It’s far from comprehensive but it’s probably representative — and we can extend it and refine it as we work. The new list supersedes a much smaller one that was simply a record of which species we had thus far managed to propagate. The old list was not developed as a project in its own right, nor was it a tool for directing our propagation work. We created the new list with the help of two key witness

Leaf 9: Is the Tree Bank Helping to Slow Climate Change?

A leaf from: This Broken Land of Promise: A Chronicle of Conservation in the Hispaniolan Border Country I see this as an unavoidable question, given the nature of our work and the era in which we live. My short answer is yes. We plant thousands of trees every year on lands that are mostly deforested, so we are increasing the amount of carbon stored in those lands. This happens because the trees absorb carbon dioxide from the atmosphere as they grow. So far, so good. Next question: are tree-planting programs a remedy for climate change?
