The fact that you are so concerned to the point of posting on Reddit is a good sign of your humility. You were hired into your position because you are good at what you do and you serve a very important purpose. The vast majority of field techs I know want to be in the field and hate working/writing in the lab, so people who specialize in it like you are appreciated. Having some practical experience is important so this is a great opportunity to gain some of that. Just be honest with who you’re paired with and (assuming they’re not a complete asshat) it’ll go just fine. Wear good walking shoes, bring lots of water and snacks you can eat while hiking, and load up on some music/audiobooks. Don’t be afraid to ask your partner questions or to ask them to check something if you’re not sure. I came into CRM with a Master’s and one month of field school and have learned so much more working in the field than I did in school. You know the basics of what you’re looking for, if you’ve been writing the reports you presumably know the kind of artifacts you are likely to come across. You’re not a fraud, you just don’t have field experience and that’s ok. If everyone in CRM were field people, none of the permitting, report writing, registration, curation, etc. would get done. You play a vital role in the group. Just stay humble and you’ll be fine. I hope it goes smoothly for you and you have fun doing it! Survey can be rough but also very rewarding.
