A power plant boosts biodiversity. Does that really sound credible?

Timur Hauck, geoecologist, produces conservation concepts for wind and photovoltaic projects at EnBW and coordinates them in conjunction with surveyors and authorities.

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?

High yields
High yields

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.

Restricted
access
Restricted access

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.

New habitats
New habitats

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.

Preserving
land
Preserving land

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).

Life under modules
Life under modules

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.

Sheep maintain

Shepherds can use the site as pasture, and thus maintain the land in a natural way.

Environmental construction supervision
Environmental construction supervision

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.

Paradise for bees
Paradise for bees

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.

Regional
seeds
Regional seeds

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.

Good soil
Good soil

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.

Rare species
Rare species

The larger a site is, the more likely it is to provide habitats for rare and protected species (such as sand lizards or hoopoes).

What the business world refers to as a win-win situation simply means living in harmony in nature: The sheep keep the grass short enough to enable the so-called ground nesters to easily spot their enemies. The insects in the solar park live on the sheep dung. And the dry, poor soil keeps the claws of the sheep healthy, which are at a higher risk of endoparasites or liver flukes when the ground is moist.

If solar parks often improve the biodiversity of an area anyway, especially when adhering to the additional measures – does EnBW’s commitment still go beyond what is required by the authorities?

People are generally not given access to solar parks. Does the possibility nonetheless exist to gain an insight?
