Araucaria moist forests
coniferous forest ecoregion of the Atlantic Forest Biome in South America
The Araucaria moist forests, officially classified as mixed ombrophilous forest (Portuguese: "Floresta Ombrófila Mista") in Brazil, are a montane subtropical moist forest ecoregion. The forest ecosystem is located in southern and in few areas of southeastern Brazil and parts of northeastern Argentina. The ecoregion is a southern portion of the Atlantic Forest. The ecoregion also includes select areas of open field called "campos de cima da serra" or "coxilhas" (highland fields).
Setting
The moist forests cover an area of 216,100 square kilometres (83,400 mi2), encompassing a region of mountains and plateaus in the Brazilian states of São Paulo, Paraná, Santa Catarina, and Rio Grande do Sul, and extending into Misiones Province of Argentina.
The ecoregion lies above 500 metres (1,600 ft), rising to 1,600 metres (5,200 ft) elevation on the high slopes of the Serra Geral.
The ecoregion is bounded by the Alto Paraná Atlantic forests to the north, west, and south, the Cerrado savannas and shrublands to the northeast, The Serra do Mar coastal forests to the east, and the Uruguayan savanna to the southwest.
Climate
The Araucaria moist forests have an oceanic temperate climate (Cfb), with frequent frosts during the winter months and considerable snowfalls (generally light) in the highest areas. Annual precipitation is high, ranging from 1,300 to 3,000 millimetres (51 to 118 in), without a dry season.
Flora
The ecoregion mostly consists of evergreen subtropical moist forests, with a canopy made up of the broadleaved trees Ocotea pretiosa, O. catharinense, and O. porosa (Lauraceae), Campomanesia xanthocarpa (Myrtaceae), and Mimosa scabrella and Parapiptadenia rigida (both Leguminosae).
This brief starts where responsible research should: with the source description of “Araucaria moist forests” as coniferous forest ecoregion of the Atlantic Forest Biome in South America. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as coniferous forest ecoregion of the Atlantic Forest Biome in South America. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Mar 31, 2026. The linked authority identifier is Q1429540. Authority coordinates are -26.360, -51.350. None of the 1 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
