Question

The procedure :

Follow steps 1-5 to calculate the previous values for South Florida trecere 11-1. Tree heights, trunk diameters, and ages are provided. Record your calcula- tions in Table 11-2. NOTES 1. Determining total weight of the tree The following algorithm for calculating the total weight of a tree is based on the tree species in the Southeastern United States. W = Aboveground weight of the tree in pounds D = Diameter of the trunk in inches H = Height of the tree in feet For trees with D < 11, W = 0.25D2H For trees with D2 11, W = 0.15DPH The root system of the plant weighs about 20% of the aboveground weight. Multiply the aboveground weight by 120% in order to determine the total weight of the tree. 2. Determining the dry weight of the tree The average tree is 72.5% dry matter and 27.5% moisture. To determine the dry weight of the tree, multiple the total weight of the tree by 72.5%. 3. Determining the weight of carbon in the tree On average, a tree's carbon content is roughly 50% of the total volume of the tree. Multiply the tree's dry weight by 50% in order to find out the weight of carbon in the tree. 4. Determining the weight of CO, sequestered in the tree CO, is composed of one carbon molecule and two oxygen molecules. The atomic weight of carbon = 12.0107 The atomic weight of oxygen = 15.9994 Therefore, the atomic weight of Co, is C + (20) = 12.0107 + (2 x 15.9994) = 43.9987 The ratio of CO, to C comes then from the ratio of atomic weights: 43.9987/12.0107 = 3.6633 Therefore, to determine the weight of carbon dioxide sequestered in the tree, multiply the weight of carbon in the tree by 3.6633. 5. Determining the weight of CO, sequestered in the tree per year To determine how much CO, has been sequestered by the tree each year, divide the weight of CO, sequestered in the tree by the age of the tree.

The question :

Answer 1

Since you have not provided a personal carbon footprint, I have myself calculated the carbon footprint . The calculation is based on estimates of travel by train ,subway and air, use of natural for cooking, use of petrol for car travel, and electricity consumption.

The carbon footprint estimate for 1 year is 11331.87 pounds.

Tree	Weight of CO2 sequestered per year	Number of Trees needed to Offset Personal C Footprint	Ideal area needed per tree (in ft2)	Total area needed (in ft2 )
Delonix regia	866.0217	13.084	2500	32710
Quercus virginiana	1,201.2388	9.433	5625	53060.625
Swietenia mahagoni	504.1870	22.475	900	20227.50
Bucida buceras	135.9769	83.33	1600	133328
Sabal palmetto	468.3061	24.1975	100	2419.75

Calculation of no. of trees required offset personal carbon footprint = Personal Carbon Footprint in a year / CO2 sequestered by that tree per year.

Applying this formula, the number of trees for each species has been calculated.

Calculation of total area needed = No. of trees required to offset personal carbon footprint * Ideal area needed per tree.

Using this formula, the total area needed has been calculated.

3. The species Sabal palmetto would be the ideal tree and the best to plant since it occupies the least space in comparison to other 4 trees and also offsets the personal carbon footprint.

4. When compared to the personal carbon footprint, the land area required by Bucida buceras is highest with 83 trees to be planted in an area of a whopping 133328 ft2 area.Sabal palmetto needs the least area of 2419.75 ft2 with 24 trees to be planted. Quercus virginiana is the second in line when compared to total area needed to offset the carbon footprint (53060.625 ft2). The descending order of area needed to offset the personal carbon footprint is as follows :

Bucida buceras> Quercus virginiana > Delonix regia > Swietenia mahagoni > Sabal palmetto.
