CHAPTER IV: WILDLIFE HABITATS FOR MISSISSIPPI’S SGCN,
THREATS AND CONSERVATION ACTIONS^80

1. THE SUBTYPE CODE


AND NAME


2. THE VALUE TO SPECIES


OF GREATEST


CONSERVATION NEED


Each subtype received a score called a Value to
SGCN. These Values were derived from the
number and Tier level of SGCN associated with
each subtype (see description of Tiers in Criteria
for Selecting and Prioritizing SGCN). They
indicate the relative importance of various habitat
subtypes to SGCN and provide guidance in
predicting were actions will benefit more and/or
higher tier SGCN. Gastropods, insects and
marine fishes were deemed insufficiently known
to warrant status evaluations comparable to
evaluations of vertebrates, mussels, and crayfish
and did not contribute to the subtype value
determinations. Therefore the Values to SGCN
attributed to some subtypes are lower than
expected. Lower than expected Values related to
lack of information are most apparent in some
marine habitat subtypes. Additional work must
be performed to include species from
underrepresented groups in future iterations of
this strategy.

Since Value to SGCN is derived from the

number and Tier level of the species attributed to a
habitat subtype, it does not in all instances indicate
rarity or level of threat to a subtype. It may be
important to consider rarity ranks assigned by the
NHP or other indications of value when assessing
conservation need and implementing actions. Some
SGCN are restricted to subtypes with relatively low
values that may not benefit or could be negatively
affected by conflicting actions performed in subtypes
with higher values. Values are not an indication of
the type of actions recommended. Recommended
conservation actions will vary for each habitat
subtype. For an explanation of how Values were
determined, see Ranking Habitats in Chapter II.


  1. RANK


The Values to SGCN are most useful when
comparing related habitat subtypes. Three major
complexes of related habitat subtypes have been
identified for value comparisons.

Part 2. A Guide to Using this Section


Each of the 17 major wildlife habitat types is coded by number and is described in this chapter. Under each
habitat type is a more detailed description of each subtype, its condition, location, the associated SGCN, the
subtype's rank among similar systems and its value to SGCN. Also included is a general list of prioritized threats
and potential conservation actions. To aid the reader in reviewing and using the habitat types for planning and
management purposes, the following is a guide to material included in the description of each subtype:
