The continued growth of the human-built environment in Pima County, Arizona will result in the “incidental take” of species that are listed under the Endangered Species Act. To avoid, minimize, and mitigate impacts to both listed and unlisted species and their habitats, Pima County is submitting this Multi-species Conservation Plan for 44 species that may be impacted as a result of the otherwise lawful activities of Pima County and its development community. The Incidental Take Permit, also called a Section 10 permit, will be for 30 years. This MSCP is part of the required documentation needed to receive an Incidental Take Permit under Section 10(a)(1)(B) of the ESA.
The Multiple Species Conservation Plan will complete the land use planning process in a conflict between competing interests on the question of growth. A path of balance was chosen by advancing the Sonoran Desert Conservation Plan. This second draft will be posted on the website and distributed to interested community and committee members. A public process will be conducted so that during 200t the document can be finalized and submitted to the U.S. Fish and Wildlife Service as part of the application for a federal endangered species permit.
Describes some of the highlights of the approach by the Science Technical Advisory Team during the study of the last three years and brings emphasis to a few of the simple guiding principles that might not have been noted during the last years of research and reporting.
Provides an overview of the issues related to monitoring the 36 species proposed for coverage under the forthcoming Section 10 permit to the United States Fish and Wildlife Service. By integrating the requirements for MSCP compliance and effectiveness monitoring with the challenges inherent in single-species monitoring, this document seeks a balance between species-specific monitoring and other habitat, ecosystem and threats-based measures (parameters). By designing such a program, Pima County will be in a better position to anticipate and adjust management actions for the conservation of covered species and the ecosystems that support them.
Complacent pollen records associated with both extinct fauna and archaeological remains argues that Southwest has been semi-arid throughout Late- and Post-Pleistocene.
Draft of report published in A.H. Schroeder, 1965, Anthropological Papers of the Department of Anthropology, University of Utah, Misc. Coll. Papers 75; 10: 85-110. Pilot study of 3 pollen samples suggests pollen chronology developed for Northern Arizona and New Mexico portions of the Colorado Plateau not applicable to SE Utah.
This study of 23 pollen samples allows recognition of a sequence of ecosystem changes occurring in central New Mexico between A.D. 1280 and 1400 and also in the 1650 - 1750 period. It also discusses the effects of such changes on aboriginal maize agriculture. Draft of the report included in Archaeological Excavations at Pueblo del Encierro.
Unpublished report, 1964
Pilot study of 3 pollen samples allows vegetation pattern reconstruction for period of occupation and suggests successful maize farming required water control technology.
