hawaiian coot threats

(9) Comment: The Department of the Navy noted that the 4(d) rule allows take by law enforcement officers for the aiding or euthanizing of sick, injured, or orphaned nene; disposing of a dead specimen; and salvaging a dead specimen that may be used for scientific study. The statewide population was estimated at approximately 600 nene with 390 ± 120 nene on Hawaii and 112 nene on Maui. The existence of captive nene outside of Hawaii provides additional insurance against extinction of the species, but due to concerns about disease introduction, they are not used currently as a source for supplementation of the wild population and are not considered a significant Start Printed Page 69921contributor to conservation of the species. Our Response: We agree that additional outreach regarding the status of nene and associated current issues would further advance the conservation of nene. Our Response: We agree that continued conservation actions are essential to the full recovery of nene. Human-wildlife conflict still exists. Additionally, follow-up surveys of the property by qualified biologists should be arranged by the landowner to assess the status of birds present. We sought comments from independent specialists to ensure that our determination is based on scientifically Start Printed Page 69919sound data, assumptions, and analyses. 0000002204 00000 n 2018, in litt.). The plan focused on maintenance of wild populations through annual releases of captive-reared birds to prevent further population decline, habitat management including control of introduced predators, and conducting research to determine factors preventing nene recovery and appropriate actions to overcome these factors. 10, 12, 17-18, 32-33; Giambelluca 2013, p. 6). The threat of destruction and modification of habitat, particularly in lowland areas, by urbanization and land use conversion, including agriculture, is ongoing and expected to continue to limit the amount of nene foraging and nesting habitat. We updated our Species Information discussion to include the new and most recent statewide population estimates and translocation efforts. 2018, in litt.). First-year mortality was identified as the primary limiting factor for nene in Hawaii Volcanoes National Park. These activities are intended to encourage support for the occurrence of nene in areas with land use practices compatible with the conservation of nene, and to redirect nene away from areas that do not support the conservation of the species. This suggests that although exposure to T. gondii is widespread and ongoing, the threat of disease caused by T. gondii is expected to be low in magnitude and is thus not likely to have population-level impacts on nene into the foreseeable future. All new substantive information has either been incorporated directly into this final rule or is addressed below. We are uncertain as to the impacts on nene into the foreseeable future; however, due to the low incidence, we do not view this a species-level threat. Nene at Hawaii Volcanoes National Park had the lowest annual mortality rates. We did not receive any requests for a public hearing. Proper nutrition is critical for successful reproduction. Collisions at wind energy facilities will result in take of nene now and in the foreseeable future; however, conservation measures in approved and permitted HCPs are expected to offset any population-level impacts to the species. Take by authorized law enforcement officers for the purposes of aiding or euthanizing sick, injured, or orphaned nene; disposing of dead specimens; and salvaging a dead specimen that may be used for scientific study. For example, nene collide with trees, fences, and particularly motor vehicles (Banko and Elder 1990; Banko et al. Amend § 17.11(h) by removing the entry for “Goose, Hawaiian” and adding an entry for “Goose, Hawaiian (Nene)” in its place under BIRDS in the List of Endangered and Threatened Wildlife to read as follows: 3. habitats, threats to their survival and opportunities for volunteer involvement. Migratory Bird Treaty Act (MBTA). Reduced funding beginning in 2009 restricted State funding support of HISC, resulting in a serious setback of conservation efforts (HISC 2009, in litt. This threat is anticipated to be exacerbated by the increasing global surface temperature associated with greenhouse gases resulting from human activities. (16) Comment: Two commenters stated that reclassification of nene will decrease funding for predator control (i.e., mongoose). Techniques for such harassment may include the use of predator effigies (including raptor kites, predator replicas, etc. Reasonable care for habitat management may include, but is not limited to, procuring and implementing technical assistance from a qualified biologist on habitat management activities, and best efforts to minimize nene exposure to hazards (e.g., predation, habituation to feeding, entanglement, and vehicle collisions). on The primary factors affecting the nene recovery in the wild were: (1) Predation by introduced mammalian predators (Factor C); (2) inadequate nutrition (Factor E); (3) lack of lowland habitat (Factor A); (4) human-caused disturbance and mortality (Factor E); (5) behavioral issues (Factor E); (6) genetic issues (Factor E); and (7) disease (Factor C). 2002, p. 1,040). Continuation of current population trends into the future is dependent on, at a minimum, maintaining current levels of management (e.g., predator control and habitat enhancement). Avian botulism has been found on Kauai, Oahu, Molokai, Maui, and Hawaii Island (USGS-NWHC 2017b, in litt.). (33) Comment: Two commenters stated that nene are conservation reliant, especially outside of Kauai. In addition, elevations used by nene vary among sites and among islands, and vegetation available to nene also differs between sites and by island. Hawai'I's coastal plain wetlands are inhabited by five endangered endemic waterbird species. The conservation measures reduce but do not eliminate the threat of vehicle collisions. 1999, p. 40). The black rat and the Norway rat arrived in the islands more recently as stowaways on ships sometime in the late 19th century (Atkinson and Atkinson 2000, p. 25). comm., as cited in USFWS 2004). Today only about 500 acres (202.3 hectares) of taro or other wetland crops remain on the islands. One of these commenters provided an example of an upcoming development on the south shore of Kauai, the “New City” which will encompass 480 acres of planned development. Section 4(d) of the Act states that the “Secretary shall issue such regulations as he deems necessary and advisable to provide for the conservation” of species listed as threatened. Mortality is high in human-modified habitats due to increased predation, collisions, and human-caused accidents (Banko et al. Periods of drought are expected to continue and are likely to be exacerbated by the effects of climate change. Recovery efforts initially focused on the establishment of populations, with the majority of releases of captive-bred nene at high-elevation sanctuaries (above 5,000 ft (1,524 m)) on the islands of Maui and Hawaii. 1999, p. 20). Current populations are sustained by ongoing management (e.g., predator control, habitat management for feral ungulates and nonnative plants). While vehicle collisions could potentially impact certain populations, they do not constitute a threat to the entire species now, and we do not expect them to be a threat in the foreseeable future. Predation by mongoose is a serious threat to nene (see Factor C discussion, above). A species may be determined to be an endangered or threatened species because of any of one or a combination of the five factors described in section 4(a)(1) of the Act: (A) The present or threatened destruction, modification, or curtailment of its habitat or range; (B) overutilization for commercial, recreational, scientific, or educational purposes; (C) disease or predation; (D) the inadequacy of existing regulatory mechanisms; or (E) other natural or manmade factors affecting its continued existence. By allowing take under specified circumstances, the rule will provide needed protection to the species while allowing management flexibility to benefit the species' long-term conservation. Volcanic activity recently impacted nene habitat on the island of Hawaii, but the long-term effects of this activity have yet to be determined. Our Response: We have added unintentional take, specifically harassment, resulting from survey work that benefits and furthers the recovery of nene to the excepted forms of take under Intentional Harassment Not Start Printed Page 69936Likely to Cause Mortality or Direct Injury, below. These opportunities may be used instead of methods identified in the recovery plan. FWS-R1-ES-2017-0050, or upon request from the Pacific Islands Fish and Wildlife Office (see ADDRESSES). Section 4(a)(1) requires that the Secretary determine whether a species is endangered or threatened (or not) because of one or more of five threat factors. Thus, after assessing the best available information, we conclude that the nene is not currently in danger of extinction, but is likely to become in danger of extinction within the foreseeable future throughout all of its range. 432), “for the benefit and enjoyment of the people of the United States” (16 U.S.C. 2:19-31). We have added an analysis of the effects of volcanic activity to portions of nene habitat under Factor A. Vehicle collisions are an ongoing cause of nene injury and mortality; however, we do not have evidence that this factor is limiting population sizes. ABC has over 8,500 members, with offices in For example, although mongoose occur on Hawaii, Maui, and Molokai, Kauai does not yet have an established mongoose population; thus predator control priorities there are different. 