The implicit argument you are making is that something has to be measurable to be worth saving. The most important things in the world you cant measure.

Again, a false dichotomy. The state of many animals is already well known enough, and the problems they face is well known enough. The debate isn't whether to measure or not, but how much measurement occurs and how it reflects the poor state of how conservation works -- which is not the fault of conservationists of course.
