Professional qualification: it's your job title.
As a fresh graduate, there should be no professional title.
Just write: forestry undergraduate course, but don't be too blind.
The title didn't come until after you worked, so we can take the forestry engineer exam.
I suggest you call this forestry bureau to ask. Writing by yourself is risky and welcome.
This year is the year of economic crisis. As a forestry student, I wish you success in your job search!
