As far as plants go, Bristlecone pines found in the White Mountains in California, have the longest life span of any plant or tree. One such pine named the Methuselah tree is estimated to be 4,725 years old. If you consider clams as animals and not just ingredients for soup then the quahog clam has quite an impressive life span. In 2007 scientists found a quahog clam off the north coast of Iceland which they believe to be 400 years old.
Life Span. The Virginia Big Tree Program has compiled a list of common trees of the Americas and their life spans. The Balsam Poplar lives an average of 100 years and can live up to 150 years. The Yellow Poplar has a much longer life span at 250 years on average, and a maximum of 450 years.The Hybrid Poplar will only reach 30 to 50 years of age, a relatively short life span. It is primarily used for timber and harvested between six and 12 years old.hey can reach 20 feet high in just three years with a full mature height of 70 feet tall. The growth rate relation to life span shows promise in the case of the hybrid poplar, a rapid grower with a short life span.
