As we observe the autumn equinox today, many will have noticed that the deciduous trees around us are beginning to change colour.

🍂🍁As autumn arrives, the pigment responsible for the green colour in leaves (chlorophyll) begins to break down. This often reveals yellow pigments (e.g. carotenoids) that were there all along, masked by the abundance of chlorophyll.

Red pigments (anthocyanins), however, aren't latent in the leaf all year; they are produced in autumn and can be more prevalent in years where conditions have been favourable for photosynthesis (i.e. plenty of sun, but also sufficient water).🍂🍁

Many exciting events are happening across the world of trees this autumn! Whether you want to join a group event or take a stroll, we encourage everyone to spend some time outside observing the leaves' colours in the coming weeks!

🌳 ☀️ 🌴 Trees' capacity to cool cities is increasingly in focus due to accelerating climate change impacts. Still, the devil is in the details - species selection, planting location and good maintenance all impact a tree's capacity to deliver shade, cooling and other benefits.

By evaluating the benefits and constraints created by a site's existing green infrastructure, and considering how new landscaping specifications will adapt over the course of the development's lifetime, we help developers maximise their site's potential, including its climate resilience.

However, not all developments require planning permission, which sometimes leads to the removal of trees whose ecosystem service benefits extend beyond individual households. As a series of legal attempts to retain a significant shade tree in the centre of Freshwater (Australia) fail, residents are considering how the legal system might be changed to prevent future removal of climate-significant trees.

This left us wondering, should the UK consider additional climate-related legal protections for trees, or are our existing measures (Tree Preservation Orders) good enough?

After several failed court challenges, a council has angered a community with its approval to remove a significant tree to make way for a duplex development, but experts say local governments need to start paying more attention to residents' concerns.

The incredible return of pine martens to the British landscape is not just a source of joy for nature enthusiasts; trees could benefit too!

Pine martens are natural predators of squirrels, and research has shown they predate grey squirrels over red when both are present. Grey squirrels do a huge amount of damage to the forest economy each year and their numbers have spiralled in the last 50 years; so we welcome the return of the pine martens and hope their population and range increases over the coming decades!

Great work Hannah & BBC Springwatch!

🐛 Plane lace bug: a new arrival in London’s treescape 🌳

Having travelled across continents over recent decades, the plane lace bug (Corythucha ciliata) has now established itself in London, adding a new chapter to the story of the capital’s treescape.

Despite the insects’ fragile and delicate appearance, they are resilient, mobile, well-adapted to urban life – and remarkably robust. This minute species lives quietly on the undersides of plane leaves and is easy to overlook.

What to look for:

Adults- Feature finely patterned, lace-like wings that give them a surprisingly intricate appearance.
Nymphs- The darker, spiny, immature wingless stage provides a striking contrast beneath the foliage.

In our latest magazine, Christopher Berman (Forest Research Entomologist) shares his research, including the lace bug's lifestyle, key symptoms to look for, and crucial management tips for tree professionals.

Happy 13th Birthday to Sika - the UK's first tree decay detector dog! 🐶 🌳 🍄

Over the past decade, Sika has had the pleasure of joining Forestry England on a pests and diseases walk at Westonbirt Arboretum, and she hosted two well-attended lectures at Arboricultural Association events.

To find out more about Sika and see her in action, finding hidden fungi in trees, have a look at her webpage: https://www.crowntrees.co.uk/tree-survey-and-report/decay-detection-dog/

The last few years have seen a few new furry faces join forces with the Animal and Plant Health Agency and Forest Research - most notably Ivor, a Phytophthora ramorum detector - but we believe Sika is still the only pooch working with tree decay fungus specifically.

Happy Birthday, old girl - you deserve those sausages!

The lovely folks at Arbjobs have shared an article about the furriest member of our arboricultural surveying team, Sika!

"While Sika is not deployed routinely and is only used to identify where further investigation is warranted (and never to condemn trees), her presence reflects the consultancy’s ethos: blending traditional arboricultural practice with innovative approaches to improve understanding of trees. She occasionally assists with publicly accessible woodland or estate surveys, particularly where conditions make visual inspection more difficult, such as scenting beneath ivy or among dense epicormic growth."

If you require any type of arboricultural survey, the dedicated team of arboricultural experts at Crown Tree Consultancy are on hand to help with your enquiry via email or phone.
