To most visitors, Canaveral National Seashore, or CANA, is experienced at ground level: beaches, dunes, sea oats, coastal scrub, hammocks, salt marshes, mangroves, open sky, and long stretches of shoreline.

But from a satellite view, the Seashore is seen from a different perspective.

A study published in 2024 used high-resolution satellite imagery to examine changes in vegetation cover between 2016 and 2023 across Cape Canaveral Barrier Island. The study included both protected areas within Canaveral National Seashore and areas near active rocket launch facilities at Kennedy Space Center and Cape Canaveral Space Force Station.

Using NASA Worldview satellite imagery, with a ground pixel size of about 2-3 meters, land cover changes were mapped across the Seashore. The main coastal habitat types included foredune and coastal strand, coastal scrub and maritime hammock, mangrove swamp, and coastal salt marsh.

These plant communities form the living mosaic of the barrier island.

Foredunes and coastal strands help protect the island’s ocean-facing edge. Scrub and hammock habitats support distinctive coastal plants and wildlife, including federally listed species, such as the Florida scrub-jay. Salt marshes and mangroves buffer the land from water, absorb wave energy, and provide important wetland habitat.

One of the most important parts of the study is that CANA served as a comparison site. Because the National Seashore is less developed than the nearby launch areas, it gave researchers a way to better understand which changes may be part of the broader natural coastal system, and which changes may be more closely tied to heavily altered areas.

During the period studied, the CANA landscape appeared comparatively stable when compared with areas near active launch sites. That does not mean Canaveral National Seashore is untouched by change. Like the rest of Florida’s barrier islands, it is still exposed to sea-level rise, storms, erosion, saltwater movement and warming temperatures.

Mangroves are expanding northward in many parts of Florida as severe freezes become less frequent. Coastal wetlands and uplands are expected to keep shifting as water levels, salinity, and disturbance patterns change. CANA is part of that larger story.

But the Seashore’s value lies partly in the fact that it remains one of the best places to observe these changes in a less-developed barrier island setting.

Canaveral National Seashore is not only a refuge for plants, wildlife and visitors. It is also a living benchmark for the future of Florida’s coastal barrier islands by serving as reference points. They help scientists ask and test questions. They help us understand what is changing, how fast it is changing, and why it matters.
