Agree with Bob.
I suspect somewhere that ecosystems and habitats should be given fuzzy definitions, instead of trying to establish a non-overlapping partition.
Or at least, the allocation of species to habitats should be fuzzy. But what a work ...

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....).
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.

Dear all,
I am interested in extending the habitat classification presently used
in
my IRMNG genera and species database from the present "very basic" (marine/nonmarine/both) to something a bit more detailed - maybe
marine,
freshwater, terrestrial with up to perhaps a dozen or so subcategories
of
each, as appropriate (e.g. end up with a little nested hierarchy of
maybe
30-50 terms total).
So, I am looking for suggestions of such classifications as may
already be
in use in order to either pick one up more or less unchanged, or
develop
something with the best features of several. For example I am familiar with the following off the top of my head:
http://sn2000.taxonomy.nl/SyntaxHabitat.htm - 23 terms, coverage a bit uneven
http://mave.tweakdsl.nl/tn/syntax.html - scroll down to the section
headed
"% HABITAT" -- 56 terms, looks quite useable.
Something like the EUNIS classification e.g. as accessible via
http://eunis.eea.europa.eu/habitats-code-browser.jsp possibly gets
too
detailed too quickly at this time for my needs, but you never know
what
may end up being of value.
If list persons can point me at any other resources worth looking at,
or
comment on details of the above, I would be very appreciative. It also occurs to me that some people may have been through this exercise previously, e.g. for "species / structured descriptive data" purposes,
so
any pointers to the results of those deliberations would also be
useful.
Thanks in advance,
