hi hari
please told me what you want to know clearly.
if friend you are asking about life span of tree than it varies according to different species of trees.
if you are sking about tree of life then :The tree of life is a metaphor which expresses the idea that all life is related by common descent. Charles Darwin was the first to use this metaphor in modern biology. It had been used many times before for other purposes. The evolutionary tree shows the relationships among various biological groups.
