Copies of all 611 plant species already cataloged by scientists in the region that goes from the beach Itaguaré to the Serra do Mar are deposited in the Herbarium of Universidade Santa Cecilia, the only one of Santos.
Created in 1998 under the stewardship biologist Zélia Rodrigues de Mello, he now has 6000 specimens, part of the Brazilian Network of Herbaria, Botanical Society of Brazil.
There, the plant samples are dried under pressure between sheets of absorbent paper on wooden planks, technically known as presses.
Held in conditions of constant temperature and humidity, free from insect attack, may be preserved indefinitely.
After drying, the plants are displayed on cards and given a label, where are recorded all information concerning the place where they were collected, and aspects that can not be recovered through the sample, as their odor and color of flowers and fruits, which are change with drying.
Highlights of the collection are the flora of the sandbank Bertioga algae from the coast of Santos, flora of the Botanical Gardens in Santos, native and exotic medicinal plants used by the population of Santos.
Area is endemic animals
Studies conducted over the past years Itaguaré indicate the presence of many endemic species of animals, or that do not exist elsewhere. This applies, for example, 13 species of anurans (frogs, toads and frogs), identified by scientists at USP.
The area is also habitat for about 230 bird species, many waterfowl, which nest along the 12.5 km long river Itaguaré.
Among the birds, especially Tucano-de-Bico-Black (Ramphastos vitellinus), a species regarded as probably extinct in the State of Sao Paulo, the Red List of the State Secretariat of Environment. There is also record the presence of alligators-the-crop-yellow, Ocelot, pumas and jaguars among other mammals.
