The Manglaralto Estuary is a mangrove wetland at the mouth of the river (estero) that runs through Manglaralto town on the Ruta del Spondylus. It is notable for containing one of the last remnant stands of old-growth mangrove on this stretch of the Ecuadorian Pacific coast — a rarity in a region where mangroves have been extensively cleared for shrimp aquaculture and coastal development.
The Mangroves
Old-growth mangrove forest here reaches significant heights — mature red mangrove (Rhizophora mangle) and black mangrove (Avicennia germinans) trees form a canopy several metres above the water. The aerial root systems (prop roots and pneumatophores) create a dense, labyrinthine habitat below the waterline that serves as a nursery for juvenile fish, shrimp, crabs, and other marine organisms.
Mangroves are among the most carbon-dense ecosystems on the planet and provide critical shoreline protection against erosion and storm surge. The survival of this stand while surrounding areas have been cleared is attributed to the relative isolation of Manglaralto and the lower development pressure compared to the southern peninsula.
Wildlife
| Species group | Examples |
|---|---|
| Birds | Great blue heron, tricoloured heron, little blue heron, snowy egret, roseate spoonbill (occasional), mangrove yellow warbler, kingfisher, frigatebird overhead |
| Fish | Numerous juvenile species using the estuary as nursery habitat |
| Crustaceans | Blue crabs, mangrove crabs, snapping shrimp |
| Molluscs | Oysters attached to prop roots |
| Mammals | Occasional raccoon; bats roosting in the canopy at dusk |
Activities
Kayaking
The estuary is navigable by kayak or small boat at high tide. This is the best way to enter the mangrove channels and experience the interior of the forest. Kayak rentals are available in Manglaralto (ask at accommodation or locally). A guided paddle takes approximately 1.5–2 hours.
Birdwatching
The estuary is one of the better birdwatching locations on the Ruta del Spondylus. Early morning (before 8 AM) is best. Herons and egrets are present year-round; seasonal migrants pass through during the northern winter (October–April).
Walking
The edge of the estuary can be explored on foot from Manglaralto town. A path follows the river toward the sea. Note that the interior mangrove channels are only accessible by boat.
Conservation
The mangrove stand is informally protected by community awareness and by the lack of development pressure in Manglaralto. No formal protected area designation covers this specific estuary. The main threats are:
- Shrimp pond expansion further south along the coast
- Solid waste dumped into the estuary margin (a documented local issue)
- Climate-change-driven sea-level rise
Getting There
Manglaralto is on the E-15 (Ruta del Spondylus), approximately 50 km north of La Libertad. Buses from La Libertad run frequently throughout the day. The estuary is accessible from the village on foot.
