Invasive Species
Impacts effects
How to minimize the effects on environment
Impact and its cause
it is an organism that causes ecological or economic harm in a new environment where it is not native
Cites Page:
What are invasive species:
By:
Candace Gossett
and
Carlie Woodard
Cause:
a species that grows and reproduces quickly, spread aggressively with the ability to harm that ecosystem are given this label
doesn't have to be from another country
lake trout from the Great Lakes are entered into the Yellowstone Lake in Wyoming
A species can become invasive by:
any kind of living organism that isn't native to an ecosystem and causes harm
Direct Threats:
Indirect Threats:
Global warming makes all of these problems worse!
Positive Effects
Positive effects on an ecosystem are outweighed by the damage that is caused
Just because a species is nonnative, doesn't mean they will become invasive
A species can be invasive in one environment but non-invasive in another because of a predator species or less-than-ideal habitat conditions
Examples
The Himalayan blackberry produces edible berries that are enjoyed by the wildlife and humans
Scotch Broom was originally planted for beautification and landscaping, but now threatens to crowd out native plants and increase fire danger
Impacts cost billions of dollars each year!
When invasive species become established and begin to spread, it becomes more difficult and expensive to remove or destroy them
Dealing with Invasive Plants:

tolerating a variety of habitat conditions
growing and reproducing rapidly
competing aggressively for resources
lack natural enemies in the new ecosystem
possessing certain characteristics that ideally suit it for colonization in an area
are spread unintentionally by human activities
west nile disease in the southern states of the U.S
this video helps explain the invasive species asian carp
this video will help you understand how to minimize
the spread of invasive species from lake ecosystems to land
What they can cause:
can harm the natural resources in an ecosystem and threaten human use
cause extinctions of native plants and animals
reduce diversity
competing with native organism for the limited resources
alters habitats
affect human health and economics
displace native species
reduce native wildlife habitat
reduce forest health and productivity
change ecosystem processes
degrade recreation areas
huge economic impacts and fundamental disruptions
coastal and great lake ecosystems
preying on native species
out- competing native species for resources
causing or carrying disease
preventing native species from reproducing
killing native species young
changing food webs by destroying or replacing native food sources
decreasing biodiversity
altering ecosystem conditions by changing soil chemistry or the intensity of wildfires
we can plant native plants and remove invasive plants in gardens
learn to identify invasive species and report sightings to a local land manager
buy firewood near your camping site and leave extra for next campers
insects and plants parts can be spread
insects and plants can hitch a ride from or to your campsite
regularly clean any equipment used outside

create effective mechanisms to prevent the introductions
create monitoring systems for finding infestations
react quickly in destroying or removing an invasive species

learn which invasive plants threaten certain ecosystems

don't collect invasive plants, their seeds, or reproductive bodies
control invasive plants on your property

manage the growth of ornamental plants

avoid recreating in areas where invasive plant grow
report invasive plants to your local land management agency
