Whatever the Weather: Trees for our future climate. By Caroline Bennett, Education Officer

Thursday, February 14th, 2013

Join our Learning Team for the ‘Whatever the Weather’ family trail around the arboretum this half term (between 12-14 February) to discover how trees survive in all sorts of weather, how trees can change the weather and what we are doing to prepare the arboretum for a changing climate.

Scientists expect that the British climate will become drier and hotter.

Westonbirt Arboretum is creating a one hectare site to trial species from different origins to see how they survive in our changing climate. This is called the 2050 Glade, which is close to the junction between Lime Avenue and Loop Walk in the Old Arboretum.

Ten initial species have been planted, including a field maple collected from seed in Turkey. Around half have survived the harsh winter. Field maple is a species native to England and it will be interesting to see whether the plant collected in Turkey performs any differently.

Other species to be tested are the Turkish sweetgum, the Kamila tree and both the Chinese and Japanese Tallow tree. Three of these trees may be suitable substitutes for autumn colour providers, such as maples, that might not do so well in a warmer climate.

You can find out more by visiting the Great Oak Hall to pick up a trail map and taking part in our free fun activities at the Learning Centre between 11am and 3pm, 12-14 February.

Whatever the Weather: Missing home comforts. By Caroline Bennett, Education Officer

The eucalyptus at Westonbirt Arboretum is a long way from home. Native to Australia, its normal climate is very different from our own.

It survives well here in the UK, but it doesn’t like the frost. Many eucalyptus trees don’t tolerate temperatures below -5C. So how is this one still alive?

The Holford family, who created Westonbirt Arboretum, planted a shelter belt of evergreen trees like yew and hemlock around the edge of the arboretum to protect more delicate trees from cold winds and frosts. We still lose trees due to cold weather from time to time, but the shelter belt helps to reduce this.

Whatever the Weather: Can a tree predict the weather? By Caroline Bennett, Education Officer

There is a lot of folklore surrounding trees as weather predictors. It’s hard to separate the myths from the science, as some people say that trees do react to changes in air pressure and humidity that we humans can’t detect. Here are some tree predictions, why not test them out for yourself?

“When maple leaves curl and turn bottom up in a blowing wind, rain is sure to follow”

“Open pinecones predict dry weather and closed pinecones predict rain”

“The first bloom on the horse chestnut tree indicates that winter is over and there will be no more cold weather”.

“If the oak flowers before the ash, we shall have a splash. If the ash flowers before the oak, we shall have a soak“

Whatever the Weather: Surviving life in a freezer. By Caroline Bennett, Education Officer

Although their branches may seem delicate, birches are one of the toughest tree groups around. In fact they’re so tough they can survive even if their trunks freeze solid.

The secret behind their survival is the removal of water from their living cells – after all if there is no water to freeze, ice can’t form!

Pores in the walls of their cells allow water to move out of the cells and into the spaces between them, where it freezes. However, the pores are too small for ice to move back into the cells, protecting the cells from freezing. This method is so good, some trees can survive temperatures as low as -196 degrees celcius!

Whatever the Weather: Urban Lungs. By Caroline Bennett, Education Officer

Today we are beginning to realise the many ways street trees and parks make our cities nicer places to live. Plane trees (such as this one below) are particularly suited as they are highly tolerant of pollution.

Thanks to evaporation from their leaves, trees can help cool city temperatures during the summer – by as much as 6 degrees celcius in hot climates.

In winter they act as windbreaks helping to conserve heat. This reduces the energy required for heating and cooling. In addition their leaves help to clean the air and reduce noise. This promotes healthier communities – in fact a study showed that settings with trees lowered stress and blood pressure.

Whatever the Weather: Huff and puff! By Caroline Bennett, Education Officer

The wind is a major cause of tree death. Yet trees can grow in extremely windy areas – if they have the right shape and flexibility!

Where strong winds blow from one direction, ‘flagging’ can occur.

This is where the branches grow only on the downwind side of the tree. Some trees even grow flat along the ground.

Other trees like the palm are very flexible and can bend right over. This allows them to even withstand hurricanes.
