Nitrogen-fixing trees will help build soil and most bear blossoms that attract
insects. In Egypt, these include Erythrina indica, Cassia nodosa, Delonex regia,
Jacaranda ovalifola and Albizia lebbeck. The canopy trees will describe the chief
patterns of the forest garden, thus they necessity be chosen wisely. Plant them with
careful in respect to their expected final size so enough light will fall among all aboveground tree parts [138]. Most Important Street Trees According to Their Efficiency
for Reducing Carbon Dioxide from Atmosphere.

Table 2 shows the role of Egyptian street trees in reducing carbon emissions or
absorbing carbon dioxide from the surrounding air. The results deal with specific
leaf area, i.e. calculated for every 1000 cm
3 of one leaf surface only. It is better to
calculate the total leaf area of the entire tree. Because it is difficult to find different
trees in the same age at the same environmental conditions. Data in Table 1 and Fig. 6
show that Ficus religiosa trees are best in CO 2 uptake through the first 5 min after
