Trees aren't really carbon negative, but carbon neutral over an extended lifespan. They die and turn back into atmospheric CO2 (perhaps becoming even worse methane along the way) while their leaves continually do this over a short period.
But the trees usually do this over a timescale of 20-220 years (less when there are fires or climactic change), so are much better than nothing. But they don't count as "permanent".
