Controlling Para grass without herbicides
Para grass, Urochloa mutica, grows in the southeastern United States in fields, marshes and swamps. It spreads by runners to form dense stands. It can be controlled with herbicides, but managers often wish to avoid using herbicides in sensitive wetland … Continue reading

Tadpole morphology changed by Roundup
Researchers discovered that tadpoles of three frog and toad species (wood frogs, leopard frogs and American toads) developed the same tail shape that they do when exposed to predators such as dragonfly larvae or newts. The different tail shape … Continue reading

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

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
