Invasive they destroy crops
Bears are not typically classified as invasive species; they are native to many regions where they exist. Invasive species are usually defined as non-native organisms that cause harm to the environment, economy, or human health in their new habitats. However, if bears are introduced to an area where they are not native and disrupt local ecosystems or threaten native species, they could potentially be considered invasive in that specific context. Overall, the classification depends on the bear species and its geographical context.
Pandas are not considered an invasive species; they are native to the mountainous regions of central China. Invasive species are typically defined as non-native organisms that spread widely and disrupt local ecosystems. Pandas, with their specialized diet of bamboo and specific habitat requirements, do not exhibit behaviors associated with invasiveness, such as rapid reproduction or competition with native species. Therefore, they are an important part of their native ecosystem rather than a threat to it.
Invasive plants uses natural resources originally used by native plants. In this way, invasive plants drives native plants out by depriving them of food and water. Over time, whole regions will be taken over by invasive plants, destroying the diversity of native plants and animal populations who depend on these plants to survive.
Invasive species can outcompete native species for resources like food and habitat, disrupting the balance of the ecosystem. They may also introduce new diseases or predators that the native species aren't adapted to, leading to declines in native populations. Overall, invasive species can have negative impacts on the biodiversity and stability of ecosystems.
Foxglove (Digitalis purpurea) can be invasive in some regions, especially in areas where it is not native. It can self-seed and outcompete native plants, which can disrupt local ecosystems. It's important to check with local authorities to see if foxglove is considered invasive in your area.

Red foxes are only considered invasive in Australia where they were introduced from Europe by early settlers. They are not natives of Australia and have no natural enemies there. The population exploded and the red fox started to decimate local native wildlife populations..
Many types of butterflies are migratory. Therefore, they would be native, and NOT invasive.
A species is not inherently native or invasive. All species on Earth have a region to which they are native. If they are introduced to a new area, then they are invasive to that area. The orca has a cosmopolitan distribution, so it is native to oceans pretty much everywhere.
An invasive animal
The weeping willow is native to China, but it has been introduced to various parts of the world as an ornamental tree. In some regions, it can be considered invasive due to its fast growth rate and ability to outcompete native vegetation.
No, raccoons are not an invasive species of the Everglades. They are native wildlife there.
Is the short sedge grasses native or invasive to a humid continental climate
Victor Ramey has written: 'Invasive and other non-native plants found in public waters and conservation lands of Florida and the Southeastern United States' -- subject(s): Identification, Invasive plants, Alien plants
"The Snake That's Eating Florida" explores the ecological and economic impact of the invasive Burmese python in Florida. The book examines how this non-native species disrupts local ecosystems, preying on native wildlife and contributing to significant biodiversity loss. Through a blend of personal narrative and scientific research, the author highlights the challenges of managing invasive species and the broader implications for conservation efforts in fragile environments.
It is not a native plant and it crowds out native plants.
There is no such thing as an "invasive koala". Koalas are not invasive as they are native to Australia, and have not been introduced to any other country.
