Trees are bioindicators of global climate change and regional urbanization, but available monitoring tools are ineffective for fine-scale observation of many species. Using six accelerometers mounted on two urban ash trees (Fraxinus americana), we looked at high-frequency tree vibrations, or change in periodicity of tree sway as a proxy for mass changes, to infer seasonal patterns of flowering and foliage (phenophases). We compared accelerometer-estimated phenophases to those derived from digital repeat photography using Green Chromatic Coordinates (GCC) and visual observation of phenophases defined by the USA National Phenology Network (NPN). We also drew comparisons between two commercial accelerometers and assessed...

FY2013Shrub-dominated ecosystems of the Great Basin are being threatened by disturbances, typically wildfire followed by encroachment of invasive plants (e.g., cheat grass). To mitigate these threats and future changes in the climate to big sagebrush (Artemisia tridentata), restorationists require a knowledge base and tools to inform them of the most appropriate seed sources to plant to greatly enhance the success of restoration under contemporary and future climates. We propose to develop climate-responsive seed transfer zones based on associating plant quantitative traits and ecophysiological data from common gardens to the climate of the seed source.

The sagebrush steppe is a patchwork of species and subspecies occupying distinctenvironmental niches across the intermountain regions of western North America. These ecosystems facedegradation from disturbances and exotic weeds. Using sagebrush seed that is matched to its appropriateniche is a critical component to successful restoration, improving habitat for the threatened greater sage-grouse and other species. The need for restoration is greatest in basin habitats composed of two subspecies:diploid basin big sagebrush (A. tridentatasubsp.tridentata) and tetraploid Wyoming big sagebrush (subsp.wyomingensis). In this study we assess seed weights across five subspecies-cytotype groups of bigsagebrush and examine...
