The Texas Parks and Wildlife Department (TPWD) reports that invasive quagga mussels have been detected for the first time in Texas. The quagga mussel discovery was made by National Park Service (NPS) staff at the International Amistad Reservoir in the Rio Grande basin along the Texas-Mexico border near Del Rio. Quagga mussels are a close relative of the zebra mussel, which has invaded 33 Texas lakes across six river basins since it was first introduced in Texas in Lake Texoma in 2009. In addition to being the first detection of quagga mussels in Texas waters, this is also the first finding of any invasive mussel species in the Rio Grande basin.

TPWD and partners monitor for invasive mussels in Texas lakes, but anyone who finds them in lakes where they haven’t been found before should report them immediately by emailing photos and location information to AquaticInvasives@tpwd.texas.gov.

Research offers evidence that the economic costs associated with invasive species is in large part determined by the response time between arrival of a pest and the beginning of eradication or control efforts.

Research led by Regional Invasive Species and Climate Change (RISCC) team members Eve Beaury and Emily Fusco evaluates the current landscape of invasive plant regulations across U.S.states. We've got a lot of room for improvement - especially in addressing the need to prohibit range-shifting invasive plants before they arrive. As plants continue to move north driven by climate change, the number of invasives will only increase. Unfortunately, inconsistent regulations that vary from state to state means that invasive plants have an edge on our attempts to control them. However, new research from the University of Massachusetts Amherst recently published in the Journal of Applied Ecology (requires login 🔒) suggests that we already have an answer in hand – communication.

Invasive aquatic species are known to be one of the biggest drivers of biodiversity loss, and their management especially in marine environments is incredibly challenging. To tackle this issue, the GloFouling Partnerships, led by the International Maritime Organization (IMO) and in collaboration with the International Council of Marine Industry Associations (ICOMIA), World Sailing, and the International Union for Conservation of Nature (IUCN), has published a new Biofouling Management for Recreational Boating Report [PDF, 13.4 MB]. The aim of the report is to stop the spread of invasive aquatic species which can adhere to hulls and other areas of recreational craft by addressing how to manage biofouling.

Climate change is likely to bring dozens of new invasive plants to the Northeast. Despite their invasive tendencies, many of these species are sold as ornamental plants in slightly warmer climates, but are not yet a large part of nursery sales in the Northeast. By avoiding these species, we protect our native ecosystems from future invasive species impacts. We also present alternative native plants that provide similar aesthetics while also supporting biodiversity.
