Weed, PLS November 26, 2024 Endangered Species Habitat Suitability Assessment Report To whom it may concern, This letter and enclosed information were prepared in summary of a habitat study performed on a parcel identified as Tax Map Parcel 178.-4 -25 (25 New Street ). The parcel is located on the north side of New Street, approximately 0.12 ± miles west of Route 50 , and approximately 400± feet east of Empire Avenue, in the City of Saratoga Springs. Currently the subject parcel contains a one story metal garage , associated asphalt driveway, parking lot, overgrown lawn area with a few scattered trees within the lawn area , with the remaining land being wooded. An inquiry was submitted to U.S. Fish and Wildlife Service through the IP a C website to identify any potential threatened/endangered species that may occur within the subject parcel. The Service identified the following species are potentially affected by activities in this location; the Northern Long-eared Bat (Myotis septentrionalis), (endangered) and the Tricolored Bat (Perimyotis subflavus), and the Karner Blue Butterfly (Lycaeides melissa samuelis), (endangered ). A habitat suitability assessment was completed for the Northern Long- eared Bat (Myotis septentrionalis), the Tricolored Bat (Perimyotis subflavus), the Karner Blue Butterfly (Lycaeides melissa samuelis) and the Frosted Elfin Butterfly (Callophrys irus). Species Requirements - Northern Long -eared Bat: According to the U.S. Fish and Wildlife Service’s website, “During summer, northern long -eared bats roost singly or in colonies underneath bark, in cavities, or in crevices of both living and dead trees. Males and non - reproductive females may also roost in cooler places, like caves and mines. This bat seems opportunistic in selecting roosts, using tree species based on suitability to retain bark or provide cavities or crevices. It has also been found, rarely, roosting in structures like barns and sheds. Northern long-eared bats spend winter hibernating in caves and mines, called hibernacula. They typically use large caves or mines with large passages and entrances; constant temperatures; and high humidity with no air currents. Specific areas where they hiber nate have very high humidity, so much so that droplets of water are often seen on their fur. Within hibernacula, surveyors find them in small crevices or cracks, often with only the nose and ears visible. Northern long-eared bats emerge at dusk to fly thro ugh the understory of forested hillsides and ridges feeding on moths, flies, leafhoppers, caddisflies, and beetles, which they catch while in flight using echolocation. This bat also feeds by gleaning motionless insects from vegetation and water surfaces.” Species Requirements – Tricolored Bat: According to the U.S. Fish and Wildlife Service’s website, Tricolored bat habitat consists of “During the spring, summer, and fall - collectively referred to as the non -hibernating seasons - tricolored bats primarily roost among live and dead leaf clusters of live or recently dead deciduous hardwood trees. In the southern and northern portions of the range, tricolored bats will also roost in Spanish moss (Tillandsia usneoides) and Usnea trichodea lichen, respectively. In addition, tricolored bats have been observed roosting during summer among pine needles, eastern red cedar (Juniperus virginiana ), within artificial roosts like barns, beneath porch roofs, bridges, concrete bunkers, and rarely within caves. Fem ale tricolored bats exhibit high site fidelity, returning year after year to the same summer roosting locations. Female tricolored bats form maternity colonies and switch roost trees regularly. Males roost singly. During the winter, tricolored bats hiberna te - which means that they reduce their metabolic rates, body temperatures and heart rate - in caves and mines; although, in the southern United States, 4 | P a g e where caves are sparse, tricolored bats often hibernate in road -associated culverts, as well as sometimes in tree cavities and abandoned water wells. Tricolored bats exhibit high site fidelity with many individuals returning year after year to the same hib ernaculum. Tricolored bats are opportunistic feeders and consume small insects including caddisflies, moths, beetles, wasps, flying ants and flies. Tricolored bats emerge early in the evening and forage at treetop level or above, but may forage closer to ground later in the evening. This species of bat exhibits slow, erratic, fluttery flight, while foraging and are known to forage most commonly over waterways and forest edges.” Species Requirements – Karner Blue Butterfly : According to the U.S. Fish and Wildlife Service’s website, “Karner blues are found in the northern range of wild lupine habitat. Wild Lupine (Lupinus perennis) is an attractively flowered plant that occurs in pine barrens and oak savannas in Indiana, Michigan, Minnesota, New Hampshire, New York, and Wisconsin. The Karner Blue’s habitat is a patchwork of pine and scrub oak scattered among open grassy areas. Hist orically, a network of these openings among the trees was maintained by wildfire and at one time, the butterfly was found in this habitat in a nearly continuous narrow band across 10 states and one province. Today it h as been eliminated from at least five of these states. Karner blue caterpillars feed only on the leaves of the wild lupine plant. Adults feed on the nectar of flowering plants. This severely restricts where they can survive.” Species Requirements - Frosted Elfin Butterfly: According to the U.S. Fish and Wildlife Service’s website, “The entire lifecycle of a frosted elfin is completed within one year. Adults emerge in spring and lay eggs; eggs hatch into larvae that rely on specific