Well, being 24 and having gone through the system myself, I think I should give some input.
It seems like everyone is just throwing programs out from every state in the Union. I think a more practical approach is to see what geographic areas he's okay with sending his daughter.
She's in high school looking to start as an undergrad right? Most likely, the best state school in your state will suffice because all schools have majors in biology, and possibly some type of environmental science. Only if the school is compellingly good would I rationalize going out of state and paying the extra fees.
Then, when the end of undergrad is near you can investigate appropriate graduate programs. In other words, you shouldnt go to an undergraduate school just becuase its grad programs are good. The undergraduate and graduate programs have different curricula and tap into different resources, and the students live very different lives. You should realize that graduate schools accept students from all over the nation anyway.
For undergrad, the better factors to consider are the quality of life on campus (housing, costs, food, diversity, size, campus beauty, student morale, and especially facilities).
Most people may think they know what to do at that age, but things can change. Therefore, I think spending time in a large college away from home (in other words, living in the college town and not going to a commuter school) is a good way to explore oneself and try to get some direction. At least that's how my alma mater helped me.
In today's America, graduate study is mandatory to get any worthwhile job. My peers all agree at how fun, but how useless undergrad is today with respect to job searches. About 3/4 of my friends are pursuing or want to pursue some type of post-undergrad education.
If you're still looking for names of grad schools, PM me and let me know, as I'm investigating environmental grad schools myself.
