Description
ABSTRACT The Phoenix Four Rivers Flora is an inventory of all the vascular plants growing along the Salt, Gila, New and Agua Fria Rivers, and their tributaries in the Phoenix Metropolitan Area during the years of the study (2009-2011). This floristic inventory documents the plant species and habitats that exist currently in the project area, which has changed dramatically from previous times. The data gathered by the flora project thus not only documents how the current flora has been altered by urbanization, but also will provide a baseline for future ecological studies. The Phoenix Metropolitan Area is a large urbanized region in the Sonoran Desert of Central Arizona, and its rivers are important for the region for many uses including flood control, waste water management, recreation, and gravel mining. The flora of the rivers and tributaries within the project area is extremely diverse; the heterogeneity of the systems being caused by urbanization, stream modification for flood control, gravel mining, and escaped exotic species. Hydrological changes include increased runoff in some areas because of impermeable surfaces (e.g. paved streets) and decreased runoff in other areas due to flood retention basins. The landscaping trade has introduced exotic plant species that have escaped into urban washes and riparian areas. Many of these have established with native species to form novel plant associations.

Description
A floristic analysis is essential to understanding the current diversity and structure
of community associations of plants in a region. Also, a region’s floristic analysis is key not only to investigating their geographical origin(s) but is necessary to their management and protection as a reservoir of greater biodiversity. With an area of 2,250,000 square kilometers, the country of Saudi Arabia covers almost four-fifths of the Arabian Peninsula. Efforts to document information on the flora of Saudi Arabia began in the 1700s and have resulted in several comprehensive publications over the last 25 years. There is no doubt that these studies have helped both the community of scientific researchers as well as the public to gain knowledge about the number of species, types of plants, and their distribution in Saudi Arabia. However, there has been no effort to use digital technology to make the data contained in various Saudi herbarium collections easily accessible online for research and teaching purposes. This research project aims to develop a “virtual flora” portal for the vascular plants of Saudi Arabia. Based on SEINet and the Symbiota software used to power it, a preliminary website portal was established to begin an effort to make information of Saudi Arabia’s flora available on the world- wide web. Data comprising a total of 12,834 specimens representing 175 families were acquired from different organizations and used to create a database for the designed website. After analyzing the data, the Fabaceae family (“legumes”) was identified as a largest family and chosen for further analysis. This study contributes to help scientific researchers, government workers and the general public to have easy, unlimited access to the plant information for a variety of purposes.
