I graduated with an environmental science degree 3 years ago. To be honest it would seem that a masters is not needed to get work. By all means if you enjoy education then go ahead but when it comes to a job you will not be given preferrential treatment over those without a masters. Experience is the key, some places will take on people that don't have huge amounts of experience, but obviously that is reflected in the pay but just keep perservering and you will climb the ladder.
My best possible advice is that flood the market with your cv, join employment agencies, professional bodies and call in all the favours you might be owed. Don't be nervous to ask just get out there and speak to everyone you can no matter whether you think your qualified or not.
its a common mistake that you have to work for free/volunteer to break into the ecology industry, perserverance is the key. Send your cv to companies, follow up with a telephone call a week later to check its recieved and show your enthusiasm for working for them, if called to interview no matter the post your going for dress to impress, chat to everyone including even the receptionist as quite often they are asked what they thought of you. Dont let the interviewer work to hard, talk to them dont wait to be questioned/prompted.
If all else fails then buy a lottery ticket and keep your fingers crossed
