TOOLS and TECHNOLOGY

Developing cost-effective early detection networks for regional invasions

A paper by AW Crall, M Renz, BJ Panke, CJ Newman, C Chapin, J Graham, and C Bargeron published in Biological Invasions (14:12), 2012.
Authors discuss the features of and methods used to develop the Great Lakes Early Detection Network (GLEDN) website. Using results from stakeholder discussions, authors provide a cost-effective framework for online Early Detection Rapid Response (EDRR) networks that integrates data and develops social capital through a virtual community. This framework seeks to provide real-time data on current species distributions and improve across jurisdictional collaboration with limited oversight.

PERSPECTIVES

Grassroots approach to conservation developed

An article by Debra Levey Larson published in College of Aces, College News, July 10, 2012
A new strategy to manage invasive species and achieve broader conservation goals is being tested in the Grand River Grasslands, an area within the North American tallgrass prairie ecoregion. A University of Illinois researcher along with his colleagues at Iowa State and Oklahoma State Universities enlisted private landowners in a grassroots community-building effort to establish a more diverse landscape for native wildlife.


RESEARCH

Long-term population dynamics of seeded plants in invaded grasslands 

A paper by MJ Rinella, JM Mangold, EK Espeland, RL Sheley, JS Jacobs published in Ecological Applications (22:4:1320-1329), 2012.
In this study, researchers introduced species from seed and then periodically measured plant abundances for nine years at one site and 15 years at a second site; their 15-year data are the longest to date from a seeding experiment in invaded, never-cultivated grassland. Results show that seeded species sometimes persist and suppress invaders for long periods, but short-term data (4 years or less) cannot predict if, when, or where this will occur. 

Invasive plant cover impacts the desirability of lands for conservation acquisition

A paper by Laura J. Martin and Bernd Blossey published in Biodiversity and Conservation online, April 22, 2012.
Authors surveyed public and private land managers to make choices between hypothetical land parcels that varied in area, plant species composition, and maintenance cost. Results reframe the economic impact of invasive plants in terms of trade-offs that are relevant to conservation practitioners. They also suggest that land managers, acting as public agents, are measurably concerned about the spread of invasive plants.
