IPaC resource list
U.S. Fish & Wildlife Service
This report is an automatically generated list of species and other resources such as
critical habitat (collectively referred to as trust resources) under the U.S. Fish and Wildlife
Service's (USFWS) jurisdiction that are known or expected to be on or near the project
area referenced below. The list may also include trust resources that occur outside of the
project area, but that could potentially be directly or indirectly affected by activities in the
project area. However, determining the likelihood and extent of effects a project may have
on trust resources typically requires gathering additional site -specific (e.g.,
vegetation/species surveys) and project -specific (e.g., magnitude and timing of proposed
activities) information.
Below is a summary of the project information you provided and contact information for
the USFWS office(s) with jurisdiction in the defined project area. Please read the
introduction to each section that follows (Endangered Species, Migratory Birds, USFWS
Facilities, and NWI Wetlands) for additional information applicable to the trust resources
addressed in that section.

Endangered species
The primary information used to generate this list is the known or expected range of each
species. Additional areas of influence (AOI) for species are also considered. An AOI
includes areas outside of the species range if the species could be indirectly affected by
activities in that area (e.g., placing a dam upstream of a fish population even if that fish
does not occur at the dam site, may indirectly impact the species by reducing or
eliminating water flow downstream). Because species can move, and site conditions can
change, the species on this list are not guaranteed to be found on or near the project
area. To fully determine any potential effects to species, additional site -specific and
project -specific information is often required.
Section 7 of the Endangered Species Act requires Federal agencies to "request of the
Secretary information whether any species which is listed or proposed to be listed may be
present in the area of such proposed action" for any project that is conducted, permitted,
funded, or licensed by any Federal agency. A letter from the local office and a species list
which fulfills this requirement can only be obtained by requesting an official species list
from either the Regulatory Review section in IPaC (see directions below) or from the local
field office directly.
For project evaluations that require USFWS concurrence/review, please return to the IPaC
website and request an official species list by doing the following:
1. Draw the project location and click CONTINUE.
2. Click DEFINE PROJECT.
3. Log in (if directed to do so).
4. Provide a name and description for your project.
5. Click REQUEST SPECIES LIST.

you read "Supplemental Information on Migratory Birds and Eagles", specifically the FAQ
section titled "Proper Interpretation and Use of Your Migratory Bird Report" before using
or attempting to interpret this report.
Probability of Presence( )
Each green bar represents the bird's relative probability of presence in the 10km grid
cell(s) your project overlaps during a particular week of the year. (A year is represented as
12 4-week months.) A taller bar indicates a higher probability of species presence. The
survey effort (see below) can be used to establish a level of confidence in the presence
score. One can have higher confidence in the presence score if the corresponding survey
effort is also high.
How is the probability of presence score calculated? The calculation is done in three steps:
1. The probability of presence for each week is calculated as the number of survey events
in the week where the species was detected divided by the total number of survey
events for that week. For example, if in week 12 there were 20 survey events and the
Spotted Towhee was found in 5 of them, the probability of presence of the Spotted
Towhee in week 12 is 0.25.
2. To properly present the pattern of presence across the year, the relative probability of
presence is calculated. This is the probability of presence divided by the maximum
probability of presence across all weeks. For example, imagine the probability of
presence in week 20 for the Spotted Towhee is 0.05, and that the probability of
presence at week 12 (0.25) is the maximum of any week of the year. The relative
probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2.
3. The relative probability of presence calculated in the previous step undergoes a
statistical conversion so that all possible values fall between 0 and 10, inclusive. This is
the probability of presence score.
To see a bar's probability of presence score, simply hover your mouse cursor over the bar.
Breeding Season (
Yellow bars denote a very liberal estimate of the time -frame inside which the bird breeds
across its entire range. If there are no yellow bars shown for a bird, it does not breed in
your project area.
Survey Effort ( )
Vertical black lines superimposed on probability of presence bars indicate the number of
surveys performed for that species in the 10km grid cell(s) your project area overlaps. The
number of surveys is expressed as a range, for example, 33 to 64 surveys.
To see a bar's survey effort range, simply hover your mouse cursor over the bar.
No Data( )
A week is marked as having no data if there were no survey events for that week.

What does IPaC use to generate the potential presence of bald and golden eagles in my specified
location?
The potential for eagle presence is derived from data provided by the Avian Knowledge-Network-(AKN).
The AKN data is based on a growing collection of survey_,banding, and citizen science datasets and is
queried and filtered to return a list of those birds reported as occurring in the 1 Okm grid cell(s) which
your project intersects, and that have been identified as warranting special attention because they are a
BCC species in that area, an eagle (Eagle Act requirements may apply). To see a list of all birds
potentially present in your project area, please visit the Rapid Avian Information Locator (RAIL} Tool.

