Source-derived summary

Serra das Almas Private Natural Heritage Reserve (Portuguese: RPPN Reserva Natural Serra das Almas) is a private natural heritage reserve in the states of Ceará and Piauí, Brazil.

Origins

The reserve has its origins in a trip made by Herbert Fisk Johnson Jr. of S. C. Johnson & Son in September 1935.

He flew from Milwaukee, Wisconsin, to Fortaleza, Ceará, in an amphibious twin-engine Sikorsky S-38.

His aim was to learn more about the carnauba palm tree (Copernicia prunifera) of north eastern Brazil which produced wax, one of the main products of his company, and to determine whether groves of these trees could produce enough to meet future demand.

By 1937 the company had a carnauba processing factory in Fortaleza, and in 1938 had a research farm, later donated to the school of agronomy of the University of Ceara.

In 1960 the company created a Brazilian subsidiary in 1960, and in 1990 launched the environmental project that led to creation of the Serra das Almas Natural Reserve.

Location

The reserve was created on 8 September 2000 with an area of 4,749.58 hectares (11,736.5 acres) of the municipality of Crateús in the state of Ceará.

Almost half of the reserve's original Caatinga vegetation had been devastated.

It is the property of the Caatinga Association (Associação Caatinga).

Editorial analysis

Critical limits

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.
