A power plant boosts biodiversity. Does that really sound credible?
How come? To start with, such projects are generally built on agricultural land.
What is different about a solar park?
Is it even possible to objectively assess the impact of solar parks on the visual landscape?
Are the measures for greater biodiversity the same for every solar park?
Huge technical progress has been achieved with the modules: We can now generate twice as much power on the same area as we could ten years ago.
Plants and animals live undisturbed because humans and larger animals have no access. Fences generally have a distance of about 20 cm to the ground so that small creatures can still get into the solar park (so-called small animal passages). In some regions, a so-called wild boar-proof fence must be built to protect flocks of sheep from wolves.
Hedges and shrubs are planted in order to connect individual habitats with one another and create high-quality structural diversity (a biotope complex) aimed at species conservation.
A solar park seals less than 1% of its total area. Only the posts for the modules take up space. At very large solar parks, fixed stations may be added (inverter station(s) / transformers).
Plants and animals also live beneath the modules because light can also get through here. What cannot be seen from above is the fact that there is clearance to the ground of at least 80 cm. The abundance of insects is an important food source for many breeding bird species.
Shepherds can use the site as pasture, and thus maintain the land in a natural way.
Many construction projects are supervised by independent environmental specialists. They monitor whether conservation measures are carried out properly and in compliance with laws and regulations.
The honeybee is one of the most important working creatures of all and, like many other pollinating wild bee and insect species, it will find a diverse paradise in the solar park. Regional honey is obtained from some parks.
We sow regional seeds. This creates a new and natural habitat adapted to the location for many plants and animal species – sustainably and often for over 20 years. Depending on the location, an especially high density of species can be observed among grasshoppers, butterflies, reptiles and breeding birds, in particular.
A solar park is like a health cure for the soil: Fertilizers and pesticides are not used, and the site is not managed by any mechanical equipment such as tractors. Humus increasingly forms, which not only binds CO2, but also increases the fertility of the soil in the long term.
The larger a site is, the more likely it is to provide habitats for rare and protected species (such as sand lizards or hoopoes).
