Episode Information

Tagus International is a protected natural space shared between Spain and Portugal. Such is its diversity, it’s thought that more animal and plant species live here than in all of many European countries! It’s no wonder the area has been declared the first international natural park in Europe. Separated by the Tagus River, we explore the ecological differences between the Spanish and Portuguese banks of the park, and witness the sight - recorded since ancient times - of animals crossing the great river and mixing with the population found on the opposite bank. Prepare to be amazed and exhilarated by this carnival of nature.
