In Clayton Village flows Rio Cardenas, a vulnerable stream protected by an urban forest. Many trees and palm species from the urban forest protect and offer shade to the stream.

Adiantum spp. ferns grow in the clay, while various moss species grow on wood. Water invertebrates and amphibious are not observable during the day. Small spiders hide between rocks. The air is charged with humidity and the temperature is high.

Underwater landscape

Fishes:

  • Neoheterandria tridentiger
  •  Poecilia gillii

Plants:

  • Adiantum spp.

The canal consists of red and brown clay. This stream is filled with rocks of differents shapes and sizes. Underwater vegetation is not present.

Threats to ecology

The river is contaminated with plastic and glass debris. Clothing and fabrics are also trapped in tree roots and palm branches.

Contaminants from urban wastewater and stormwater can change the color of the water, which varies from yellow to dark green.
