I took this picture at the ruins of Ta Prohm, one of the temples of Ankor Wat. This temple has not been restored - when the complex was 'rediscovered' it all looked like this. The light conditions were pretty poor.

Biological weathering is a form of weathering caused by the activities of living organisms for example, the growth of roots or the burrowing of animals. Tree roots are probably the most significant agents of biological weathering as they are capable of prising apart rocks by growing into cracks and joints. Plants also give off organic acids that help to break down rocks chemically.

Strangler figs are tall canopy trees which can grow to 148 feet in height. The manner in which they reach the canopy is a strange story. The forest floor of a rainforest is a difficult place for seedlings to grow. There is little light and a lot of competition for water and nutrients. Strangler figs have made an adaptation to avoid these difficulties. Unlike most plants, strangler figs start out their lives as epiphytes in the crook of a tree or on its branches. Tiny, sticky seeds are deposited high in a tree by animal droppings. The seeds are not affected by the animal's digestive tract and soon germinate.

The strangler fig has an aggressive growth habit that insures its survival in the rainforest. The seedlings grows slowly at first, getting their nutrients from the sun, rain and leaf litter that has collected on the host. The stranglers send out many thin roots that snake down the trunk of the host tree or dangle as aerial roots from its branches. When the roots reach the ground they dig in and put on a growth spurt, competing with the host tree for water and nutrients. They also send out a network of roots that encircle the host tree and fuse together. As the roots grow thicker they squeeze the trunk of its host and cut off its flow of nutrients.

In the canopy the strangler fig puts out lots of leaves that soon grow thicker than the host tree and rob it of sun light. Eventually the host dies from strangulation, insufficient sunlight and root competition, and the strangler fig stands on its own. A hollow center is all that remains of the host.

Some figs grow root systems that develop into thin buttresses that can spread out to a distance of about 30 feet. Other figs grow aerial roots from their branches that, when they reach the ground, root themselves and become another trunk on the same tree. Strangler figs have light colored bark and umbrella shaped canopies. Green above and lighter below, the leaves are simple, ovoid and usually between 1.5 - 3 inches long. Waxy leaves protect the strangler fig from drying winds and sunlight that it is exposed to high in the canopy.

Hi James,

this is amazing. Are you sure it's not off some fantasy set like 'Lord of the Rings,' the home of some madrigal!

It's surreal.

Great capture.

Hello James,
Even though this is a scanned shot, it clearly and artistically shows the forces of nature if left to work unhindered.
Not only is the temple ruin being discoloured and eroded by algae, mosses and lichens, but blatantly by a huge fig looking like a sci-fi octupus taking command.
I fine contribution to TN!
TFS and best wishes, Ivan

Hi James

Fascinating shot here, the scale of the Strangler Fig is very impressive, and what a way to show it! Great composition and colours, thanks for sharing!

Paul

wonderful sobject and very good photo

ciao

These roots of a Strangler Fig tree look like the tentacles of a giant octopus, gripping one of the stone temples at Ankor Wat, James.
In this picture, they also look like an avant garde creation in sculpture with abstract motifs.
We have a variant of this tree in India which is worshipped by Hindus as the incarnation of God Vishnu. It is called Vat-vriksha, Bodhi-vriksha or Bargad in common language.
The picture gives a perfect impression on this ancient ruin. I have a deep desire to visit this region when I return home after retirement.
Thanks and regards.

Hi James,
Great story and photograph of the strangler fig. They are not so nice to the ruins either, as in this case in Angkor Wat. Excellent job. Regards,
Hakan

Hi James,
What a cool shot of Ta Prohm, looks as though it were a scene from 'The Jungle Book'. Great shot showing the natural deteriation of a man made structure. I did not know plants could create chemicals that break down rocks. Thanks for the great note. :)

Hello James!
I do not know why I overlooked this picture before! Fantastic POV and amazing place! These trees really look great!
Bravo for the note too.
Best withes,
Radomir

Wonderful photo

Hi James
An unreal image...
It seems to me like and alien came from outer space and dissolving the earth houses... :)
It an exaggerating vision, but certainly it's a demonstration of the nature power...
great picture and image...

Ciao James.
What a fantastic scene! When nature is strenger than human law.
Congratulation.
Marco

Wow, thank you having the right "eye" to get this one!CarOze

Hello James,
Even I agree with Ram Thakur that it looks like the tentacles of the giant octopus holding the temple. Unique composition with mystique effects. TFS
