Participatory testing will enable citizens to be actively involved in the NEB process for improving urban biodiversity. Pilot testing will include the operation of BIOCENTUM nodes and the bottom-up selection of innovative ideas. Young talents will be particularly encouraged to propose their visions and biodiversity solutions.

This guide provides a methodology for establishing and operating local BIOCENTUM nodes (Biodiversity-Centred Urban Mindset). Based on the Living Lab approach and the values of the New European Bauhaus, these nodes serve as participatory platforms where municipalities, experts, NGOs, businesses, and citizens jointly identify local biodiversity challenges and co-create solutions. The guide also offers a framework for awareness-raising, capacity-building, and testing of nature-based interventions, supporting cities in integrating biodiversity into urban planning and decision-making processes.

These procedures will guide cities in shifting citizens’ perceptions from ambivalence to active support for urban biodiversity. A step-by-step approach will show how to use participatory, green, and aesthetic solutions for biodiversity improvement. The procedures will also integrate the “aesthetic” dimension with biodiversity goals.

Once the pilots are completed, mutual peer-review will be carried out in pairs between the project partners (Pula–Kranj, Wrocław–Érd), using the NEB+ Compass. The testing reports will capture both good and bad practices, helping to refine biodiversity projects and strengthen their acceptance in an international context. Pilot actions will be evaluated using the New European Bauhaus+ Compass. The NEB+ Compass is a transnational evaluation tool designed to align pilot interventions with the three New European Bauhaus values – sustainability, aesthetics, and inclusiveness – while adding a strong focus on biodiversity. It sets out criteria and indicators for assessing how urban projects contribute to ecological regeneration, community engagement, and cross-sectoral collaboration. The Compass also enables partner cities to peer-review their interventions, monitor progress, and ensure that implemented solutions enhance both biodiversity and social well-being.

Drawing on the experiences of pilot implementation and testing, four NEB-based Urban Biodiverse Transition Roadmaps will be developed. These will serve as an important tool for other cities wishing to implement solutions that combine biodiversity with the New European Bauhaus concept. This approach will ensure wide dissemination and opportunities for “learning from others.”

Four Local Implementation Plans were developed for Kranj (Slovenia), Érd (Hungary), Wrocław (Poland), and Pula (Croatia). Each plan outlines pilot interventions addressing specific biodiversity challenges, such as creating biodiverse islands for endangered species, supporting keystone species through micro-interventions, preserving natural wildlife patterns, and introducing edible plants into urban spaces. The plans combine local climate adaptation strategies, participatory approaches, and spatial planning measures, demonstrating how biodiversity-oriented design can be embedded into municipal policies and community practices.

A strategy will be prepared to provide cities with direction in promoting new forms of urban green transition across different sectors, with the aim of delivering tangible, real-life investment examples.

Action Plans (Wrocław, Kranj, Pula, Érd) will define realistic, result-oriented objectives and short-, medium- and long-term targets for the biodiverse transition. They will propose specific measures, identify key stakeholders and financial resources, and suggest necessary adjustments.
