Simulation of Habitat Quality of the Lesser Spotted Eagle

The habitat model of the lesser spotted eagle depends on the degree of vegetation coverage as a dynamic changing value. To determine the habitat quality the simulation has to be repeated over a sequence of points in time (during one breeding session). The resulting habitat quality can be calculated as the minimum for the period which was simulated. (The nutrition condition is especially important in the breeding season from April to June in our region.)

Sometimes there are contradictory rules. The belief in such a rule can be changed using the weight factor. (This can arise, when more than one expert constructs a rule set.) With this fuzzy model a nutrition quality for lesser spotted eagle can be calculated. The result is shown in Figure 6.

Fuzzy model habitat

The output of the part of the model on nutrition is an input for the calculation on habitat quality. The next input is the distance to the breeding places. These places are located in a forest. To evaluate a potential breeding habitat the mean distance to the forest can be used. The last input includes the endangerment caused by wind energy plants. The lesser spotted eagle will avoid areas around wind energy plants. In this sense wind energy plants can shrink the hunting area of the bird. These three inputs are put in a new fuzzy model. The result is the habitat quality of the area. With such a

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.
