Trees, Science and Opinion
1st October 2012
The postings on the blog page have been few and far between of late, largely due to me being kept busy with a large tree survey of all the roadside trees in Sheffield. In light of this I thought I’d share some of this lovely document; produced circa 1947 by the Council for the preservation of rural England, Sheffield and Peak District Branch (now C.P.R.E South Yorkshire). What struck me most about the 65 year old pamphlet is how contemporary many […]

Aesthetically a large dead tree is a magnificent sight. Dead trees also provide vital habitat and the benefits of deadwood for biodiversity are massive. If a tree dies it can’t be legally protected by a Tree Preservation Order. The Woodland Trust had recently been campaigning to have the exemption for dead trees to be removed from Tree Preservation Order Regulations. They were dismayed when the new Tree Preservation Order Regulations (TPO Regulations 2012), which came into force in April 2012, still retained the exception for dead trees. For […]

Sheffield is England’s fourth largest city, with a population of over half a million. Like many northern former industrial cities it has a disproportionate share of the most deprived areas in the country. The 1980s were turbulent times for Sheffield, with massive job losses and large scale industrial action. During this time Sheffield became known satirically as the ‘People’s Republic of South Yorkshire’ in reference to the left-wing administration of Sheffield City Council, and depending upon your political leanings at the time, the term was used derisively or […]

The practice of arboriculture is ancient. The image above shows it was a subject worthy of being painted about on ancient Egyptian tomb walls, clearly showing people transplanting and caring for trees. The word arboriculture is also old; derived from the Latin arbor (tree), and cultura (tending or caring). Today the terms “Arboriculturist” and “Arboriculturalist” are both used to describe a person who practices professional arboriculture – but which one is the right word? Arboriculture was a term apparently […]

Shining spring day Falling cherry blossoms with my calm mind Kino Tomonari My street, in the North West suburbs of Sheffield, is a nice enough, but unremarkable row of 1930’s built semi-detached houses. The Cherry ‘Kanzan’ trees that line my street too, are for most of the year, fairly unremarkable. Historically one of the most planted street trees in Sheffield’s suburbs; many have now died off or succumbed to the perils of new drives and highway improvements. If […]

New Tree Preservation Order Regulations (TPO Regulations 2012) came into force in England on the 6th April 2012. England. There is a memo to go with the Regs that sets out clearly what all the changes are. The TPO Regulations 2012 aim to put all Tree Preservation Orders (TPOs) onto the same footing and consolidate much existing legislation into one new set of regulations. Essentially, the DCLG have attempted to simplify the TPO process in the new regulations, which in itself […]

Findings of a study, published as part of the Forestry Commission Research Report: Trees, people and the built environment, show that residents are happier if they live near to trees. The study compared the happiness levels of 200 tenants renting properties from a Yorkshire housing charity; half of the tenants questioned had high levels of nearby tree cover and half had few or no nearby trees. The results showed that even with everything else broadly the same, tenants with high […]

As a profession, arboriculture has much to learn from ecology. Ecological consultants have, over the last few decades, moved from relative obscurity to become a recognised established profession. Meanwhile arboricultural consultants, when asked the inevitable conversation starter “what do you do for a living?” still tend to have some explaining to do. This professionalism within ecology can be highlighted by the ecological sections of the BRE Environmental Assessment Method (BREEAM); where it is recognised that ecological work for BREEAM is specialist […]

The links between trees, forests and improved mental and physical health are becoming clearer, with an increasing amount of applied research providing a more solid evidence base. When researchers offer explanations as to why such links are evidenced, their theories tend to ultimately be grounded in psycho-evolutionary theory or what the Biologist E.O Wilson termed ‘Biophilia’. Psycho-evolutionary theory is based on the notion that millions of years of evolution have left modern humans with a partly genetic predisposition to […]

In the autumn edition of Chartered Forester magazine I had a short opinion piece published, ‘Cracking up’, which looked at the issues surrounding urban trees being removed due to subsidence claims and highlighted how the issue seems to make the tree industry so emotive. The piece provoked considerable interest and a few critical responses (generally from tree consultants who make a living from dealing with tree related subsidence claims). The latest issue of Chartered Forester featured a letter from Michael Lawson and my response which I have copied below. […]
