Until recently, roots have only been studied by digging them up. Minirhizotrons allow researchers to observe root response and activity to various treatments without disturbing the root system. Root systems are the 'anchors' of the tree. Poor root development puts trees at risk to wind throw, erosion, and flooding. Root systems are one of the 'mouths' of the tree.
Roots eat and drink nutrients and water, essential for growth, from the soil.
Root systems are the 'cellars' of the tree. Roots store vital starch and protein compounds, especially during the winter. Woodland Owner Management Recommendations For woodland managers, acceptable bole size and form of trees are often primary management objectives. The above and below ground parts of the tree depend on each other. Hence, for productive stem and crown growth, landowners should use management techniques that protect or enhance the functioning of root systems.
