Justification This species has a moderately small population, and although it may persist in small forest fragments, it is likely to be declining. It is consequently listed as Near Threatened.

Range & population Clibanornis dendrocolaptoides was considered very local and scarce throughout its range in south Brazil, south-east Paraguay and north-east Argentina. It was almost certainly previously overlooked, and there has been an increase in records now that its voice is known, and as a result its population is now believed to exceed 10,000 mature individuals.

Ecology: This species occurs in various forest habitats up to 800 m. Dense bamboo and other vegetation over water is considered by some to be optimal habitat¹⁰, but it appears not to be restricted to large-leaved bamboo, and the bamboo relationship may be coincidental.

Threats It is presumably threatened by the rapid destruction and fragmentation of Atlantic forest. However, it is reported to persist in small forest fragments¹¹, which suggests that it is unlikely to be undergoing a rapid population decline. Depending on its ecological requirements, the cutting of bamboo thickets could have a serious effect. In Argentina, the building of dams has flooded parts of its former range.

Conservation measures underway It occurs in Caaguazú National Park and Ypetí Private Nature Reserve (Paraguay)², Iguazú National Park, San Antonio Strict Nature Reserve, Urugua-í Provincial Park (Argentina)⁵ and Iguaçu National Park (Brazil). It may also occur in São Joaquim National Park, Santa Catarina.

Conservation measures proposed Conduct ecological studies to determine this species's precise habitat requirements, as well as its tolerance of secondary and fragmented habitats. Survey areas of suitable habitat within and surrounding the known range in order to determine true distribution and abundance. Protect suitable habitat around Urubici to prevent further habitat degradation⁷.
