Once had a great mission and set of goals now reduced to fundraising and "policy change".
Pros: relaxed atmosphere, easy work environment
Cons: management change, focus towards fundraising forgoing the original goal of saving truly great places, job security
I have worked for The Nature Conservancy for over ten years off and on doing mostly seasonal fire work. It was a great place to work and learn until management changed a few years ago. Now there is a large focus on fundraising, government relations, and policy change.
This is in stark contrast from the on the ground conservation effort that was at the heart of The Nature Conservancy. I know people who had been employed by The Nature Conservancy for many years starting to leave in favor of a more true conservation minded organization. It is such a shame because it used to be such a rewarding place to work. In short if you are truly interested in real conservation work and "saving the best places on Earth" I would advise against The Nature Conservancy.
