Adaptations of native plants to invasive plants

I often get questions about what the long-term outlook is like for native plants, so it was great to see a study that looks at genetic adaptations of native species in invaded grasslands.  The authors have been studying adapations of … Continue reading

How wide to stream buffers need to be to reduce plant invasions?

Most riparian buffer regulations are set to reduce nutrient inputs to waterways, but riparian buffers also serve as habitat for native plants and animals.  Plant invasions can significantly alter riparian habitats.  A new paper by Ferris et al. looks at … Continue reading

Invasive Plant Legacies

Invasive plants can leave legacies after they have been removed, just as politicians do.  Rather than a legacy of public works or corruption, invasive plants may leave a legacy of altered soils, hydrology or new genes.  A recent paper by … Continue reading

Herbicide resistant creeping bentgrass

Another study on the potential effects of escaped transgenic creeping bentgrass, Agrostis stolonifera, is out.  This study shows that in Central Oregon wetland communities are at particular risk of invasion by creeping bentgrass and by redtop, Agrostis gigantea. Redtop can … Continue reading

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
