Invasive Alien Plant Program (IAPP)

Managed by the Ministry of Forests and Range (MOFR), IAPP is a web-based database that stores information on comprehensive invasive plant data in BC. Common use of the IAPP application minimizes duplicated efforts, facilitates more efficient development of regional or province-wide species management plans, and improves coordination between jurisdictions.

The application consists of two main components: the Data Entry module and the Map Display module. The Data Entry module enables users to enter, extract, supply and coordinate data for invasive plant management across BC, including site details, IP inventory information, planning of future activities, treatment and monitoring methods and data, as well as biological dispersal information.

The IAPP structure is based on invasive plant sites, each of which has a unique identification number. IAPP focuses on a site record itself as a geographic location, with one or more invasive plant inventory records. All activity records (treatments, monitorings, dispersals and planning) “hang off” the invasive plant they are associated with. Therefore, each site can have one or more invasive plant species, and each invasive plant can have zero, one or multiple treatments and/or other activities. Access to the Data Entry module is limited to authorized users.

The Map Display module is an interactive system used for examining IAPP’s data spatially and displays the data entered through the Data Entry module. Map Display can be accessed by anyone with Internet access at:

MOFR has prepared a comprehensive guide that explains the business of invasive plant management and describes in detail the methodologies used by MOFR. The IAPP Reference Guide, especially Parts II and III, are very helpful and readable chapters with excellent tips and answers to Frequently Asked Questions.
