How trees can help in finding human body in forests – BGR

  • Researchers have developed a way of using cue from plant life to detect human bodies in wild areas.
  • Foot patrols and rescue teams often struggle to find carcasses in dense forests, but the plant can react strongly to humans’ presence of decay and offer alert teams to warn that something has been buried or rot nearby. Used to be.
  • In the future, plants can be an important tool in finding missing people in forest areas.

A surprising number of humans die in wooded areas. Whether it was from a tragic accident to their bodies, there was an attempt by one person to hide the remains, search parties can find it difficult to find human remains in a really dense forest, even canons. Even with the help of.

Now, a new study published Trends in plant science Provides the possibility that plants may be a major ally in the quest to decompose the body. The idea that along with the human body breaking down, it can dramatically change the soil structure and thereby affect any plant that grows nearby. Those plans can then act as a beacon, alerting search teams to areas of interest.

Research, led by a team at the University of Tennessee, points to a change in plant behavior in the presence of decaying corpses. They call the immediate area around a body a “cadaver decomposition island”, as it differs from the rest of the soil in the forest in a significant way.

“When people go missing and die – whether from natural causes or play foul – their bodies begin to disintegrate when the weather warms,” ​​research co-author Neil Stewart writes chit chat. “And if they disintegrate in the forest under the shadow, it can be difficult, if not impossible, to find and fix their dead bodies.” One solution is to learn how plants respond to humans disintegrating and then they hear what they are telling us about people who have died under canopies. ”

One of the largest contributions of dead bodies to the soil on which it rests is a large flow of nitrogen. Plants love nitrogen, which accelerates growth and leaves the leaves of surrounding plants greener than normal. As Stewart points out, other changes can occur depending on the drugs a person was doing in the form of metals or metals found in his body.

Researchers still have a long way to go as their structures can be put into practice to take cues from plant life, but their early work is promising. Some obstacles to be addressed include how to distinguish plant life changes from a dead human versus similar-sized animal, such as a large deer. Going forward, the team hopes to better understand what “trees and shrubs have to tell us about missing people.”
