Hi there Adekunle,I do believe the name of the person you're looking for is a Botanist.The tricky part is to narrow it down,because there are also Field Biologiststhat Specialize in Forestry.I'm from Canada,and there are so many opportunitiesin the Forestry Field that the study of Reforestation is big Business.Have I now completely confused you?,if I have,then I've done my job.LOL!
