I had an offer for thids course too, i thinks its a pretty good course it was highly recomended by one of my tutors who had taken this some years before.
I got the general feel that its the normal jobs such as conservation/biodiversity officers and managers. but i guess you could get into goverment jobs like DEFRA or just working for localised organisations like regional workers for natural england and stuff. The course is meant to be highly practical based to give the opportunities to ppl who are lacking in relevant work experience and also your final year project can add to this - if you hold a driving lisece my teacher said some of the project you could undertake are amazing.
i guess with all of these types of jobs though even with a master, most of us will have to start right at the bottom of the rung and gradually work our way up!
unfortunatly i have just been offered a place at imperial, otherwise i would have been joining you!
good luck with it anyway
