Why is it endangered? Cause cards
Link each protected-species card to its cause cards. The answer is the Korean designation reasons (National Institute of Biological Resources); then compare them with the causes in the world list (IUCN) global assessment. Your choices stay on this screen and are not saved.
How it works and how to give input
Press a species card, then press every cause card you think fits it; press again to remove. With a mouse you can also drag a cause card onto a species card. With a keyboard, move between cards with Tab and choose with Enter or Space. When done, press 'Check answers'. Causes in the record show as 'right', causes you missed as 'missed', and causes not in the record as 'not in the record' — which is not necessarily a wrong idea. Cause names are short labels grouping the threat entries of the source; the source sentences are not reproduced.

Choosing your own or a received deck uses only its species instead of the country, group and grade filters.

Cause cards
Choose a species card first; the cause cards you press then go to that species.

Domestic causes vs global causes
For the same species, the causes named in Korean records and in the world list global assessment can differ. Left: Korean designation reasons; right: the world danger rating.
Only causes with the same name count as 'in both'. Korean labels (for example 'habitat development and destruction') differ from world list scheme names, so causes close in meaning can still appear apart. The world danger rating covers the whole world range; the Korean record describes the situation in Korea.
After you check the answers, a comparison appears below for the species in this round that have a world danger rating.
Step 3 (optional): from causes to actions
Once the causes are known, look at the actions. For each species the Korean designation reasons sit next to the actions already in place and the actions still needed.
The action lists are the conservation-action entries of the world list global assessment (whole world range). Work in Korea is shown separately.
After you check the answers, each species in this round shows its causes and actions side by side.
“translated” marks a machine-translated name.
