Furry, shiny, scaly, fuzzy. Creatures of all kinds have returned to the recovering forest.
Visiting Instituto Terra you might hear what seems to be a dog barking in the trees. It is the call of a red-browed parrot (Amazona rhodocorytha). Along with other native birds, it has found a home in the recovering forest, one of 173 species of birds, 33 species of mammals, 15 species of amphibians, and 16 species of reptiles to return. A variety of creatures, large, small, furry, shiny, scaly, fuzzy, feathery, or slimy have come back. That includes lowland tapirs (Tapirus terrestris), valued due to their propensity to wander, defecating seeds as they go, spreading plant diversity. Smaller creatures like the Hay’s snouted treefrog (Scinax fuscovarius), a freshwater amphibian, venture out at night. The ocelots (Leopardus pardalis) are shy and rare. Some seem a little odd, like the collared lesser anteater (Tamandua tetradactyla), whose patterned coat gives it the appearance of wearing a fur onesie. For all native species, a regrown forest offers a chance to regain a lost habitat.
Once greenery was restored to the eroded areas, animals began returning. Each year, the habitat becomes more attractive to new, legitimate residents.
In particular, the return of one species has special meaning. The critically endangered jaguar (Panthera onca), the largest animal in this ecosystem’s food chain, has come back to the forest. It means that an alpha predator has sufficient prey, indicating that the balance of native species is working in harmony with nature. Another predator, the maned wolf (Chrysocyon brachyurus) has returned as well. Regenerating a portion of what was once a contiguous forest gives it more room to roam, increasing the chance for more breeding diversity. Its diet includes the nine-banded armadillo (Dasypus novemcinctus), also at home in the forest.
Among the more unusual forest dwellers, the crab-eating raccoon (Procyon cancrivorus) has made the reclaimed forest land its home, too. As the name suggests, it is fond of crabs found in inland rivers, and prefers to avoid humans. Thanks to reforestation around Instituto Terra, it can also indulge in its favorite pastime – climbing trees.
