What are the advantages of exotic trees?

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?

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.

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?
