1 The Introduction of Non-Native Species

2 Introduced Species Food webs are complex interactions among species that have developed over a long period of time. Usually, all ecological niches are filled by species that are well adapted to the ecosystem. If a new species is introduced into an ecosystem, it is unlikely to be successful at surviving. If a number of Toco Toucans (Ramphastos toco) were introduced into a temperate deciduous forest, they would likely die of starvation. Eat mostly fruit also insects, frogs and small reptiles

3 Introduced Invasive Species Food webs are complex interactions among species that have developed over a long period of time. Usually, all ecological niches are filled by species that are well adapted to the ecosystem. If a new species is introduced into an ecosystem, it is unlikely to be successful at surviving. In some cases, the introduced species may be better at surviving than the native species. Perhaps it has no natural predator in the ecosystem. If its population grows rapidly and has a negative effect on the environment, it is considered an invasive species. One example of the harmful effect of invasive species is the story of rabbits in Australia.

4 Invasive Species Human activity (intentional or not) has been responsible for the introduction of many invasive species in Ontario. Invasive species have a significant ecologically and purple economically loosestrife impact. zebra mussels sea lamprey asian long-horned beetle european starling dutch elm disease

5 Invasive Species Human activity (intentional or not) has been responsible for the introduction of many invasive species in Ontario. Invasive species have a a significant ecologically and economically impact. impact. Impact ecological economic tourism health Consequences - compete with or feed on native species, leading to decline or extinction - change ecosystem dynamics by altering nutrient cycles or energy flow - damage to forest and agricultural crops, causing lower crop yields - disease and pests may destroy livestock, crops, trees and pollinators - reduced water quality can affect wildlife viewing, fishing and recreation - clogged waterways may prevent the operation of boats - invasion of disease causing organisms, such as West Nile virus or H1N1 - pesticide use to control species may cause pollution and is a health risk

6 Controls Eliminating an invasive species is unlikely, so developing an effective control strategy is important. There are three types of controls: chemical control usually through the use of pesticides or herbicides they can reduce crop damage they can kill native species and pollute the environment

7 Controls Eliminating an invasive species is unlikely, so developing an effective control strategy is important. There are three types of controls: chemical chemical, mechanical control the use of physical barriers or removal girdling or cutting down invasive trees blocking the movement of animals with barriers

8 Controls Eliminating an invasive species is unlikely, so developing an effective control strategy is important. There are three types of controls: chemical, mechanical, biological control intentionally introducing another species can reduce the population size of the invasive species may have an effect on native species as well
