The Poodří PLA stretches along the course of the Oder River and includes the central part of the northeastern half of the Moravian Gate.

Endangered species like the water violet and floating fern the yellow water-lily bloom near the blind river branches.

Forests cover about 10% of the Poodří PLA area and consist mainly of trees such as common hornbeam, pedunculate oak, small-leaved lime, and ash.

In the herbaceous layer of the forests, flowers such as snowdrop, wood anemone, early purple orchid, and bear garlic can be found.

Some of the wood-decaying species include the hen of the woods (Grifola frondosa), umbellate polypore (Polyporus umbellatus), cauliflower fungus (Sparassis nemecii), Hartig's fire fungus (Phellinus hartigii), oak bracket (Inonotus dryadeus), dryad's saddle (Inonotus dryophilus), resinous polypore (Ganoderma resinaceum), glossy polypore (Ganoderma lucidum), ash tree bracket (Perenniporia fraxinea), coral tooth fungus (Hericium coralloides), lion's mane mushroom (Hericium erinaceus), bearded tooth fungus (Hericium flagellum), and orange-toothed crust (Sarcodontia crocea).

The insect fauna is rich, with many local species, such as the marsh fritillary butterfly, black hairstreak, stag beetle, brown chafer, and bush-cricket Stetophyma grossum.

Endangered fish species in the Oder River include the spined loach, bitterling, and brook lamprey, while the striped rudd can be found in the pools.

The Poodří PLA is home to many amphibian species, with the great crested newt, fire-bellied toad, and European tree frog being among the most significant in terms of nature conservation.
