Putting aside any quips about how our oil fields used to be part of the biosphere, I do think the current view is that forests are net carbon sinks, even accounting for decomposition. Regardless, the time scale for growing and decomposing a forest is enormous and would buy a lot of flexibility in solving the problem more permanently if additional research shows them to not be efficient sinks long-term.
