Summary of Potential Effects of Implementing Alternatives A, B, or C
for the Seal Beach National Wildlife Refuge Comprehensive Conservation Plan
Resource Alternative A Alternative B Alternative C
Biological Resources
Waterfowl, Seabirds,
Shorebirds and Other
Waterbirds
Landbirds
Fish and other Marine
Organisms
Invertebrates, Amphibians,
and Reptiles
Not likely to result in
any changes to the
current diversity and
abundance
Not likely to result in
any changes to the
current diversity and
abundance of these
birds on the Refuge
Ongoing Refuge
maintenance projects,
such as culvert
replacement, indirectly
benefits fish by
improving water
circulation in the
marsh
Presence/ distribution
of invertebrates,
amphibians, and
reptiles would be
unlikely to change
Habitat restoration and
enhancement activities
would provide minor
benefits to these birds
Would likely result in a
minor, indirect adverse
effect to landbirds due to
conversion of existing
disturbed upland habitat
to salt marsh and
wetland/upland
transitional habitat
Proposed restoration and
enhancement projects
would likely result in
some indirect beneficial
effects to fish
populations;
implementing BMPs and
other conditions during
the application of
pesticides would
minimize the potential for
adverse effects; the use
of Natular in coastal
wetlands could adversely
affect fish and marine
organisms
Minor, indirect adverse
effects could result from
restoration/enhancement
projects due to loss of
transitional habitat;
BMPs during pesticide
use will minimize adverse
effects from pesticides
Same as Alternative B
Less likely to result in a
minor, indirect adverse
effect to landbirds as
existing disturbed
upland habitat would
be converted primarily
to native upland and
wetland/upland
transitional habitat
Same as Alternative B,
except Natular is not
proposed for use on the
Refuge under this
alternative
Generally the same as
Alternative B, but under
Alternative C a tiger
beetle management
plan would be
implemented to protect
tiger beetle populations
on the Refuge
