Type: Oral Presentation Session: Network Analysis
Track: Tree-ring network analysis
The Fire and Climate Synthesis (FACS) project is a collaboration of about 50 fire ecologists to compile and synthesize fire and climate data for western North America. We have compiled nearly 900 multi-century fire-scar based fire histories from the western United States, Canada, and Mexico. The resulting tree-ring based fire history is the largest and most spatially extensive in the world, consis ... More

Type: Oral Presentation Session: Network Analysis
Track: Tree-ring network analysis
A network of ten ring-width chronologies of Pinus hartwegii a treeline species was developed from conifer stands at the Eastern Sierra Madre (ESM) and the Trans-Mexican Volcanic Belt (TVB) in the Valley of Mexico where the species was present. The PCA grouped the chronologies into two main components, PC1 for TVB and PC2 for ESM chronologies. ENSO in its warm phase (El Niño) and cold phase (La Ni ... More

Type: Oral Presentation Session: Network Analysis
Track: Tree-ring network analysis
Dendroclimatic analyses are being conducted on over 200 tree-ring width and density chronologies collected from subalpine fir (Abies lasiocarpa), mountain hemlock (Tsuga mertensiana), and white spruce ( Picea glauca) trees from high elevation sites located throughout the Coast Mountains of British Columbia, Canada. The data are assessed to evaluate spatiotemporal variability in the strength and na ... More

Type: Oral Presentation Session: Network Analysis
Track: Tree-ring network analysis
We introduce a novel data set, with unparalleled spatial density, for use as climate proxy data. A subset of ~500 Douglas-fir and pinyon pine tree-ring series collected on a systematic sampling grid by the Forest Inventory and Analysis Program (FIA data) were tested to determine their feasibility as climate proxies. First, we found strong temporal coherence between the FIA data and previously publ ... More
