Long-term experiments on invasive plants
Relatively few long-term experiments have been done surveying invasive plants in the same place, so we know relatively little about the long-term dynamics of invasive plants. A study on Canada thistle, Cirsium arvense, on burned sites in Yellowstone reveal that … Continue reading

Demand for drought tolerant plants might bring in new invasives
A research paper in Frontiers in Ecology and the Environment demonstrates how new sources of plants and demand for new plants as climate changes may lead to new invasive plant introductions. Emerging sources of nursery imports include parts of South … Continue reading

Fungi helping cheatgrass (Bromus tectorum) invasions in North America
Researchers discovered that a new fungal-plant relationship developed between cheatgrass plants (Bromus tectorum) and a fire-dependent fungus (Morchella). The fungus grows into the plant tissues and increases the biomass and seed production of the grass. More biomass leads to more … Continue reading

Using benthic barriers to stop Eurasian watermilfoil
Benthic barriers use geotextile fabric, plastic or other materials placed over the ground under water to stop the growth of unwanted rooted aquatic plants (for more information on benthic barriers see http://www.ecy.wa.gov/programs/wq/plants/management/aqua023.html). A recent study looked at how long barriers needed … Continue reading

Survey shows Maine nursery industry concern over invasive plants
A survey of Maine nursery and landscaping businesses showed that most respondents were concerned about invasive ornamental plants and tried to steer their customers towards buying non-invasive plants. Most would also support labeling of invasive ornamental plants or would not … Continue reading

Consumers willing to pay extra for non-invasive plants?
I was initially excited by the title of a new research article by Yue et al., “Do native and invasive labels affect consumer willingness to pay for plants? Evidence from experimental auctions” published in Agricultural Economics (2011) 42:195-205. But after … Continue reading
