What is the consequence of heavy channelization on functionally rare spotted gar populations?

Answer

It severely diminishes ecological connectivity between healthy habitats.

When essential nursery and feeding grounds vanish due to water management or channelization, the connectivity between stable, reproducing groups is lost, making the species functionally rare across the larger watershed even if some local groups persist.
