|Iron-laced cliffs at Bako National Park|
Last week we had a chance to re-visit Bako National Park, a wonderful slice of Sarawakian terrain, flora, and fauna. It has a little bit of everything – mangrove swamp, mixed dipterocarp forest, high, dry kerangas (rocky highlands with almost no soil, but rich with Nepenthes), all packed into a peninsula that juts out into the South China Sea. We visited there for a couple of days in 2008, and we were so enchanted that we were anxious to go back!
Bako is about 30 kms from Kuching but seems so much further away. After a bus ride to the village of Bako you board a boat and take a 30 minute thrill-ride to get to the park. It doesn’t have to be a thrill-ride, but when the sea is a little choppy and they talk about aggressive Sarawakian crocodiles on the shore, that is thrilling enough!
The Park headquarters is just off the beach, and is besieged by the three types of monkeys that live in Bako – the mischievous macaques, the luxurious Silver-Leaf Monkeys, and the famous Proboscis Monkeys. Macaques can get into almost anything with zippers, doors, or handles -- and they do! The "Naughty Monkey" sign is very useful!
The first big hike we took was to the top of the keranga on the Lintang Trail. We started out on a boardwalk through a lowland swamp dominated by palms, and then made our way up to the top of the plateau.

|Drosera spatulata -- the hungry Sundew!|
The keranga at Bako and certain acidic sandy outcrop areas in South Carolina share something in common – the plant Drosera (Sundew) that preys on the tiniest of insects, with its glistening sticky hair-like glands. This treacherous little ruby is often overlooked in favor of the other carnivores nearby.
The Asian Pitcher Plant– Nepenthes spp. are vining beauties that come in all different shapes and sizes. This vine generally starts with its larger pitchers close to the ground, & decreases the size of its bug-catching vessels by the time it is hanging from trees and shrubs. Nepenthes lure unsuspecting insects into their fluid filled pitchers, which are actually modified extended mid-vein tendrils of the leaves [woah!]. Then, the insects can’t get out, and end up as plant food. Our own, non-vining Pitcher Plants in SC, the (unrelated) Sarracenia, have the same strategy, but in a cone-shaped modified leaf blade. We had a lot of fun looking at the different kinds and morbidly peeking into their pitchers for victims. (plants gotta eat too! …..)

On the kerangas there are also examples of epiphytic “Ant Plants.” These provide shelter for ants, which, in turn, protect the plants from herbivores (and intrusive botanists)!
|Who lives here? Ants!|
There are several kinds of ant plants but this one, Hydnophytum sp., has a calloused bulb-like base – think of a yam made out of mud, stuck on the side of a tree – with several small branches protruding.
|Sea Coconut -- Nypa fruticans|
Once we finally got down from the keranga, we wandered the mangrove forests along the beach. Washed up on the sand we found Sea Coconut, the edible fruit of the Nipa Palm (Nypa fruticans), that grows up and down the rivers and streams along the Borneo coasts.
But we found another surprise in a narrow strip of vegetation just off the beach. A Tacca! Sometimes called Polynesian Arrowroot or “the Bat Flower,” Tacca leontopetaloides is an herb whose leaves look very much like Amorphophallus (Corpse Flower) leaves, but the cluster of flowers is very different.

|Bearded Pigs on the Mangrove beach|
We weren’t the only beach combers at Bako that day. The park is roamed by several families of wild boars, the famous bearded pigs. They are equally at home plowing up the beach with their snouts, or creating wallows (which fill with rain and eventually become frog habitat!) in the jungle interior.
|Male Proboscis Monkey|
Everyone comes to Bako hoping to see the famous Proboscis Monkeys, an endangered and protected species found in Borneo only in a few enclaves in Sarawak and Sabah. You’ll recall that we missed them when we were in Maludam National Park. But this time we were so fortunate!
|Female Proboscis Monkey|
Several small groups of Proboscis Monkeys made their way along the tree-like Pandan plants lining the beach, right in front of the park headquarters. Each morning and evening, they feed on the tender bases of Pandanus shoots. The males, especially, have rather large pot-bellies and, of course, they have that distinctive nose! They were posing in the trees, eating Pandan and even swinging from branch to branch.

Next time we head to a different Malaysian state in Borneo – Sabah, at the North-eastern end of the island. We’ll be deep in the rainforest at the Imbak Canyon Conservation Area, talking to the staff there about field collection technique and creating an herbarium. Hope you’ll be joining us!
