also known as ecosystem services.
See our short film (4:20) about the conservation of ecosystem services from migratory species. This film focuses on pest-control services provided by Mexican free-tailed bats. These bats overwinter in Mexico and females migrate for the summer months to the southwestern US where they gather in large maternity roosts and consume vast quantities of flying insects every night. This natural pest-control service has supported agriculture in the US/Mexico border region for generations.
