Help protect street trees!

Since the residents of Sheffield took to the streets to slow down an over-zealous council from removing multiples trees, there has been more awareness growing of the benefit these large urban organisms provide for us.

The economic value they provide has been previously written about in this blog, with work done by the Trees and Design Action Group highlighted.

Your thoughts on protecting street trees are needed, and currently the Woodland Trust is running a consultation where you can tell Defra how you feel.

Please click over here to submit this consultation (already prepared).

‘Star’ status and Merry Christmas!

After working with the National Citizen Service for another summer with The Challenge and re-connecting young people to Nature, Teratrees has been rated a STAR partner after excellent feedback!

STAR status!

We believe it is our relationship to Nature that counts. This is at the root of our environmental woes. 

As the last post for the year, we would also like to wish you a merry Christmas and a great festive season.  As a last thought for the year, we also ask you to think about what your relationship to Nature is, and what this means for how you will act in the world.

Best wishes.

Winter is Coming!

Nature is the law of balance in action. After fresh growth and longer days of light, plants and trees prepare for colder weather. Deciduous trees save the energy maintenance of keeping leaves alive which would otherwise have less photosynthesis in conditions of a light deficit. They withdraw nutrients and through the chemical reactions of sugars and tannins the leaves turn colour and fall. Metabolism slows and the roots become more dormant in the cold. This is actually a good time to plant a tree, as the tree has less demand for nutrients and water, and is less shocked by a new environment. 

Resilient Nature

While humans scramble for layers of clothing and turn on heating in their homes, trees stand naked in the chill,  with hardy specimens handling temperatures down to – 70 °C through the production of proteins that allows the space between cells to freeze, rather than the cells themselves. These temperature decreases are also good for killing pests and disease that would harm trees.

Trees are well prepared to handle cold weather. However, they do struggle with sudden fluctuations.

Climate Change

With the increasingly unpredictable temperature fluctuations and the increase in milder winters in some parts of the world, trees have less time to adapt. This will result in the death of more species due to periods of extreme cold, as well as to pests and disease from milder winters. More adaptable trees and exotic species will also migrate to new areas, as new habitable regions appear for them. In years to come we will see there has been a large shift in species migration.

Calming the mind with Nature

As the scientific evidence begins to mount, much of it points to the old adage of when feeling down to go take a stroll in the woods. Being in close proximity to trees has shown positive effects on mental illness, ADHD, concentration levels, depression and reaction times. This has been written about by Matthew Silverstone in Blinded by Science (2011), where he looks at various aspects of Nature and the interaction with human mind and body. Essentially, tree hugging is not so laughable with the studies showing measurable decreases in the symptoms of stress. Also expanded upon in the book is that children benefit greatly from being around green plants, showing improved cognitive and emotional function, as well as creativity. If we take a step back, is this so surprising? We have spent far more of our evolutionary history in natural environments compared to our modern homes and offices. Our genome does not forget that easily.

Connecting Young Adults with Nature: Team Emeke of the NCS

On another beautiful day of this British summer, a group of young adults arrived ready with filled water bottles and lots of enthusiasm to plant  30 silver birches in Roundwood Park. The fundraising for this campaign had been successfully completed by this group, who named themselves Team Emeke. This is an ongoing partnership with Teratrees and the National Citizen Service (NCS). One of Teratrees’ objectives is to connect future generations with Nature, and today it was successfully accomplished, along with some urban greening!

Urban Greening with the NCS

On Friday a group of young adults got their hands dirty and transformed a rockery in Roundwood Park in London. This was not easy going with hard soils from the heat wave, but with a bit of persistence and team effort an array of colour and variety was introduced, with apparent satisfaction from this team participating in The Challenge, as apart of the National Citizen Service (NCS).

Teratrees is a partner organisation for the NCS, with our objective of connecting young people with nature and greening London landscapes.

National Citizen Service Launch Teratrees Campaigns

During summer and half-term the National Citizen Service (NCS) run a programme for 15 – 17 year olds called The Challenge. This three week set of activities (indoor and outdoor) helps build skills, confidence and a way to make friends. Continuing on from last year the NCS will be using Teratrees as a partner organisation for some of the outdoor activities – in this case planting trees in the parks of London!

National Citizen Service

Hopefully there will be some rain to break up the heat wave, however, the young trees planted will be watered appropriately. Summer is never ideal for tree planting, but the species chosen (silver birch) are more resilient when planted together as a grove.

Starting off a campaign, the 2018 Perham team (Peratrees) have launched a campaign on the platform and can be found by logging in to the Teratrees website and viewing the campaign tab. Each tree is 100 Tera, which is £5. Tera will need to be purchased before supporting their campaign.

Across Western and Eastern Europe, North and South America, the Balkans, Russia and China and many more cultures, they all celebrate in various ways the joys of midsummer and the summer solstice. These celebrations go back to ancient times when humans were more connected to the cycles of the Sun, Earth and Moon.

In ancient Greece, the summer solstice marked the one month count down to the Olympic Games, while before Christianity, European pagans welcomed midsummer through massive bonfires.

In England, the place to be is Stonehenge, and many people, including neo-pagans, neo-druids and tourists, gather to watch the sun rise as the ancient people did 5,000 years ago.

Humans have always been connected to the cycles of nature. Perhaps this is being remembered.



Planting in Summer

Traditionally October to March are better months for planting as tree root systems are dormant and less water is required. However, sometimes planting is needed in summer and for these occasions it is important to manage the watering:

  • build up watering slowly, be careful of over watering
  • do not try to make up for missed watering sessions by increasing watering
  • deep watering sessions are generally better every few days – think of a good rainfall!
  • avoid the heat of the day to minimise evaporation
  • use mulch to further minimise water loss
  • avoid fertilizers in summer, these can burn the tree when there is a lack of water
