My Tree ID, developed by Texas A&M Forest Service, facilitates tree species identification based on leaves, flowers, seed, bark or location using a key, descriptions, and tree images. It contains over 1500 images from 475 different tree species and includes known occurrence maps from the Biota of North America Program for nearly all species. Individual tree detail pages have complete descriptions including interesting facts and similar species. The map feature allows users to input an address, select current location, or click on any point on the map to narrow the list. A full glossary and a tree age estimator tool complement the key and species list.
There are two ways to search for species. One, a simple key by characteristics directed approach, allows users to select one or more tree characteristics from large color icons. At any point in the process the possible species may be displayed. The other way is to select certain filters from the A-Z species list. The filter tool can also narrow down possible choices at any stage in the keying process. The species list is searchable by common or scientific name, or simply alphabetically.
Designed to be an educational tool for anyone wanting to increase their understanding of trees, simple language and terms are used throughout the app whenever possible. More technical terms can be defined in a pop-up window by selecting the highlighted word. Users may also refer to the full glossary at any time without losing their place in the process.
The tree estimator tool uses a species growth factor and tree diameter to provide a rough approximation of tree age. The app uses published growth factors and only a limited number are available. However, this serves as a starting point for estimating individual tree age.
