Invasive Species 



Each jurisdiction has its own lists of invasive species. These lists can vary between the Federal Government, the Provincial Government and regional organizations such as EKISC.

Provincially, the BC Weed Control Act and Regulations lists invasive plant species that are provincially and/or regionally listed. Meanwhile, recent changes to the Controlled Alien Species Regulations of the BC Wildlife Act have increased clarity about which mammal, bird, fish, reptile and amphibian species are considered to be 'Controlled Alien Species'.

Locally, EKISC creates lists of Priority Invasive Plant Species each year. These priority species lists are carefully developed and are reflective of the realities on the ground. Since the region is divided into several different Invasive Plant Management Areas (IPMAs), priority species can often differ between each IPMA.

Curious if you have an invasive plant on your property? Need advice on how to manage it? Wondering if it's categorized as a noxious invasive weed? Maybe you've seen an aquatic invader? Check out these resources:

ISCBC Targeted Invasive Plant Solutions (T.I.P.S.) Sheets


TIPS is an information series for everyone involved in invasive plant management. Each publication focuses on best management practices and principles for operational activities or a specific species.

Global Invasive Species Database


The GISD searchable source of information about alien and invasive species that negatively impact biodiversity.

Global Register of Introduced and Invasive Species


GRIIS hosted by the ISSG compiles annotated and verified country-wise inventories of introduced and invasive species.

Invasive Alien Plant Program


The IAPP database contains invasive plant surveys, treatments, and activity plans for the entire province of BC.

Early Detection & Distribution Mapping System


EDDMapS is a web-based mapping system for documenting invasive species distribution.

Aquatic Invasive Species of BC

Site locations of aquatic invasive species occurrences throughout the province. The aquatic invasive species include species of amphibians, fishes, invertebrates, plants, alga and turtles.

Plant Answer Line

Plant Answer Line provides quick answers to your gardening questions. Using the many resources found in the Miller Library and on the Internet, Plant Answer Line is tailored to the needs of Pacific Northwest gardeners.

Great Plant Picks

Great Plant Picks (GPP) is the primary educational program of the Elisabeth C. Miller Botanical Garden. To date over 900 exceptional plants have been selected for gardeners living west of the Cascade Mountains from Eugene, Oregon, USA to Vancouver, British Columbia, Canada.

Alberta Invasive Species  Fact Sheets

Information about individual invasive species: impacts, origin, habitat, regulatory status, identification, prevention and control options. Those listed as "Prohibited Noxious" and "Noxious" are regulated under the Alberta Weed Control Act.

World's 100 Worst Database

Species were selected for the list according to two criteria: their serious impact on biological diversity and/or human activities, and their illustration of important issues surrounding biological invasion.

Japanese Knotweed Factsheet

This is one of a series of species-specific guides developed for use by practitioners (local government staff, crews, project managers, contractors, consultants, developers, stewardship groups). Together, these best practices provide a compendium of guidance which has been tested by many researchers and operational experts.

Professional Vegetation Managers Association (PVMA)

Formed in response to rapidly increasing public concern over environmental issues and a fast growing number of stakeholders in the industry; taking a more proactive approach to constantly emerging vegetation management issues. 

Legislative Guidebook

From ISCBC, this document is intended to provide guidance to land managers and stakeholders in British Columbia who are

already engaged in invasive plant management or considering becoming involved.


Invasipedia houses information on invasive plants, animals, and pathogens, and especially how to best manage them.

Invasive.Org is a grant-funded project, generated documentation of sufficient usage by a variety of user groups; they provide educational and service outreach at no cost.
