    "description": "The series was designed to assess the statistical power of detecting population declines in individual species counts linked to wind farm construction. Employing a methodology based on Generalized Linear Modelling (GLM) and randomization, the study used real count data from random sites by species, year, and month, generating hypothetical scenarios with a model-derived mean-to-variance ratio (P-scale factor). Through 1,000 randomization iterations and comparison of pre- and post-construction counts, the analysis determined the proportion of significant results using P value thresholds. The findings demonstrate that this approach provides robust estimation of statistical power for detecting site-level population declines, and it is recommended for use in similar ecological impact assessments involving temporal and spatial data.",
