Since my last post about Ecosystem Service, I encouraged myself to create a new blog.  But I shared this blog with my students and colleagues.  The project itself was started in 2012 at the edge of Bukit Barisan Selatan National Park, in Lampung, Sumatera.  I am hoping that the new blog tells more about biodiversity provider of ecosystem service, which bird, which bat, and why there were around gardens and forest.  I picked durian as part of the title for a reason.  Durian is truly an Asian fruit.  Many Asians really…really like the fruit.  But do they know that birds during the day and bats during the night pollinate the flowers?  Some durians have white flower which one of the character preferred by bats.

We eat, we drink juice, etc., but sometimes we forget or don’t know how they originated.  Care to know more?  Well, just visit ‘Hey! They make my durians fruiting!’




Ecosystem service is at your garden

spiderhunterAt this age of climate change, incentives scheme to sustain the forest such as REDD+ and Payment for Ecosystem Service (PES) are quite a breakthrough. Everybody is talking about this, from one meeting to another, from one training to another.  But does the people really know about it? We got clean air and water…..What else? Well, look around at your garden.  Do you plant and get bananas? Does your plant keep flowering? Continue reading

A different citiwalk, a birdwalk

Birdwatching in a city is definitely unpopular, particularly when you talked about Jakarta, one of the most populated cities in the world. Once I uploaded my story of my recent birdwatching activity in the center of Jakarta, I received a suggestion to visit another birdwatching site up in the mountains. Sigh….

To most birdwatchers, seeing a rare, endemic species is maybe like winning a prestigious prize. But, this was not my intention that day. More than 10 years ago, our small bird club carried out a bird survey in the city. Our question was simple. Can we still see wild birds in Jakarta? Continue reading

Raffles, a naturalist in a colonial time

“It is impossible to convey the idea of the pleasure of sailing through this beautiful and unparalleled archipelago, in which every attraction of nature is combined”, Lady Sophia Raffles (during her field trip with Raffles in Bengkulu forest).

To most Indonesians, Sir Thomas Stamford Raffles was only a lieutenant general of Java during a short period of British colonization in Indonesia (1811-1814), and later was governor general of Bengkulu (1818-1824). Having been under ages of colonization under the Dutch, his appearance had at least made some significant changes to the welfare of the Indonesian people. He abolished the slave trade and changed the forced-agricultural system of the Dutch which forced farmers to grow particular plants (coffee, tobacco) without being paid into land-tenure system.  The other side of Raffles was less known but more exciting….

The three bulbuls

The fruits of Bridelia monoica

The fruits of Bridelia monoica

Bulbuls are birds of Old world tropics and are so attached with Indonesian folklore for long. An old Indonesian children song tells about the bulbuls singing all day from a Cempaka tree (Michelia champaca), quite accurate in portraying the behavior. Continue reading

Buitenzorg, ‘beyond cares’ of a ‘botanical island’

Buitenzorg was the previous name of the Bogor Botanical Garden, a plant conservation garden marked by the large buttresses of Canarium tree close to the gate. Established in 1817 by Prof. Dr. C. G. L. Reindwardt in collaboration with Kew Garden in England, this 87 hectares botanical garden becomes the leading natural plant preservation site in Indonesia and one of the most picnic destinations for many families. That was why I prefer to visit here during weekdays this summer.

Depok, the home of peri-urban butterflies

June is the perfect month of the year. The rainy season is over and spending some time in the morning outside is pretty much rewarding. Depok, my hometown, is in the outskirt of Jakarta, a transitional urban to rural area. Jakarta which just celebrated its 479th anniversary (on 22 June) has long history of development since the Dutch colonization. An 1811’s published book, “the Island of Java” by J.J. Stockdale explained the current situation of Jakarta (previously named Batavia) during those times. At present, the urban areas of Jakarta have been greatly expanded, making the original inhabitants of Batavia, the Betawi is following the movement of peri-urban areas, such as the growing town of Depok.
