These data represent capture histories for humpback chub (Gila cypha) that spawn in the Little Colorado River (LCR) from 2009-2017. Capture histories pertain to size class (<150mm total length [TL], 150-199mm TL, 200-249mm TL, and >250mm TL) and spatial location (the juvenile chub monitoring [JCM] reach in the Colorado River [63.4-65.0 river miles downstream of Lees Ferry], lower LCR [0-13.56 km upstream of Colorado River confluence], and upper LCR [13.57-17.9 km upstream of Colorado River confluence]).

Conclusions: In fragmented watersheds, macrohabitat attributes measured at the patch scale were far more effective in predicting trout translocation success than measurements taken at the landscape scale Thresholds/Learnings: As a course filter indicator of cutthroat trout translocation success, the study found that translocations have a greater than 50% chance of fruitful establishment in watersheds >14.7km2 in area. Synopsis: This study aimed to identify stream-scale and basin-scale macrohabitat attributes limiting successful translocation and persistence of native cutthroat trout populations in fragmented landscapes along the Rio Grande. The study developed models of habitat attributes measured at two scales...
This project integrates fire risk models, species distribution models (SDMs) and population models with scenarios of future climate and land cover to project how the effects of climate-induced changes to species distributions and land use change will impact threatened species in fire-prone ecosystems. This project also identifies and prioritizes potential management responses to climate change (e.g. assisted colonization, fire management, land protection, dispersal corridors). Anticipated products include: 1) maps (digital and hard copy) of habitat suitability under current and future climate change, current and future projected urban growth and combinations of climate change and future projected urban growth, under...

Translocations of greater sage-grouse (Centrocercus urophasianus) have been attempted in 7 states and one Canadian province with very little success. To recover a small remnant population and test the efficacy of sage-grouse translocations, we captured and transported 137 adult female sage-grouse from 2 source populations to a release site in Strawberry Valley, Utah, USA, during March-April 2003-2005. The resident population of sage-grouse in Strawberry Valey was approximately 150 breeding birds prior to the release. We radiomarked each female and documented survival, movements, reproductive effort, flocking with resident grouse, and lek attendance. We used Program MARK to calculate annual survival of translocated...

As grazers, sea urchins are keystone species in tropical marine ecosystems, and their loss can have important ecological ramifications. Die-offs of urchins are frequently described but their causesare often unclear, in part because systematic examinations of animal tissues at gross and microscopic level are not done. In some areas, urchins are being employed to control invasive marine algae. Here we describe the pathology of a mortality event in Tripneustes gratilla in Hawaii where urchins were being translocated to control invasive algae. Although we did not determine the cause of the mortality event, our investigation suggests that animals died from inflammation of the test and epidermal ulceration followed by...

These data were compiled for a study evaluating if rare or endangered fishes (e.g., Humpback Chub and Bonytail) can be transported in a shipping bag with 1-L of water and minimal sedative into remote locations. There were two components (laboratory trials and a field trial) of the study conducted in 2014 and 2017. Laboratory trials were conducted at the Rocky Mountain Research Station in Flagstaff, Arizona to evaluate three sedatives: AquaCalm, Tricaine-S, or Aqui-S 20E. Pilot trials were conducted with five fish (Bonytail) placed in a bag, where induction/recovery times, level of sedation, and fate after release were monitored for fish exposed to a sedative. Fish density increased to 20 fish (Bonytail and Humpback...

These data include encounter histories, nest attempts, hatched egg counts, brood counts, time-varying matrices, survival statistics, and lek counts, all used in an integrated population model (IPM) to determine the status of a population of translocated Columbian sharp-tailed grouse (Tympanuchus phasianellus columbianus; CSTG) in Nevada. Sharp-tailed grouse were translocated to a remote site in Nevada starting in 2013 through 2017. These data support the following publication: Mathews, S.R., ​Coates, P.S., Prochazka, B.G., Espinosa, S.P., and Delehanty, D.J., 2021, Offspring of translocated individuals drive the successful reintroduction of Columbian Sharp-tailed Grouse in Nevada, USA, Ornithological Applications,...
Translocations are a common conservation technique; however, the feasibility and success of translocations are evaluated rarely. We translocated 57 trumpeter swans (Cygnus buccinator) from Idaho to previous termUtahnext term during 1996 to encourage migration to more southern wintering areas. We evaluated the feasibility and success of the translocation by studying biological and socio-political criteria prior to and during the translocation. Lack of support from governmental and non-governmental agencies did not allow additional translocations in subsequent years. Additional releases are needed, however, to increase the probability of swan returns to the release area. Our evaluation explores the possibility that...

This database contains demographic and movement variables for 158 adult Agassiz's desert tortoises (Gopherus agassizii) translocated from the National Training Center (NTC), Fort Irwin, in the central Mojave Desert, California, in spring of 2008 and monitored through fall of 2018. The tortoises, fitted with radio transmitters, were translocated to plots south of Fort Irwin and followed monthly until fall of 2018, when transmittered were removed, and the project was ended. The database consists of unique identification numbers of the tortoises, sex and size, dates, details of locations, and status of the tortoises. These data support the following publication: Mack, J.S. and Berry, K.H., 2023. Drivers of survival...

This dataset comprises high-resolution geotif files representing various aspects of the ʻākohekohe (Palmeria dolei) potential habitat on the Island of Hawaiʻi. It includes a habitat suitability map showing average suitability scores, a map of homogenous forested areas (HFAs) depicting clusters with consistent suitability scores, and a map of pixel-wise standard deviation across habitat suitability models. These maps were generated through a comprehensive analysis using lidar-based metrics, offering detailed insights into the habitat preferences of ʻākohekohe.

Maintenance of genetic diversity is important for conserving species, especially those with fragmented habitats and/or ranges. In the absence of natural dispersal, translocation can be used to achieve this goal. However, the long-term impacts from translocation can be expensive and difficult to evaluate. This dataset is used to evaluate genetic change as a result of translocation and represents samples collected before and after translocations were conducted.

Prior to the initiation of translocation efforts in 2017, Pacific lamprey (Entosphenus tridentatus) were last documented in the Okanogan river subbasin in 2010. It appears as if lamprey were extirpated in the Okanogan subbasin some time shortly after that. However, until 2017, monitoring and management actions for lamprey were minimal in the Okanogan subbasin. This lack of monitoring has resulted in a large gap in understanding of the recent historical status of Pacific lamprey distribution throughout the Okanogan subbasin. Recent (beginning in 2017) translocation efforts have helped to rebound or reestablish lamprey in the Okanogan subbasin. Analysis of archived eDNA samples from the Okanogan river and its tributaries...
