Daiyunshan (戴云山)
Daiyun Mountain National Nature Reserve (25°38′07″~25°43′40″N, 118°05′22″~110°20′15″E) is located in Dehua County, Fujian Province, China. The highest peak of the mountain has a maximum elevation of 1856 m. The total area of the reserve is 134.72 km2. The study site has a southern subtropical and mid-subtropical climate with an average annual temperature of 15.6–19.5◦C. The extreme minimum temperature is 16.8°C, and extreme maximum temperature is 36.6°C. The average annual precipitation is about 1700–2000 mm, along with average annual relative humidity of 80%.
Vegetation
The typical vegetation types are coniferous and evergreen broad-leaved forest. With the increase of elevation, the vertical band spectrum appears as follows: evergreen broad-leaved forest (650-1000 m), coniferous and broad-leaved mixed forest (1000-1200 m), temperate coniferous forest (1200-1650 m), mossy dwarf spring forest (1650-1765 m) and meadow (above 1750 m).
Flora
The vegetation arbor layer of the Daiyunshan Mountains is mainly composed of Pinus taiwanensis, Clethra cavaleriei, and Rhododendron farrerae, etc. The shrub layer mainly includes Eurya saxicola, E. rubiginosa and Ilex crenata, etc. The herbaceous layer mainly includes Diplopterygium glaucum, Woodwardia japonica, and Lophatherum gracile, etc. The P. taiwanensis is the most representative plant in Daiyun Mountain. The Daiyun Mountain has the best-preserved virgin P. taiwanensis forest community of more than 6 000 hm2 in mainland China, which mainly distributed at elevation of 1000-1800 m.
Fauna
Daiyun Mountain is an important biodiversity gene bank and a treasure house of rare wild animals in Fujian Province. It contains rare wild animals including: Muntiacus reevesi, Muntiacus vaginalis, Arctonyx collaris, Systematicus ellioti, Tragopan cabotiArctonyx collaris, Lophura nythemera, Callosciurus erythraeus, Mustela sibirica, Capricornis milneedwardsii, Panthera pardus, Neofelis nebulosa, Manis pentadactyla, Garrulax pectoralis, Arborophila gingica, *Bambusicola thoracica, etc.
Research sites of BEST network
In order to reduce the impact of human disturbance, the elevation gradients of Daiyun Mountain were set ranging from 900 m to 1600 m with the interval of 100 m. Eight permanent sample plots were set along elevation gradients in Daiyun Mountain. Each elevation set one a sample plot of 20 m ×30 m, and each plot was divided into three quadrat of 10 m ×20 m. The sample plots were selected from a representative forest community. Slope, aspect and other topographic factors of each plot were also measured by compass and iButton. All species with DBH above 1 cm in the plot were labeled and investigated, and species name, diameter and height were also recorded.
The top five important value tree species in each elevation ranging from 900m to 1600 m
