Predictive model of avian electrocution risk on overhead power lines.

摘要: Electrocution on overhead power structures negatively affects avian populations in diverse ecosystems worldwide, contributes to the endangerment of raptor Europe and Africa, is a major driver legal action against electric utilities North America. We investigated factors associated with electrocutions so poles that are likely electrocute bird can be identified retrofitted prior causing mortality. used historical data from southern California identify patterns electrocution by voltage, month, year species most often killed our study area develop predictive model compared where an was known have occurred (electrocution poles) no (comparison poles). chose variables could quantified personnel little training ornithology or systems. Electrocutions were more common at distribution voltages (≤33 kV) during breeding seasons commonly reported after retrofitting program began. Red-tailed Hawks (Buteo jamaicensis) (n = 265) American Crows (Corvus brachyrhynchos) 258) electrocuted species. In model, 4 14 candidate required distinguish comparison poles: number jumpers (short wires connecting energized equipment), primary conductors, presence grounding, unforested unpaved areas as dominant nearby land cover. When tested sample not build distributed relatively normally across electrocution-risk values average risk higher for relative poles. Our reduce through proactive identification targeting high-risk retrofitting. Modelo Predictivo del Riesgo de Electrocucion Aves en Lineas Electricas Elevadas Resumen La electrocucion estructuras energia elevadas afecta negativamente poblaciones aves diversos ecosistemas todo el mundo, contribuye al riesgo rapaces Europa y es una causa importante accion contra empresas electricas Norte Investigamos los factores asociados con la para que postes posiblemente electrocuten ave sean identificados acondicionados antes causen mortalidad aves. Utilizamos datos historicos sur identificar patrones por voltaje, mes ano las especies mueren mas frecuentemente nuestra zona estudio desarrollar un modelo predictivo comparo se sabia habia ocurrido (postes electrocucion) hubo comparacion). Seleccionamos pudieran ser cuantificadas personal poco entrenamiento ornitologia o sistemas electricos. Las electrocuciones fueron comunes voltajes distribucion (≤33kV) durante epocas reproductivas reportadas comunmente despues comenzo programa acondicionamiento. electrocutadas Buteo jamaicensis Corvus brachyrhynchos 258). En predictivo, requirieron consideradas distinguir comparacion comparacion: numero puentes (cables cortos conectan equipo energizado), conductores primarios, presencia conexiones tierra deforestadas pavimentadas dominantes cobertura suelo cercana. Al probarlo muestra utilizados construirlo, nuestro distribuyo nomalmente valores e identifico promedio alto relacion poses comparacion. Nuestro puede usado reducir mediante identificacion proactiva riesgo.
