TREE LEAF GUIDE PICTURES FULL
While there is typically a recognizable pattern and some distinctive characteristics common across all leaves on the same plant, certain species (typically within the same genus) can have very similar leaf characteristics, making it possible for a single plant to have individual leaves in its canopy which are distinctive of its true species and other leaves that would lead you to believe its another, similar-looking species.Ī good example of confusing similarity would be white oak (Quercus alba), bur oak (Quercus macrocarpa) and swamp white oak (Quercus bicolor), whose leaves can have a very similar or very different pattern of lobes based on where you look in the canopy of an individual plant. Shade leaves, or leaves on the interior of the canopy, are often larger with more distinct lobes than leaves in full sun. To me, it is extraordinary that these apps are even able to process visual data and generate near accurate results. As a trained botanist, I know that 2 leaves for the same tree can often vary widely.
TREE LEAF GUIDE PICTURES SOFTWARE
Researchers with the Rutgers Urban Forestry Program designed and implement this study which assessed the apps’ abilities to identify photos of 55 common street trees and native forest trees in New Jersey.įor their study, experienced arborists photographed both bark and leaves of trees and submitted their photos to the 6 most commonly downloaded plant identification apps based on downloads from the Apple App Store® in June of 2020. The specific apps assessed include: iNaturalist™, PlantNet™, Leafsnap™, PlantSnap™, PictureThis™, and Plant Identification™.Īt least 4 images of both bark and leaves for each tree species were submitted to each app and researchers observed and recorded the results. The apps use photo recognition software programmed to identify leaves and bark based on the common characteristics of these plant parts. These apps boast their accuracy and many claim to provide identification for a wide array of species simply based on an image of the foliage. Do these apps work? And, if so, how accurate can they be? Research on phone app accuracyĪ research paper published in the most recent edition of the scientific journal, “Arboriculture and Urban Forestry”, explored the accuracy of photo-based plant identification apps. In recent years, photo-based smart phone applications (apps) have been developed to aid with plant identification in the field.
There are tons of terms to learn and understand just to start identifying plants by leaves and other plant parts. Throw in a leafless winter, and it makes for a difficult skill to develop with confidence. Plant identification can be incredibly challenging for beginning botanists or even experienced plant people.
