Dear List Participants,
I would like to bring to your attention a new publication by
the United States Geological Survey: U.S. Geological Survey Professional Paper 1650-A and 1650-B
Atlas of relations between climatic parameters and distributions of important trees and shrubs in North America- Introduction and Conifers
Atlas of relations between climatic parameters and distributions of important trees and shrubs in North America-Hardwoods
These are wonderful publications. They reproduce the atlas maps originally available in Little's Atlas of Trees published in the 1970's. In addition are graphs and tables of climatic data associated with the species distribution. Such as:
Annual Precipitation vs. July Temperature
January Temperature vs. July Temperature
January Precipitation vs. July Precipitation
Mean Temperature of Coldest Month vs. Growing Degree days on 5 degree C
Actual Evaporation/Potential Evaporation
This publication will be of interest to any garden or arboretum involved in tree ecological or physiological research. This atlas will be must useful in obtaining a more complete concept of 'hardiness zones' as in includes other environmental factors influencing distribution other than winter temperature.
They are for sale ($63.00 USD) by the:
