Around the globe, fish and wildlife managers are facing increasingly complex management issues because of multiscale ecological effects like climate change, species invasion, and land-use change. Managers seeking to prevent extinctions or preserve ecosystems are increasingly considering more interventionist techniques to overcome the resulting changes. Among those techniques, translocation methods that intentionally move species into new, less impacted habitats are being considered. These types of translocations are known by a range of terms, including “managed relocation” and “assisted migration,” but the International Union for the Conservation of Nature’s Species Survival Commission (IUCN SSC, 2013) has proposed...
This two-page document is a summary of the USFWS decision support framework effort as of August 2023. The U.S. Fish and Wildlife Service’s (USFWS) decision support framework for conservation introductions (framework) aims to foster inclusive, transparent and defensible decision making about when to use conservation introductions as a strategy for preventing species extirpation or extinction, re-establishing an ecological function lost through extinction, or directing ecosystem change toward a state that better supports conservation goals. The framework is being developed for use by the USFWS in Hawaiʻi, Idaho, Oregon, Washington, American Samoa, Commonwealth of the Northern Mariana Islands, Guam, Federated States...
ABSTRACT: This project will place the PNW Coast LCD on a pathway for successfully engaging private landowners and increase the likelihood that the products of the LCD effort will be used to drive conservation in the region for years to come.The first goal is to develop a logical, sequential, effective strategy to engage private lands in the various facets and phases of the LCD effort. Having a jointly-developed landowner engagement strategy recognizes that this landscape design process should be conducted in close partnership with those whom we rely on to continue producing environmental values. The second goal is to implement initial steps of the landowner engagement strategy. These early implementation steps...
The goal of the Hawaiian Islands Climate Synthesis Project was to develop comprehensive, science-based syntheses of current and projected future climate change impacts on, and adaptation options for, terrestrial and freshwater resources within the main Hawaiian Islands. The Hawaiian Islands Climate Vulnerability and Adaptation Synthesis presents the results of the major project components - climate impacts assessment, vulnerability assessment, and adaptation planning - and provides an inter-island analysis of the findings. More detailed information is available in the individual vulnerability assessment syntheses and adaptation summaries, and should be referred to for decision support.
The Hawai‘i Biannual Waterbird Survey (Survey) has evolved since its establishment in 1955 to meet changing information needs for the conservation of endemic and migratory waterbirds in Hawai‘i. From 2005 to 2015, information needs for the management and recovery of endemic, endangered waterbirds were not being addressed by the Survey. Although waterbird counts continued during this time, data entry and management lapsed and reconciliation of spatial and tabular data was only partially completed by 2007. As a result, analyses of count data, distribution, and population trends were out of date and of limited utility for informing recovery objectives and waterbird conservation efforts. U.S. Fish and Wildlife Service...

This final report summarizes: • Monthly Productivity and Carrying Capacity surveys and community engagement. • 'Opihi habitat model reflective of 1) seasonal shifts in intertidal resources from monthly surveys, and 2) shifts in intertidal habitat under 0.5 - 2.0 m sea level rise. • Maps of current and future 'Opihi habitat.
The USFWS (Service) supports the State of Hawai‘i in conserving endangered Hawaiian forest birds, through technical assistance and management support. Two critically endangered forest birds endemic to Kauaʻi, the ‘Akikiki and the ‘Akeke‘e, are facing imminent extinction (potentially within three years) if immediate action is not taken. The most important threat is introduced mosquito-borne diseases, amplified by climate change due to the movement of disease-carrying mosquitoes into high-elevation refugia as warming progresses. This threat cannot yet be addressed at a landscape level on Kaua‘i. A Service-funded structured decision-making process identified translocation as the next appropriate option for their conservation....
PDF Portfolio for Kaua'i island, providing a compilation of the available products from the Hawaiian Islands Climate Synthesis.
We used Maximum Entropy (MaxEnt) modelling (Phillips et al. 2006) to assess the potential habitat suitability on Maui Island for translocation of endemic Kauai bird species Oreomystis bairdi (Akikiki, AKIK) and Loxops caeruleirostris (Akekee, AKEK), as well asthreatened endemic Maui bird species Palmeria dolei (Akohekohe, AKOH), Paroreomyza montana (Maui Alauahio, MAAL), and Pseudonestor xanthophrys (Kiwikiu, MAPA). All of these species are classified as endangered by the US Fish & Wildlife Service except MAAL (which is considered endangered by IUCN). This work is a follow-up of (Fortini et al. 2017) , which considered the suitability of habitat for inter-island translocation of AKEK and AKIK based on climate ranges...
ABSTRACT: Guano has shown promise as a means of detecting Pd exposure in bats and is being investigated for its potential use for early detection in areas where sampling bats during winter is not feasible. Pilot work at a small number of summer roosts in Wisconsin and Washington in Summer 2017 demonstrated that Pd could be detected from guano accumulating under above-ground bat roosts for up to a 28-day period throughout the summer. We are requesting funds to extend this project into spring 2019 in order to increase the number of above-ground summer roosts within approximately 250 km of known Pd range of species known or suspected to susceptible to WNS necessary to evaluate this sampling method as a reliable...
The development of a Climate Change Monitoring Network (CCMN) for Hawai’i is a shared goal of a wide variety of Federal, State, and local agencies and other entities charged with understanding and managing natural resources in the State. This CCMN would integrate repeated measurements of geophysical variables (e.g., solar radiation, rainfall, relative humidity, soil moisture, stream flow) and biological variables (e.g., vegetation composition, bird abundance, stream organisms) to provide an enhanced ability to understand ongoing and future changes in Hawai’i. To support this effort, this project developed a series of tools, GIS maps, and plots to visualize the unique and complex climate on the islands of Hawai’i....
The endemic subspecies of the Pacific sheath-tailed bat (payeyi; Emballonura semicaudata rotensis), and the Mariana swiftlet (chachaguak; Aerodramus bartschi) once inhabited many of the islands that comprise the Mariana archipelago (Lemke 1986, Flannery 1995, Ellison et al. 2003, Cruz et al. 2008). Both are insectivorous species that roost or nest almost exclusively in natural limestone caves (Pratt et al. 1987). Population threats to these two species primarily include habitat loss from past clearing of native forest for agriculture, with subsequent replacement by invasive vegetation (particularly Lantana camara), habitat degradation from feral goat browsing, persistent disturbance of nests and roosts, pesticide...
