Project Overview

The Fairfax County Urban Biodiversity Dashboard was developed as a personal initiative alongside my freelance work, driven by my interest in urban wildlife patterns and data visualization. This project transforms iNaturalist observation data into actionable insights, demonstrating how public datasets can be leveraged to understand local biodiversity patterns.


Using the iNaturalist API and modern web technologies, this platform creates an interactive window into Fairfax County's urban ecosystem, helping researchers, conservationists, and the public track and understand wildlife patterns, habitat health, and biodiversity trends in our developing urban landscape.

Credits

This project would not be possible without the dedicated community of citizen scientists contributing their observations to iNaturalist. Their daily efforts to document and share wildlife sightings form the foundation of this visualization platform.

Special recognition goes to the diverse wildlife of Fairfax County - from the smallest pollinator to the largest predator - whose presence enriches our urban ecosystem and reminds us of the importance of conservation in our developing landscapes.

The project utilizes protected species listings from the U.S. Fish and Wildlife Service's ECOS database, while invasive species data is sourced from Fairfax County Public Works, the Virginia Invasive Species Council, and the Virginia Department of Conservation and Recreation. Pollinator identification was made possible through careful filtering of known pollinating species genera, and the geographic analysis relies on the Fairfax County Boundary dataset for precise spatial filtering.

Data for this project is sourced from iNaturalist, a joint initiative by the California Academy of Sciences and the National Geographic Society. The platform's commitment to open data and community science has been instrumental in making urban wildlife research more accessible to everyone.
