A Decision-making Guide for Invasive Species Program Managers (May 2011)
Continental Dialogue on Non-native Forest Insects & Diseases.
This guide was prepared to assist senior level program managers and policy makers in establishing priorities and making choices for invasive species management programs. While recognizing the critical and primary importance of prevention programs, the focus of the guide is the management of invasive species once they have arrived, which is an uncomfortable, but increasingly familiar role for many program managers and policy makers.

EPPO Activities on Pest Risk Analysis
European and Mediterranean Plant Protection Organization.
Risk Analysis for the EPPO region (including nearly every country in the European and Mediterranean region) which deals with agricultural, economic or environmental impacts. It can be used for every organisms and can be both species or pathway initiated. It is the regional tool adapted from ISPM 11 which is already used by countries.

BLM's Proposed Landscape Approach for Managing Public Lands
DOI. Bureau of Land Management.
Global climate change and other widespread environmental influences are affecting western landscapes. Such changes are not only of particular concern to BLM stakeholders, but such changes are also of concern for lands managed by the BLM. In response, BLM initiated "Rapid Ecoregional Assessments (REAs)" to improve the understanding of the existing condition of these landscapes, and how conditions may be altered by ongoing environmental changes and land use demands. REAs examine ecological values, conditions, and trends within ecoregions, which are large, connected areas that have similar environmental characteristics.

Plant Health Environmental Assessments

Provides plant protection and quarantine environmental documents for various species.

Eastern Forest Environmental Threat Assessment Center (EFETAC)
USDA. Forest Service.
The mission of the Eastern Forest Environmental Threat Assessment Center is to generate, integrate, and apply knowledge to predict, detect, and assess environmental threats to public and private forests of the east, and to deliver this knowledge to managers in ways that are timely, useful, and user friendly.

Secretariat of the Convention on Biological Diversity.
CBD Technical Series No. 48
This report is largely based on the 2008 Expert Workshop on Preventing Biological Invasions: Best Practices in Pre-Import Risk Screening for Species of Live Animals in International Trade (University of Notre Dame, Indiana, Apr 9-11, 2008), summarized in the report Best Practices in Pre-Import Risk Screening for Species of Live Animals in International Trade (2009; PDF | 2.01 MB), but contains additional information beyond what was covered in the workshop.

Standard Methodology to Assess the Risks from Non-native Species Considered Possible Problems to the Environment - Executive Summary (May 2005; PDF | 15 KB)
United Kingdom Department for Environment Food and Rural Affairs. Wildlife and Countryside.
In response to a key recommendation from the Defra Review of Non-Native Species Policy, Defra funded a one-year project starting in January 2004 to develop a scheme for assessing the risks posed by any non-native organism to species, habitats or ecosystems in all or part of the UK.

Conservation Gateway
Nature Conservancy.
A "one-stop" online, public library, created and maintained by The Nature Conservancy in partnership with other conservation organizations. The library makes conservation tools, techniques, and experience available to a broad community of conservation practitioners. This site is intended to foster learning and collaboration, and provide information and support to anyone making conservation-related decisions, from the staff of conservation organizations to land managers at government agencies to local land trusts to private landowners.
