In the biotope type mapping, all habitats inside and outside the built-up urban area are assigned to uniform categories, the biotope types. To do this, aerial photographs were analyzed and the urban area was scanned. The plants growing there and how the area is used are examined on site. The more precise the mapping is, the better it can be used later for planning purposes. The mapping was carried out from 2016 to 2021, using a scale of 1:5,000. To ensure that the mapping is always up to date, it should be reviewed and updated every 10 years.

In order to protect and preserve animal and plant species, it is important to ensure that they can exchange and reproduce. To this end, the city's environmental department has planned a biotope network. The biotope network map shows how valuable habitats in Wiesbaden can be connected and protected in the long term.

The basis for the assessment of the habitats was an expert opinion on the flora and fauna in Wiesbaden. In the report, animals and plants in the city area were recorded and depicted in thematic maps. The results of the report can be viewed at the following link:

Even in the past, the city climate in the spa town of Wiesbaden was considered very important for health and recreation. Wiesbaden has a special urban climate due to its basin location between the Rhine and Taunus with its stream valleys. In order to protect this, new construction projects must ensure that Wiesbaden continues to be supplied with fresh and cool air. Man-made climate change and its effects make the topic of "climate in the city" even more important. A wealth of information and specialist maps are available to find out about the urban climate and the effects of climate change in Wiesbaden.

In view of the great pressure on undeveloped areas from many different uses such as housing, traffic and commerce, it is increasingly important to protect and further develop green and open spaces in the city and the surrounding area for recreation and leisure use. For this reason, the Environmental Agency has drawn up a partial study of the landscape plan on the subject of leisure and recreation. The aim is to take into account people's current usage needs, but also to identify future trends in leisure behavior and the requirements for green spaces in the future.

The evaluation of the landscape is an important aspect of landscape planning. The aim of landscape analysis is to evaluate the visual appearance of a landscape, its character and beauty, and to understand how various factors such as nature, development and use influence the image and thus contribute to Wiesbaden's identity - taking into account both natural and man-made elements.
