is a good place to start

I am also studying at Silwood currently on MSc ecology, evolution & conservation. I came straight from my BSc, so have no work experience in conservation. I think that as long as you get a solid 2:1 and a strong personal statement, you will have as good a chance as anyone else of getting in. It's good that you're older, as most people here are about 25 or older, and a lot do PhDs. I find Silwood can get lonely sometimes and it is remote. You really need a car in this area to have a fulfilling life (the nearest train station is a good 20-30 minute walk away in Sunningdale). EJ Milner-Gulland is my project supervisor. She's very good, very professional and helpful. But it's likely you will see a lot of other staff too, as EJ seems very busy, so have a look at the interests of other staff that are based at Silwood too. It's VERY QUIET here, if that's what you like, you'll love it, if not, don't come here!
