The Risks and Consequences of Catastrophic Wildfires on the Conifer Forests of the Sierra Nevada of California

Forests in California’s Sierra Nevada have become increasingly vulnerable to wildfires due to fire suppression practices, elevated tree mortality and warming temperatures. With these fires growing in severity, these forests are struggling to recover on their own, creating landscapes that are more susceptible to future fires and increased forest loss. Researchers supported by this...

Late Holocene human-environment interactions on the central California coast, USA, inferred from Morro Bay salt marsh sediments Late Holocene human-environment interactions on the central California coast, USA, inferred from Morro Bay salt marsh sediments

Coastal salt marshes and estuaries provide valuable ecosystem services, yet are susceptible to alteration from human activities. Records of past environmental change in these ecosystems can elucidate relationships between human activities, such as land-use practices, and physical and ecological processes, such as sediment accretion and vegetation changes. To reconstruct the environmental...
