A Living River, Deeply Rooted

The Little River is one of Miami-Dade’s four original natural rivers, flowing from its historic Everglades headwaters to Biscayne Bay. Its extraordinary original landscape included freshwater springs, six-foot rapids, hardwood hammocks, and biodiverse mangrove forests.

Its banks also preserve thousands of years of human history. The El Portal Archaeological Zone along the river’s north bank includes significant Indigenous sites, including a burial mound and village area. Across the water, archaeological work near Pelican Harbor uncovered evidence of another former Tequesta settlement, including pottery fragments and other artifacts. Together, these discoveries reveal an interconnected cultural landscape extending across both sides of the Little River—long before modern property lines and municipal boundaries divided the surrounding land. The river provided freshwater, food, transportation, wildlife, and a vital connection between the inland wetlands and Biscayne Bay—many of the same natural resources and ecological connections that remain important today.

Today, the Little River remains a living river and wildlife corridor, of vital retained and reclaimed natural banks, living shorelines, mature native canopy, and riparian vegetation. The root systems of shoreline trees and vegetation help stabilize the banks, reduce erosion, and filter runoff, while the layered canopy, understory, and shoreline provide essential habitat for many species of birds and a wide range of other wildlife. The Village of El Portal, which borders the river along its north bank, is designated as a bird sanctuary.

As a direct, tidally connected tributary to Biscayne Bay, the Little River also creates an important estuarine transition where fresh and salt water meet, supporting aquatic life and linking the health of the river to the health of the Bay. As natural riverfront habitat becomes increasingly scarce and fragmented across urban Miami-Dade, these living shorelines provide vital refuge and sustain ecological functions essential to both the river and Biscayne Bay.

Protecting them means preserving essential wildlife habitat and an extraordinary connection between the Everglades, Miami’s earliest history, and Biscayne Bay.

The Little River is a living habitat corridor connecting inland waterways with Biscayne Bay. Its waters and natural shorelines support the federally threatened Florida manatee and American crocodile.

Manatees use the river throughout the year to rest, feed, seek freshwater, nurse and care for calves, and move between the river and the Bay. Naturally sloped shorelines, unlike vertical seawalls, preserve the shallow-water transition where native shoreline plants and submerged aquatic vegetation can grow and provide essential forage. This increasingly vital food resource is especially important amid the loss of seagrass elsewhere in Biscayne Bay. Regular documented sightings of the American crocodile also demonstrate its continued use of this reach as habitat and refuge.

Natural riverbanks, mature tree canopy, shallow waters, and connected aquatic habitat also provide food, shelter, and passage for migratory and wading birds, fish, turtles, and a wide range of other wildlife. Vegetated shorelines help absorb nutrients from stormwater runoff, improve water quality, reduce erosion and wave impacts, and sustain habitat throughout the river ecosystem.

Protecting the Little River means preserving and restoring the entire living system—not only the water, but also the limited remaining natural shorelines, shallow-water habitat, tree canopy, water quality, food sources, and interconnected habitat that wildlife depends upon in the heart of an increasingly urban region.

Little River’s natural banks, living shorelines, mature trees, soils, and surrounding vegetation form part of Miami’s natural climate infrastructure. Deep, established root systems stabilize riverbanks and hold soil in place, while healthy, permeable soils absorb rainfall, slow stormwater runoff, and reduce the amount of water flowing toward nearby homes and streets. Mature tree canopies provide shade and cooling, reduce extreme heat, support wildlife, and help sustain the river’s interconnected habitat.

Natural shorelines provide space for floodwaters to spread, slow, and be absorbed, while filtering runoff before it enters the river. Together, these living systems support a healthy river ecosystem and provide natural protection for surrounding communities. Replacing them with seawalls and other hardened structures can sever the connection between land and water, eliminate vegetation and natural flood-storage capacity, degrade habitat and water quality, and redirect water and erosive energy toward neighboring or downstream properties.

The Little River Adaptation Action Area Plan, developed by Miami-Dade County with local communities and government partners, recognizes the area’s vulnerability to flooding, sea-level rise, extreme heat, and water-quality challenges.

The environmental importance of the river corridor is also recognized in the Village of El Portal’s Comprehensive Plan and Zoning and Land Development Code. The Comprehensive Plan calls for retaining Little River’s limited natural waterfront stretch, preserving and mitigating its natural banks wherever possible, and improving the river’s environmental quality. Section 24-19 of the Village Code—titled “Environmentally Sensitive Areas”—requires existing natural native vegetation to be retained to the maximum extent feasible and establishes specific protections for natural vegetation on properties abutting the river.

Together, these plans and protections support natural-bank preservation, expanded green space, improved stormwater management, and other resilience measures intended to reduce risk and strengthen the communities surrounding Little River.

Preserving and restoring Little River’s natural banks, mature trees, living shorelines, and connected green spaces supports these resilience goals. 

Protecting these natural systems helps the river withstand heavier rainfall, flooding, extreme heat, storms, and rising water while safeguarding wildlife and the people who live nearby.
