What are exotic trees?
What are exotic tree species? Exotic tree species are species introduced to an area where they do not occur naturally. Such species must initially be planted, but may be able to regenerate naturally later.
What are the advantages of exotic trees?
Benefits of Using Exotic Species
In general, exotic species have growing rates much greater than native species; therefore, they produce more wood per unit of area and time. In the tropics, exotic species could grow 5 to 10 times more wood than native species.
Why are indigenous trees important?
Planting indigenous trees can improve the soil quality and can increase the water retention of the soil, therefore decreasing soil runoff and reducing ocean pollution. 2. Trees provide shelter and food for wildlife such as birds, squirrels and insects.
How can plants be identified?

Shape is a better indicator than size, since individual shrubs can vary in leaf size. There are three basic leaf shapes, excluding those of conifers: lobed, smooth, and toothed. Lobed leaves have curvy or forked edges, such as oak leaves, while toothed leaves have many small teeth along the edges.
Is there an app to identify trees?
Leafsnap is a new free app that identifies trees. Go for a walk, take a shot of a leaf and this little wonder will identify its tree and give all kinds of information about it. The app is a result of a collaboration between Columbia University, the University of Maryland and the Smithsonian Institution.

How can you tell a perennial from a leaf?
Look at the base of the leaf, and if there is a bud there, it is a simple leaf. If you find the bud at the base of a grouping of leaves, they are compound leaves. Next, look at how leaves are positioned in relation to each other. If leaves occur in pairs directly opposite each other, they are called opposite leaves.
Is there an app to identify leaves?
Plantifier. Free on Android and iOS. This crowdsourced plant recognition app allows you to upload an image of an unknown plant; the users of the MyGarden.org community attempt to identify the plant and answer questions.
