Many voices. Greener cities. Better cities.

UBHub arose as a response to gaps and bottlenecks in urban biodiversity planning and management. Developed with practitioners in mind, its goals are increasing capacity of local governments and their partners to develop knowledge-driven biodiversity strategies
Cities that plan for biodiversity recognize the potential of healthy ecosystems to mitigate urban problems and enhance quality of life but, due to limited capacity, can struggle with developing and managing their biodiversity strategies. Our team at the Urban Biodiversity Hub (UBHub) has compiled thousands of examples of biodiversity work from local governments and environmental NGOs around the world that can help. After two years of development, we have now publicly launched the largest public database of urban biodiversity activities worldwide. Our database is a one-stop shop that makes it easier for people to explore urban biodiversity practices and select from helpful resources.

In defining the scope of the database, we use a broad definition of urban biodiversity that encompasses all activities and information related to urban nature and the influence of cities on conservation, including individual species plans, green and blue infrastructure, impact on regional landscapes and global conservation goals, environmental education, and more. Together, these data consolidate information previously scattered across hundreds of sites into one searchable location.

The UBHub database has two parts, now available and free to explore at (1) an interactive map of biodiversity in practice, consisting of plans, reports and activities, and (2) a resource guide that organizes and compares tools for urban biodiversity.

About the map

The UBHub map visualizes global and regional patterns of what cities and other actors are doing to improve local biodiversity. Each of the map’s 1,200+ markers (as of October 2018) contains a list of urban biodiversity activities, documents, programs, and awards related to that location, along with links to the original sources. The data can also be filtered by city parameters to locate comparable biodiversity efforts. Markers on the map can be searched by keyword and can be highlighted by program or filtered according to several variables, including scale, population, density, biome, and conservation status. The map database is also available in a summary or in table form.

The data available via the map are already proving useful for practitioners and researchers. Staff at the City of Los Angeles, in preparation for creating their own biodiversity strategy, used the UBHub map to locate other municipalities that have instituted specific programs and activities of interest.  Researchers have used the database to quickly locate government documents and summarize current practices in urban biodiversity. Our team also harnessed the database to put together a summary report of current practice as contributors to The Nature Conservancy’s Nature in the Urban Century assessment (McDonald et al. 2018).

Of the variety of document types (reports, plans, declarations, maps, etc.) in our database, the most comprehensive data so far are on municipal biodiversity reports and plans. We have identified at least 123 cities from 31 countries that have produced a biodiversity report and/or a biodiversity plan; 108 of these have published biodiversity plans, 46 have published biodiversity reports, and 31 have published both. Cities around the world have taken part, although the majority of documents were produced by cities in Europe, followed by North America and then Asia. Cities of all sizes are planning for biodiversity, from towns with populations of less than 100,000, such as Curridabat, Costa Rica, to megacities such as Shanghai, China.

A biodiversity plan is an official government document that indicates the intended strategy for biodiversity conservation. A biodiversity report is a document that summarizes the current conditions of biodiversity within a particular area. Data are based on the public database at and originally produced for McDonald et al. (2018).

Another comprehensive data set is a compilation of municipal participants in biodiversity programs. Programs help cities manage or plan for biodiversity by offering a standardized index or series of steps that sometimes comes with institutional support. Examples of such programs include the Singapore Index (also known as the City Biodiversity Index or Singapore Index on Cities’ Biodiversity), the Ecological Footprint, the Biophilic Cities Network and other international programs. We mapped municipal participants in 26 frameworks and programs that are specific to urban biodiversity and are in use in more than one country.

About the guide

In addition to the map, the UBHub website also includes a guide, which is a collection of resources that are useful for urban biodiversity practitioners. The resources are organized by category and linked back to the original source. Categories include public engagement, regulations, data repositories, conferences, measurement tools, blogs, and more.

One feature of the guide is a program comparison to help practitioners make an informed decision about their biodiversity approach by comparing nine systems at once. The comparison includes a basic description of each program, the program steps, participation requirements, and the pros and cons of each. This comparison can help a city more efficiently select a program that is right for them. Practitioners often have little time to research comparable efforts in other cities or compare approaches, and may end up either developing a system on their own or adopting a pre-existing framework without having the opportunity to analyze or even find out about alternatives. With the many numerous urban biodiversity strategies and programs being applied around the globe, it is difficult to discover and select an appropriate program. We hope that this comparison will help practitioners identify the most suitableprogram for their city or community.


We recognize that capacity and needs vary from region to region and city to city, and that knowledge of urban biodiversity and related topics is spread around the world. We therefore believe that an international exchange of knowledge and resources can bring important insights and offer opportunities for future collaboration. To that end, the UBHub website also includes a dedicated discussion forum accessible to logged-in users. On the forum, users can post or respond to questions and vote up or down on content to ensure quality. Positive votes on a user’s contributions add to the user’s reputation points in recognition of their contribution to the dialogue.

Future plans

We are now developing the myIndicators web platform for cities and their partner organizations to select and manage biodiversity indicators. City representatives will be able to log in, connect to the dashboard for their city, invite collaborators to join their dashboard, select their indicators, and start managing their biodiversity strategy. They may choose from several pre-existing index programs or create their own custom set of indicators. Indicators can include quantitative trends such as the amount of tree canopy cover or number of participants in education programs, or qualitative steps such as approval of a biodiversity plan by city council. The myIndicators dashboard will provide practitioners with a summary of their city’s progress and downloadable reports to use and share. It will also link to the forum, where practitioners can connect with researchers and one another to compare approaches and share techniques.

We are working with several cities and NGOs in our beta testing program to refine the myIndicators platform over the upcoming years. These beta testers are leaders in the field of urban biodiversity and pioneers in the measurement and management of urban biodiversity indicators. Ultimately, the myIndicators platform will help cities and communities manage their indicators, track their data, generate reports, and improve the efficiency and effectiveness of their biodiversity planning and management.

Collectively, UBHub’s components—the map, guide, forum, and myIndicators—arose as a response to the gaps and bottlenecks in urban biodiversity planning and management. While developing UBHub, we spoke with many researchers and practitioners who told us that urban biodiversity is generally championed by one or a few passionate staff members who take on the city’s biodiversity or conservation-related efforts on top of other responsibilities. We developed UBHub’s components with these practitioners in mind, with the goals ofincreasing the capacity of local governments and their partners to develop biodiversity strategies and of making urban biodiversity resources more widely available.

As we move forward in partnership with our beta test cities in developing myIndicators and other tools, we invite interested parties to join us in promoting the value of urban biodiversity and facilitating better urban biodiversity management by adding and using data, as a volunteer, or as an organizational partner.
