We are upgrading the repository! We will continue our upgrade in February 2025 - we have taken a break from the upgrade to open some collections for end-of-semester submission. The MS-GIST Master's Reports, SBE Senior Capstones, and UA Faculty Publications collections are currently open for submission. Please reach out to repository@u.library.arizona.edu with your questions, or if you are a UA affiliate who needs to make content available in another collection.

Abstract
Shifts in the abundance of grasses and woody plants in drylands have occurred several times during the Holocene. However, our understanding of the rates and dynamics of this state-change in recent decades is limited to scattered studies conducted at disparate spatial and temporal scales; the potential misperceptions of shrub cover change could be remedied using cross spatiotemporal scale analyses that link field observations, repeat ground-level photography and remote sensing perspectives. The study was conducted across a semi-arid landscape in southern Arizona. Local data from long-term transects revealed three distinct chronological phases of shrub cover change: expansion (1961-1991, 0.7% y
