If you have a smartphone, the power to protect the natural heritage of New Jersey is at your fingertips! You can use it to help stop the spread of invasive plants, animals and even pathogens that threaten the natural systems and economy of the Garden State.
Environmental DNA methods are highly sensitive and accurate, making them ideal for detecting animals at low densities. However, this tool also comes with its own unique set of challenges when applied to efforts to eradicate invasive species. This research explores the use of eDNA for evaluating invasive species eradication efforts in streams and offers best practices for incorporating eDNA methods into invasive species removal projects.

Environmental DNA sampling informs fish eradication efforts: Case studies and lessons learned

New research by NOAA and partners finds that two species of invasive Asian carp -- the bighead carp and silver carp, collectively known as bigheaded carps -- could be capable of establishing populations in Saginaw Bay, Lake Huron and affecting the health of ecologically and economically important fish species such as yellow perch. The research, appearing online in the journal Biological Invasions, is based on a new model that simulates interactions between the bigheaded carps and a range of fish species, including walleye, yellow perch, and groups lower on the food web over a time period of 50 years. Over 180 non-indigenous aquatic species have already become established in the Great Lakes, with a handful of these producing substantial negative impacts. While bigheaded carps are established in watersheds near the Great Lakes, they have not yet become established in the Great Lakes.
Non-native invasive species (NNIS) pose a threat to forest ecosystems and forest productivity. Managers can play important roles in slowing the spread of NNIS. This guide describes practices to aid in those roles. The goal is to provide practices that prevent the inadvertent spread of NNIS, reducing the impacts of NNIS. The best management practice (BMP) statements in this guide are intended to apply to forest stewardship activities. This guide is intended to help managers make the most efficient use of limited resources to combat NNIS.
These maps were created to help assess impacts on nonindigenous aquatic species distributions due to flooding associated with storms. Storm surge and flood events can assist expansion and distribution of nonindigenous aquatic species through connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and/or creation of freshwater bridges along coastal regions. These maps will help natural resource managers determine potential new locations for individual species, or to develop a watchlist of potential new species within a watershed.
