INVASIVE SPECIES


S


ome of the greatest damage
to ecosystems is caused by
invasive species. These are
plants, animals, or other organisms
that are not native to an ecosystem
but introduced largely through
human action, either deliberately
or by accident. They can become
competitors, predators, parasites,
and hybridizers of native plants and
animals, ultimately threatening the
survival of those species.

The rise of the rabbit
One of the most notable species

BEFORE
1951 The International Plant
Protection Convention is set up
to prevent the introduction and
spread of pests of plants and
plant products as a result of
international trade. It is
adopted in many countries.

1958 The Ecology of Invasions
by Plants and Animals by
British ecologist Charles
Elton is the first book to be
published on invasion biology.

AFTER
2014 Studies of some of
the “world’s worst” invasive
species by ecologists at
Queen’s University, Belfast,
and Stellenbosch University,
South Africa, reveal that the
ecological impacts of these
species could be predicted
from their behavior.
