Summer Scorchers and where are all the Trees?

With the UK currently in the midst of a heatwave the normally water logged country is getting a true British Summer. However, the heat is not for everyone our four legged friends can suffer and some die in the heat the weather does not always suit the elderly or certain industries (agriculture, horticulture). Many of us are suffering from hot offices due to air conditioning units being turned off because of Covid.

What’s the solution? Trees!

They offer shade for us and shelter for wildlife and a forest can be a number of degrees cooler then a field as it collectively absorbs the heat and light. So first of all looking at shade.

Trees can block nearly ninety percent of light and heat from our environment by offering shade and acting like a parasol. On top of this it cools the ground by shielding it from the sunlight. By allowing the ground to be cooler it encourages heat loss from us and our surroundings. This can have a relative affect of us feeling around eight degrees cooler celsius. Which is why both us and animals shelter in urban oasis’s or flock to the cooler countryside. For those in largely glass offices the benefit of planting across the suns path and incorporating this into the design process of the building shields you and the workforce by stopping or reducing light penetrating the windows. Some studies have looked at the benefit of trees vs air conditioning costs but this is only in the early stages of research. This is an important fact for countries like the UK as many of our homes do not have air conditioning and for those looking for a zero carbon solution to cooling their houses natural shade could be an option. 

Now heat in the urban environment vs the country can be more noticeable as the largely glass and concrete buildings can increase the suns intensity. Solutions such as the living walls could offer solutions for both nature in a urban environment and heat absorption. In the countryside we have the luxury of a cooler environment but as planning increases house building we need a green plan to establish flora as an essential part of our environment. Evapotranspiration occurs on all trees but in urban trees as water evaporates off of their leaves it cools them and us as a secondly affect as the process uses the light and heat energy to evaporate the moisture. 

Not all trees are created equal when planning your projects you need to think about the climates of your area. What type of soils do they thrive in? What type of buildings are they near to as you do not want the trees to damage infrastructure and subsequently get removed. Are the trees you are planting tolerant of your climates extremes some will tolerate droughts but not floods and plants like any species should be native in the first instance. If they are of a different variety make sure they are sourced from a registered company and seller.

Now trees and other natural tools can offer us a valuable resource other suggestions to use them to enrich local areas by producing fruit which are for all in the community is another possible avenue to explore.
