A previously published model of avian electrocution risk, “the 2014 model,” was developed by comparing power poles that electrocuted birds (electrocution poles; including 21 golden eagle Aquila chrysaetos electrocutions) to poles not known to have electrocuted birds (comparison poles).  The 2014 model produces pole-specific risk index scores between 0 and 1.  The scores rank relative risk so electric utilities can maximize conservation benefits per dollar spent by focusing retrofitting on poles with greatest risk.  Although the 2014 model was created from a study population of birds and poles in southern California, the 2014 model has potential to be used in managing a target population of raptors including golden eagles throughout the western United States.  Use beyond southern California is only appropriate if the study population is similar enough to the target population for the 2014 model to predict risk effectively.  To evaluate similarity, we examined five sources of evidence.  Two were the relative consistency in electrical safety codes for power poles and body sizes of golden eagles in the study and target populations.  Three more were consistency in structure-specific factors associated with 1) golden eagle electrocutions in other studies, 2) other avian electrocutions, and 3) previously unreported golden eagle electrocutions.  We found that although the study population in the 2014 model included relatively few golden eagles, data were sufficient to create a model that can be applied to a target population throughout the western United States.  The model can also be useful in helping determine equivalencies between pole types if utilities seek to compare benefits of retrofitting small numbers of high-risk poles to large numbers of low-risk poles.

Do So

Coherence of place often exists alongside irregularities in time in cycles, and chapter three turns to cycles linked by temporal markers. Ray Bradbury’s The Martian Chronicles (1950) follows a linear chronology and describes the exploration, conquest, and repopulation of Mars by humans. Conversely, Louise Erdrich’s Love Medicine (1984) jumps back and forth across time to narrate the lives of interconnected families in the western United States. Bradbury’s cycle invokes a confluence of historical forces—time as value-laden, work as a calling, and travel as necessitating standardized time—and contextualizes them in relation to anxieties about the space race. Erdrich’s cycle invokes broader, oppositional conceptions of time—as recursive and arbitrary and as causal and meaningful—to depict time as implicated in an entire system of measurement that made possible the destruction and exploitation of the Chippewa people. Both volumes understand the United States to be preoccupied with imperialist impulses. Even as they critique such projects, they also point to the tenacity with which individuals encounter these systems, and they do so by creating “interstitial temporalities,” which allow them to navigate time at the crossroads of language and culture.
