Chapter 3 ⎯ Affected EnvironmentReptiles. There are no native terrestrial reptiles on the Hawaiian Islands. Nonnative reptiles that havethe potential to inhabit the SBMR, WAAF, and SRAA ROI include the green anole (Anolis carolinenesis),mourning gecko (Lepidodactylus lugubris), stump-toed gecko (Gehyra mutilata), tree gecko(Hemiphyllodactylus typus), Indo-Pacific gecko (Hemidactylus garnotii), house gecko (H. frenatus),metallic skink Lampropholis delicata), and gold dust day gecko (Phelsuma laticauda laticauda). Theonly known terrestrial snake occurring on the Hawaiian Islands is the island blind snake (Ramphotyphlopsbraminus), although the brown tree snake (Boiga irregularis) has been found in Hawaii at airportsand other ports of entry; attempts are being made to prevent this species from establishing itselfon the Hawaiian Islands. The red-eared turtle (Trachemys scripta elegans) was recorded at WaikeleStream and may be found at SBMR. This species was also identified in Kaukonahua Stream (KiikiiStream), the primary drainage of Poahmoho tributary on KTA, and may be found at SBER(USARHAW and 25th ID [L] 2001a).Terrestrial Mammals. The Hawaiian hoary bat (Lasiurus cinereus semotus) is the only native terrestrialmammal on the Hawaiian Islands (USFWS 1998a), but is not considered present on Oahu. Thefollowing nonnative mammals may occur at SBMR and SRAA: feral pigs (Sus scrofa scrofa), feralgoats (Capra hircus hircus), feral cats (Felis catus), feral dogs (Canis familiaris familiaris), Norwayrats (Rattus norvegicus), black rats (R. rattus), Polynesian rats (R. exulans hawaiiensis), and housemice (Mus musculus).Birds. The following indigenous species have been recorded at the SBMP: Oahu elepaio (Chasiempissandwichensis ibidis), Oahu creeper (Paroreomyza maculatus), iiwi (Vestiaria coccinea), apapane(Hiatione sanguinea sanguinea), Oahu amakihi (Hemignathus virens chloris), white-tailed tropic bird(Phaethon lepturus dorotheae), black-crowned night heron (Nycticorax nycticorax hoactli), Pacificgolden-plover (Pluvialis fulva), and the Hawaiian short-eared owl (Asio flammeus sandwichensis),also known as pueo. The Oahu elepaio, Oahu creeper, iiwi, Oahu amakihi, and apapane are all specieslimited to the Hawaiian Islands. Native birds recorded at SBER include the Oahu elepaio, Oahucreeper, iiwi, Oahu amakihi, apapane, and Oahu akepa (Loxops coccineus wolstenholmii), the whitetailedtropic bird, black-crowned night heron, and the Pacific golden-plover. Hawaiian short-earedowls are known to inhabit areas adjacent to the SRAA and may occur on the property (TNC 2000).Mostly nonnative and common birds, such as the myna (Acridotheres tristis), are expected to use theSRAA because of its highly disturbed nature and the agricultural habitat that it provides. Numerousnonnative bird species are known to occur in SBMR and the SRAA (USAG-HI 2004).Fish. The following endemic fish are known to inhabit the Waikele Stream, which runs throughSBMP: oopu nakea (Awaous guamensis), oopu naniha (Stenogobius hawaiiensis), oopu hiukole, oopuokuhe (Eleotris sandwichensis), aholehole (Kuhlia sandvicensis), and amaama (Mugil cephalus)(USARHAW and 25th ID [L] 2001a). Although these species have not been confirmed on SBMP,they may occur within that portion of the waterway. No fish data are available specific to KaukonahuaSouth Fork Stream on SBER (USARHAW and 25th ID [L] 2001a), but information was gatheredfor Kaukonahua (Kiikii) Stream, which includes the Poamoho tributary on KTA and may representsome species at SBER. Native fish identified from the Kaukonahua Stream assessment include oopunakea, oopu naniha, oopu okuhe, and oopu hiukole (USARHAW and 25th ID [L] 2001a). Severalnonnative species are known to occur in SBMR, and several additional nonnative species may be present(USAG-HI 2004). The Lake Wilson overflow channel, which Helemano Trail would cross, isperennial but it is not known if fish inhabit this human-made stream. There is no documented aquaticspecies information available for the SRAA.Threatened and Endangered Species/Sensitive HabitatsSensitive Plant Species. The training areas that make up SBMR are home to 59 rare plant species. TheUSFWS has also designated critical habitat for areas within the SBMR ROI, but there is no desig-February 2008 3–63 2/25th SBCT Final EIS
