In an example used for describing the meaning of the word "biodiversity" in Cambridge dictionary the phrase "species habitat and biodiversity" is used:
the number and types of plants and animals that exist in a particular area or in the world generally, or the problem of protecting this:
a new National Biological Survey to protect species habitat and biodiversity
My question is, shouldn't "species" be used with possessive s? This rises another question: what is the correct form of using the word "species" with possessive s in this context?
