What are the ecological economic and social impacts of invasive species?

The economic and social impacts of invasive species include both direct effects of a species on property values, agricultural productivity, public utility operations, native fisheries, tourism, and outdoor recreation, as well as costs associated with invasive species control efforts.

What ecological effects can invasive species have?

Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.

What effect does invasive species have on the economy?

Direct economic impacts of invasive species include management costs (mechanical, chemical, and biological), research and monitoring programs, reduced crop yield, job losses (such as in the case of reduced forestry production), damage to infrastructure, and impacts to international trade and tariffs.

What are the impacts of invasive species on human society?

reduced water quality and quantity (increased erosion and sedimentation) reduced property values. damage to private property and infrastructure. loss of traditional food and medicinal plants.

What are the 3 ways to control invasive species?

Three broad categories cover most invasive plant control: mechanical, chemical, and biological. Mechanical control means physically removing plants from the environment through cutting or pulling. Chemical control uses herbicides to kill plants and inhibit regrowth.

How does invasive species affect agriculture?

Invasive species are a major cause of crop loss and can adversely affect food security (1). In the United States alone, crop and forest production losses from invasive insects and pathogens have been estimated at almost US$40 billion per year (2).
