Increasing Biodiversity with Moss in the City
Contributing to “local urban climate improvement” is also one of our goals at Green City Solutions. Within this framework, our moss filters can contribute to the preservation of biodiversity in addition to air filtration and cooling. As is currently the case in cities like Braunschweig and the municipality of Bestensee near Berlin, our CityTrees are being enhanced with additional greenery, thereby serving as an important element in increasing urban diversity.
The local fresh air zones in Braunschweig are located, on the one hand, on a median strip of a main road into the city and, on the other hand, next to a bus stop at one of the main traffic junctions in the inner city area. The air is thus cleaned where it is polluted and street trees have no place for sustainable, healthy root growth. The seating surface of the CityTrees, which also functions as a water reservoir and foundation substitute, can be partially or fully greened on request.
The surrounding greenery of low-growing perennials, flowering plants, grasses and solitary plants can be visited and used by insects.
Placed in a network, CityTrees can connect distant urban biotopes, helping to preserve the biodiversity of fauna-flora habitats in cities.
In addition to the surrounding greenery, the mosses themselves also play an important role. Although they may seem “small and inconspicuous”, mosses are assumed to hold a relevant position “in the ecosystem in various respects” (source). Swissbryophytes referred to them as ” a small city in a small space” (source), as they provide a “habitat for small and smallest” (source). Moss serves as food and shelter for a variety of insects, including bees, butterflies, and beetles. In other habitats, mosses perform pioneering work regarding soil formation and “prepare the way for the growth of flowering plants”, they are “regulators of the water balance”, peat mosses are “builders of the raised bogs” and thus “contribute significantly to mitigating the greenhouse effect”.
