Assessment Notes

 

Taxonomic notes


Why suggested for a Global Red List Assessment?

This species is rare and occurs only in bamboos and is only known to the southernmost parts of the Atlantic Rainforest, a biodiversity hotspot from which around 12% of natural coverage still remains. It has only been collected in 2005 in a locality in Rio Grande do Sul, from which it was described, and in 2019 in the Santa Catarina State.


Geographic range

Atlantic Forest of Southern Brazil.


Population and Trends

The species is probably threatened by fragmentation and habitat loss of the Atlantic Forest, and the rare collections suggest it is a rare species.

Population Trend: Uncertain


Habitat and Ecology

Saprobic, growing only on bamboo. In Santa Catarina, found growing on Chusquea sp., in Rio Grande do Sul the bamboo species was not informed.

Subtropical/Tropical Moist Lowland ForestSubtropical/Tropical Moist Montane Forest

Threats

Almost half of the world’s bamboo species are in danger of extinction. Due to their flowering cycle, they are extremely vulnerable to climate change and habitat loss. Gloeoporus guerreroanus is found on bamboos in the Atlantic Forest, which is experiencing the greatest continuous deforestation event on Earth. Both known populations are in areas where agricultural and livestock farming (Cattle) are practiced. In Rio Grande do Sul, it was found close to extensive agricultural lands, and in Santa Catarina, it was found in a Conservation Unit- Parque Nacional de São Joaquim- where cattle from adjacent farms grase, being one of the main threats to the plants in the area. Recent political efforts also were conducted to reduce the area of the conservation unit, which could lead to an even greater loss of habitat to the species.

Conservation Actions

The main action to prevent the decline of the species is preservation of the known and eventual new discovered populations by implementing conservation areas.

Site/area protectionResource & habitat protection

Research needed

More surveys are needed to identify other populations. Also, studies on the habitat of the species and its relation with bamboo species.