1999, pp. 2005, p. 15; Work et al. For the nene, the Service has determined that a 4(d) rule is appropriate as a means to facilitate conservation and expand the species' range by increasing flexibility in management activities for our State partners and private landowners. xii + 116 p. Cowie, ... in high elevation horticultural facilities in Hawaii - a threat to native biodiversity. About the Federal Register Since then, ongoing predator trapping focused in the primary breeding and brooding areas at Hawaii Volcanoes National Park during the breeding season has likely contributed to the overall increase in nene observed. 0000003105 00000 n In addition, a number of zoos and private facilities in the United States and abroad continue to maintain and breed nene in captivity (Kear and Berger 1980, pp. ), totaling 3,252 individuals (DLNR 2018, in litt.). In addition, this rule corrects the Federal List of Endangered and Threatened Wildlife to reflect that Nesochen is not currently a scientifically accepted generic name for this species, and acknowledges the Hawaiian name “nene” as an alternative common name. Avian pox was found in an emaciated bird, but was judged to be a secondary finding (Work et al. Nene populations exist in areas where habitat is used for game enhancement and game populations are maintained at levels for public hunting (HAR-DLNR 2010; see HAR title 13, chapter 123; see Nene Use Area Maps in USFWS 2017). Please see Summary of Factors Affecting the Species, above, for our five-factor analysis on the nene, including new information we received since the publication of the April 2, 2018, proposed rule (83 FR 13919). Our Response: We agree that predatory invasive species such as rats, mongoose, dogs, pigs, and cats are a threat to nene as discussed above under Summary of Factors Affecting the Species. Each document posted on the site includes a link to the Based on the available data, the plan recommended the primary objective to delist the species was establishing a population of 2,000 nene on Hawaii and 250 nene on Maui, well distributed in secure habitat and maintained exclusively by natural reproduction (USFWS 1983, p. 24). 1988). Our Response: As discussed below under comment (12), the Hawaii State Department of Land and Natural Resources (HDLNR) provided us an updated (2017) statewide nene population estimate of 3,252 birds, including 1,482 birds on Kauai, 1,104 birds on Hawaii, and 627 birds on Maui. Fish and Wildlife Service, Exercising the Authority of the Director, U.S. The effect on nene of these changes associated with temperature increase is detailed in the following paragraphs. vi-vii, 1-55, and Appendices A-D). Conservation is defined in the Act to mean “the use of all methods and procedures which are necessary to bring any endangered species or threatened species to the point at which the measures provided pursuant to [the Act] are no longer necessary.” Additionally, section 4(d) of the Act states that the Secretary “may by regulation prohibit with respect to any threatened species any act prohibited under section 9(a)(1). 12/31/2020, by the Food and Nutrition Service This group facilitated the formation of the Hawaii Invasive Species Council (HISC), which was created by gubernatorial executive order in 2002, to coordinate local initiatives for the prevention of introduction, and for control, of invasive species by providing policy-level direction and planning for the State departments responsible for invasive species issues (CGAPS 2009). Three species of introduced rats occur in the Hawaiian Islands. The importation of nondomestic animals (including microorganisms) is regulated by a permit system (HAR 4-71) managed through the Hawaii Department of Agriculture (HDOA), reducing the likelihood of introducing new predators or new diseases that may adversely impact nene. Birds either ingest the toxin directly or may eat invertebrates (e.g., non-biting midges, fly larvae) containing the toxin (USGS-NWHC 2017b, in litt.). He may, for example, permit taking, but not importation of such species,” or he may choose to forbid both taking and importation but allow the transportation of such species, as long as the prohibitions, and exceptions to those prohibitions, will “serve to conserve, protect, or restore the species concerned in accordance with the purposes of the Act” (H.R. or 9(a)(2).” Thus, regulations promulgated under section 4(d) of the Act provide the Secretary with wide latitude of discretion to select appropriate provisions tailored to the specific conservation needs of the threatened species. 