Habitat Alteration and Fragmentation

Habitat alteration is a broad term that includes many kinds of changes to habitats. In this context, alteration is defined as any change in the biological characteristics of a habitat that supports a particular assemblage of species. Alteration can have beneficial, adverse, or no impact on a particular species. Examples of habitat alteration resulting from wind energy projects include changes in plant communities from invasion by weeds, increased wildfires, habitat conversion, increased human disturbance due to changes in access, and fragmentation. Habitat fragmentation occurs when large, continuous blocks of habitat are converted into smaller patches separated by project roads and features. The scale of the fragmentation and the tolerance of the species (or even local resident individuals) determine the severity of the effect. The effects of alteration and fragmentation could range from no effect on some species, to reductions in local populations, to loss of a species from the site during one or more seasons.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
