Location: Guayas Province  Map

Area: 350.41 km2

 

Churute Mangroves Ecological Reserve is located in Guayas Province of Ecuador. These mangrove forest of Churute Mangroves Ecological Reserve covers an area of 350.41 km2. The closest large settlement is the city of Guayaquil located about 40 km (25 miles) from the entrance to Churute Mangroves. Although the reserve offers a network of hiking trail, the best way to explore the mangrove forest is by canoe. Aquatic birds, many species of crustaceans and many tortoises are most abundant on the border between water and mangrove forests. Keeping it quiet and restrain from any sudden movements will allow to approach fauna of this Ecuadorian Ecological Reserve fairly close.

 

Tourist tips

Key Highlights and Biodiversity
Mangroves: Home to five of Ecuador’s seven mangrove species, dominated by red mangroves (Rhizophora mangle). The intricate root systems support a rich ecosystem, filtering water, preventing erosion, and nurturing marine life.
Wildlife:
Birds: Exceptional for birdwatching (nearly 300 species reported). Common sightings include roseate spoonbills, wood storks, herons (Cocoi, little blue), kingfishers, ibis, cormorants, ospreys, magnificent frigatebirds, snail kites, and the horned screamer. Water levels peak around January for more waterfowl.
Mammals: Mantled howler monkeys (often seen on the “Howler Trail”), white-throated capuchin monkeys, iguanas, raccoons, armadillos, anteaters, and possibly sloths.
Other: American crocodiles/caimans, crabs (especially red mangrove crabs harvested at low tide), shrimp, tortoises, and various insects.

Flora: Mangroves along waterways; dry forests with oak, ebony, silk-cotton (ceiba), balsa trees; abundant orchids and bromeliads.

Many tours combine the reserve with a visit to a local cacao farm for a chocolate-making demonstration and lunch, adding cultural depth.

How to Get There
From Guayaquil: Most visitors join organized day tours (recommended for convenience, guides, and transport). Private or small-group tours typically include hotel pickup, last 1–1.5 hours one way. Public buses from Guayaquil’s Terminal Terrestre head east; ask to be dropped near the reserve entrance (around Km 49 on the Guayaquil-Machala highway), then take a taxi or arrange local transport.
Self-drive: Feasible but less common; follow signs toward Naranjal or Posorja area. A visitor center and dock provide access points.

Best Time to Visit
Dry season (roughly June–December) offers better trails and fewer mosquitoes, though wildlife viewing remains good year-round.
Wet season (January–May) brings higher water levels in lagoons (great for birds) but more rain and insects.
Tide timing matters for boat rides and crab activity—tours often align with optimal conditions. Mornings are generally best for cooler temperatures and active wildlife.

Main Activities and Tourist Tips
Canoe/Boat Ride through Mangroves (1–2 hours typical):
Motorized canoes navigate estuaries and channels, gliding under natural “tunnels” formed by mangrove roots. Guides explain the ecosystem, symbiosis with crabs, and point out birds and wildlife.
Tip: Bring binoculars and a zoom camera. Stay quiet for better sightings. Life jackets are usually provided.

Hiking Trails:
Sendero El Aullador (Howler Monkey Trail): Popular ~1.4 km interpretive trail through tropical dry forest. Good chance to see (and hear) howler monkeys, birds, and plants. Moderate difficulty; can be muddy.
Other short trails exist; only a few are designated for tourism. A raised boardwalk or interpretive paths may be available near the entrance.
Tip: Wear sturdy, closed-toe hiking shoes or water sandals that dry quickly. Trails can be slippery or uneven.

Wildlife Watching & Photography: Focus on lakes (e.g., El Canclón or Churute) for aquatic birds and at salt flats for shorebirds.
Visitor Center: Start here for maps, info on flora/fauna, and orientation. Local guides (often required or highly recommended) enhance the experience.

Typical Full-Day Itinerary (from Guayaquil tours):
Morning pickup → Canoe ride → Hike → Optional cacao farm visit/lunch (learn about harvesting, processing, and tasting) → Return by afternoon/evening.

Practical Tips
Entry & Costs: Entry fee around $10–15 USD (older reports mention ~$13); local guide ~$50 (may be per group). Full-day tours from Guayaquil typically range $70–$250+ per person depending on group size/private vs. shared, inclusions (transport, guide, lunch). Book via reputable operators like those on Viator, Civitatis, or local eco-tour companies.

