Justification of Red List Category
Based on a model of future deforestation in the Amazon basin, it is suspected that the population of this species will decline by 25-30% over the next three generations, and it has therefore been uplisted to Near Threatened.
The global population size has not been quantified, but the species is described as apparently fairly common to common, at least in the centre of its range (del Hoyo et al. 2003).
This species is suspected to lose 18.7-19.8% of suitable habitat within its distribution over three generations (14 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). Given the susceptibility of the species to fragmentation and/or edge effects, it is therefore suspected to decline by a rate approaching 30% over three generations.
Dendroplex kienerii occurs along the Amazon River in inland South America, and is generally fairly common. It is distributed from extreme south-east Colombia and north-east Peru, through Brazil to the mouth of Rio Tapajós. Its range extends up the major Amazonian tributaries Solimões, Negro, Juruá, Purús and Madeira, but the species is generally rarer the further along these tributaries it is found, and reaches a southern limit in north-west Mato Grosso (del Hoyo et al. 2003). It is also thought likely to occur along the río Napo to Ecuador (Restall et al. 2006).
This species occurs below 200 m in the várzea (seasonally flooded forest) and igapó (permanently flooded forest) habitats of major Amazonian rivers. It is often associated with the successional environments of river islands (del Hoyo et al. 2003).
The primary threat to this species is accelerating deforestation in the Amazon basin (Soares-Filho et al. 2006, Bird et al. 2011). Although probably tolerant of disturbance to an extent because of its association with successional habitats, the extent of fragmentation projected is likely to cause significant declines (del Hoyo et al. 2003, A. Lees in litt. 2011). Proposed changes to the Brazilian Forest Code reduce the percentage of land a private landowner is legally required to maintain as forest (including, critically, a reduction in the width of forest buffers alongside perennial steams) and include an amnesty for landowners who deforested before July 2008 (who would subsequently be absolved of the need to reforest illegally cleared land) (Bird et al. 2011).
Conservation Actions Underway
None is known.
Conservation Actions Proposed
Expand the protected area network to effectively protect IBAs. Effectively resource and manage existing and new protected areas, utilising emerging opportunities to finance protected area management with the joint aims of reducing carbon emissions and maximizing biodiversity conservation. Conservation on private lands, through expanding market pressures for sound land management and preventing forest clearance on lands unsuitable for agriculture, is also essential (Soares-Filho et al. 2006). Campaign against proposed changes to the Brazilian Forest Code that would lead to a decrease in the width of the areas of riverine forest protected as Permanent Preservation Areas (APPs), which function as vital corridors in fragmented landscapes.
21-24 cm. Medium-sized, brown woodcreeper. Has a slim body with a relatively long tail, and a short, off-white bill, which is slightly decurved. The face is streaked whitish and blackish, with a notable white supercilium and brown iris. Otherwise reddish brown above and darker brown below.
