Time for another episode of cool things happening in the world of environmental research. Today, we have a project that is helping us better understand the forests. The tool being used for this project? Lasers!

Researchers from the University of Gottingen have been looking into the many different kinds of structures that exist in forests around the world. Using 3D laser scanners, they went all over the globe, recording 3D models of the forests they visited over the span of two years. One of the things they specifically focused on was primeval forests; those that haven\\u2019t had their development affected by humans. Believe it or not that is still about 30% of the world\\u2019s forests. One of the things these researchers hope to accomplish by doing this is to better understand how humans affect forest development by comparing and contrasting the different structures to be found in ancient forests and those that have been altered by human activity.

This looks to be very good research. For maybe the first time, scientists are doing a study into how humans affect forest development using an actual control group. Before, we had really only been comparing past information on a given forest with what is happening now. There is nothing wrong with that and it can still be very useful, but it can be very difficult to say with certainty how things might have been different. Now, with these 3D models that have been created, being used in conjunction with satellite data, researchers can find two areas of a similar forest structure and climate, one that has been affected by people and one that has not. Then they can be tracked over a period of time to observe how their development diverges. For perhaps the first time ever, they will be able to track two similar forest structures over a period of time, providing us with excellent information on the environment and our impact on it.\\xa0

Is that really possible? Isn\\u2019t most of the primeval forest actually rainforest in the south of the world and the human influenced stuff the boreal forests in the north? Not as much as you would think. There is plenty of rainforest in Brazil that has been affected by commercial development and there are other rainforests in North America in the states of Washington and Alaska that a person could wander in for days and not find a trace of humanity. There is plenty of boreal forest in North America and Northern Asia that is also untouched by humans. People don\\u2019t realize how many millions of acres are actually protected from any kind of development.\\xa0

There are of course different levels of development as well. Some areas of forest are surrounded by heavy human development, some have small towns scattered within them. Others have been logged and replanted while others are crisscrossed with trails for various off-road vehicles. Some of these forests have been developed in some way for decades, others for just a few years.\\xa0

This new study is valuable precisely because using the researchers\\u2019 methods, it will be possible to track these various stages and types of development to actually see what the long term effects are. The results will be a huge help to understanding human impact on the environment and helping us learn the best ways to minimize it while still making it possible for people to have homes to live in as well get out and enjoy some of that nature we are talking about.\\xa0

TARTLE would also like to commend the researchers on their use of our basic philosophy. They didn\\u2019t just rely on satellites and or reports from others. Instead, they did the hard work of going to the source and getting the primary data they needed to get the best possible results.\\xa0
