Nature of Gunung Gading

       Gunung Gading National Park has a very special star attraction - the Rafflesia, the world’s largest flower - and the park is one of the best places in Asia to view the Rafflesia’s spectacular blooms. Gunung Gading sprawls across four jungle-clad mountain peaks, and its dense primary rainforest is criss-crossed by crystal clear streams and waterfalls.here

Rafflesia

Gunung Gading was gazetted as a park in 1st August 1983 primarily to provide a conservation zone for the protection of the Rafflesia. It was opened to the public in 1994 and visitors can now view one of the most spectacular plants found on the planet. The park is easily accessible from Kuching on a day trip. Those wishing to stay longer can enjoy Gunung Gading’s other attractions - particularly its rainforest scenery, waterfalls and jungle trails. Some of these trails lead to the peaks of the mountains that make up the park and offer challenging jungle treks.

#RAFFLESIA

The Rafflesia, the world’s largest flower, is a parasitic plant found only in Southeast Asia, and then only in sub-montane hilly forests at elevations between 400-1,300 metres. Sir Stamford Raffles and Dr Joseph Arnold were the first Europeans to discover the Rafflesia. In 1818, whilst on a field trip near the town of Bencoolen (Bengkulu) in Sumatra, they came across a huge specimen that measured 97 cm in diameter. This species was later named the Rafflesia Arnoldi. When news of the discovery reached the botanical community in 1820 it caused quite a sensation with murmurings of disbelief.

 

There are thought to be 17 species of Rafflesia, some of which may already be extinct. Three species are found in Sarawak - the Rafflesia Pricei, Rafflesia Arnoldi and Rafflesia Tuan-Mudae, which is actually a type of Arnoldi. Only one species, R. Tuan-Mudae, is found at Gunung Gading.

The Rafflesia is as unusual as it is spectacular. Much of the flower’s biology remains a mystery to this day. It has no specific flowering season and it has no roots, leaves or stem. The Rafflesia depends on a host vine - the tetrastigma, a member of the grape family. Scientists are still unsure why the Rafflesia associates itself with the tetrastigma vine or how the seeds of a Rafflesia germinate and grow. What is known is that threads of tissue spread out within the vine and absorb nutrients. After 18 months a small dark brown bud appears.

Such a long period of growth means that there is a high risk of damage; even when a bud forms there is no guarantee that it will mature into a Rafflesia flower. A bud takes nine months to mature, when it may measure up to 16 cm in diameter, and studies have shown that a high percentage of buds do not survive, as they are susceptible to both drought and heavy rain.

After nine months the brown ‘leaves’ of the cabbage-like bud open, revealing the underside of the petal-like lobes. It takes several hours for a flower to open fully. There are usually five thick and fleshy red-coloured petals, covered in lighter coloured spots, warts and blotches. The Rafflesia only blooms for 3-5 days, before it starts to blacken and rot. Although it is quite common for a number of buds to occur in a cluster at the same site, it is rare for two plants of the same cluster to bloom at the same time.

Rafflesia flowers are either male or female, and therefore cannot self-pollinate. For pollination to take place, a male and a female flower must bloom at the same time and pollen must be transported over considerable distances. In the Rafflesia’s case pollination is carried out by carrion flies, so whilst in full bloom the Rafflesia gives off a foul smell of decaying flesh to attract them. Seeds are thought to be dispersed by rodents and other small mammals which eat the flowers. Scientists remain baffled, however, as to how the tiny seeds infest the roots and stems of the host vine.

Loss of habitat is the greatest threat to the survival of the Rafflesia. Its reliance on the tetrastigma vine does not help matters. With other endangered species it is possible to implement a range of conservation measures such as trans-location and the establishment of nurseries. However, these measures are not possible with the Rafflesia due to its very high degree of specialisation. The establishment of totally protected conservation zones is the only way to preserve this unique plant.  Gunung Gading National Park in Southwest Sarawak is such a conservation zone. Gazetted in 1983, the park covers an area of 4,106 hectares and forms a safe and secure habitat for the protection of the Rafflesia.

#WILDLIFE

Gunung Gading is home to a range of animals including civet cats, wild boar, small deer, porcupines, monkeys and giant squirrels. However, as the Park is surrounded by villages, most of the wildlife stays deep in the jungle, on the upper slopes of the park’s mountains, and therefore Gunung Gading is not an easy place for spotting wild animals. Visitors who opt for a summit trek are more likely to see some of the park’s wildlife. 

#WATERFALL

This is the easiest and shortest trail in the park. The trail follows a river and passes seven waterfalls, although not all of the waterfalls are accessible. Waterfalls 1, 3 and 7 are signposted. If you need to break the trek up, waterfall 3 provides a pleasant resting spot. It is only a 10 metre detour from the main trail. The whole trail passes through some great jungle scenery before reaching the final waterfall, and a perfect dip pool surrounded by forest.

#BATU BERKUBU

Batu Berkubu, on the slopes of Gunung Sebuloh, served as communist base camp during the insurgency. Although it is often called a cave it is in fact a huge rock which along with the surrounding trees provides a cave-like sheltering area. The trek from the Summit of Gunung Gading to Batu Berkubu is relatively easy, taking about 2 hours to cross a valley.

#GUNUNG GADING SUMMIT TRAIL

First follow the red and white Waterfall Trail until you reach the junction for the seventh waterfall. The trail’s marking then changes to yellow and red. This is the start of Gunung Gading Summit Trail. From the junction it takes another two and a half hours to reach the summit, which was the location of a British army camp during the communist insurgency of the 1960’s. The remnants of the camp - a helicopter pad, water tank and barbed wire fencing - still remain to this day, and appear somewhat out of place in the middle of a national park. However, they are of historical significance and the park staff intend to preserve the summit area as it has been for the last 30 years.
