Preservation, Regulations, and Policy to Protect and Grow Baltimore’s Forests.

To further advance the efforts of Baltimore Green Space, Baltimore’s Department of Recreation and Parks, and Baltimore’s Office of Sustainability, a process is underway to propose new regulations that would better protect and mitigate impacts of development on trees and forested natural areas.

Forest Ethnography

An approach to study the environmental history and political ecology of urban forests.

This paper describes a research approach called “forest ethnography,” which we are piloting in Baltimore as part of the Baltimore Ecosystem Study (BES). This urban forest specific approach can contribute to our understanding of both forest environmental history and urban political ecology.

Conceptualizing social-ecological drivers

Urban Ecosystems

Conceptualizing social-ecological drivers of change in urban forest patches

Introducing a conceptual model of the urban forest patch as a complex social-ecological system, incorporating cross-scale interactions.

The Capacity of Urban Forest Patches

The capacity of urban forest patches to infiltrate stormwater is influenced by soil physical properties and soil moisture

Urbanization alters the hydrologic cycle by creating impervious surfaces (e.g. roofs, parking lots, and roads) and compacting soils, reducing watershed infiltration capacity.

Benefits of Urban Community-Managed Open Space

Green spaces can become multi-tasking oases that provide social, economic, and environmental benefits.

Baltimore’s nearly 12,000 vacant lots – 5 percent of all parcels in the city – reduce property residents’ quality of life and depress property values.
