THE DECISION

Today and tomorrow are broadly similar

The difference is only 5 points (86/100 today, 91/100 tomorrow), so there is no strong conditions-based reason to postpone solely for the forecast. The main forecast change is that maximum wind rises from 5 to 10 mph, and the low changes from 66°F to 55°F.

Most important: Mapped wetland habitat: The surrounding area has a substantial mapped wetland footprint. That supports habitat context, but it does not prove birds are present today.

INTERPRETATION

What the numbers actually change

Good

Mapped wetland habitat

6,668 acres within 10 mi

The surrounding area has a substantial mapped wetland footprint. That supports habitat context, but it does not prove birds are present today.

Context

Wind / field setup

5 mph max

Very light wind may make some setups feel static, but this does not predict migration.

 Grasslands Wildlife Management Area (WMA) was established in 1979 and is located in western Merced County, California within the San Joaquin River basin. Unlike typical national wildlife refuges, Grasslands WMA is comprised mostly of privately-owned lands on which perpetual conservation easements for the benefit of wildlife have been established between landowners and the U.S. Fish and Wildlife Service. These easements preserve wetland and grassland habitats for wildlife, as well as some wildlife-friendly agricultural lands. The…

Official directions: The public is not permitted on the Grasslands Wildlife Management Area, as the Service did not acquire public use rights. It can be viewed from adjacent public roads, primarily Santa Fe Grade Road, which bisects the north and south Grasslands in a northwest-southeast direction, north and south of Los Banos.

6,668 mapped wetland acres were returned within the 10-mile query area.

WHAT THIS PAGE DOESN'T KNOW YET

Important gaps

  • Regional snow/freeze progression, crop/food context and live bird observations are not yet part of this score; do not treat it as a migration forecast.
