Common Cleavers

Model Family : Resident detectability

Summary

Common Cleavers

Resident with summer detectability collapse

Common Cleavers is classified as resident with summer detectability collapse. The fitted resident detectability target peaks around May and reaches its lowest point around September. The model indicates weak baseline presence, moderate spring carry-over, moderate pre-summer retention, moderate summer suppression, and strong summer decay acceleration.
