Biodiversity records accessible through GBIF
This indicator reflects the status and trends of shared biodiversity knowledge as measured through the number of species occurrence records published through the Global Biodiversity Information Facility (GBIF). The values represent the number of records (i.e., unique instances of a species being recorded in space and time) published by local institutions for countries or regions in 2007-2016. The average annual change rate of the species occurrence records was calculated over the last five years (2011-2016).
By 2020, knowledge, the science base and technologies relating to biodiversity, its values, functioning, status and trends, and the consequences of its loss, are improved, widely shared and transferred, and applied.
The number of species occurrence records published through GBIF documents the amount of basic biodiversity data that are freely discoverable and accessible by researchers and policymakers via the internet. A greater availability of records indicates greater levels of knowledge and sharing of biodiversity information. A decline would indicate that data holders were withdrawing datasets from public access, reducing the availability of such data for research and policy, or removing duplicate records.
The average annual change rate of the species occurrence records ranges from zero up, with higher values representing quicker increases in the volume of records.
This indicator is available globally at the country and CBD/WDPA-regional scales.
The average annual change rate of species occurrence records is available over the last five years from 2011 to 2016.
The annual number of species occurrence records is available for the years 2007-2016 as baselines.
GBIF hosts the largest biodiversity database portal on the internet, exposing data shared by hundreds of institutions worldwide. Funded by governments, through collaboration between its Participant nodes of countries and organizations, and the secretariat, the Global Biodiversity Information Facility (GBIF) serves as an international open data infrastructure by helping institutions to publish data according to common standards and allowing anyone, anywhere to access data about all types of life on earth, shared across national boundaries via the internet. The GBIF provides a single point of access to hundreds of millions of records.
GBIF produces trend charts on data mobilized by GBIF network from the end of 2007 until recent weeks and update them periodically, approximate quarterly. These charts are available to view by country through GBIF National data trends.
We acquired the record data for all the country, territories and islands available to date (most recently, August 15, 2016), smoothed the temporal trend by taking the last counts of species occurrence record in each year, and generated the GBIF biodiversity records indicator with yearly intervals for each country that has data available. For each country, the average annual change rate was calculated over the entire time period from the first year when the species occurrence records were available to 2016, as well as over the time period of last 5 years (i.e., 2011-2016). The map visualization shows the average annual change rate over the last 5 years to make countries data comparable. The chart visualization enabled by clicking a country shows the yearly data and change rate during both time frames.
We further grouped country data according to CBD/WDPA regions, and calculated the GBIF biodiversity records indicator at regional scales as well.
NatureServe re-analyzed the source data to calculate trends and aggregated the data to generate the regional spatial scale.
This indicator was generated using the GBIF publishing trend showing the volumes of records published by institutions located in the country or region, i.e., information from institutions in countries or regions where specimens or observations of species originate. GBIF releases another metric, the GBIF trend about, showing the number of records that originated in a particular country regardless of the location of the institution providing the records.
GBIF participant countries and organizations joined the network in varies times; therefore, the year when the indicator started having data varies among countries. We calculated the annual change rate for both the entire time period when records were available for each country as well as over the last five years. To allow for comparisons across countries and regions, the map visualization shows the average annual change rate over the last five years (a period for which data are available for most countries). Users can find the yearly data and change rates calculated for both time frames in the chart visualization, which can be enabled by clicking a country on the map.
A few territories and islands were grouped with corresponding countries to be consistent with other Dashboard indicator locations.
