This manual contains three types of activities. First there are introductory, or awareness-building, activities. The second type focuses on both beneficial and detrimental characteristics of exotics. And finally there are activities intended as reinforcers. The best advantage can be gained from this set by selecting at least one introductory activity and several from the second set and following up with routine monitoring of a nonindigenous species in your community.

This booklet is the 2019 revision of a similar booklet published in 2001 and the second edition. This updated edition of the guides provide management suggestions for most listed species based on a synthesis of field trials and greenhouse experiments mostly conducted in the arid southwest. The second edition included most of the invasive plant species that appeared in the 1st edition with several species added. The updated booklet is not intended to provide a comprehensive list of all of Arizona’s invasive weeds, but rather, it illustrates a few invasive plants that have become, or have the potential to become, problematic in Arizona.

North American Bat Monitoring Program.
Launched in 2015, the North American Bat Monitoring Program (NABat) is a continental program that monitors bats at local and range-wide scales. NABat monitoring efforts focus on the 46 species of bats shared by Canada, the United States and Mexico. NABat provides reliable data to promote effective conservation and long-term viability of bat populations and is jointly led by the U.S. Fish and Wildlife Service and the U.S. Geological Survey. Participating members include U.S. Forest Service, National Park Service and other federal, state and provincial agencies in the U.S. and Canada, local and regional agencies, native Tribes, academic institutions, businesses and conservation organizations.

White-nose syndrome has killed over 90% of northern long-eared, little brown and tri-colored bat populations in fewer than 10 years, according to a new study published in Conservation Biology.

In 1946 the Argentine Navy imported 10 beaver couples from Canada and set them free in Isla Grande, the deep south of Tierra del Fuego, with the intention of "enriching" the native fauna and the local fur industry. The consequences of such initiative were disastrous: Protected from hunting for 35 years, and devoid of natural predators, the beavers grew over 5,000 times their initial population, caused irreversible changes in the forest ecosystem, and started advancing over the continent. Now, a study published in Chilean Natural History suggests that the demographic explosion of those beavers could be bigger than suspected because it can take years or even decades for local inhabitants to notice the rodents' presence and their impact on the surrounding ecosystems.

This tool is designed to help users differentiate between invasive hornets, specifically Asian giant hornet, and other common non-targets found in the U.S., including bees and wasps. Included are fact sheets and a filterable image gallery that can be used as a rudimentary key.

ITP is pleased to announce the release of North American Hornet Screening Tool. Hornets in the genus Vespa play a critical role as predators in their native habitats, but in North America these species may have a disastrous impact on agriculture by reducing populations of important pollinators such as the honey bee. Hornets also pose a serious health risk to humans because of their powerful sting. North American Hornet Screening Tool is designed for anyone who may encounter these species in the U.S., including the Asian giant hornet (AGH, V. mandarinia).

North American Hornet Screening Tool includes fact sheets and an interactive image gallery to support screening for Asian giant hornet and other potentially invasive hornet (Vespa) species. The interactive gallery can be used as a rudimentary key: by choosing one or more of the filters at the top, you can easily narrow down the images to only those that may match your specimen. A more in-depth version of this tool providing specialized information for identifiers on all exotic hornet (Vespa) species, will be released in 2022.
