Few finer days exist beyond those spent keying out willows. Much of John’s time doing so has been in association with his work restoring Colorado’s riparian areas—from alpine to plains. After 18 years of experience in Ecological Restoration, John pays homage still to the insights his knowledge of native flora provide into the fun little secrets of ecological restoration. Enjoying membership in CoNPS for 16 years, and serving as a board member for two years, John enjoys steering budding restoration ecologists to the society for a lesson or two. Today, somewhere between the botanizing and the restoration work, he is pleasantly busy growing the Southern Rockies Seed Network, a seminal program of Synergy Ecological Restoration.
