Jen- Well here's one of many definitions of silviculture, one used by a past employer of mine:
"On the Daniel Boone National Forest, silviculture is practiced to provide the greatest good to the greatest number of the citizens of the United States while ensuring that the land is not degraded. The practice of silviculture starts with knowing what currently exists in an area of the forest. Collecting this information is called inventory. After inventory describes what exists in an area, we can begin to compare what exists with what is needed in an area. If there is a difference between the two, activities may be conducted in the area to ensure that the identified needs are met. These activities are called treatments. Treatments are only implemented after we try to determine what the public wants from the forest and we analyze what effects the treatment will have on the forest. This is called planning Yes, the assumption is that you're referring to a culture (sociologically, cultures are always more than one individual) of trees, or as we call them a population, a stand, a forest and ultimately a forested ecosystem. To deal with a population, without measuring all of them (called mensuration in forestry jargon), statistical methods are employed (involving the field of bio-statistical analysis). A forester has to know the growth tendencies of individual tree species in a culture, and that involves silvics. Once a forester has a grasp of these things in a stand (homogeneous group of a "like" community) the forester can put together a silvicultural prescription and hopefully 'steer' the stand towards a goal, whether it be ecologically based, sociologically based, economically based, or whatever goal the land managing agency or entity is "invested in". -Don To: [email protected] Subject: Re: [ENTS] Re: More French Tree ID please Date: Tue, 8 Dec 2009 11:00:29 -0500 From: [email protected] Scott, When I saw these trees, I thought of Longwood! So "pollarding" is my word of the week. I hope my friend sends more pix of trees from Paris as it's so interesting to compare displays and methods of pruning. Would the pruning of street trees in a given area be considered "Silviculture" or is that only when there is at least a stand?

Other favorite species for Pollarding are Little Leaf Linden and Norway Maple. Maybe a Sycamore Maple (Acer pseudoplatanus) Longwood has a couple Allees of pollarded trees.
