Keeping urban habitats such as parks neat and tidy by removing dead wood and leaves is driving the species which live there to extinction.
Christmas shouldn’t be the only time of the year to have greenery in the household.
Studies show the presence of natural living things in homes improve wellbeing. So why not have your own version of a Christmas tree all year round?
Whether plastic or natural, Christmas trees are generally bad for the environment. However, a new chemical process could recycle dead trees into all kinds of useful products.

It takes a eucalyptus tree more than a hundred years to develop hollows suitable to shelter Aussie animals, and just moments to cut it down.
Valuing nature is hardly natural.
Snowpack protects tree roots and soil from harmful freeze/thaw cycles.
Climate change is shrinking winter snow cover in Northeast forests, which protects tree roots and soil from repeated freezing and thawing. This could stunt tree growth and forest carbon storage.
India has developed a pioneering national agroforestry policy.
If we need more trees, many will have to be introduced into managed agricultural mosaic landscapes.
The 1967 Forestry Act is a barrier to integrated forest management in England & Wales.

Depending on the species, touching a stinging tree can be like 30 wasp stings at once or being burnt with hot acid and electrocuted at the same time.
Xanthorrhoea have no real trunk – just tightly packed leaves.
Grass trees are wonderfully odd. They fit no neat definition, and can live up to 600 years.

Urban trees are literally made with the help of human breath – they turn the carbon dioxide we breathe out into the building blocks of plant growth. So your local trees have a piece of you inside them.

July is the hottest month in much of North America. Experts explain who is most affected by heat waves and ways to cope with them.
Mature trees have horizontal branches that are attractive to wildlife and birds.
The ecological value of old trees is irreplaceable for native Australian fauna. Identifying and preserving these trees in cities through smarter planning strategies is important for local wildlife.
There should be caution in jumping on the “forests are always better” bandwagon.
It's important to be wary of planting trees in places where none exist, or where there are significant water constraints.
It's hard to measure the value of a tree, but scientists equipped with lasers have come one step closer.
Wollemi pines once covered prehistoric Australia.
Wollemi pines have survived for hundreds of millions of years. Once covering Australia, they now survive in a few isolated spots – but they're coming back in a big way.
