Video Wednesday: Smithsonian Gardens Tree Radar Test
Smithsonian Gardens shows how they actively manage their tree collection. One of the large American elm trees at the National Museum of Natural History was being affected by disease and decay issues that were leading to its rapid decline. Using a cutting edge technology, tree RADAR testing, the tests helped to determine the extent of the problems and to evaluate the safety of the tree.
