Economic costs of invasive species are much lower when funds are invested in prevention and early detection efforts. Once an invasive species spreads, management is exponentially more expensive and less efficient. Between , we reached out to Ontario municipalities and conservation authorities via phone and email to find out how much they spend on invasive species each year.
We received data from municipalities and 23 conservation authorities specific to the most recent fiscal year or annual expenditures. This report estimates how much Ontario municipalities and conservation authorities are spending on invasive species, but this is just a fraction of the economic impacts of invasive species. Our study found that municipalities and conservation authorities are spending the most money on emerald ash borer. The next highest expenditures for municipalities are zebra and quagga mussels and Ldd moth.

These invasive species arrive, often accidentally, from elsewhere in the world and, in the absence of natural predators, kill, crowd out or otherwise devastate native species and their ecosystems. Invasive species have the ability to severely alter a landscape and ecosystem.
This not only puts native species at risk but also how the land is being used. This report examines the benefit of investment into the urban forests in Toronto and how much should be spent to maintain them. A Value of Urban Forests in Cities across Canada This report examines the economic and environmental benefits of forests in and around Halifax, Montreal, and Vancouver.
Invasive Species: A Costly Catastrophe for Native Biodiversity This study looks at the public cost of invasive species that are brought in for ornamental use but spread to the natural environment. Invasive species, those introduced and spreading outside of their native range as a result of human activities, are a growing threat to environments worldwide. Environmental impacts of invasive species, one of the main causes of biodiversity loss, are well-studied.
However, few studies have summarised their economic impacts. This study is the largest and most up-to-date combination of economic costs of biological invasions in the UK. The results have been published in the journal NeoBiota. Invasive species have a major effect on many sectors of the U. Their presence impacts animal and human health, military readiness, urban vegetation and infrastructure, water, energy and transportations systems, and indigenous peoples in the United States.
They alter bio-physical systems and cultural practices and require significant public and private expenditure for control. This chapter provides examples of the impacts to human systems and explains mechanisms of invasive species' establishment and spread within sectors of the U. InvaCost is the most up-to-date, comprehensive, standardized and robust data compilation and description of economic cost estimates associated with invasive species worldwide.
InvaCost has been constructed to provide a contemporary and freely available repository of monetary impacts that can be relevant for both research and evidence-based policy making. The section below contains highly relevant resources for this subject, organized by source. Or, to display all related content view all resources for Economic and Social Impacts. To better understand the impacts of invasive species on infrastructure managed by the federal government an effort was undertaken by the National Invasive Species Council Secretariat to solicit feedback from those agencies.
A questionnaire was sent out to the federal agencies that manage infrastructure to identify the impacts they have observed, how they are managing them, issues they have identified and resource needs. The research demonstrated that impacts from invasive species on federally managed infrastructure range from non-existent to significant. Identified gaps needing improvement include awareness and education of invasive species impacts, limited resources, insufficient policy, and lack of agency support.
National Oceanic and Atmospheric Association. This guide will assist Pacific island practitioners to use the costs that result from invasive species incursions to gain support to fund prevention, management, restoration, research, and outreach.

Invasive alien species are more often than not pigeon-holed as an environmental or biodiversity issue, and consequently — especially in developing countries — do not receive due recognition by policy-makers.
Yet the reality is that they are a major threat to human livelihoods, especially to agriculture and therefore food security, and are generally undermining human well-being. Moreover, ongoing globalisation and increasing trade are escalating the problem to critical proportions.
We hope that this booklet will contribute towards a better understanding of these links and to placing invasive species firmly on the development agenda. National Wildlife Research Center. Managers often struggle to calculate the ecological and economic costs associated with invasive species. Yet, knowing these impacts can boost support and understanding for invasive species management.
Stephanie Shwiff and colleagues describe how economists determine costs of both primary and secondary impacts from invasive species and how these translate into jobs and revenue in regional economies.
What losses would corn and soybean growers experience if they were forced to eliminate herbicides and other control techniques from their weed management toolbox? Skip to main content.
