An odd suggestion I know, but take a look at some bibles.  The King James Bible uses the word "kind" to describe different animals in Genesis 1:

²⁴ And God said, Let the earth bring forth the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind: and it was so.

At least some other English translations use the same word (I'm not a bible scholar, so I can't give you a detailed list).  But you might try finding out what German bibles use in that passage.

Hi all!

I want to write my Facharbeit (kind of an essay you have to write on a
specific topic you can choose yourself for highschool graduation) about
the type-system of Haskell. It is required in our school to write this
document in German language.

Most time, it is not really difficult to find an appropriate term for
concepts of Haskell, like types (Typen) or type classes (Typklassen).
But I really don't know how to call kinds and sorts in German. Any
ideas?

Yours, Robert Clausecker
