Water hyacinth used for counteracting algal blooms
In a controversial experiment in Florida, researchers are stocking King’s Bay with floating pens of water hyacinth (Eichornia crassipes) to reduce algal blooms. Water hyacinth was removed from the bay beginning in the late 1950s, but Hydrilla replaced it and … Continue reading

Forest Fragments in Managed Ecosystems Study – Invasive plant habitat projects
At the Delaware Invasive Species Conference this week two Delaware researchers presented some preliminary findings from research done through the FRAME long-term ecosystem study in northern Delaware. Ph.D. candidate Solny Adalsteinsson is finding more ticks under multiflora rose than uninvaded … Continue reading

Composting invasive plants
Composting invasive plants has to be done carefully to fully kill seeds and other potential propagules. Researchers in Texas built a composting facility to handle wetland invasive plants and report on their experience in an article in Invasive Plant Science … Continue reading

Factors that make temperate forests susceptible to invasion
Higher light availability, later spring leaf-out, and higher soil nitrate levels in intact forests all correlate with a greater abundance of invasive plants. The authors of this study looked at interior forest understories where different canopy species resulted in different … Continue reading

Invasive grasses selfish in soil conditioning
A greenhouse study on native and non-native grasses from the Great Basin looks at changes in soil nutrient levels and soil microbes among species. The researchers found that although both native and non-native grasses condition soils, the changes caused by … Continue reading

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

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
