May 20

It seems to me that there are many topics I want to post in the blog during this time. Is it the result of my wondering mind, for which too much free time is provided? Anyway, before I put the pie of other idea in my blog, I would like to tell all you guys about the news in my hometown, Thailand.

If you still remember, I once mension about the Kho Yai, the biggest Thailand's national park. Now, there are several roads cutted cross trough this forest and the government want to enlarged it to meet the increasing need of the transport connection.

Concerining with the wildlife protection (or with another propose, I can't say) the official agree was occured yesterday (18 May 2006) between the Highways Dep. and The national park. They proposed the construction plan of the "Animal-Bridge", an evelated crossing, over the highways. It will link together 2 Thai's national park, Kho Yai and Tap Larn in order to save the innocent life such as tigers, which often killed by car crash.

Lovely! Now you guys have some backgroud knowledge to discuss with me.

From my ecology class, instructor told me about the efficient designs of conservation area. One of these suggest us to consider on "corridor" and "steping stone"; In the term of theory, it makes possible for the creatures to roam from one side to another. This mean, for them, a wider niche.

Firstly, I agreed with it right away. But my teacher said "It's not that easy" Why?

Usually animals use the same ways in one period of time to go to the specific places, or for the specific reasons. To give some example, I'm not sure that we have a trustworthly evidence about the specific time of the animals' migration between these 2 sites; or the number of animal, kind of them, specific locations and so on. It's not too unrealistic to say that scientists are challenged by this obstacle, since our knowledge dealing with wildlife conservation is still thounsands of mile from "Zeta". I don't mean that we have to know every step of them to make a perfect bridge project. However, many researches have to be done in order to support the design; location, number, size, material, etc, before the scientists and those officers make a dicision wisely.

In my humble view, I hope the government will do a lot of "homework" before launching the sutiable project that benefit both us and our friends at Kho Yai and Tap Larn. No doubt, it cannot be anyothers except the scientists whom are goning to be challenged. Good luck for them!

Dear Note,

Quite an interesting topic, you have risen. I just checked this website (http://en.wikipedia.org/wiki/Wildlife_corridor) and I found that the pros of corridors is that it creates a wider niche, as you have mentioned. The additional cons, further from your mentioned lack of data, is the possibility of the "edge effect" and a more-or-less disruption of the ecosystem.

The "edge effect" mentioned here is that once the niche is changed, certain species (especially opportunistic ones such as the Cowbird or other opportunistic species) may outgrow the former fauna (such as songbirds). Cuz the corridor's main purpose is for the tigers, but will it be only the tigers who will move through the corridor?

Anyways, time to comment my blog, man!