What to Bring:
Insect repellent (mosquitoes can be intense—apply thoroughly, especially on legs).
Binoculars, camera, hat, sunglasses, sunscreen.
Lightweight long sleeves/pants for sun/insect protection.
Sturdy shoes, rain jacket/poncho (weather can change), water bottle, snacks.
Passport/ID copy.

Health & Safety: Moderate physical fitness needed for hikes. Not wheelchair accessible. Watch for slippery surfaces, wildlife (don’t feed or approach closely), and sun exposure. Drink plenty of water.
Respect the Environment: Follow “leave no trace.” Do not disturb wildlife or mangroves. Support conservation by using local guides and eco-friendly tours.
Language: Many local guides speak Spanish primarily; English-speaking guides are available via tours.
Accessibility & Limitations: Limited infrastructure; it’s a natural reserve, not heavily developed. Surveillance can be an issue in some areas, but visitor zones are generally safe.

 

History

Pre-Columbian and Indigenous History
The area has a deep human history spanning over 4,000 years. Archaeological evidence shows settlement by ancient cultures including Valdivia, Chorrera, Guangala, Jambelí, Guayaquil, and Milagro. These groups left behind remains such as camellones (raised agricultural platforms on flood-prone soils) and tolas (earthen mounds used for burials, housing, ceremonies, or lookouts) in the plains, hillsides, and around Laguna El Canclón.
These pre-Columbian societies relied on the rich estuarine resources—fish, shellfish, crabs, and mangroves—for sustenance and likely engaged in early forms of resource management. The region’s mangrove-human interactions in the broader neotropics represent the vast majority of such history, with mangroves playing key roles in livelihoods long before European contact.
Later Indigenous and local communities continued traditional uses, including fishing, crabbing (especially the red crab or guariche, Ucides occidentalis), and agriculture. Several communities (around 11 noted in some accounts) were already present when formal protection began, and their ancestral rights have been largely respected, with special permits for sustainable resource use.

20th Century: Establishment and Early Protection (1970s–1990s)
The reserve was officially created on July 26, 1979, via Acuerdo Interministerial No. 322 (published in Registro Oficial No. 69 on November 20, 1979). It was initially around 35,000–49,000+ hectares (sources vary slightly on exact initial figures, often cited near 49,383–49,984 ha), encompassing mangroves, dry forests, and hills. It was one of the first protected mangrove areas on Ecuador’s continental coast and the only one in the national system focused on this ecosystem at the time.
Boundary adjustments followed:
Acuerdo Ministerial No. 513 (December 23, 1987) for modifications.
Acuerdo Ministerial No. 0376 (July 23, 1992) for expansion and redefinition of boundaries.
In 1990, it was designated a Ramsar Site (Wetland of International Importance) due to its extensive aquatic environments, supporting diverse habitats and species.
Early management involved collaboration between institutions like INEFAN (Instituto Ecuatoriano Forestal y de Áreas Naturales y Vida Silvestre) and organizations such as Fundación Natura, leading to management plans (e.g., Phase 1 proposals in the mid-1990s) that addressed zoning, socio-economic issues, and threats like land tenure conflicts arising from the 1992 expansion.

Biodiversity and Ecological Significance
The reserve protects ~60% mangrove forest (five of Ecuador’s seven mangrove species, dominated by red mangrove) alongside dry forests, garúa (mist) forests on hills, estuaries, and lagoons. It supports rich fauna: howler monkeys, crocodiles, caimans, jaguars, anteaters, numerous birds (over 300 species, including migratory and emblematic ones like the canclón), and marine/estuarine life critical for fisheries.
It serves as a refuge for threatened species and a nursery for commercially important marine life.

Post-Establishment Challenges and Conflicts (1990s–Present)
Despite protection, the reserve has faced ongoing pressures typical of coastal areas near a major city like Guayaquil:
Shrimp farming (aquaculture): Major driver of mangrove loss. Farms existing before 1979 could continue but not expand; post-1979 ones were supposed to be removed. Illegal expansion, deforestation, and pollution from effluents persist. In 2008, an executive decree required eviction and reforestation of illegal ponds, but enforcement has been inconsistent.
Land tenure and human settlements: Expansion in 1992 created conflicts with local possessors and agricultural expansion. Communities rely on crabbing and fishing; ~2,000 families (organized in associations) depend on the mangroves.
Other threats: Illegal logging, poaching, fires, overgrazing, pollution, invasive species, and weak enforcement due to limited resources (staff cuts, equipment issues like boats). Limits are not always physically marked, leading to “no man’s land” perceptions.

