Natural Resources Stewardship staff (NRS) has determined that many non-native invasive plants (NNIs) known to present a significant threat to the quality and biodiversity of the natural areas occur in this 37,000-acre park system. To support the park mission to steward these lands, Montgomery County Department of Parks has prepared fact sheets for park managers and maintenance personnel with easy-to-read information about mechanical and chemical control methods for several terrestrial NNIs.

The goals of the California Invasive Species Action Week (CISAW) are to increase public awareness of invasive species issues and promote public participation in the fight against California's invasive species and their impacts on our natural resources.

Prevention is the most effective strategy in managing invasive species. However, hundreds of invasive plants and animals have already established in California and are rapidly spreading each year. These invaders are negatively impacting our waters, our native plants and animals (some of them rare, threatened, or endangered), our agriculture, our health, our economy, and our favorite recreational places. Help us celebrate California's Invasive Species Action Week, and more importantly, help stop the spread of invasive species, by volunteering to take action.

Landowners, we need your help: CDFW has deployed nutria survey teams from the Delta through the San Joaquin Valley and needs written access permissions to enter or cross private properties for the purposes of conducting nutria surveys and, where detected, implementing trapping efforts. Landowners and tenants, we need your help (PDF | 598 KB); so CDFW can survey for and remove destructive nutria from your properties, complete and submit the Nutria Project Temporary Entry Permit (PDF | 207 KB).

The Emerald ash borer was first found in Connecticut during the week of July 16, 2012. Since that first find in Prospect, EAB has been found in many other parts of the state, particularly in towns in central and western Connecticut. DEEP, the CT Agricultural Experiment Station, USDA APHIS PPQ and the U.S. Forest Service are working together with local partners to slow the spread of the insect and to take steps to minimize its impact. This will be a long-term effort on the part of all involved.

Utah Department of Natural Resources. 

Aquatic invasive species (AIS) personnel from the Utah Department of Natural Resources (DNR) have stopped more than 120 mussel-infested boats this year, most of which had visited Lake Powell, from launching at other Utah waterbodies. So far in 2018, more than 100 mussel-infested boats have been quarantined, a significant increase compared to recent years. "The quagga situation at Lake Powell has worsened. If you boat at Lake Powell it's very likely your boat has quagga mussels on it," said AIS Program Coordinator Nathan Owens. "With more mussels in the lake and lower water levels more boaters have mussels attached to their vessels than in past years. Our techs are regularly finding them on and in boats that have only been in Lake Powell for a day or two — something we haven't experienced in the past." Boaters that visit another lake or reservoir after visiting Lake Powell will have their boat inspected again. If mussels are found the boat will be decontaminated and quarantined, if necessary.
