Migratory species* play a vital role in pollination and maintaining woodlands. Thank you for pointing out the correction.
They are an important part of ecosystems, often shaping how ecosystems function. (You may have learned about bottom up and top down regulation in schools, they affect that) and the less of them that remain, the less resilient areas become to disruption. They also affect nutrient cycling, bringing themselves in and out of systems.
