Anyone know what uniform this man is wearing?

Thank-you very much for your help in this. So he is Forestry then? I don't see an exact example of the collar insignia on your website.

I was pointing out that this isn't a forester, that's why i quoted my website so you could see for yourself.
my best guess is a member of a schutzenverband. But this is a guess

In older uniform-regulations from forestry from about 1926 (up to 1934)
the single oakleaf was anyway in use, in a form like the shown one. It was
sewn directly onto the collar. Collar patches came with a later date! .

Here is the proof it is forestry. Such oakleaf is worn by various men
from the Forstschule at Reichstadt, which is now in Tsjech.
