Pinus densata (Sikang Pine) is a species of pine tree native to the eastern Himalayas and adjacent areas in China, Bhutan, and Nepal. It is named after the region of Sikang (now part of Sichuan province) in China where it was first discovered.
Size and Growth Habit: Sikang Pine is a medium-sized evergreen tree that typically reaches heights of 20-30 meters (65-98 feet). It has a straight trunk with a conical to rounded crown. The branches are often densely arranged and slightly ascending.
Needles: The needles of Pinus densata are arranged in bundles of five and measure approximately 7-12 cm (2.8-4.7 inches) in length. They are usually dark green and slightly twisted. The needles persist on the tree for several years before shedding.
Cones: The cones of Sikang Pine are ovoid or egg-shaped and grow to a size of about 6-10 cm (2.4-3.9 inches) in length. They have thick scales with a woody texture. The cones are initially green and turn brown as they mature. They typically persist on the tree for several years.
Habitat: Sikang Pine is adapted to mountainous regions and grows at high elevations between 2,500 and 4,500 meters (8,200-14,800 feet) above sea level. It occurs in a variety of habitats, including mixed coniferous forests and subalpine zones. The tree is well-suited to cold climates and can tolerate frost and snow.
Ecological Importance: Pinus densata plays a vital role in the ecosystems of the eastern Himalayas. It provides habitat and food sources for various wildlife species, including birds, mammals, and insects. The tree also helps stabilize soil, prevent erosion, and contribute to the overall biodiversity of the region.
Conservation Status: The conservation status of Sikang Pine is not well-documented. However, like many tree species in the Himalayan region, it may face threats from deforestation, habitat fragmentation, and climate change. Conservation efforts are necessary to protect and sustain the populations of Pinus densata.
