GenEst is an R software package for estimating bird and bat fatalities at wind and solar power facilities. Mortality estimation requires five data files:

  1. searcher efficiency field trial results (SE),
  2. carcass persistence field trial results (CP),
  3. schedule for periodic carcass surveys (SS),
  4. fraction of total carcasses falling in the searched area at each unit searched or density-weighted proportion (DWP), and
  5. summary data from the carcass surveys (CO), including unit and search date of each carcass discovery along with values of other, optional covariates or carcass characteristics

Data sets can be uploaded under the Data Input tab. Formats are explained in the user guide. Example data sets are available for loading into GenEst under the Example Data tab.


Analysis involves several steps:

  • uploading data---click the Data Input tab,
  • entering General Input parameters---click the Analyses tab,
  • fitting searcher efficiency and carcass persistence models--- click the Searcher Efficiency and Carcass Persistence tabs, and
  • estimating total mortality and splitting mortality estimate by various subcategories (such as species or sector or season) as desired---click the Mortality Estimation tab

Example data sets


Wind---Cleared plots, bats + birds

Wind---Road and pad searches, bats + birds

Wind---Road and pad searches, bats

Solar---Power tower

Solar---Photovoltaic (PV)

Solar---Trough
