Priority places: Northern Annamites

Significant as primate habitat

The Greater Annamites ecoregion is subdivided into three sub-ecoregions, each of which comprises a number of Priority Landscapes. These are the North (this page), Central and Southern Annamites.

Some landscapes were identified as potentially globally significant, but they could not be classified due to a lack of data and information. These are grouped under Survey Areas.

Northern Annamite

Priority Landscape NA4 | Ranking: CRITICAL

This Priority Landscape comprises all the main landscape elements that best represent the northern sub-division of the Greater Annamites. This area comprises some of the most extensive remaining areas of evergreen forest in the Forests of the Lower Mekong Ecoregion Complex. The scale and integrity of the forested landscapes make this the optimum area in the Greater Annamites to support populations of the large mammal endemics such as Saola and Muntjacs.

Northern Indochina Limestone

Priority Landscape NA1 | Ranking: ACUTE

Situated in the most northerly part of the Greater Annamites, this landscape is not heavily represented in the ecoregion/sub-region, but is found in fragmented areas throughout the Northern Highlands and in southern China. The area is important for several limestone specific taxa, and is vital for the conservation of primate species–particularly the Delacour's Langur, which is only known from this landscape.

Central Indochina Limestone

Priority Landscape NA6 | Ranking: CRITICAL

This area plays host to numerous limestone specific taxa, including a number of Annamite endemics–more so than the Northern Indochina Limestone (NA1), making the Central Indochina Limestone the most extensive limestone area and holding the most distinctive limestone community in the Greater Annamites. This area is critical for the conservation of primate species, and limestone specialist species such as the sooty babbler.

Upper Chu River Watershed

Priority Landscape NA2 | ranking: HIGH

This Priority Landscape is made up of two distinct elements, which could be managed as a single unit. The area surrounding the proposed Nature Reserves of Pu Hoat and Xuan Lien is the only surveyed part of the Transition Zone and early indications are that it is of botanical importance. Faunal surveys have been far from complete but the indications at present are that some typical Annamite species are missing. However, in Pu Huong Nature Reserve there is evidence to suggest that this area may once have supported Saola (and may still) and therefore is likely to be of conservation importance. The significance of this area, therefore, rests on its representation of transitional habitats between the Annamites and the Northern Highlands.

Ben En Lowlands

Priority Landscape NA3 | ranking: HIGH

Surrounding Ben En National Park is an area of coastal lowland evergreen forest. The importance of this lowland coastal forest in comparison to the lowland forest at the base of the eastern Annamite flanks is yet to be fully understood. These forests support at least two butterfly species currently unrecorded elsewhere. Unfortunately, these forests are also highly degraded, but they retain conservation importance as the last remaining substantial block of this habitat.

Ke Go and Khe Net Lowlands

Priority Landscape NA5 | ranking: CRITICAL

Ke Go is one of the last substantial areas of lowland forest on the immediate eastern side of the Greater Annamites. The area is of outstanding significance for Lophura pheasants, and may be the only location where viable populations persist. Due to its accessibility, the area has undergone substantial degradation and is, therefore, of particular short-term conservation priority.
