On impact of experimental time of mangrove forest relative abundance in the absence of Artisinal hydrocarbon effect

Abstract

An impact study of experimental time of mangrove forest relative abundance in the absence of artisanal hydrocarbon effect has been investigated. The analytical solutions of tree growth mod- els were derived and used to predict the impact of experimental time of mangrove forest relative abundance through computational method using MATLAB ODE45. Three different mangrove
sites in the Niger delta and considered as natural mangrove forest vegetation sites in the absence of artisanal hydrocarbon. It is observed that on the based day of our experimental time called the initial condition, the relative abundance of the three sites was recorded as 0.01 units, same values each. Furthermore, from the tenth month up to the one hundred and twentieth month, the data base result shows a monotonic increasing pattern in the relative abundance of the three coordinates as 0.0246 units on the tenth month to a saturating value of 0.2427 units on the one hundred and twentieth months. These observations show a strong increase in the numerical strength of the relative abundance of the second coordinate followed by the first coordinate with a slow increase in numerical strength and a strong increase pattern in the third coordinate which converges earlier to its saturated value.
