A Walnut Wonder

Recently I returned to a stand of walnut hybrid trees that I planted some years ago. I was impressed with the quality of the trees. This tree in particular exhibits all the features you want if you’re interested in growing walnut trees for their timber.Continue Reading

silvology defined

Silvology: redefining the biological science for the study of forests With co-author Jens Peter Skovsgaard I propose a formal definition for a term that describes the scientific study of forests and woods: silvology.   In contrast to other disciplines no terminology has developed to distinguish the practice of silviculture fromContinue Reading

It is Saint Swithin’s Day today, 15th July: the day on which people traditionally watch the weather.  Tradition says that whatever the weather is like on St. Swithin’s Day, it will continue the same for the next forty days. There is a well-known weather-rhyme in Britain: St. Swithin’s day ifContinue Reading

There is a very good relationship between a tree’s stem diameter and its crown diameter. This can be used in many different ways by foresters, arboriculturists and landscape planners to plan and model tree growth and …Continue Reading

On my homepage I write that I aim to celebrate the ” silvan” world: here’s an etymology. Silva or sylva is a Latin word meaning ‘wood or forest’, with silvan or sylvan meaning ‘of the wood or forest’. In forestry we use the word silviculture, meaning literally culture of forests.Continue Reading

I’m a forester.  That’s a simple description of my profession without much room for misunderstanding – or so you’d think.  Therein lies an etymological dilemma for me and my fellow tree professionals. As a forester I practice forestry, which is the management of forests.  In the public mind the termContinue Reading

message on an Ash coppice stool

It was an ancient Ash coppice stool; carpeted in green moss, fantastically gnarled and partly hollow. ” This was one our best loved trees. We are sad that you have cut it down?” Bad management or poor communication?Continue Reading

Young forest trees often require some form of ‘formative’ shaping or pruning during the first 5-10 years after planting.  I co-wrote a practical guide on this subject for Woodland Heritage, and created the artwork that I’ve reproduced here.     Young trees may require pruning for a variety of reasons,Continue Reading

I spent over a decade as a forest scientist working to improve the genetic quality of various hardwood tree species.  To put it another way, to maniupate NATURE.  It became increasingly obvious to me that we must never ignore NURTURE.  We must work with both nature and nurture when creatingContinue Reading

My forestry research work took me to the USA and Italy looking for the best ways to grow walnut trees for timber.  Foresters in both countries pioneered the planting of nitrogen-fixing trees or shrubs with hardwood trees, where their ability to improve soil fertility for ‘hungry’ species, such as walnut,Continue Reading
