Many tree species live for thousands of years, most for hundreds. Growing them will sequester a lot of carbon. Plus the soils in mature forest will sequester more. The amount of carbon you could sequester in a mature redwood, or fir forest is huge. In climates where these tree wont grow, oaks often will and can capture a lot of carbon and live for millennia. I would be interested on where you got the idea that trees are not a good way to sequester carbon (ref to a paper?).
