Florida Work Station is significant as the administrative site of the Santa Rita Experimental Range (SRER), a roughly 80-square mile area of rangeland operated for over a century as an agricultural and ecological research laboratory. The SRER ...is widely recognized as the first established and oldest continuously operated experimental rangeland facility in the United States (Price and McClaran cited in Gillespie The establishment of the SRER dates to and is inextricably linked to Proclamation the second U.S. land protection proclamation enacted by executive order under President Theodore Roosevelt that set aside land for the development of the Santa Rita Forest Reserve.
SRER is also intimately connected to the parallel establishment of the US Forest Service and the designation of national forests in Arizona (Boissoneault Farrell et al. Gillespie Joint interest in the long-term effects of century cattle overgrazing and rangeland degradation in Arizona between the University of Arizona (UA), the federal government, and the territorial government in Arizona ultimately led to creation of the SRER (Gillespie The Florida Work Station is a complex of buildings and associated landscape features in Florida Canyon in the Santa Rita Mountains south of Tucson, Arizona. The Station is located on Coronado National Forest land and is currently operated by the University of Arizona under a special use permit.

With an elevation of above sea level, it is situated at the base of Florida Canyon in the Santa Rita Mountains at the southern edge of the Santa Rita Experimental Range (Figure 2). Use as the administrative center for the Santa Rita Experimental Range has affected the natural landscape of the Florida Work Station. Its landscape is characteristic of Sonoran Desert chaparral and grasslands zones. Its climate can expect arid conditions with an average rainfall of about 20 at this location. The area has high temperatures and monsoons during the summer months with cool temperatures during the winter months. The Santa Rita Forest Reserve was established in on acres of well- forested land as a response to overgrazing and rangeland degradation.
Four- fifths of the Forest Reserve was mesa and foothills land, including indigenous cacti, perennial bunchgrass, shrubby mesquites with solid mesquite trees along waterways (Sayre With the construction of the Florida Work Station taking place between and and the establishment of an active rangeland research program, it was observed that large numbers of shrubs were displacing natural grasses and cacti, and invasive plant species, such as Lehmann Lovegrass and burrow weed were becoming predominant. Much of the dominance of shrubs in the area is attributed to grazing patterns along waterways over time. The vegetation currently located at the Florida Work Station continues to demonstrate patterns of animal and human activity.
The site is located adjacent to the Florida Creek on its east side, and a perennial spring is located about four miles upstream (south) through the canyon.1 This site contains native shrubs, mesquite trees, prickly pear cacti, agave, and Lehmann Lovegrass as well as some introduced species such as a pomegranate tree, olive tree and oleander shrub. Built elements on site include buildings, roads, masonry and dry stack retaining walls, rock drainage features and rock paths which define the spatial organization of the site. At the time of its creation under President Theodore Roosevelt the Santa Rita Experimental Range was owned by the Department of the Interior. In the 1 Brett Blum, University of Arizona site manager.

For most of its existence, the function of the Florida Work Station has been the headquarters of the Santa Rita Experimental Range, where the housing, gas station, warehouses, and offices are located.
Under its management by the University of Arizona, its primary functions are for ecological research support, education, outreach, and community engagement. The work station provides laboratory space for research on desert grassland ecology (USDA Forest Service It hosts groups of all ages for educational programs covering its history and scientific research, based on rangeland science, ecology of semi-arid ecosystems, agriculture, and cattle ranching. For the first 30 years, the focus was on how to restore forage plants decimated by the cattle boom and how to measure range resources for management and administration (Sayre From to the focus changed to vegetation: measuring methods, carrying capacity, and revegetation.
From to the focus remained on revegetation or restoration of native perennial grasses (Sayre In the research focus changed to include many new areas including cattle diets, soil nutrients and their importance, and plant root systems. Since when the management was transferred to the University of Arizona, the interests have moved from livestock production to issues such as climate change, ecological restoration, watersheds, and wildlife (Sayre The Florida Work Station was designed and constructed as the headquarters for the Santa Rita Experimental Range (Figure 1). The spatial organization and cluster arrangement of this district remains largely unchanged since the original site development.
The entrance begins with the relocated Old Gas Station, which is likely to be demolished due to its deteriorated condition, and a long driveway which is about 15 wide up to the central common area. The central area is made up of the administration buildings, garages, and the caretaker s house. There is a group of three residential buildings on the west side of the site at a higher elevation than the center. At the top or southern end of the site are the warehouses and water tanks. The southern boundary is delineated by the fence behind the deconstructed warehouse; the west boundary by a path behind the cottages; the east is the trail just beyond Florida Creek; and to the north is the entrance gate. The northern entrance of the Florida Work Station features the Front Gate.
