“It depends on the tree’s species and age, but a mature, healthy tree can have 200,000 leaves. During 60 years of life, such a tree would grow and shed 3,600 pounds of leaves.” Now you know too !!May 29, 2016.
How do you calculate the number of leaves on a tree?
To estimate the approximate number of leaves and the total leaf area of a deciduous tree, count the number of leaves on one twig. Estimate the number of twigs on a branch and the number of branches, then multiply these numbers together to get the (rough) total number of leaves (see below).

How do you calculate the number of leaves?
Calculate the number of leaves per unit area (spreading them closely like a jig-saw puzzle). Find out the approximate diameter of the tree crown under study and find out the area and calculate the crown area. Multiply the crown area with the number of leaves per unit area.

Earth today supports more than 3 trillion trees—eight times as many as we thought a decade ago. But that number is rapidly shrinking, according to a global tree survey released today.
How many leaves does a poplar tree have?

How much weight do leaves add to a tree?
A leaf weighs between 1 and 5g where 5g is for a big leaf like a horse chestnut so if you multiply 5g by 177 000 you get about 1 tonne, about the same as a small family car, not a huge weight as the wood of the tree will weigh a lot more than this.

What are the types of leaves?
There are two different types of leaves – simples leaves and compound leaves. The other types of leaves include acicular, linear, lanceolate, orbicular, elliptical, oblique, centric cordate, etc. They perform the function of photosynthesis and help in the removal of excess water from the aerial parts of the plant.

What is total leaf area?
LAI is a measure for the total area of leaves per unit ground area and directly related to the amount of light that can be intercepted by plants. It is an important variable used to predict photosynthetic primary production, evapotranspiration and as a reference tool for crop growth.
How do you calculate the total leaf of a plant?
Leaf area (A) can be simply calculated by multiplying the product of leaf length (L) and width (W) by a constant (i.e., the Montgomery parameter; MP).
