The over-arching theme of this work is that soil data affect the performance and realism of vegetation models with particular focus on their ability to predict or explain disturbances such as fire or disease. We tested the sensitivity of the Excel version of the 3-PG model to soil properties and applied this information to understanding bark beetle attacks in drought-stressed forests. We tested the sensitivity of the MC2 model to soil depth with a particular focus on how soils affect the biogeochemistry and fire modules of the Dynamic Global Vegetation Model (DGVM). We found in these sensitivity analyses, soil depth, soil water storage capacity (ASW) and soil texture are among the most important soil factors to...

Ecological systems are already responding to modern changes in climate. Many species are moving in directions and at rates that correspond with recent climatic change. Understanding how species distributions and abundances are likely to be altered can inform management and planning activities resulting in more robust management. We projected climate-driven changes in the abundances and distributions of 31 focal bird species in Oregon and Washington using the latest downscaled CMIP5 climate projections and corresponding vegetation model outputs. We mapped these future projections and integrated them into an existing web-based tool (http://data.pointblue.org/apps/nwcsc/) to allow managers and planners to access and...
The rate of future climate change is likely to exceed the migration rates of most plant species. The replacement of dominant species by locally rare species may require decades, and extinctions may occur when plant species cannot migrate fast enough to escape the consequences of climate change. Such lags may impair ecosystem services, such as carbon sequestration and clean water production. Thus, to assess global change, simulation of plant migration and local vegetation change by dynamic global vegetation models (DGVMs) is critical, yet fraught with challenges. Global vegetation models cannot simulate all species, necessitating their aggregation into plant functional types (PFTs). Yet most PFTs encompass the full...
