Species Presence

Index values ranging from 0 (no indicator species group) to 100 (intact)

Provides information on the occurrence of plant and animal species within a specific geographic area. This data can be derived from direct observations or predictive models and is fundamental for biodiversity assessment. It is used to identify areas of high conservation value, monitor for invasive species, and assess the potential impacts of land use change on wildlife.

For each project, land stewards select species from a pre-approved list covering ten indicator species groups, aiming to confirm the presence of all groups. Observations must include the species name, location, timestamp, and supporting evidence such as photos, videos, acoustic recordings, or track data. These can be based on direct sightings or indirect signs like tracks, dung, or scratch marks. Indicator species scores are calculated by mapping species presence with buffers around observations. Confidence scores decrease over time and distance from the original sighting. Each species group is assigned a score from 0 (not detected) to 10 (all groups detected). These scores are then summed, normalized, and averaged to produce a final confidence score ranging from 0 to 100.
