BIODIVERSITY OF TROPICAL ECOSYSTEMS IN COSTA RICA

DATA PRODUCTION

Climate impact indicators
Global essential climate variables/indicators used

Precipitation and Temperature are used for calculation of the Holdridge Life Zones. For calculation of the land-use based biodiversity indicators we stick to a protocol used by GIZ/SINAC.

Regional/local indicators used and produced

Basic downscaled and adjusted climatologies of monthly precipitation and temperature with climate change projections will be at local scale. The ecological indictors based on land-use (fragmentation, % land use change) will be linked to calculated Holdridge Life Zones and a species inventory. Projections of the Holdridge Life Zones can then provide information on future scenarios of how species associated to the life zones potentially move.

Quality control will be done through periodic meetings (2-3 months) monitoring the production of results in combination with local data that are incorporated into the workflow. Because of Costa Ricas relatively sparse monitoring network, basic indicators like temperature and precipitation can already provide add significant value to locally calculated results.

Global data to regional/local scale

Step 1: Produce precipitation and temperature climatologies purely based on local station data (annual and monthly)

Step 2: Calculate land use-based biodiversity indicators for the national biocorridor program of our partners

Step 3: Calculate updated national Holdridge life zone biodiversity indicators with potential link to species distribution based on the local climatologies generated under step 1

Step 4: Merge land use-based biodiversity indicators on a national scale with updated Holdridge life zones

Step 5: Downscale and bias-correct global climate data for Costa Rica (CMIP ensemble bias-corrected to HydroGFD at 50 km grid scale) to national data product created in Step 1. Project the merged biodiversity indicator(s) into climate change impact period.
