In my experience, more than in any other subdiscipline of the life sciences, environmental and/or habitat classifications proliferate--and perhaps are difficult to reconcile with one another--for several reasons. However all those reasons seem to be related to the context of the authors, including their primary use cases (e.g. decision support vs. restoration vs. protection vs. environmental impact, ....) and sometimes the organizing community's primary subdiscipline (e.g. ecology vs genomics vs taxonomy vs economic uses vs....). <div>
<br></div><div>So in my opinion, besides granularity, it is perhaps wise to consider the point of view of the authors of a classification to see whether it coincides with your purposes. </div><div><br></div><div>Some more classifications and references:</div>
