The daylong session, hosted by the Bureau of LandManagement (BLM) Safford Field Office, Arizona Game and Fish Department,and The Nature Conservancy, will begin at 9:00 a.m. at the WillcoxCommunity Center, located at 312 W. Stewart in Willcox, Arizona. The publicis encouraged to attend and share their ideas. Advance registration issuggested.The workshop will provide another opportunity for the public toparticipate in the development of the Aravaipa Ecosystem Management Plan,said Marlo Draper, who leads the BLMs participation on the planning team.A series of open houses were held in October to solicit the first phase ofinput prior to the start of the Plan. Management issues such as access,recreation use, protection of riparian resources and water quality,continued use of prescribed fire, and enhancement of wildlife habitat wereall identified, and will now be explored in greater detail at the March 5workshop, Draper added.The objectives of the workshop are to provide information on currentmanagement in the planning area and to create workgroups that are committedto developing the Ecosystem Plan. These workgroups will continue to meetand share input throughout the planning process. Those wishing toparticipate in the workshop should contact Draper at 928-348-4426 inadvance to select one of the seven workgroups:Recreation (hiking, hunting, birding, camping, etc.)Transportation/Motorized AccessRiparian/Water QualityUpland Habitats (soils, vegetation, grazing)Cultural Resources and Socio-EconomicsSpecial Management Areas (wilderness, Areas of Critical EnvironmentalConcern)Wildlife and Special Status SpeciesOnsite registration for the workshop will start at 9:00 a.m., followedby introductions and a short Aravaipa slide show beginning at 9:30. Afteran overview of the planning process, participants will join one of sevenbreak-out sessions. Following lunch, workgroup leaders from the BLM, AGFD,and TNC will continue to discuss the results of the October open houses,related issues, and the assigned tasks for their groups. The workshopshould end by 3:30 p.m.The Aravaipa Ecosystem Management Plan (EMP) will provide guidance for69,609 acres of public land around Aravaipa Canyon managed by the BLM and7,802 acres of private land owned by The Nature Conservancy (TNC) known asthe Aravaipa Canyon Preserve. The EMP will replace the 1988 Aravaipa CanyonWilderness Management Plan, which does not cover lands included in thewilderness expansion of the Arizona Desert Wilderness Act of 1990.The Plan will incorporate new management plans for three Areas ofCritical Environmental Concern (ACECs): Table Mountain Research NaturalArea ACEC, Desert Grasslands Research Natural Area ACEC, and Turkey CreekRiparian ACEC. It will also include National Wild and Scenic Rivers Systemsuitability recommendations made in 1994 for Aravaipa and Turkey creeks.The EMP will also incorporate the BLMs Standards and Guidelines for eightBLM-managed grazing allotments: South Rim, Painted Cave, Dry Camp, HellHole, Horse Mountain, Brandenburg, South Aravaipa, and Aravaipa.For more information about the upcoming workshop or the planningprocess, please contact planning and environmental coordinator Marlo Draper(928) 348-4426 or [email protected] or public affairs specialist DianeDrobka (928) 348-4403 or [email protected] at the BLM Safford FieldOffice.3Saturday, March 05, 2005 -10 am - 4 pmResearchers from the University of Arizona and community volunteers will unite on Saturday, March 5 to fight a foreign invader. The goal is to save Tumamoc Hill from buffelgrass. Buffelgrass - brought here from Africa for cattle forage - has the potential to be the most destructive plant pest known in the Sonoran Desert, says Desert Lab researcher Travis Bean. Tumamoc Hill is overrun with buffelgrass, which not only out-competes native plants for water and soil nutrients, but increases the risk of brush fires to dangerous levels through increased fuel loads. Infestations create a grass-fire cycle that transforms picturesque saguaro landscapes into buffelgrass monocultures. Tumamoc Hill on Tucson's west side is home to the historic Desert Laboratory and an 860-acre nature preserve. For more than 100 years the Desert Lab has been dedicated to studying plants, animals and the environment of North American deserts. The mission of the Desert Lab has become even more important in recent years. Expanding populations in the Southwest have increased the stress on natural environments that surround its growing cities. On eradication day, researchers will show how to recognize buffelgrass, and demonstrate approved techniques to remove it, including rock picks and herbicides. The event is Saturday, March 5, 10 a.m. to 4 p.m. Parking is available at nearby St. Mary's Hospital. Winter in Tucson still means plenty of sunshine most days, so wear protective clothing, including sunscreen, a hat and gloves, and sturdy shoes to navigate the rugged hillside. For more information, or to volunteer with the eradication project, call Travis Bean at the Desert Lab at 629-9455, or e-mail.Buffelgrass Removal at Tumamoc Hill, 05 March 2005Urbanization (area with > 2,500 people)Miller, 2003your Fig 5-1219 megacities (with > 10 million)18419CairoBogotaMiller, 2003your Fig 5-13Miller, 2003your Fig 5-14Pull:-jobs and income-education- innovation, culture-health carePush:-poverty- lack of land, work-famine, war- 400 cities > 1 million- 50% world’s population-poverty and slums- fast urbanization in developing worldmegalopolis205Miller, 2003your Fig
