Risk Assessments

Risk Assessment Database

Risk assessments are documents that identify, evaluate, and estimate the level of risk of a potential invasive species. They are an important tool in invasive species management, and can be used to inform prevention, prioritization, and response.

These assessments are conducted by many organizations and departments (both government and non-government) across North America and the globe to address regional invasive species threats.

Risk Assessment Database

The goal of this database is to provide a record of completed risk assessments relevant to North America. The database currently includes information on risk assessments completed by a range of government and non-government organizations (see 'Included Organizations' below). The geographical reach of the database starts with the Great Lakes region and will be expanding outwards. The database will expand to include other areas as more agencies are contacted and information is collected.

How To Use The Database

Exotic and non-native species have been compiled into this database under 5 main columns. The database can be sorted alphabetically under each category by using the small arrows on the left side of each column heading.

In the "Species" column, scientific names of species are linked to a comprehensive technical fact sheet about that particular species. These fact sheets include information on synonyms and other names that the species go by, identification specifics, size, native range, nonindigenous occurrences, ecology, means of introduction, status, impacts on the Great Lakes, and management options.

In the "Common Names" column, names of species are linked to a non-technical fact sheet that discusses the identification, size, native range, means of introduction, and status of that species.

The "Assessment" column indicates whether a full risk assessment or shortened version of a risk assessment (i.e. Ecological Risk Screening Summaries from USFWS and Categorizations from CFIA) have been completed for that species. Hyperlinks to specific risk assessments are included where available.

The "Results" section of the database is currently under construction. This section will eventually include a synopsis of the corresponding Assessment, indicating both the region that the assessment was conducted in, as well as the level of invasiveness of that particular species.
