Finally, biodiversity operates in the way these communities are distributed across a landscape . Each site may have something unique about it that allows certain species to live and interact there. A low-lying spot on the dry prairie collects water. Cattails spring up and red-winged blackbirds stake out a territory among them, a tiny marsh amidst the buffalo grass. Like health, biodiversity is a property we want to conserve.
Businesses diversify to lessen the impact of changes and losses.
In turn, the greater the diversity of plant and animal species and communities in an ecosystem, the greater the system's stability. The reasons for preserving biodiversity include values that go beyond needs. Ecologically , even species and processes that appear worthless or detrimental to humans have a role in nature. Beavers gnaw down valuable trees, but in doing so have an important role in creating wetlands and meadows. Though we may fear fire and seek to control it, fire is essential to the life cycle of many communities, such as a prairie.
