Palmito

Palmito State Park (Parque Estadual do Palmito, PEP) is a coastal Atlantic Forest conservation unit in the municipality of Paranaguá, on the coastal plain of Paraná, Brazil. Covering approximately 1,782 hectares, it protects a mosaic of lowland dense ombrophilous forest, arboreal and herbaceous restinga, and mangrove within the urban perimeter of Paranaguá, roughly 70 km from Curitiba. ^[1] The area was originally protected in June 1998 and reclassified as a full Parque Estadual in 2017 under decree 7,097. The park is managed by the Instituto Água e Terra (IAT), with its name referencing the juçara palm (Euterpe edulis), historically harvested for heart of palm. The park safeguards representative coastal-plain ecosystems, offers accessible trails near a major port city, and plays a role in protecting mangroves and restinga that buffer the Paranaguá estuary.

The park's mix of forest, restinga and mangrove supports diverse coastal wildlife. Mammals include capuchin and howler monkeys, coatis, agoutis, capybaras and small wild cats, along with opossums and armadillos in the forest interior. The mangrove and estuarine margins are especially important for crabs, mollusks and juvenile fish that use the tidal channels as nursery habitat. ^[1] Birdlife is abundant, with herons, egrets, kingfishers and rails in the wetlands, and toucans, tanagers and hummingbirds in the forest canopy. Reptiles and amphibians thrive in the humid lowland environment. The park's proximity to the Paranaguá estuarine complex links it to a broader system of coastal wetlands, making it a valuable refuge for species dependent on the interface between mangrove, restinga and Atlantic Forest.

Palmito protects a representative sample of Paraná's coastal-plain vegetation, dominated by lowland dense ombrophilous forest (floresta ombrófila densa das terras baixas) together with arboreal and herbaceous restinga on sandy soils and mangrove along tidal channels. ^[1] More than 300 plant species have been recorded, including species rare or threatened in Paraná. The forest is named for the juçara palm (Euterpe edulis), whose overharvesting for heart of palm the park was partly created to curb. Mangrove formations feature typical species such as Rhizophora mangle, Laguncularia racemosa, Avicennia and the associated Conocarpus erectus. Restinga vegetation grades from herbaceous pioneer communities on the sand to denser shrubby and arboreal stands, forming a gradient that reflects the coastal plain's soils and hydrology.

The park lies on the Paraná coastal plain (planície litorânea), a low-lying belt of Quaternary sediments between the Serra do Mar mountains and the Atlantic Ocean. ^[1] Its terrain is composed of marine and fluvial-marine deposits—sands, silts and organic muds—laid down as sea levels fluctuated during the late Quaternary. The sandy substrates support restinga vegetation, while fine muddy sediments in tidally influenced channels form the substrate for mangroves. Elevations are near sea level and drainage is heavily influenced by tides from the Paranaguá estuarine complex. This flat, waterlogged geological setting, distinct from the crystalline rocks of the nearby Serra do Mar, gives the park its characteristic mosaic of well-drained sandy plains and saturated estuarine flats.

The park has a humid subtropical to tropical coastal climate, strongly influenced by the Atlantic Ocean and the nearby Serra do Mar, which forces moist air upward and produces heavy rainfall. The Paraná coast is among the wettest parts of the state, with annual precipitation commonly exceeding 2,000 mm and no strong dry season; the wettest months fall in summer, from December to March. Temperatures are warm and humid year-round, with summer highs often around 30°C and mild winters that rarely see frost near sea level. ^[1] High humidity and abundant rain sustain the lush lowland forest and mangroves. Visitors should be prepared for rain in any season and for warm, humid conditions and biting insects, particularly in the wetter summer months.

The Paraná coast around Paranaguá is one of the oldest areas of European settlement in southern Brazil, with Paranaguá founded in the 17th century as a port and gold-mining centre. Long before that, the coastal plain was inhabited by Indigenous peoples, including Tupi-Guarani groups and earlier populations who left extensive shell middens (sambaquis) along the estuary. ^[1] Traditional coastal communities (caiçaras) later relied on fishing, small-scale farming and the harvesting of forest products, including heart of palm from the juçara palm that gives the park its name. The intensive extraction of palmito and the pressures of a growing port city degraded surrounding forests, providing the historical backdrop against which the park was created to protect a remnant of coastal-plain ecosystems.

The area was first protected in June 1998 as Floresta Estadual do Palmito, with the primary aim of combating illegal harvesting of the juçara palm and providing sustainable management of coastal-plain forest. ^[1] In 2017, Governor Beto Richa upgraded the unit to a full Parque Estadual via decree 7,097, expanding and strengthening its integral protection status. Managed by the Instituto Água e Terra (IAT), Paraná's environmental agency, the park oversees protection, research, mangrove recovery projects and public use. Positioned within the urban perimeter of Paranaguá, the park has become an accessible green space for environmental education and recreation, while contributing to the conservation of the estuarine ecosystems that support the region's fisheries and coastal biodiversity.

The park offers a network of walking and cycling trails through lowland Atlantic Forest, restinga and toward mangrove areas, making it a popular destination for residents and visitors of Paranaguá. Interpretive trails allow observation of the juçara palm, coastal-plain flora, birdlife and the transition between forest and estuarine environments. ^[1] Because it lies within the city's urban perimeter, the park is easily reached and used for hiking, nature study and recreational running events organized by the IAT. Its combination of accessible trails, diverse coastal ecosystems and proximity to the port city makes Palmito a valued urban conservation area, showcasing mangrove and restinga habitats that are otherwise difficult to experience on foot in the region.

Palmito State Park is located within the urban perimeter of Paranaguá, on the Paraná coast, about 70 km from Curitiba via the BR-277 highway. ^[1] Its accessibility makes it one of the more visitable of Paraná's coastal conservation units, with trails suited to walking and cycling. The park is managed by the Instituto Água e Terra (IAT), which coordinates visitation, trail maintenance and periodic activities such as ecological races and mangrove restoration. Visitors should confirm current opening hours and access arrangements with the IAT, as coastal parks may adjust schedules for weather or management needs. Paranaguá provides full urban services, lodging and transport connections, serving as the practical base for visiting the park.

Palmito State Park protects a threatened mosaic of lowland Atlantic Forest, restinga and mangrove on Paraná's densely used coastal plain. ^[1] Its conservation priorities include recovering degraded mangrove areas—an ongoing IAT focus—curbing illegal harvesting of the juçara palm, and buffering the Paranaguá estuary against urban and port-related pressures. Mangroves within and around the park provide nursery habitat for fish and crustaceans, filter coastal waters and protect shorelines, delivering ecosystem services vital to local fisheries. ^[2] Managed by the Instituto Água e Terra, the park combines enforcement, restoration and environmental education, using its urban location to build public support for coastal conservation. Sustained protection here is important both for regional biodiversity and for the ecological health of one of Brazil's major port estuaries.