Local crabbers and fishers have become key advocates, denouncing violations and sometimes assisting patrols. Institutional changes (e.g., closure of the Undersecretariat for Coastal Marine Management around 2020) and budget constraints have complicated responses.
Carbon stock studies show relative stability in recent years (2015–2021), underscoring its value for climate mitigation.

 

Geography

Location and Size
Geographic position: Approximately 40–50 km (25–30 miles) southeast of Guayaquil, near the towns of Posorja, Naranjal, and Río Taura. Coordinates center around 2°30′32″S 79°44′38″W. It lies in the lower basins of rivers flowing into the Gulf of Guayaquil, part of the broader Guayas River estuary system.
Area: Sources vary slightly due to boundary ambiguities, but it spans roughly 49,383–55,212 hectares (about 494 km² or ~135 square miles), with around 60–67% consisting of mangrove swamp/estuary.
Accessibility: About 45 minutes to 1 hour from Guayaquil by road, with access points along highways like Durán-Boliche. It includes river ports like Soledad Grande for boat entry.

Topography and Landforms
The reserve is not flat mangrove-only; it features diverse relief:
Mangrove and estuarine lowlands: Dominate ~87% of the area (low-lying, tidal flats, canals, and islands at near sea level). These form a complex network where freshwater meets seawater.
Coastal hills (Cordillera de Churute): A small chain of hills rising from ~10–700 meters above sea level (masl), occupying ~11% of the reserve. Key hills include Mate, Cimalón, Perequete Chico/Grande, Pancho Diablo, Mas Vale, and Pechuga de Niño. Higher elevations often experience fog ("garúa"), supporting more humid vegetation.
Lakes and wetlands: Includes Laguna El Canclón (a ~800-hectare freshwater lake formed by rainfall, with smaller connected lakes) and associated alluvial plains (~2% of the area) in the lower Guayas basin.
Other features: Salt flats, tidal channels, and some archaeological sites (e.g., ancient mounds from cultures like Valdivia along the highway).
The terrain transitions from tidal mudflats and dense mangrove tangles near the water to drier foothills and steeper, fog-influenced slopes inland.

Hydrology and Water Dynamics
Estuarine system: A brackish zone where saline ocean water mixes with freshwater from the Taura (main source, formed by Boliche and Culebra rivers), Churute, Cañar, and Naranjal rivers. This creates dynamic salinity gradients, tidal canals, islands, and sediment-laden waters.
Tides and sediments: Strong tidal influence; mangroves thrive in the intertidal zone. Rivers deposit sediments, and flocculation (from salt-freshwater mixing) adds more, building the muddy substrate.
Lakes: El Canclón is primarily rain-fed, contrasting with the brackish estuarine areas.
Climate influence: Tropical megathermal climate with distinct wet (Jan–May, peak rainfall) and dry (Jun–Dec) seasons. Average temperature ~28°C (82°F); annual rainfall ~960 mm in hills (less at sea level), but highly variable with El Niño events, which can cause heavy flooding.
These dynamics make the area highly productive ("nurseries of the ocean") but also challenging for biodiversity due to fluctuating conditions.

Vegetation and Ecosystems
Mangroves (~60%+ of the reserve): Home to five of Ecuador’s seven mangrove species, including red (Rhizophora mangle), white (Laguncularia racemosa), black (Avicennia germinans), jelí/button (Conocarpus erectus), and crawling (Rhizophora racemosa). Structural types range from tall forests (>15m) to shrubby forms. They act as "blue carbon" sinks, coastal buffers against erosion/floods/tsunamis, and nurseries for marine life.
Dry and humid forests on hills: Deciduous and semi-deciduous forests with species like oak, ebony, silk-cotton (ceibo), balsa, Tabebuia chrysantha (golden trumpet tree), and others. Epiphytes (orchids, bromeliads) are common. Higher slopes have premontane evergreen elements and ferns.
Other: Lowland shrublands, herbal marshes (e.g., water hyacinth), and secondary forests recovering from past disturbances.

Ecological and Geographic Significance
As a Ramsar wetland site and tentative World Heritage candidate, it protects rare Pacific South American mangroves (one of the best-developed and publicly accessible). It serves as a natural flood barrier for nearby areas (Guayaquil is vulnerable to flooding), supports carbon sequestration, and sustains local fisheries (e.g., red mangrove crabs).
Note on challenges: Boundaries are not always physically marked, leading to pressures from shrimp farming, agriculture, and illegal activities, though it remains a vital protected area.