14,246-14,248; Giambelluca and Luke 2007, pp. 0000084050 00000 n (3) Comment: The U.S. Department of Agriculture, National Resources Conservation Service (NRCS) commented that the participation of private landowners is considered essential to the recovery of nene, especially on Kauai, where there is limited habitat on Federal land. The capacity of State and Federal agencies and their nongovernmental partners in Hawaii to provide sufficient inspection services, enforce regulations, and mitigate or monitor the effects of nonnative species is limited due to the large number of taxa currently causing damage (CGAPS 2009). However, this reclassification does not significantly change the protection afforded this species under the Act. The following exceptions from prohibitions apply to the nene: (i) Authorization provided under § 17.32. Immunologically naive, juvenile birds are particularly susceptible (Pasick et al. If, during the breeding season, a landowner desires to conduct an action that would intentionally harass nene to address nene loafing or foraging in a given area, a qualified biologist (i.e., an individual with a combination of academic training in the area of wildlife biology or related discipline and demonstrated field experience in the identification and life history of nene) familiar with the nesting behavior of nene must survey in and around the area to determine whether a nest or goslings are present. With regard to threatened wildlife, a permit may be issued for the following purposes: Scientific purposes, to enhance propagation or survival, for economic hardship, for zoological exhibition, for educational purposes, for incidental taking, or for special purposes consistent with the purposes of the Act. (ii) Intentional harassment means an intentional act that creates the likelihood of injury to wildlife by annoying it to such an extent as to significantly disrupt normal behavior patterns, which include, but are not limited to, breeding, feeding, or sheltering. (5) Comment: The NRCS commented that the 4(d) rule is an important mechanism for providing the regulatory assurance needed to successfully implement the voluntary Working Lands for Fish and Wildlife (WLFW) program in Hawaii, as it may provide provisions to ensure that private landowners and citizens are not disproportionately burdened by regulations that do not further the conservation of the species and are excepted from the “take” prohibitions. ; Uyehara 2018, in litt.). xref 59-77; Marshall 2017, pers. 1,165-1,169). As of December 2018, all inspector positions were staffed; however, even with full staffing, only 1 to 5 percent of containers can be inspected (Ige 2018, in litt.). %PDF-1.4 %���� On the main Hawaiian islands, predicted changes associated with increases in temperature include a shift in vegetation zones upslope, a similar shift in animal species' ranges, changes in mean precipitation with unpredictable effects on local environments, increased occurrence of drought cycles, and increases in intensity and numbers of hurricanes (tropical cyclones with winds of 74 miles per hour or higher) (Loope and Giambelluca 1998, pp. Fish and Wildlife Service, Pacific Islands Fish and Wildlife Office, 300 Ala Moana Boulevard, Room 3-122, Honolulu, HI 96850; telephone 808-792-9400. The Present or Threatened Destruction, Modification, or Curtailment of Its Habitat or Range. The President of the United States issues other types of documents, including but not limited to; memoranda, notices, determinations, letters, messages, and orders. The 2004 draft revised recovery plan sets forth the general recovery strategy for nene (USFWS 2004, p. 47), as follows: In order for nene populations to survive they should be provided with generally predator-free breeding areas and sufficient food resources. Nene use of highly altered landscapes and nonnative vegetation can significantly contribute to long-term viability of the population. Over this time frame, we anticipate that threats to nene associated with climate change (e.g., increased duration and intensity of drought, increased frequency and intensity of hurricanes, and flooding associated with hurricanes and sea-level rise) to continue to increase, although we expect the primary issues driving nene population viability will continue to be predation and habitat degradation. Low breeding rates (20 to 63 percent) and low nest success (44 percent) at several sites on Maui and Hawaii from 1979 to 1981 were likely attributable to poor quality or low availability of foods (Banko 1992, pp. This rule formally recognizes that this species is no longer in danger of extinction throughout all or a significant portion of its range and, therefore, does not meet the definition of endangered, but is still impacted by predation, habitat loss and degradation, and inadequacy of regulatory mechanisms to the extent that the species meets the definition of a threatened species under the Act. Information about this document as published in the Federal Register. 2007, p. 1,827). The new information may change the extent to which existing criteria are appropriate for recognizing recovery of the species. 0000109711 00000 n This prototype edition of the These partnerships are voluntary alliances of public and private landowners, “committed to the common value of protecting forested watersheds for water recharge, conservation, and other ecosystem services through collaborative management” (HAWP 2019, entire).