host plants of wild lupine or wild indigo, larvae pupate by late July , on or near host plants and remain in this state until the following spring. Frosted elfin depend on pine barrens, this rare type of habitat is characterized by sandy soil, an overstory of fire-dependent conifers, and grassy open ings that support plants like blue lupine and wild indigo. Frosted elfin lay their eggs on these two plants alone; their larvae need to feed on them to survive.” Habitat Suitability – Northern Long -eared Bat & Tricolored Bat: The subject parcel is approximately 6.50± acres in size. Approximately 2.20 ± acres are currently developed consisting of a one story metal garage, asphalt driveway and parking lots. Approximately 2.00± acres consist of overgrown lawn area with the remaining 2.30± acres being forested. The proposed project includes the removal of all existing site features, with the new construction of 18 new buildings, associated driveways, with the installation and connection to public utility services. For the proposed project there will be approximately 2.30± acres of tree clearing required. The dominant tree species identified onsite consisted of Red Maple, Red Oak, Poplar and White Pine, which are relatively smooth bark trees which are not suitable ha bitat for the Bats. There are a few standing dead trees scattered throughout the forested area onsite that do possess exfoliating bark or crevices which are characteristics of suitable habitat. If tree clearing is conducted within winter months while Bats are located in hibernaculum we feel this project will have no effect on Northern Long- eared Bat and/or Tricolored Bat roosting habitat. There are no wetlands onsite that will provide an abundance of flying insects, and therefore potential foraging habitat for the Bats. Therefore, we feel this project will have no effect on Northern Long-eared Bats and/or Tricolored Bat foraging habitat. There are no known maternal roost trees onsite, and the project site is not located within 0.25 miles of a hibernaculum. Habitat Suitability – Karner Blue Butterfly & Frosted Elfin Butterfly : Currently the area of review consists of an existing one story metal garage, associated asphalt d riveway, parking area, overgrown lawn area with scattered trees within the lawn area with the remaining land being forested areas. The lawn area lacks an overhead canopy and consists of sandy soils which are suitable for Wild Lupine and Wild Indigo to grow. Therefore, multiple site inspections have taken place during June and July when Wild Lupine and Wild Indigo would be present, none were identified. Because there was no Wild Lupine/Wild Indigo present onsite the potential for Karner Blue Butterfly and/or Frosted Elfin Butterfly to be present onsite is very minimal due to the lack of Wild Lupine/Wild Indigo being present onsite. The forested areas on the site show no signs of natural disturbance and have a greater than 50 percent canopy that would prohibit the growth of Wild Lupine and/or Wild Indigo . Because of the overhead canopy creating a shaded environment in the forested areas of the site, and a lack of natural disturbance, the forested areas onsite are not suitable for Wild Lupine/Wild Indigo to grow. Furthermore, while onsite performing the habitat assessment no Karner Blue Butterflies or Frosted Elfin Butterflies were seen . 5 | P a g e This habitat assessment was performed according to the Karner Blue Butterfly (Lycaeides Melissa samuelis) Survey Protocols Within the State of New York, Prepared by: U.S. Fish and Wildlife Service (Service), New York Field Office New York State Department of Environmental Conservation (NYSDEC), dated May 2008. This habitat assessment was also performed according to the Frosted Elfin Habitat and Butterfly Survey Protocol, prepared by U.S. Fish and Wildlife Service, dated December 2019. https://www.fws.gov/northeast/nyfo/es/KBBPASurveyProtocols12May2008.pdf https://www.fws.gov/northeast/frosted -elfin/pdf/2020 -Frosted -Elfin -Survey -Protocol.pdf Both survey protocol requirements state that there are four phases of the butterfly surveys, in which the first step is a preliminary site assessment needed to identify potential butterfly habitat. If during the preliminary site assessment any of the following f actors occur onsite, it will disqualify a part or all of the site from needing further assessment. ● Agriculture: exclude only active row -cropped agricultural lands and fallow fields [Note that other open agricultural areas may support host plants and may be included]; ● Active management: exclude areas with ongoing land management, forestry, or construction operations that will temporarily impede surveys, access, or habitat phenology; ● Mowed/lawn/hay: exclude areas regularly mowed during the growing season including lawns and some hay fields [Note that warm season grasses, such as little bluestem grass, are typically not harvested until after host plants have senesced and flight period is complete and may be included]; ● Paved/developed: exclude paved and non -vegetated developed areas such as parking lots, buildings, and roads; ● Closed canopy: exclude areas with >50% canopy cover (only if there are no openings, trails, or paths through such areas); such areas will have shade for most or all of the day; ● Wet soil: exclude areas with non -sandy or poorly drained soils; ● Thick vegetation: exclude areas with complete shrub or herbaceous cover other than the host plant; ● Imminent conversion: exclude areas where conversion/development of the habitat is immediately imminent. Therefore, because the site consists entirely of three of the listed factors (Mowed/lawn/hay, Closed canopy and Paved/developed) further assessment of the site is not necessary.