It has two stone masonry walls about 3 tall with 7 tall pillars about 15 apart for vehicle and visitor access. The pillar to the west says, Santa Rita Experimental FLORIDA WORK STATION HALS NO. AZ-29 PAGE 4 Range, and the pillar to the east says, University of Arizona (Figure 3). Behind the western pillar and wall sits a large three-trunked Oak tree. It is also pictured in a photo of the same entrance to the Florida Work Station facing south. The Old Gas Station is located southwest of the Front Gate. It is a wooden structure that is dilapidated and no longer retains its integrity. It was relocated from south of the site where the Old Gas Pump is located to its current location. Southwest is a fork in the USFS trail.
Along the eastern USFS trail a possibly contributing reddish-brown wooden post is located under a mesquite tree. Further south on the western side of the trail there is a rocky, grassy drainage lined with Oak trees running downhill along the trail. Located closest to the western USFS trail is the contributing Office built in February of by the U.S. Forest Service. It has yellowish brown siding with brownish trim and has an open porch with two entrances and a non-contributing metal roof. In it was whitish with dark trim and window awning canopy coverings for windows.
Its purpose has not changed but it is being considered as a place for residence or an Interpretive Center ( Florida Station: Planning the Next Century : Directly north of this dwelling is a flagpole with a stacked stone base (Figure 4). North of the flagpole is a masonry retaining wall about 3 in height. There are four steps embedded in this retaining wall that reach into the hill north. There is a terrace with a tree surrounded by a low stone wall southeast of the house. On the hill south of the Office is a dry-stacked stone wall. Southwest of this location is a weathered, white wooden box housing a thermometer gauge with a metal base (Figure 5). It is a contributing structure. In the same region is a mortared stone path on an overgrown, grassy hill.
West of the Office is a stone path mortared in place approximately 9 wide with a stone drain embedded towards the bottom leading uphill towards dwellings. Along the northwestern site boundary is a vista with a gravel pad area ringed with stone. There is a tree with a constructed tree well with a depth of approximately 2 . Along the western side of the USFS Trail is a depressed transition from asphalt to dirt leading northwest away from the trail. It appears to be used for flood or water control. The southeastern side of the road is lined with rocks. There is a rock-lined path that leads through the woodland area to the Florida Creek. At the end of this path is a weathered hollow concrete barrel.
Florida Creek is beyond, including a small pool of water which may been used as a watering hole. Along the eastern edge of the site boundary is a concrete pad that may have functioned as structure foundation. Directly south of the concrete pad is a weathered cement water trough, which is 8 -2 x 3 -8 x 2 -1 (Figure 6). There is an additional larger path leading from Florida Creek west towards the trail lined with stone which is about 6 wide. This leads towards the Office. The eastern side of the trail has dry stacked retaining walls that support this path. There is a C on top (Figure The path below this feature is an asphalt road that leads to the trail and Office. West of the trail is the flat parking area.
East of the parking area are sycamore (Platanus wrightii) and juniper (Juniperus californica) trees. West of FLORIDA WORK STATION HALS NO. AZ-29 PAGE 5 the parking area is a masonry stone retaining wall that surrounds the C-6 Martin House. The C-6 Martin house is a contributing building constructed during June of by the US Forest Service. Today it has yellowish brown side paneling and brown trim with a green metal roof that is non-contributing. It has an enclosed porch entrance and is used as housing ( Florida Station: Planning the Next Century : West of the Martin House is a dry stack retaining wall split by an oak tree. The C-5 Bunk House is located southwest of the C-6 Martin House. It is a contributing structure that was built during the May of by the US Forest Service.

Southwest of the C-5 Bunk House is a terraced hill with stone stairs leading up to the terrace (Figure Moving southeast from C-5 Bunk House is the Administrator s Office/ Dwelling. It was built during June of by the US Forest Service and was remodeled during the winter of by the agency. At the time it was white with a dark trim and had vines growing along the exterior walls on the eastern and northern sides, as noted from a picture.
Today it has dark wooden side paneling with brown trim and a green metal roof. It is used for housing ( Florida Station: Planning the Next Century, Across the USFS Trail east is the C-9 Officer-In-Charge Dwelling. It was built during December by the US Forest Service and was remodeled during the January of by Works Progress Administration (WPA). It was white with a darkish trim. It has a Gambrel-form porch extension. It has a masonry stone chimney which is included in a photo from ( Florida Station: Planning the Next Century, Today it is white with green trim and a green metal roof. It is used as the station manager's dwelling (Figure 7). In the central area there is a building which is currently used as the Classroom on Figure 1). This is where educational outreach takes place.
