Hi! One area that'll snap you up and pay well is environmental consultancy. Basically if you can ID a group of animals - insects/inverts are the best group you will be sitting happily. I believe a consultant is paid about £500 a pay to study a field or whatever and survey it to assess what species are in it and the potential environmental damage caused by a development. In particular if you can ID freshwater inverts and plants you will get snapped up for sure - very few people can ID them and you will examine the creatures in a river to observe its health, etc.
Basically a company will pay you a stupid amount to go and walk around identifying butterflies and whatnot to see if they can build a house there or not. And there are marine companies that also do this, though they are harder to get into. You could also look at doing park ranger work in the US or Canada
If it's of interest I'm doing Ecology and Wildlife Conservation but plan to go into the wildlife guiding/whale-watching industry. And I need a lot of experience (I've already done some and it is so rewarding! And I've just spent 3 weeks guiding in British Columbia at a whale watching camp and it was fantastic!) but it allows me to watch whales, dolphins and sea life, talk to people about it and collect important research/data on cetaceans - data that is typically very expensive to collect. It also allows me to travel. If it's of interest you can do a 1 year bush safari guide course - on completion, most people do get hired as safari guides! And again, you do learn how to collect data on the wildlife. This course is £10,000 and it's now an actual requirement of the African safari companies that safari guides have this qualification.
Again if you aim to go into surveys, you will need ID skills - get out and learn to ID your birds and learn your insects, etc. And plants - even less people can ID plants, so if you can ID plants you'll be set! Also get qualifications regarding animal handling so great crested newt licence, dormouse, adder licences - you'll stand out. And yes, a ranger here can earn about £20,000 a year I think.
