Understanding a forest’s impact through restoration

By Pamela Jonah The only concrete connection I have to Earth Day is when we took our then small children to the Boston Esplanade for a day of warm sunshine and entertainment. Right now I’m looking at snow. In April. The frigid climate, record snowfall and drawn-out winter continues to wreak havoc on Boston’s state […]

The geographic impact of imported plants

By Faith Campbell, Emeritus environmental advocate and tree-pest expert As I said in my previous post, the greatest pest risk is associated with imports of whole plants. The U.S. allows few imports of plants in soil; instead, plants must be imported a bare-root stock, which facilitates visual inspection. Still, bare-root plants can also transport a […]

Trees and Pests: A different pathway

By Faith Campbell, Emeritus environmental advocate and tree-pest expert My previous blogs examined the risk to American forests from insects introduced by traveling on crates, pallets and other forms of wood packaging material (WPM). A second pathway for the introduction of tree-killing insects and disease pathogens is imports of live plants. Close to two-thirds of […]

Strengthening enforcement to protect our forests

By Faith Campbell, Emeritus environmental advocate and tree-pest expert As my earlier blogs have demonstrated, highly damaging, tree-killing insects are introduced to North America in crates, pallets and other forms of wood packaging material (WPM). Since it was first detected in 1996, U.S. and Canadian authorities have spent more than $500 million trying to eliminate […]

Forest pests: Where is the threat?

By Faith Campbell, Emeritus environmental advocate and tree-pest expert As I said in my previous blog, many damaging pests enter the United States by hiding inside wood packaging material (WPM) such as crates and pallets. What types of imports pose the greatest risk of carrying unwanted insect pests in crates and pallets? Heavy items, such […]

The Yellowstone Club is a private ski area situated in the GYA and the forested property has had substantial mortality in whitebark […]

Shipping containers: Importing insect pests, too

By Faith Campbell, Emeritus environmental advocate and tree-pest expert Several of the most damaging tree-killing insects came to America as larvae riding in crates, pallets, or other forms of wood packaging material (WPM). These include the Asian longhorned beetle (ALB), emerald ash borer, and redbay ambrosia beetle. All entered the country since trade opened with […]

Tree-killing pests: Who? Where? How?

By Faith Campbell, Emeritus environmental advocate and tree-pest expert Nearly 500 non-native insects and disease-causing pathogens have been introduced to the United States in the 400 years since European settlement began. Here are some examples: Chestnut blight has virtually eliminated mature American chestnuts across the species’ range, which is most of the eastern deciduous forest. […]

How large does the blue spruce grow?

By Robert T. Leverett, Native Tree Society How tall do blue spruces grow? Ornamental yard trees often reach 60 to 80 feet and 1.5 to three feet in diameter. Ostensibly reliable internet sources vary greatly on listed maximum heights. Some say more than 100 feet. Others cap the species off at 80, while one source […]
