Dr. Stuart also leads a lively discussion on the role of ecosystem restoration in our rapidly changing climate change impacted ecology. As ecosystems rapidly develop globally influenced by both introduced species and anthropogenic climate change, he discusses whether there exist any ecosystems globally that are not human impacted. He discusses whether all existing ecosystems are in fact "novel" ecosystems.
Dr. Stuart explains how historically many ecosystem restoration projects are based on returning an ecosystem to a non-anthropogenically impacted baseline. Yet defining what these baselines are inherently difficult. For example Nachusa Grasslands in north-central Illinois, USA, is a 3,000 acre prairie, savanna, and wetlands mosaic ecosystem restoration project. Dr. Stuart shows us how the decision to "benchmark" the ecosystem restoration baseline to the year 1800 is a human-based decision, and in fact, the Nachusa Grasslands may have been anthropogenically impacted in the year 1800. Furthermore, portions of Nachusa Grasslands have been restored to from 48 to 150+ original species. Given this range of restoration, can we label a prairie restored to 48 species as a restored original ecosystem? Or do we need to restore each acre portion of restored prairie to 150+ original species to complete an ecosystem restoration project?
This question is pertinent in light of the recent impact of Superstorm Sandy on many US Wildlife Refuges. How much ecosystem restoration should we do to the obviously anthropogenically-impacted US Wildlife Refuges impacted by Superstorm Sandy? At what point, can national wildlife refuge managers conclude an ecosystem restoration project? How will we measure the ecosystem restoration criteria for these impacted wildlife refuges? These questions require ecosystem restoration frameworks that will require budgeting and measuring and monitoring benchmarks. Answering these questions can be facilitated by the knowledge and processes described in Dr. Stuart’s Ecological Restoration and Environmental Change: Renewing Damaged Ecosystems.
Ecological Restoration and Environmental Change: Renewing Damaged Ecosystems is filled with excellent easy-to-read case studies that provide good background information for both the academic and the student. Whether someone has a casual interest in the human decision-making ethics surrounding ecological restoration, someone needs to manage an ecosystem restoration budget, or someone is a natural resource scientist, Ecological Restoration and Environmental Change: Renewing Damaged Ecosystems is a must-have addition to their professional library.

Putting people to work: restoring our ecosystems, sequestering carbon
(10/02/2011) President Obama's sole focus of his September 8th speech to the United States Congress was job creation. He closed his speech by summoning an earlier time of promise: "President Kennedy once said, ' Our problems are man-made—therefore they can be solved by man. And man can be as big as he wants.' These are difficult years for our country. But we are Americans. We are tougher than the times we live in, and we are bigger than our politics have been. So let's meet the moment. Let's get to work..." Inspiration is surely needed because in addition to the United States, where unemployment remains at about 9 percent, severe unemployment is found throughout the world, with Greece, Spain, and South Africa, for example, having 2011 summer unemployment rates at over 16, 20, and 25 percent, respectively.
