The job opportunities for ecologists are just as good as they are for other working stiffs -- that is, merely OK. But as long as buildings are being built and fires are burning them down, there will always be a need for ecologists. The best prospects belong to the folks who have the academic degrees and skills. In fact, a big growth area in the world of ecology is range management. The "rangers" are the ecologists who move in after a natural disaster has leveled an area to see how bad the damage is. It's something like being an environmental undertaker.
