CAP-2 proposes to extend long-term study of central Arizona and metropolitan Phoenix, a desert region supporting agricultural and urban/suburban land uses while undergoing rapid urbanization and population growth. CAP studies human drivers and feedbacks of ecological change. Previous work concentrated on the central themes of urbanization patterns and processes altering the city's ecological conditions and surrounding environment, and ecological feedback-social system interactions. CAP-2 reorganizes the program into five new Integrative Project Areas (IPAs) to aid in the explicit inclusion of socioeconomic drivers and feedbacks: 1) land-use and land-cover change, 2) climate and ecosystem dynamics, 3) water policy, use and supply, 4) material flux and socio-ecosystem response, and 5) human control of biodiversity. The modus operandi for long-term monitoring, experiments, information management, site management, network participation and education/outreach was established during CAP-1 pilot projects. Projects continued into CAP-2 include: long-term monitoring at 200 sites across CAP; historical analyses of land use; classification of land cover; documentation of change in land cover and use; river monitoring above and below the city; and establishment of intensive sites for in-depth climatic, ecological, and social surveys and experiments. Three long-term experiments will be continued and a fourth initiated (a long-term factorial N+P fertilization along a deposition gradient). The recently established North Desert Village "experimental suburb" will be the first experimental study of its kind, with manipulations of vegetation types and irrigation methods alongside examination of people-ecological environment interactions at the neighborhood scale. Broader Impacts. The broader impacts of the proposed CAP project include: 1) raising the profile and awareness of urban ecology in both science and society, 2) contributing to education and outreach at all levels, 3) producing and maintaining a comprehensive, long-term database of ecological and social variables for a rapidly changing socio-ecosystem, and 4) promoting knowledge exchange with community and governmental decision makers. Ecology Explorers, CAP LTER's K-12 education-outreach program, will see continued growth while maintaining its existing diversity of programs and working toward district-wide adoption of the Ecology Explorers curriculum. Two new programs are introduced to promote undergraduate involvement, including the Communities of Research Scholars and Interns. CAP LTER participants developed the ASU IGERT program in urban ecology and will continue to support graduate participation in research, introducing summer support for independent research in CAP-2. Information management will continue to develop innovative new techniques to preserve the long-term integrity and accessibility of the CAP LTER database. Finally, for knowledge exchange, CAP LTER will continue to partner with several related projects and initiatives in science-policy outreach relating to the urban environment.

CAP-2建议延长对亚利桑那州中部和凤凰城大都市的长期研究，这是一个沙漠地区，在经历快速城市化和人口增长的同时，支持农业和城市/郊区土地使用。CAP研究生态变化的人类驱动因素和反馈。以前的工作集中在改变城市的生态条件和周围环境的城市化模式和过程，以及生态反馈社会系统的相互作用的中心主题。CAP-2将该计划重组为五个新的综合项目领域（IPAs），以帮助明确纳入社会经济驱动因素和反馈：1）土地利用和土地覆盖变化，2）气候和生态系统动态，3）水政策，使用和供应，4）物质通量和社会生态系统响应，以及5）人类对生物多样性的控制。长期监测、试验、信息管理、现场管理、网络参与和教育/外联的工作方式是在CAP-1试验项目期间确定的。在CAP-2中继续开展的项目包括：在整个CAP的200个地点进行长期监测;土地利用的历史分析;土地覆被分类;记录土地覆被和利用的变化;城市上下的河流监测;以及为深入的气候、生态和社会调查和实验建立密集地点。三个长期试验将继续进行，第四个开始（长期因子N+P施肥沿着沉积梯度）。最近建立的北沙漠村“实验郊区”将是第一个此类实验研究，在邻里尺度上对植被类型和灌溉方法进行操作，同时检查人与生态环境的相互作用。更广泛的影响。拟议的CAP项目的更广泛影响包括：1）提高城市生态学在科学和社会中的形象和意识，2）促进各级教育和宣传，3）为快速变化的社会生态系统建立和维护一个全面的长期生态和社会变量数据库，以及4）促进与社区和政府决策者的知识交流。生态探索者，CAP LTER的K-12教育推广计划，将看到持续增长，同时保持其现有的方案的多样性，并努力争取全地区采用生态探索者课程。引入了两个新的计划，以促进本科生的参与，包括研究学者和实习生的社区。CAP LTER参与者开发了ASU IGERT城市生态学计划，并将继续支持研究生参与研究，为CAP-2的独立研究提供夏季支持。信息管理部门将继续开发创新的新技术，以保持联合呼吁程序长期应急措施数据库的长期完整性和可访问性。最后，为促进知识交流，长期应急能力建设方案将继续与城市环境科学政策外联方面的若干相关项目和举措结成伙伴关系。
