Sustainable Herbs Project- A wonderful body of articles and info tracing our beloved herbs back to their source. It has amazing information on what we can do as consumers, as herbalists and as teachers to protect these plants that we love and how to protect the farmers/wildcrafters who provide them.
United Plant Savers- A wonderful organization focused on the preservation of medicinal plants. Any herbalist will benefit from the list of at risk plants, in depth articles, and even how to create your own botanical sanctuary.
