The Street Tree Selector uses the site conditions you describe to provide you with a list of trees that will grow well in that site. The Street Tree Selector focuses on the limiting site factors typical of urban sites--soil compaction, limited rooting space, pH, etc.--to narrow species choices to trees that will really grow in your site.
Therefore your first search page will ask you for common details such as soil pH, area, and compaction level. These factors are usually the most limiting for selecting trees. Then you can refine your search based on the other requirements of your site. If you are unsure of some conditions or requirements, select •any•. You can always refine your search later on. The Street Tree Selector uses the various criteria you enter, plus algorithms related to soil volume, compaction, the ultimate reasonable size of each species in an urban setting, and other criteria to generate a list of trees. Reduced soil volume is the factor that will eliminate the most species choices. If possible, use the techniques in Modify your Site to enlarge soil volume.
The more familiar you are with your site conditions, the more effective your search will be. If you are unsure of soil drainage, for example, this may unnecessarily restrict your search to trees that will tolerate the worst case scenario. If you are unsure of the site conditions, we recommend that you conduct a site analysis. See our Site Evaluation page for more details. After conducting a site analysis you may wish to modify your site instead of matching a tree to it.
