There are more than a million reasons as to why tree planting is a must for the cities. For one thing, trees improve the livability of our cities for countless benefits. However, for many years tree canopy in our urban areas has been decreasing.
Large mature trees that reach the end of their lives are often replaced with smaller species – if at all. These replanted trees then struggle to establish and reach maturity due to the demands of paved surrounds around them.
In reality, researchers have discovered reductions in both violent and petty crime. Including domestic violence through the therapeutic, calming influence of mature tree planting.
As time has gone on, more and more research has confirmed the value and benefits that mature urban trees offer our cities. Organizations such as ‘American Forests’ and ‘Trees Forever’ actively campaign in support of trees in urban areas.
What is the Purpose of Tree Planting?
On one hand, Trees contribute to their environment by providing oxygen, improving air quality, climate amelioration, conserving water, preserving soil, and supporting wildlife.
Tree Planting is the process of transplanting tree seedlings, generally for forestry, land reclamation, or landscaping purpose. It differs from the transplantation of larger trees in arboriculture, and from the lower cost. But, slower and less reliable distribution of tree seeds.
Reforestation, on the other hand, is the commercial logging industry’s answer to the large-scale destruction of old-growth forests. But, a planted forest rarely replicates the biodiversity and complexity of a natural forest.
In silviculture, the activity is known as reforestation, or afforestation, depending on whether the area being planted has or has not recently been forested. It involves planting seedlings over an area of land. Where the forest has been harvested or damaged by fire, disease or human activity.
Basically, tree planting strategies may differ widely across nations and regions and among individual reforestation companies. Eventually, it’s grounded in forest science. And if performed properly can result in the successful regeneration of a deforested area.
What are the Benefits of Tree Planting?
In the first place, trees benefit are contributed to their environment over long periods of time. By providing oxygen, improving air quality, climate amelioration, conserving water, preserving soil, and supporting wildlife.
Secondly, Because trees remove carbon dioxide from the air as they grow, tree planting can be used as a geoengineering technique to remove CO from the atmosphere. During the process of photosynthesis, trees take in carbon dioxide and produce the oxygen we breathe.
Then again, desert greening projects are also motivated by improved biodiversity and the reclamation of natural water systems. But also, improved economic and social welfare due to an increased number of jobs in farming and forestry.
Important to realize, the more mature the tree, the greater the benefits. With this in mind, below are more benefits of tree planting especially, alongside the cities;
1. Sufficient & Quality Air Supply
Notably, there is a 3-7 % ozone reduction for every 10% canopy increase in the urban. Trees are also proven to remove carbon from the air, getting absorbed and stored as cellulose in their trunks, branches, and leaves (a process known as sequestration).
Therefore, tree planting remains one of the most cost-effective ways of drawing carbon dioxide from the atmosphere. A single mature tree can absorb CO2 at a rate of 21.6 KG/year. Releasing enough oxygen back into the atmosphere to support 2 humans.
Research has also shown a 60% reduction in particulates from car exhaust fumes on streets lined with trees. Not to mention, trees can also save up to 10% of local energy consumption. Through their moderation of the local climate.
2. Increased Health & Well-Being
Notably, trees have proven to have a positive impact on a variety of health conditions. Like skin cancer, asthma, hypertension, and other stress-related illness. Especially, by filtering out polluted air, reducing smog formation, and providing shade from solar radiation. As well as, providing an attractive, calming setting for recreation.
In fact, Sulphur dioxide, nitrogen oxides and particulates, carbon monoxide, cadmium, nickel, and lead are all pollutants that trees work on. And in that case, constantly removing them from the air.
In addition, planting trees along the lanes also forms an effective sound-absorbing barrier. Particularly, to help reduce unwanted urban noise pollution. Above all, the biodiversity of trees in providing natural habitats for birds, squirrels, and other fauna are considered to some as incalculable.
3. Visual Appeal & Cooling Effects
Few things can compare with the visual impact and seasonal interest that trees bring. They offer immense visual appeal to any area and will enhance the design of any streetscape. Reducing temperatures by shade and transpiring water. In the end, this helps in reducing air conditioning bills and energy use.
After all, studies report have even proven that one mature tree can produce the same cooling effect as 10 room-sized air conditioners. Therefore, this becomes an effective tool in reducing urban heat islands and hot spots in cities.
4. Cost Savings and Property Values
For every Kshs. 100 spent on trees, there is a return benefit of Kshs. 250 received; according to the United States Forest Service.
A similar study performed in the U.K. by Natural England calculated that every Kshs. 150 spent on tree planting yielded Kshs. 750 savings. Or even, a potential £2.1 billion if taken nationally.
Independent studies have shown a consistent 5-15% increase in property values on tree-lined streets. Proving that trees increase commercial and residential real estate values.
5. Managing Stormwater & Increasing Liveability
For every 5% of tree cover in a community, stormwater runoff is reduced by 2%. By all means, preventing stormwater runoff from reaching watercourses. Especially, with harmful chemicals collected from roads and sidewalks.
Of course, tree planting in cities significantly reduces wind speed up to a distance of 10 times their height. Naturally, trees improve the livability of urban areas for many reasons.
However, for several years now, tree canopy in our cities and towns has been diminishing. Then again, replanted trees often struggle to establish and reach maturity due to the demands of engineered surfaces around them.
In other words, tree planting in urban areas faces a difficult environment. Paved hardscapes limit access to rainfall irrigation and the engineered requirements of pavement are completely opposite to what a tree needs to grow.
As an example, the adoption of GreenBlue Systems helps provide an optimal condition to give trees a fighting chance. Reaching mature in otherwise, harsh urban conditions. Equally important, soil support cells allow for generous root growth while also providing the structural stability needed for paved surfaces.
Not forgetting, ArborSystem helps in all this by bringing together the key elements of successful tree pit design. Simplifying the design and installation process for specifiers and contractors.
With all these benefits in mind, we must ensure that new urban tree plantings receive what they need. Having said that, feel free to Donate and support our projects or even Contact Us if you have additional contributions.
