Highway corridors in Region 2 pass
through distinct biotic communities
(biomes):
- Sonoran Desertscrub (Arizona Uplands and Lower Colorado)
- Semidesert Grassland
- Madrean Evergreen Woodland
- Plains and Great Basin Grassland
- Chihuahuan Desertscrub
- Petran Montane Conifer Forest
- Subalpine
Tucson Natural Resources Region 2 is responsible for managing land, wildlife, and vegetation inventory of 1588 miles (Map) of the following roadways:
All of the following: SR (State Routes) 75, 78, 80, 82,
83, 86, 90, 92, 181, 186, 189, 266, 286, 289, 366 and 386,
and Interstate I-19.
And portions of the following roadways:
-
I-10 from the junction with I-8 to New Mexico border
-
US 70 from county line (approximately MP 270) to New Mexico border
-
SR 77 Tucson to the junction of SR177
-
SR 79 Oracle Junction to Florence
-
SR 85 Maricopa County Line to Lukeville
-
US 191 from Douglas to milepost 220.7 south of Alpine.
The diversity of biotic communities and explosive population growth present on-going issues in the region: wildfires, flooding, noxious/invasive weeds, water/wind erosion, tree/brush encroachment. The diversity of biotic communities and explosive population growth present on-going issues in Region 3:
- Timing of pre-emergent herbicide applications to coinicide with rain events
- Extensive areas of sandy soils which are unsuitable for pre-emergent herbicide applications
- Tree and brush encroachment limiting visibility
- Tall herbaceous weeds limiting visibility
- Bark beetle infestations
- Wildland fires
The year-round resource
management projects in the Region are:
- Tree/Brush Control
- Noxious/Invasive Weed Control
- Erosion Prevention
Region 2 is involved in cooperative projects with various agencies:
- Arizona Game and Fish department to protect the Desert Massasauga Rattlesnake (Sistrurus catenatus edwardsi) and we are assisting with the Safe Harbor Agreement.
- SkyIsland Alliance to identified wildlife corridors.
- Tohono O’dom Nation to protect the desert tortoise on
the rights-of-way.
- National Park Service at Organ Pipe National Monument and the Forest Service where our roads cross their borders.
Current Projects in the
Tucson Region.