Tell me more about conservation measures I can implement to avoid or minimize impacts to
migratory birds.
Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all
birds at any location year round. Implementation of these measures is particularly important when
birds are most likely to occur in the project area. When birds may be breeding in the area, identifying
the locations of any active nests and avoiding their destruction is a very helpful impact minimization
measure. To see when birds are most likely to occur and be breeding in your project area, view the
Probability of Presence Summary. Additional measures or permits may be advisable depending on the
type of activity you are conducting and the type of infrastructure or bird species present on your project
site.

location?
The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other
species that may warrant special attention in your project location.
The migratory bird list generated for your project is derived from data provided by the Avian Knowledge
Network (AKN). The AKN data is based on a growing collection of survey_, banding, and citizen science
datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid
cell(s) which your project intersects, and that have been identified as warranting special attention
because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species
that has a particular vulnerability to offshore activities or development.
Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project
area. It is not representative of all birds that may occur in your project area. To get a list of all birds
potentially present in your project area, please visit the Raapid Aviarclnformation Locator (RAI ) Tool.
What does IPaC use to generate the probability of presence graphs for the migratory birds
potentially occurring in my specified location?
The probability of presence graphs associated with your migratory bird list are based on data provided
by the Avian Knowledge Network (AiS_N). This data is derived from a growing collection of survey,.
Probability of presence data is continuously being updated as new and better information becomes
available. To learn more about how the probability of presence graphs are produced and how to
interpret them, go the Probability of Presence Summary and then click on the "Tell me about these
graphs" link.
How do I know if a bird is breeding, wintering or migrating in my area?
To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering,
migrating or year-round), you may query your location using the RAIL Tool and look at the range maps
provided for birds in your area at the bottom of the profiles provided for each bird in your results. If a
bird on your migratory bird species list has a breeding season associated with it, if that bird does occur
in your project area, there may be nests present at some point within the timeframe specified. If
"Breeds elsewhere" is indicated, then the bird likely does not breed in your project area.
What are the levels of concern for migratory birds?
Migratory birds delivered through IPaC fall into the following distinct categories of concern:
1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout
their range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the
Virgin Islands);
2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs)
in the continental USA; and
3. "Non -BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either
because of the Eagle Act requirements (for eagles) or (for non -eagles) potential susceptibilities in
offshore areas from certain types of development or activities (e.g. offshore energy development or
longline fishing).

Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in
particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of
rangewide concern. For more information on conservation measures you can implement to help avoid
and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics.
Details about birds that are potentially affected by offshore projects
For additional details about the relative occurrence and abundance of both individual bird species and
groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean
Data Portal. The Portal also offers data and information about other taxa besides birds that may be
helpful to you in your project review. Alternately, you may download the bird model results files
underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive
Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project
webpage.
Bird tracking data can also provide additional details about occurrence and habitat use throughout the
year, including migration. Models relying on survey data may not include this information. For
additional information on marine bird tracking data, see the ❑ivingl3ird Swiy and the nanot g studies
or contact Caleb Spiegel or Pam Loring.
What if I have eagles on my list?
If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid
violating the Eagle Act should such impacts occur.
Proper Interpretation and Use of Your Migratory Bird Report
The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of
priority concern. To learn more about how your list is generated, and see options for identifying what
other birds may be in your project area, please see the FAQ "What does IPaC use to generate the
migratory birds potentially occurring in my specified location". Please be aware this report provides the
"probability of presence" of birds within the 10 km grid cell(s) that overlap your project; not your exact
project footprint. ❑n the graphs provided, please also look carefully at the survey effort (indicated by
the black vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high
survey effort is the key component. If the survey effort is high, then the probability of presence score
can be viewed as more dependable. In contrast, a low survey effort bar or no data bar means a lack of
data and, therefore, a lack of certainty about presence of the species. This list is not perfect; it is simply
a starting point for identifying what birds of concern have the potential to be in your project area, when
they might be there, and if they might be breeding (which means nests might be present). The list helps
you know what to look for to confirm presence, and helps guide you in knowing when to implement
conservation measures to avoid or minimize potential impacts from your project activities, should
presence be confirmed. To learn more about conservation measures, visit the FAQ "Tell me about
conservation measures I can implement to avoid or minimize impacts to migratory birds" at the bottom
of your migratory bird trust resources page.

Section 404 of the Clean Water Act, or other State/Federal statutes.
For more information please contact the Regulatory Program of the local U.S. Army(2Lp5
of Engineers District.
Please note that the NWI data being shown may be out of date. We are currently working
to update our NWI data set. We recommend you verify these results with a site visit to
determine the actual extent of wetlands on site.
This location overlaps the following wetlands:
.AU/10041111
R4SBC

NOTE: This initial screening does not replace an on -site delineation to determine whether
wetlands occur. Additional information on the NWI data is provided below.
Data limitations
The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level
information on the location, type and size of these resources. The maps are prepared from the analysis
of high altitude imagery. Wetlands are identified based on vegetation, visible hydrology and geography.
A margin of error is inherent in the use of imagery; thus, detailed on -the -ground inspection of any
particular site may result in revision of the wetland boundaries or classification established through
image analysis.
The accuracy of image interpretation depends on the quality of the imagery, the experience of the
image analysts, the amount and quality of the collateral data and the amount of ground truth
verification work conducted. Metadata should be consulted to determine the date of the source
imagery used and any mapping problems.
Wetlands or other mapped features may have changed since the date of the imagery or field work.
There may be occasional differences in polygon boundaries or classifications between the information
depicted on the map and the actual conditions on site.
Data exclusions
Certain wetland habitats are excluded from the National mapping program because of the limitations of
aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or
submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and
nearshore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also
been excluded from the inventory. These habitats, because of their depth, g❑ undetected by aerial
imagery.
Data precautions
Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe
wetlands in a different manner than that used in this inventory. There is no attempt, in either the
design or products of this inventory, to define the limits of proprietary jurisdiction of any Federal, state,
or local government or to establish the geographical scope of the regulatory programs of government
agencies. Persons intending to engage in activities involving modifications within or adjacent to wetland
areas should seek the advice of appropriate Federal, state, or local agencies concerning specified
agency regulatory programs and proprietary jurisdictions that may affect such activities.
