Solar and wind power development is increasing exponentially in the United States. However, these energy sources may affect wildlife, either directly from collisions with the turbine blades or photovoltaic arrays or indirectly from loss of habitat and migration routes. An important component to understanding the effects of these renewable energy projects on wildlife is accurate and precise...
FRESC's Wind Energy and Wildlife Team is lead by Manuela Huso. She and her team are involved in design and analysis of post-construction fatality monitoring studies as well as deterrent and curtailment studies at several wind-power generation facilities.
This research theme informs adaptive management and siting decsions in relation to bats at wind and solar power-generation facilities.
This research theme addresses several issues important in deriving accurate and precise estimates of fatality at wind and solar power-generation facilities.
GenEst user guide—Software for a generalized estimator of mortality
GenEst (Generalized Estimator) is a software tool for estimating the total number of individuals arriving in an area during a specific time period when their detection probability is unknown but estimable. Its development was motivated by the need to accurately estimate the total number of bird and bat fatalities occurring at wind and solar energy...Simonis, Juniper; Dalthorp, Daniel; Huso, Manuela; Mintz, Jeffrey; Madsen, Lisa; Rabie, Paul; Studyvin, Jared
GenEst statistical models—A generalized estimator of mortality
IntroductionGenEst (a generalized estimator of mortality) is a suite of statistical models and software tools for generalized mortality estimation. It was specifically designed for estimating the number of bird and bat fatalities at solar and wind power facilities, but both the software (Dalthorp and others, 2018) and the underlying statistical...Dalthorp, Daniel; Madsen, Lisa; Huso, Manuela; Rabie, Paul; Wolpert, Robert; Studyvin, Jared; Simonis, Juniper; Mintz, Jeffrey
Raptor interactions with wind energy: Case studies from around the world
The global potential for wind power generation is vast, and the number of installations is increasing rapidly. We review case studies from around the world of the effects on raptors of wind-energy development. Collision mortality, displacement, and habitat loss have the potential to cause population-level effects, especially for species that are...Watson, Richard T.; Kolar, Patrick S.; Ferrer, Miguel; Nygård, Torgeir; Johnston, Naira; Hunt, W. Grainger; Smit-Robinson, Hanneline A.; Farmer, Christopher J; Huso, Manuela; Katzner, Todd
Evidence of absence (v2.0) software user guide
Evidence of Absence software (EoA) is a user-friendly software application for estimating bird and bat fatalities at wind farms and for designing search protocols. The software is particularly useful in addressing whether the number of fatalities is below a given threshold and what search parameters are needed to give assurance that thresholds...Dalthorp, Daniel; Huso, Manuela; Dail, David

Mortality monitoring design for utility-scale solar power facilities
IntroductionSolar power represents an important and rapidly expanding component of the renewable energy portfolio of the United States (Lovich and Ennen, 2011; Hernandez and others, 2014). Understanding the impacts of renewable energy development on wildlife is a priority for the U.S. Fish and Wildlife Service (FWS) in compliance with Department...Huso, Manuela; Dietsch, Thomas; Nicolai, Chris
Wind energy development: Methods to assess bird and bat fatality rates post-construction
Monitoring fatalities at wind energy facilities after they have been constructed can provide valuable information regarding impacts of wind power development on wildlife. The objective of this monitoring is to estimate abundance of a super-population of carcasses that entered the area within a designated period of time. By definition, the...Huso, Manuela; Dalthorp, Daniel; Miller, T. J.; Bruns, Dawn
A framework for decision points to trigger adaptive management actions in long-term incidental take permits
Introduction The U.S. Fish and Wildlife Service (USFWS) has begun to issue incidental take permits (ITPs) to wind power companies to allow limited take of bird and bat species that are protected under the Endangered Species Act, the Bald and Golden Eagle Protection Act, or the Migratory Bird Treaty Act (Huso and others, 2015). Expected take rates...Dalthorp, Daniel; Huso, Manuela
Estimating wind-turbine-caused bird and bat fatality when zero carcasses are observed
Many wind-power facilities in the United States have established effective monitoring programs to determine turbine-caused fatality rates of birds and bats, but estimating the number of fatalities of rare species poses special difficulties. The loss of even small numbers of individuals may adversely affect fragile populations, but typically, few (...Huso, Manuela M.P.; Dalthorp, Daniel; Dail, David; Madsen, Lisa
Behavior of the Hawaiian Hawaiian Hoary Bat (Lasiurus cinereus semotus) at wind turbines and its distribution across the North Ko'olau Mountains, O'ahu
We studied the landscape distribution of endemic Hawaiian hoary bats (Lasiurus cinereus semotus) on the north Ko‘olau Mountains of O‘ahu, Hawai‘i, from May 2013 to May 2014, while simultaneously studying their behavior at wind turbines within the broader landscape. This research aimed to assess the risk that wind turbines pose to bats on the...Gorresen, P.M.; Cryan, Paul M.; Huso, Manuela M.P.; Hein, Cris D.; Schirmacher, Michael; Johnson, Jessica H.; Montoya-Aiona, Kristina; Brinck, Kevin W.; Bonaccorso, Frank
Mortality estimation from carcass searches using the R-package carcass: a tutorial
This article is a tutorial for the R-package carcass. It starts with a short overview of common methods used to estimate mortality based on carcass searches. Then, it guides step by step through a simple example. First, the proportion of animals that fall into the search area is estimated. Second, carcass persistence time is estimated based on...Korner-Nievergelt, Fränzi; Behr, Oliver; Brinkmann, Robert; Etterson, Matthew A.; Huso, Manuela M.

Behavior of bats at wind turbines
Wind turbines are causing unprecedented numbers of bat fatalities. Many fatalities involve tree-roosting bats, but reasons for this higher susceptibility remain unknown. To better understand behaviors associated with risk, we monitored bats at three experimentally manipulated wind turbines in Indiana, United States, from July 29 to October 1, 2012...Cryan, Paul M.; Gorresen, P.

Software to Estimate Bird and Bat Fatality at Wind Farms
Tool to Evaluate Wildlife Fatalities at Wind-Power Facilities
Simple counts of carcasses found at wind farms do not reflect actual fatalities because some are removed by scavengers, or are overlooked by or fall within areas inaccessible to searchers. Because the density of carcasses generally declines with distance from the turbine, the location and configuration of inaccessible areas can greatly affect the proportion of carcasses that might be missed....
