Document Summary

Focus on identifying countries rich in species or habitats. Conservation biologists have focused on saving species by the use of four strategies: megadiversity countries, focus efforts here b/c most diverse, 17 countries have 80% of all known species (large countries like usa and small like peru, Ecuador: drawbacks: some overlap i. e. peru and ecuador peru contains 344 mammal species, ecuador. Not a one size fits all strategy: the megadiversity country approach does not incorporate vulnerability as a criteria and emphasizes only high irreplaceability, hence its position in parentheses.
