Wolvenberg offers many advantages as a nature reserve. For biodiversity, especially urban biodiversity, it provides a vast green-blue space that promotes the recovery of fauna and flora in this densely populated area. Numerous animal and plant species live there, such as great cormorants, sparrowhawks, kingfishers, polecats, smooth and alpine newts, purple hairstreaks, a few rare clearwing moths, more than 130 species of wild pollinators, bee beetles and various species of jewel beetles, tons of pikes in the pond, almost 200 species of mushrooms, plant species such as broad-leaved helleborine and bee orchid, ... . The connection of Wolvenberg with other areas provides eco-connectivity between those areas, which also helps to prevent genetic erosion of populations. Appropriate management also allows for abundant and rich vegetation. Recent inventories showed that the area is, for example, very interesting for wild pollinators.The benefits for the population are numerous, but let us put forward the ecosystem services in the context of urban heat island mitigation and water buffering, and its major benefits for mental health as one of the few green accessible zones in an otherwise densely populated and highly paved area.
