Global Change Tree Atlas Questions

Questions answered by the Global Change Tree Atlas

FOR ANY OF THE 80 SPECIES,

Red Dot What is the current distribution of importance value (basal area and no. of stems of understory and overstory)? (Source: FIA and Little's Maps)

Red Dot How would this distribution change if climate (ie., temperature, precipitation and potential evapotranspiration) were to change according to 5 GCM climate change models? (GISS, GFDL, UKMO, Hadley & CCC)

Red Dot Which variables (among the 34 climatic, edaphic, topographic and land-use variables) are driving the distribution geographically?

Red Dot What are the life-history, regeneration and disturbance characteristics?

Red Dot What are the optimum ranges of certain important ecological attributes? (eg., temperature, precipitation, growth rate, elevation, slope, pH, permeability, water-holding capacity, etc.)

Red Dot Can we get a quantitative index for the changes in importance values, area, and north-south shifts according to different GCM climate change scenarios?

COMBINED OUTPUT OF 80 SPECIES:

Red Dot Can we predict how the forest types would change according to different GCM climate change scenarios compared to the current scenario?

Red Dot What would be the "5-GCM" average forest-type map be like? What is the level of agreement among GCMs with regard to forest-types?

Red Dot How can we obtain a county-level database of the many tree species occurring in the county, sorted by its importance value?