The list may also include trust resources that occur outside of the project area, but that could potentially be directly or indirectly aected by activities in the project area. However, determining the likelihood and extent of eects a project may have on trust resources typically requires gathering additional site-specic (e.g., vegetation/species surveys) and project-specic (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 oce(s) with jurisdiction in the dened 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.

The primary information used to generate this list is the known or expected range of each species. Additional areas of inuence (AOI) for species are also considered. An AOI includes areas outside of the species range if the species could be indirectly aected by activities in that area (e.g., placing a dam upstream of a sh population even if that sh does not occur at the dam site, may indirectly impact the species by reducing or eliminating water ow 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 eects to species, additional site-specic and project-specic 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 oce and a species list which fullls this requirement can only be obtained by requesting an ocial species list from either the Regulatory Review section in IPaC (see directions below) or from the local eld oce directly. For project evaluations that require USFWS concurrence/review, please return to the IPaC website and request an ocial species list by doing the following: 1.

For additional information on bald eagles, refer to Bald Eagle Nesting and Sensitivity to Human Activity For guidance on when to schedule activities or implement avoidance and minimization measures to reduce impacts to migratory birds on your list, see the PROBABILITY OF PRESENCE SUMMARY below to see when these birds are most likely to be present and breeding in your project area. BREEDING SEASON Probability of Presence Summary The graphs below provide our best understanding of when birds of concern are most likely to be present in your project area. This information can be used to tailor and schedule your project activities to avoid or minimize impacts to birds. Please make sure you read "Supplemental Information on Migratory Birds and Eagles", specically 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 eort (see below) can be used to establish a level of condence in the presence score. One can have higher condence in the presence score if the corresponding survey eort 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 Supplemental Information for Migratory Birds and Eagles in IPaC https://www.fws.gov/media/supplemental-information- migratory-birds-and-bald-and-golden-eagles-may-occur-project-action NAME Bald Eagle Haliaeetus leucocephalus This is not a Bird of Conservation Concern (BCC) in this area, but warrants attention because of the Eagle Act or for potential susceptibilities in oshore areas from certain types of development or activities. Breeds Dec 1 to Aug 31  no data survey eort breeding season probability of presence 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 Eort () 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 eort 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. Survey Timeframe Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The exception to this is areas o the Atlantic coast, where bird returns are based on all years of available data, since data in these areas is currently much more sparse.

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 proles 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 specied. 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 Pacic 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 oshore areas from certain types of development or activities (e.g. oshore energy development or longline shing). Although it is important to try to avoid and minimize impacts to all birds, eorts 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 aected by oshore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area o the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also oers 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 les 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 Diving Bird Study and the nanotag 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 specied 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. On the graphs provided, please also look carefully at the survey eort (indicated by the black vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high survey eort is the key component. If the survey eort is high, then the probability of presence score can be viewed as more dependable. In contrast, a low survey eort 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 conrm 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 conrmed. 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. Facilities National Wildlife Refuge lands Any activity proposed on lands managed by the National Wildlife Refuge system must undergo a 'Compatibility Determination' conducted by the Refuge. Please contact the individual Refuges to discuss any questions or concerns. There are no refuge lands at this location. Fish hatcheries There are no sh hatcheries at this location. Wetlands in the National Wetlands Inventory (NWI) Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under 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 Corps of Engineers District. This location did not intersect any wetlands mapped by NWI. 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 identied 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 classication 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 verication 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 eld work. There may be occasional dierences in polygon boundaries or classications 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 tubercid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. Data precautions Federal, state, and local regulatory agencies with jurisdiction over wetlands may dene and describe wetlands in a dierent manner than that used in this inventory. There is no attempt, in either the design or products of this inventory, to dene 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 modications within or adjacent to wetland areas should seek the advice of appropriate Federal, state, or local agencies concerning specied agency regulatory programs and proprietary jurisdictions that may aect such activities.
