Several Federal and State agencies in Arizona and New Mexico are collaborating on the development of a strategy for the restoration of riparian systems. The strategy that is taking shape is the development of a package of formats, methods and information that can guide local groups in developing and implementing local riparian restoration plans. The major elements of the preliminary strategy are described.

Riparian habitats historically constituted 1% of the land mass in western North America. Within the past 100 years, an estimated 95% of this habitat has been altered, degraded or destroyed due to a wide variety of land use practices such as river channelization, clearing for agriculture, livestock grazing, water impoundments and urbanization. Many authors now concur that the single most important land management practice impacting western riparian ecosystems has been unmanaged domestic livestock grazing. Over 70% of the western United States is currently being grazed by livestock in...

Determining what "desired future condition" actually means has been viewed as a moving target approach for developing ecosystem management plans. The difficulty arises from trying to define what the desired condition are for any given site. In addition, definitions may be plagued with inconsistencies, contention and argument, indeterminate time frames and less than the best knowledge available. Herein, we propose a conceptual approach called "Desirable Functional Processes," or DFP, for evaluating the ecological condition of an ecosystem or parts thereof. It is founded on the premise that...

Created in 1992 by the Arizona Legislature, the Riparian Area Advisory Committee (RAAC) developed recommendations for protecting, maintaining, and restoring riparian areas in Arizona. These recommendations were submitted to the Legislature and to the Governor after concluding a two year period of study and discussion. The RAAC, consisting of 34 members broadly representative of federal and state agencies, tribal government, counties, municipalities, major economic resource user groups as well as environmental and recreational organizations, agreed on a Conservation Goal and on the broad...

The New Mexico State Land Office has initiated a rare plant survey of state trust land, an inventory and assessment of riparian areas on the trust land, and the development of a biological resources data base and information management system. Some riparian sites that still belong to the trust have been negatively impacted by livestock such that biological quality and ecological integrity of these sites have been reduced. Some sites on state trust land may have high potential for the development or restoration of riparian forests which could serve as essential habitats for neotropical...

Currently an organization called the Verde Watershed Association is the central point for consensus building and public involvement in water issues in the Verde River Watershed. The association is the out growth of efforts towards the resolution of watershed issues without passing new laws, initiating regulations, or entering the win-lose arena of litigation. The association is premised on the idea that truly effective river management and protection strategies cannot succeed without local consensus and support.

The purpose of this panel is to review past, present, and future human needs and desires associated with riparian environments. Our focus concerns the diverse demands, interactions, and expectations that people have for the riverine lands. The discussion is designed to take place within historic, economic, and social/cultural contexts.

The Pueblo of Isleta, located five miles downstream from Albuquerque, and the NM Water Quality Control Commission has established strict water quality standards for the Rio Grande, and it has become necessary for the Albuquerque Public Works Department to pursue methods to enhance the purity of treated municipal wastewater effluent produced at the Southside Water Reclamation Plant (SWRP). In response to requirements in a National Pollutant Discharge Elimination System (NPDES) permit, issued in June 1994 by the US Environmental Protection Agency (USEPA), design has begun for additional...

Seiiorito Canyon, a non-functional, degraded tributary stream of the Rio Puerto in New Mexico, has begun to respond to management strategies by the Bureau of Land Management. Restoration of the riparian ecosystem has been accomplished principally through livestock grazing management and planting and reestablishment of the native cottonwood/willow communities. The use of riparian pastures constructed along the stream was necessary to "jump-start" the system and allow total grazing deferment from 3 to 5 years.

Much is yet to be learned about the importance of bats in Southwestern ecosystems, their ecological requirements, and how habitats should be managed to sustain these important species. A first step towards these goals is to determine what species exist in different habitats and across what geographic ranges. The objective of this study was to identify the bat species which use pinyon-juniper habitats of the Middle Rio Grande Basin. Ten pinyon-juniper sites with permanent water on the Cibola National Forest were mist netted four times from May to September 1995. Sixteen bat species were...
