Parayko, N. W., J. W. Ng, J. Marley, R. S. Wolach, T. I. Wellicome, and E. M. Bayne. 2021. Response of Ferruginous Hawks to temporary habitat alterations for energy development in southwestern Alberta. Avian Conservation and Ecology 16(2):17. https://doi.org/10.5751/ACE-01958-160217
Highlights
Habitat loss and degradation by anthropogenic activities is a leading cause of global biodiversity decline (Pimm and Raven 2000)
Generalized linear mixed models were used to test for five responses: (1) Ferruginous Hawk nest density, (2) nest success, (3) productivity, (4) nest site re-occupancy, and (5) changes to nesting raptor and raven community composition
The collective results of our 7-year study suggest a limited influence of transmission line changes to Ferruginous Hawk nesting structures on nest success, productivity, and re-occupancy
Summary
Habitat loss and degradation by anthropogenic activities is a leading cause of global biodiversity decline (Pimm and Raven 2000). Changes to landscapes are increasingly caused by energy development (McDonald et al 2009) with a 28% increase in global energy demand projected over the 22 years (USEIA 2017). To meet this demand, the greatest proportional increase in energy production is predicted to come from renewable energy. In the United States, over 200,000 km of new land is expected to be developed for energy-related projects by 2035 (McDonald et al 2009) With these energy projects, associated infrastructure such as transmission lines often requires updating to support higher capacities.
