More Bad News If You're a Fish: Mountaintop Removal Is Not Good For You


Although I’ve never been a sport fisherman, one of the things I remember from growing up in West Virginia was the enthusiasm so many of my friends and neighbors had for fishing. Lake fishing and trout fishing were a big deal, with lots of folks out on their boats or standing in their waders waiting for that next strike.
            Well, there is some new research out that demonstrates that mountaintop removal jeopardizes this pastime. Rivers and streams affected by mountaintop mining have only about a third as many fish as rivers and streams that have not been affected by the massive mining technique. Affected streams also have fewer than half as many species of fish than unaffected streams. These are the findings of research conducted by the U.S. Geological Survey. The title of the paper, published this week in the journal Freshwater Science, is Temporal changes in taxonomic and functional diversity of fish assemblages downstream from mountaintop mining.
            Some of the data used in the study was collected between 1999 and 2001 by a team from Pennsylvania State University. The USGS collected data for the study from 2010 to 2011. Other recent research had also found fish populations to be negatively affected by mountaintop removal.[i] And still other research found a link between the surface mining of coal and the extirpation of stream benthic organisms.[ii] To me, this research just points out the obvious. Anybody who has spent time around the sulfurous streams around surface mines will tell you that you won’t find many fish in them, and sometimes not much other life, either.
            As with other studies, this scientific work found heightened levels of selenium in the mining affected streams. Previous research, mandated by state legislation in West Virginia, found that high levels of selenium in streams were associated with deformities of fish larvae. In streams with especially high levels of selenium up to 20 percent of some fish species had deformities. This research dovetails with the USGS findings. If a lot of your offspring have deformities, a lot of those deformed offspring will not make it to maturity.
            How much more research is needed to convince people that mountaintop removal is harmful? I fear that nothing besides the depletion of all the viable coal seam in Appalachia will bring about the end to large coal companies blowing up our beautiful mountains. The paper’s press release from the USGS is here. And a hat tip to Ken Ward and his Coal Tattoo blog where I found out about this scientific study.

Scientists Discover That Mountaintop Removal Is Bad For Fish


One of the best things you can do in West Virginia is fish. I did some as a little boy, catching mostly bluegill in a lake not far from our home in Anmoore, West Virginia, and my uncle went often up to Elkins for some great fishing up around that area. Mountaintop removal, however, could be removing those fish from the rivers and streams of Appalachia.
            A new study[i] from the peer-reviewed journal Ecology of Freshwater Fish finds that mountaintop removal threatens the fish in the stream of Appalachia. Robert L. Hopkins, assistant professor of biology at the University of Rio Grande, and Jordan C. Roush of the U.S. Department of Agriculture, Natural Resources Conservation Service, studied the effects that mountaintop mining had on six different fish species that live in different stream ecologies in eastern Kentucky. Unsurprisingly, the scientists found that populations of four of the species were negatively affected by the existence of mountaintop removal in their streams’ watershed. Perhaps surprisingly, the study found that the effect of mountaintop removal was less dependent on the overall acreage of land destroyed by mountaintop mining in a watershed and was affected more by how large the individual mining operations were.
            Effects of Mountaintop Mining on Fish Distributions in Central Appalachia has just been published, so I only have access to the abstract. I don’t even know what kinds of fish or which watersheds were included were in the study. I will update this post as I learn more.
