Not sure I saw this first time around:If you want to leave a environmental legacy of your life giving your funds to purchase wildlands is a gift that will last for hundreds of years.
Everything else is really temporary in its impact.
Yes, there are lots of organizations that do excellent work, but it is not as important as the purchase of land and transfer into public ownership.
Ducks Unlimited, Pheasants Unlimited, Western Rivers, Nature Conservancy, Trust for Public Lands and others that purchase lands have a huge impact for hundreds of years.
It will be more important in the years to come. We have nowhere close, nor are the public lands well distributed to hold on to the ecosystems we have today.
Look at what we have lost in our lifetimes. It is staggering.
The problem with conservation easements is that they cost 90% of the purchase price. The Forest Service refused to do easements preferring to just do outside purchase. Congress has in some cases directed the Forest Service to buy easements instead of ownership.
Here is the perfect case study of the problem with conservation easements. For a 95 million dollars the taxpayers of California got a "NO TRESPASSING" sign.

JUST BUY IT.
The property in question is not necessarily conservationally important. For all we know it's a house and half acre of suburban lawn in the middle of a planned neighborhood.
Arranging to have it sold and the proceeds donated to a conservation org is more likely to be what most folks are asking about.
People still need homes
Just FYI, Western Rivers is one of my 501c's of choice
Mayfly Project is nationwide, but benefits foster kids, not environmental issues. The national office is happy to accept fly gear donations to be auctioned off to fund chapters!
