Variable General Info

Name variable.detail.varNameHelp ?	Hardiness zone ? Comment: Information on hardiness zones was derived from the Horticopia database and based on USDA hardiness zones. For zones with a decimal rating (e.g., 4.5), values were rounded down for maximum hardiness (e.g., 4) and up for minimum hardiness zone (e.g., 5). Species are noted as to the reliability of the hardiness zone data with increasing number of asterisks indicating an increasing degree of uncertainty. One asterisk (): some uncertainty regarding hardiness zone; two asterisks (): moderate uncertainty regarding hardiness zone; three asterisks (**): high uncertainty regarding hardiness zone. Estimates derived from Dirr (M.A. Dirr, 1975, Manual of Woody Landscape Plants. Stipes, Champaign, IL. 1007 p.) and Sunset (1985, New Western Garden Book. Lane, Menlo Park, CA. 512 p.). As hardiness estimates or maps did not always exactly match USDA Hardiness zone ranges, some extrapolations were made to the closest hardiness zone.	Invasive tree species (y/n) ? Comment: Tree species identified as invasive or not.	Pest risk of tree species ? Comment: Possible pests affecting the tree species are reported.	Pollutant sensitivity of tree species ? Comment: Indicates sensitivity to the pollutants; ozone, nitrogen dioxide, and sulfur dioxide. "S" indicates sensitive to pollutant; "I" indicates intermediate rating between sensitive and tolerant to pollutant; and "S/I" indicates a mix of sensitive and intermediate ratings in the literature.	Tree species ? Comment: Based on user-supplied information of location (city and state), and minimum and maximum tree height desired, the database is reduced to only tree species that are hardy to the hardiness zone of the location and that are larger than the minimum tree height and smaller than the maximum tree height specified (based on median tree height at maturity). Species are noted as to the reliability of the hardiness zone data with increasing number of asterisks indicating an increasing degree of uncertainty (see Hardiness Zone above). The user is also asked to rate the importance of each tree function on a scale of 0 (not important) to 10 (very important). The program weights the standardized functional values by the corresponding user-supplied value, sums the weighted values for all functions, and standardizes the sum values on a range between 0 (minimum value) and 100 (maximum values). The program then provides output of species recommendations in 10% groupings. These groupings are to be used to make decisions on the most appropriate species for an area given the desired tree functions. Actual decisions on what trees to plant in the area need to incorporate local knowledge of species and conditions to ensure that the proper species is selected to ensure long-term survival, health, and environmental services.