It was previously used for carpentry. Across the road is the building which is currently the bathrooms. It was where the gas station was located before its transfer to the front of the site. The original gas pump is still standing in the front. It is dark red and is 5 -6 tall. Next to it is the Main Garage on Figure 1). This building s current use is storage for tools and other maintenance equipment. It was previously used for the main garage. The exterior has remained the same with the exception of the roof, which has been updated. All buildings were renovated with the same green metal roofs to prevent further damage. Moving from the center to the west is the residential area. Going from south to north, first is the Cottage on Figure 1).
Due to its location along the FLORIDA WORK STATION HALS NO. AZ-29 PAGE 6 hillside, the front foundation of the home is raised to be level with the back half. This foundation is made of stone and mortar masonry which is similar to the retaining wall alongside the road. The second cottage is the Cottage on Figure 1). It is located further back from the road than the other cottages and has a stone masonry path to the front door. There are stone masonry retaining walls terracing the front of the cottage. On the exterior there is a stone patio. The third cottage is the Cottage on Figure 1; Figure 7). This cottage has a fenced-in side yard with non-native plants including an olive tree (Olea europaea) and oleander (Nerium oleander) on the left side.
On the right side is a stone masonry staircase leading to a small masonry slab outside the door. The right side also houses a pomegranate (Punica granatum) tree. This cottage has a stone and mortar foundation similar to the Cottage. These cottages have had the same use since their creation, but some features have been modified on both interior and exterior, where the roof was replaced with a green metal roof and half-circle gutters were added. Moving to the south, there are two storage garages, C-7 and and respectively, on Figure 1), parallel across the path from one another. Located next to these garages is one of two water tanks (Figure 8).
This tank is the older of the two tanks on site, estimated to date back to the This metal tank was previously used as a fish tank and has since been used to provide water to the site for fire remediation. At the southernmost end of the site (upper part of the site), there was another warehouse, but it was removed due to the lack of maintenance and integrity. All that remains is a 20 x 40 slab where it once stood on Figure 1). Stone masonry including dry rock and stone and mortar are prevalent throughout the site due to the easy availability of materials. Along the exterior of the roads, buildings, and along the hillside are stone masonry retaining walls. Some are dry stone masonry and others are stone and mortar masonry (Figure 9).
These walls navigate the circular path around the site along the cottages, warehouse, and extra walkways. In the central area there are three trees all, with stone tree wells surrounding them. One tree, located next to the bathrooms, has a modern fire hose inside the ring. Another, more central, has nothing inside the ring. The third tree, located outside the Classroom, has a stone water spigot (Figure A modern addition to the site is the picnic area located between the Classroom and the creek, with stone and mortar masonry retaining walls surrounding the benches. This area includes a historic stone barbeque grill to the side of the non- contributing picnic seating area (Figure 1).
History: The Santa Rita Mountain range, located 40 miles southeast of Tucson, Arizona, has been the site of subsistence and settlement activity and cultural life for Indigenous communities for thousands of years (Buttery The mountain range is a traditional cultural property of the Tohono O odham and is FLORIDA WORK STATION HALS NO. AZ-29 PAGE 7 acknowledged as a place of traditional cultural importance to the Western Apache, the Chiricahua Apache, the Hopi, the Zuni, and the Pascua Yaqui (Griset et al. Spanish explorers and missionaries introduced livestock to the area in the late century and subsequent settlement by Hispanic families (Griset et al. established ranching culture and land-use traditions to the area.
This has made the area of historic cultural significance to many multi- generational and multi-cultural Spanish-Mexican and Mexican-American ranching families, a few of whom still own and operate historic ranches located at the base of the Santa Rita Mountains today. After the Gadsden Purchase and with the Homestead Act many Anglo and international investors recognized the economic potential of ranching, mining, and other agricultural and commercial enterprises in the Santa Rita Mountains and settled in the area. During the U.S. Territorial Period in Southern Arizona a series of executive orders and federal acts issued under presidents William McKinley and Theodore Roosevelt were enacted to both secure and preserve public land in southern Arizona for the United States.
These resulted in the creation of the Santa Rita Forest Reserve in later absorbed into the Coronado National Forest a two-million-acre, noncontiguous national forest, in As early as a joint interest developed between the U.S. government and scientists at the University of Arizona (UA) in the study of rangeland degradation in southern Arizona.
