Also you want to look at trees that are native to our climate. You know you might have seen shows on TV that show some really cool trees, but if they are not natural to our environment... you might not have as much luck with them.

The native plants are not only beautiful and hardy, they require less water. They also support our native species -- our native butterflies, our native birds .. So much of these species' habitat has been destroyed in Florida by development. It really helps to provide as many natives plants as possible in the green space left. They are precious areas.

When an area is disturbed, it upsets the natural balance and creates an ecological open space that gives non-natives a foothold, ... Another thing is that Florida is not very species-diverse, so there are more options for invasion because there aren't many native species.

They are top predators in their native range and we are worried about them. They are reproducing in Maryland and their biologists are tremendously concerned. They compete with native species and that is a giant negative.

The global pattern we observed suggests that plant species in species-rich regions exhibit a greater reduction in fruit production due to insufficient pollination than plant species in regions of lower biodiversity.

It?s like scotch broom ? an introduced exotic species. We can?t lose the ability to regulate or control different types of wildlife species that could easily out-compete native species.

These statistics show that the policies implemented by the Government and programmes funded and delivered by Defra, like the agri-environment schemes that now cover over 1.2 million hectares, are having an encouraging effect on biodiversity in England,

Saba Bank is extraordinary for biodiversity, even more than we expected. Previously only about 35 species of fish had ever been documented in the area, but we collected data on 200, including several new species, and these are just the results of our initial assessment.
