Vietnam Travel: Pu Luong Nature Reserve, Phu Luong Nature Reserve (a brand new adventure tour in Vietnam)

Pu Luong suggested nature reserve is situated in Quan Hoa and Ba Thuoc districts, in north-western Thanh Hoa province. Towards the north-east, the character reserve is bordered by Mai Chau, Tan Lac and Lac Boy districts, Hoa Binh province. The suggested nature reserve lies along two parallel mountain ridges, running from north-west to south-east, and therefore are bisected with a central valley. This valley contains several human settlements along with a large section of farming land, and, hence, isn’t incorporated inside the suggested nature reserve.

The 2 mountain ridges within the suggested nature reserve have starkly contrasting landforms, according to their different substrates. The smaller sized, south-western ridge consists of mostly igneous and metamorphic rocks, and includes rounded forested hillsides and wide, shallow valleys. The bigger, north-eastern ridge consists of heavily dissected limestone karst, and it is a continuation from the limestone range that runs from Cuc Phuong Park to Boy La province. Elevations within the suggested nature reserve vary from 60 to at least one,667 m.

The hydrology from the limestone ridge is complex, and there’s little if any permanent surface water. Around the south-western ridge, surface water is much more common and streams tend to be less periodic. However, the primary drainage options that come with the suggested nature reserve come in the central valley. This valley isn’t continuous but includes a saddle at its mid-point, which forms the watershed between two small rivers. One of these simple rivers flows north-west across the valley, and joins the Ma river, which runs towards the west and south from the suggested nature reserve. Another river flows south-east across the valley, and joins the Ma river further downstream.

Bio-diversity values

The main forest at Pu Luong nature reserve is classed as closed evergreen tropical periodic forest. Five major subtypes occur because of local variations in underlying substrate and elevation: lowland broadleaved forest on limestone (60 to 700 m) lowland broadleaved forest on schist/shale and clayey sandstone (60 to at least one,000 m) broadleaved submontane forest on limestone (700 to 950 m) coniferous submontane forest on limestone (700 to 850 m) and broadleaved submontane forest on basalt (1,000 to at least one,650 m). The character reserve will also support a variety of secondary plant life types, including secondary forests, bamboo, scrub and farming land.

The outcomes of latest botanical work on Pu Luong indicate the nature reserve supports an assorted flora, with a minimum of 1,109 vascular plant species documented to begin. From the conservation perspective, three primary forest subtypes found to begin might be considered really important. The very first, primary lowland forest on limestone and schist/shale, occurs close to the eastern border from the site, within the Co Bronchi. Primary forest in the region extends from 60 to at least one,000 m, and, in the cheapest elevations, supports high plant species diversity.

The 2nd significant primary forest subtype, primary coniferous submontane forest on limestone, is fixed to some couple of peaks inside the uplands from the Co Luong area and supports outstanding plant diversity, particularly regarding lithophytes and epiphytes. The globally threatened conifer Pinus kwangtungensis forms a conspicuous aspect of the flora in this particular forest subtype.

The 3rd significant primary forest subtype is primary submontane forest on basalt, which occurs around the upper slopes from the south-western mountain ridge inside the suggested nature reserve. The main forest on these upper slopes is characterised by high plant species diversity, including several across the country threatened conifers.

Regarding the vertebrate fauna of Pu Luong, as many as 84 mammal species (including 24 bat species), 162 bird species, 55 species of fish, 28 reptile species and 13 amphibian species happen to be recorded in the nature reserve up to now. Pu Luong nature reserve is a vital site for that conservation from the globally critically endangered, endemic primate, Delacour’s Leaf Monkey. The populace at Pu Luong continues to be believed to number 40 to 45 individuals, which makes it among the largest populations in Vietnam.
