Degraded areas are colonized by pioneer species, forming what is known as secondary vegetation.

Some of these pioneer species are:
- payagua naranja (Capparis speciosa)
- mistol de zorro (Castela coccinea)
- verde olivo (Cercidium praecox)
- yvyra rô (Pterogyne nitens)
- mbaracajá pyapê (Fagara pterota)
- aromita (Acacia caven)
- Prosopis ruscifolia
- Opuntia spp.
These communities are common in the Chaco, due to the conversion of natural areas to grasslands for livestock production.
In some areas natural grasses has been replaced by non-native species such as:
- Panicum maximum cv. gatton panic
- Cynodon nlemfuensis
- Digitaria decumbens
- Eragrostis curvula
- Brachiaria humidicol
