There are many colleges that offer wildlife-conservation degrees. For example, Ohio State offers a degree in Forestry, Fisheries, and Wildlife (within their School of Environment and Natural Resources). I went to Michigan State for my first fish & wildlife degree.
While many colleges do offer conservatoin degrees, some programs are more 'sciencey' and others are more 'management' oriented. Some college conservation programs are in Biological Science departments while other universities have them in schools of Agriculture (which often include Forestry or Range Management departments). The first kind of college focuses on 'natural science' (zoology, ecology) while the latter considers wildlife as 'natural resource' management.
The coursework is largely the same, but the natural-science path focuses more on environmental issues, lab ecology, and the ecology of animals around the world. (For example, if you're interested in the tropics or ecological work in other countries, a natural-science degree might be better.) If you're more interested in hunting and fishing, or working for a state or federal agency, then the natural-resource approach may be better.
And you could minor in journalism, or at least take a couple journalism courses as 'elective' classes while you pursue a wildlife degree. I know several folks that have done just that. For that matter, you don't need a degree to write stories - you can start now and try submitting them to some conservation magazines.
I hope this helps some.
