The Species Protection Index (SPI) measures how much suitable habitat for single species is under protection and estimates the regional or global biodiversity representativeness of terrestrial protected areas.

Purpose

To provide an annually updated, remote-sensing informated, spatially explicit, and global metric of how well terrestrial species are represented in terrestrial protected areas. The Species Protection Index capitalizes on detailed remote sensing data, a global biodiversity informatics infrastructure and integrative models. It is designed to measure and report progress in relation to CBD Aichi Target 11.

CBD Aichi Target 11
Protected Areas
Coverage

The index uses environmental and species data addressing all terrestrial areas of the world at 1km spatial resolution. It can be aggregated at spatial levels ranging from 1km to small regions, countries, biomes, and the whole planet. The index uses land cover information available annually from Landsat and MODIS satellites since 2001 onwards. With continuation of these remote sensing products, this enables annual index updates, including reporting Aichi Target 11 achievements, for ten data points from 2011 to 2020.

Methods

Indicators addressing Aichi Target 11 are typically constrained in their adequate geographic representation, the level of disaggregation they allow, their temporal resolution, and their scientific underpinning and transparency. The Species Protection Index is part of a new generation of indicators that utilize ongoing, spatially and temporally highly resolved remote sensing at near global-extent, together with biodiversity observations and adequate modeling frameworks, to help address these limitations.

The Species Protection Index builds on detailed, remote-sensing informed species distributions and their overlap with protected areas. These species maps are modeled using literature- and expert-based data on habitat restrictions and published land-cover products from MODIS and Landsat satellites available annually at 30m and 1km resolution and validated with field data on species locations from surveys and citizen science. Modifications in the area of individual species’ overall distribution and the proportion under protection are quantfied and updated annually based on changes in protected areas and available
suitable habitat. The index represents the aggregate of species-level metrics over any specified spatial unit such as countries or biomes. It can be calculated for different minimum sizes or categories of protected areas and be separated by biological group. A version of the index can also account for countries’ stewardship of species (their portion of a species’ global range, according to the best-available estimate).

All underlying data and metrics are available through a dedicated dashboard in the Map of Life web interface that has been developed with Google Earth Engine as technology partner. Currently, the Species Protection Index is addressing all protected areas of the World Database on Protected Areas and is calculated for >30,000 species of terrestrial vertebrates and invertebrates, and plant species, and validated with > 350 million location records. This list is growing rapidly as more species and data are entering the database.
