Last year I reported the 2008 ISI Impact Factors for some prominent conservation journals and a few other journals occasionally publishing conservation-related material. ISI just released the 2009 Impact Factors, so I’ll do the same again this year, and add some general ecology journals as well. For all you Australians, I also recently reported the ERA Journal Rankings.
So here are the 2009 Impact Factors for the journals listed on this site’s Journals page and their 2008 values for comparison:
- Animal Conservation: 2.358 (2009) versus 2.587 (2008)
- Biodiversity and Conservation: 2.066 (2009) versus 1.473 (2008)
- Biological Conservation: 3.167 (2009) versus 3.566 (2007)
- Conservation Biology: 4.666 (2009) versus 4.705 (2008)
- Conservation Evidence: no Impact Factor yet
- Conservation Letters: not yet old enough to obtain an impact factor, but one should be ascribed in 2011
- Conservation Genetics: 1.849 (2009) versus 2.408 (2008)
- Diversity and Distributions: 4.224 (2009) versus 3.466 (2008)
- Environmental Conservation: 1.541(2009) versus 1.875 (2008)
- Frontiers in Ecology and the Environment: 6.922 (2009) versus 5.065 (2008)
- Global Change Biology: 5.561 (2009) versus 5.876 (2008)
- Journal for Nature Conservation: 0.711(2009) versus 0.940 (2008)
- Oryx: 1.693 (2009) versus 1.381 (2008)
and for some ecology journals that frequently publish conservation-related material:
- Ambio: 2.486 (2009) versus 2.092 (2008)
- Austral Ecology: 1.578 (2009) versus 1.826 (2008)
- Biotropica: 2.270 (2009) versus 2.170 (2008)
- Ecography: 4.385 (2009) versus 4.099 (2008)
- Ecological Applications: 3.672 (2009) versus 3.628 (2008)
- Ecology: 4.411 (2009) versus 4.874 (2008)
- Ecology Letters: 10.318 (2009) versus 9.392 (2008)
- Journal of Animal Ecology: 3.714 (2009) versus 4.222 (2008)
- Journal of Applied Ecology: 4.197 (2009) versus 4.560 (2008)
- Journal of Biogeography: 4.087 (2009) versus 4.566 (2008)
- Global Ecology and Biogeography: 5.913 (2009) versus 5.304 (2008)
- Marine Ecology Progress Series: 2.519 (2009) versus 2.631 (2008)
- Molecular Ecology: 5.960 (2009) versus 5.325 (2008)
- Oecologia: 3.192 (2009) versus 5.325 (2008)
- Wildlife Research:1.222 (2009) versus 1.111 (2008)
and for some more general journals that occasionally publish conservation papers:
- Nature: 34.480 (2009) versus 31.434 (2008)
- Proceedings of the National Academy of Sciences of the USA: 9.432 (2009) versus 9.380 (2008)
- Science: 29.747 (2008) versus 28.103 (2007)
- Trends in Ecology and Evolution: 11.564 (2009) versus 11.904 (2008)
Also rather cool, the new-ish Open Access journal, PLoS One has received its first Impact Factor and comes in at a respectable 4.351 (phew! – I’ve published two papers [see here and here] there in the last few years).

In fact you could. There are quite few countries where a list of numbers can be copyrighted. ISI’s stance on this is quite ridiculous. I’d love to get time to see them trying to so me. Note that (in my country at least), a phonebook can also not be copyrighted. The work needs to be creative for that.
But honestly, the list is useless anyway. Just use google and you get a number which means just as little, and can be more easily verified.
