Nettle

Model Family : Resident detectability

Summary

Nettle

Resident with summer detectability collapse

Nettle 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 moderate baseline presence, moderate spring carry-over, moderate pre-summer retention, moderate summer suppression, and strong summer decay acceleration.
