climate change implicatations for biodiveristy hotspots
Davies, P. M. (2010), Climate Change Implications for River Restoration in Global Biodiversity Hotspots. Restoration Ecology, 18: 261–268. doi: 10.1111/j.1526-100X.2009.00648.x
The author uses global biodiversity hotspot of Southwestern Australia as an example of potential restoration responses to climate change in other global biodiversity hotspots. The author finds that most biodiversity hotspots will experience warming, and most are geographically restricted. The author recommends “over restoration” or revegetation of the riparian area, as a means to help lessen the impact of climate change and help maintain the existing vegetation condition, and keep the streams cool.
While using revegetation as a dampening effect to climate change makes sense, I wonder how practical it will be as temperatures rise. In our current condition, there are many failed (or failing) restoration sites due to lack of maintenance of plants once they are installed. It seems the first implication of this study is that we need a greater understanding of the importance of irrigation and maintenance of plants post installation.
