Biodiv is the first tool to digitalise CLIMB calculations, enabling time-efficient scenario analysis of impacts on biodiversity – both negative and positive. The platform is designed to be used by a wide range of actors in land use and development, with a focus on user-friendly calculations and clear decision support.

The CLIMB metric is the foundation for all calculations in Biodiv.

No. The interface is built to be accessible, while resting on robust ecological methodology and correct input data.

Yes, CLIMB is open source. Biodiv makes the workflow faster, simpler and more reliable than working manually in spreadsheets.

Biodiv digitalises the manual and complex calculations in CLIMB, making them faster, simpler and more reliable. For example, Biodiv imports data directly from nature value assessments and project designs. Calculating area changes in CLIMB is also time-consuming – something Biodiv makes dramatically easier.

Most users are up and running with the core features of Biodiv within a few hours. If anything is unclear, we are happy to provide personal guidance.

The calculation itself is just a few clicks away, but if your geodata is disorganised it will need to be cleaned up first. We can help you with that.

At present Biodiv supports only the CLIMB metric, the only one so far to have gained wide adoption in the Nordics. We plan to add further metrics to Biodiv as they are developed.

Getting used to a new unit for nature is like getting used to a new currency. Here are a few very different examples: A new detached house with a garden on land with moderate nature values: a loss of about 0.2 CU, or 200 mCU. A new 20,000 square metre industrial site on land with very high nature values: a loss of about 35 CU. A new 10 km stretch of national road through varied land with moderate and lower nature values: a loss of about 15 CU.

Biodiv requires the following input data: 1. NVI (nature value assessment) data as a shapefile or GeoPackage, with geodata for the seven NVI classes included in CLIMB. If the data only covers NVI classes 1–4 (or only classes 1–3), the remaining classes need to be estimated from satellite imagery etc. for a complete calculation of the whole project area. Calculation biotopes can be defined from an NVI, and additional information about calculation biotopes is ideally recorded while the NVI is carried out, as an addition to the standard. 2. The impact area as a shapefile or GeoPackage. The geometry and the type of impact (building, road, gravel pit, etc.) are sufficient. 3. If ecological compensation is to be calculated, geometries for the compensation measures and their proposed targets are also needed.
