the park, and that fire line is rehabilitated as soon as possible. He or she encourages active participation of backcountry and trailhead rangers in detecting and reporting non-native plant invasions. The Chief Ranger incorporates this policy into wilderness permits and information. The Chief of Interpretation incorporates non-native plants (threat and prevention) into interpretive message to visitors as feasible. He or she ensures that cultural landscape issues are properly considered and that the park Archeologist is sufficiently involved in the implementation of the Management Directive. The Chief of Maintenance incorporates weed-free and equipment washing specifications into contracts managed by Denver Service Center and Federal Lands Highway Administration. He or she ensures that equipment used for park operations is washed before re-entering the park or moving from place to place within the park. The Chief of Maintenance implements policy for import of livestock and feed for government stock and ensures that government pack stations maintain a weed-free buffer. He or she implements policy for soil disturbance in work by road and trail crews and ensures that all new construction includes a revegetation and non-native plant inspection component. The Chief of Natural Resources proposes policy updates and implements policy for soil disturbance in work conducted by revegetation and non-native plant crews. He or she ensures that DNR field crews prevent movement of non-native plant seed from place to place in their boots and equipment. The Contracting Officer incorporates weed-free standards into procurement of sand, gravel, road base, and other construction and restoration materials. He or she, along with the Chief of Maintenance ensures that contracts issued by the parks include weed-free and equipment-washing specifications. The Budget Officer incorporates landscaping policy into housing agreements and housing policy. The Concessions Manager incorporates these policies into concessions contracts and incidental business permits, in particular, those contracts with commercial pack stations. He or she serves as primary contact/liaison in communicating policy to permittees and owners of private inholdings, and amending permits if necessary. The Superintendent of Devils Postpile National Monument ensures that all DEPO activities and employees implement this policy. The Senior Science Advisor and his or her staff ensure that this policy is necessary and sufficient based on the best available scientific knowledge. The Ecologist (Ecological Restoration and Invasive Plant Management) serves as primary point-of-contact in administering policy. He or she consults with all divisions in surveying sites for invasive plants, writing contract specifications, developing a quarry inspection system, and incorporating policy into special use permits, incidental business permits, and concessions contracts. The Ecologist works with Concessions office and superintendent in issuing letters to cabin permittees and owners of private inholdings. Implements policy for soil disturbance in work by revegetation and non-native plant crews. ___________________________________________________________ ___________________ Richard H.
