Extratropical cyclones are large storm systems that form between 30° and 60° latitude. Driven by contrasts between warm and cold air masses, they are responsible for many of the major weather events that affect the United States. #geography www.geographyrealm.com/extratropica...

At Bear Creek Redwoods Open Space Preserve, repeated nesting-season projects by Midpeninsula Regional Open Space District are reshaping habitat used by migratory birds. #MigratoryBirds #HabitatLoss #geography www.geographyrealm.com/midpen-open-...

Microforest projects use the Miyawaki method fast-track the growth of dense, biodiverse forests, aiming to achieve full growth in 20-30 years.

Geography Realm examines the gap between the ecological messaging promoted by an open space agency and its management practices during nesting season. Spring mowing can affect nesting birds and pollinators by removing essential habitat during one of the most biologically active periods of the year.
