species-distribution

An R package to generate ecologically-informed species range maps from occurrence data with seamless GBIF integration

A reproducible ecological connectivity workflow using GBIF occurrence records, Natura 2000 protected area data, resistance surface modelling, and Omniscape connectivity analysis for conservation planning.

Leverages big data and machine learning for wildlife conservation using GBIF species data. PySpark is used for preprocessing, K-Means for clustering, and Decision Trees for habitat prediction. Tableau visualizes species distribution, biodiversity, and conservation insights.
