Top 5 Reasons why you should plant trees

According to Modern Diplomacy, here are the reasons why you should plant trees:

  • Trees fight climate change

Wish you could do more than recycling and reducing your carbon footprint to combat climate change? Trees have you covered. Through photosynthesis, trees absorb harmful carbon dioxide, removing and storing the carbon and releasing oxygen back into the air.

  • Trees clean the air and help you breathe

Trees don’t just absorb CO2. They also absorb odors and pollutants like nitrogen oxides, ammonia, sulfur dioxide and ozone. It’s estimated that one tree can absorb nearly 10 pounds of polluted air each year and release 260 pounds of oxygen.

  • Trees prevent soil erosion and rainwater runoff

During heavy rains, water runoff finds its way to streams, lakes, and wetlands, creating the potential for flooding. It also picks up and carries pollutants along the way. The EPA and the Center for Watershed Protection are recognizing the importance of trees in managing runoff. Leaf canopies help buffer the falling rain and their roots hold the soil in place, encouraging the water to seep into the ground rather than run off.

  • Planting trees are easy

Gardening can be intimidating for newbies because there are so many variables. Which plants and flowers should you put next to each other and which should you separate? Which bloom in the summer and which bloom in the fall? When you’re dealing with trees, there’s none of that. Just choose a spot in your yard and you’re good to go. Here’s a video showing you all you need to know about planting your young trees:

  • You’ll save money

Trees conserve energy in summer and winter, providing shade from the hot summer sun and shelter from cold winter winds. With trees standing between you and the elements, you’ll spend less on your energy bill to heat and cool your home, where to buy liquor.

Biodiversity in trees

According to Science News, for a decade, researchers explore how tree species diversity affects the coexistence of trees and their growth performance in the largest biodiversity experiment with trees worldwide, the so-called ‘BEF-China’ experiment. One of the main interests of the BEF-China team is to explore the relationship between tree diversity and multiple ecosystem functions, specifically those benefiting society, such as wood production or the mitigation of soil erosion.

For this purpose, an experimental site of c. 50 hectare in subtropical China was planted with more than 400,000 trees and shrubs. The findings now shed new light on tree-tree interactions: The local environment of a tree strongly determine its productivity, meaning that tree individuals growing in a species-rich neighborhood produce more wood than those surrounded by neighbors of the same species. “Particularly impressive is the finding that the interrelations of a tree with its immediate neighbors induce higher productivity of the entire tree community (i.e. the forest stand) and that such local neighborhood interactions explain more than 50% of the total forest stand productivity,” says forest ecologist Dr. Andreas Fichtner.

The scientists were also able to identify mechanisms explaining why species-rich neighborhoods promote tree productivity. Their findings show that competition is less prevalent in species-rich neighborhoods and that species-rich neighborhoods can even lead to facilitation by e.g. an improvement of the microclimatic conditions or by positive interactions with soil fungi, where to buy liquor.

“These findings contribute to a deeper understanding of tree interactions and the functioning of forest ecosystems, and are particularly relevant for nature conservation and forestry,” says Prof. Dr. Goddert von Oheimb from the Department of Forest Sciences at the TU Dresden. This, in turn, will benefit the multifunctionality of forest ecosystems and their associated ecosystem services benefitting the society. “This shows that biodiversity conservation is not exclusively an ecological or ethical issue, but rather a necessity ensuring the socio-economic welfare,” says Dr. Andreas Fichtner.

Water insufficiency stresses urban trees

According to Eurek Alert, a research that was revealed on March 13 says urban trees are able to survive heat and insect pests well unless they’re thirsty. The lack of water does not only harm trees but also allows other outsized effects to occur.

“We would see some vibrant urban trees covered in scale insects, but we’d also see other clearly stressed and struggling urban trees covered in scale insects. We wanted to know what allowed some trees to deal with these pests so much more successfully,” says Emily Meineke, a postdoctoral researcher at Harvard and first author of a paper on the study.

“This is important because trees need to grow in order to perform valuable ecosystem services, such as removing pollutants from the air and storing carbon,” says Steve Frank, an associate professor of entomology at North Carolina State University and co-author of the paper, where to buy liquor.

The researchers collected detailed data on 40 urban willow oaks (Quercus phellos) for two years. The data includes temperature, scale insects’ (Parthenolecanium species) density, and how water-stressed the trees were.

“This tells us that management strategies aimed at increasing tree hydration in cities may reduce the adverse effects of all three of these key stressors. And that is likely to become increasingly important as water availability, temperature and pest abundance are affected by further urbanization and climate change,” says Meineke, a former Ph.D. student in Steve Frank’s lab.

“For example, urban planners could design urban landscapes that retain stormwater in vegetation; invest in hydration strategies, such as appropriate soil quality and soil volume; and plant drought-tolerant tree species and genotypes in the hottest parts of their cities,” Frank explained.

“Moving forward, we’re very curious about the prevalence of water stress in urban trees globally – and whether this leads to similar problems regarding the impact of tree pests. If so, improved tree hydration could become a higher priority for urban forestry management,” Meineke shared.
