Vascular Plants of Arizona Project (VPAP)
Botanists at the herbarium of Arizona State University and The University of Arizona have formed an editorial committee with the intent of producing a new manual to the Vascular Plants of Arizona. As treatments are completed, they are published in the Journal of the Arizona-Nevada Academy of Science. For more information concerning this project, visit the offical VPAP site.
Roskruge Mountains
1995 was an incredible flowering year in southern Arizona; during the flowering season, groups of botanists from the Herbarium and the Department of Ecology & Evolutionary Biology made several trips to the Roskruge Mountains (Pima county), west of the Tucson mountains. This list based on those trips & is by no means complete!!! Principle Contributors: M. Fishbein, P. Jenkins, L. McDade, M. McIntosh
Sawtooth Mountains
(K. Mauz, University of Arizona)The Sawtooth Mountains rise 1000 feet above the Picacho Basin, southwest of Eloy in Pinal County, Arizona. The range is dominated by remnant volcanic cliffs and low hills, and surrounded by old to ancient bajadas covered with Sonoran desertscrub vegetation. A playa and sand sheet lie at the southern end and support unique assemblages of plants, and the Greene Wash borders the range on the east where neighboring farmland begins. This floristic work was conducted during the 1998 El Ni?o and the exceptional monsoon season of that year. The Sawtooth Mountains became part of the Ironwood Forest National Monument in June 2000.
West Branch of the Santa Cruz River, Tucson
(K. Mauz, University of Arizona)The West Branch of the Santa Cruz is a dry wash and arroyo south of downtown Tucson, Arizona, that parallels the Santa Cruz River from its origins south of the Mission San Xavier through the upper Tucson Basin, until it joins the main channel just south of Sentinel Peak. This floristic work was conducted in 2001 along a stretch between Silverlake Road and Ajo Way, and includes plants of the channel, mesquite forest, and floodplain east of Mission Road. The parcel was acquired by Pima County for habitat conservation in January 2002.
Tucson Mountains
(Renée J. Rondeau, Thomas R. Van Devender, C. David Bertelsen, Philip D. Jenkins, Rebecca K. Van Devender, and Mark A. Dimmitt)The Tucson Mountains are a small, isolated desert range in southern Arizona, west of Tucson. They are located in the ecological transition between the Sonoran Desert and higher biotic communities including desert grassland, chaparral, and montane woodlands and forests. Here we present an annotated checklist of the vascular plant species of the Tucson Mountains, descriptions of the vegetation and habitats, and evidence of changes in species distributions this century.
