Marylands Strategic Forest Lands Assessment Forest Lands of Economic Importance Allegheny SAF 2002 Winter Meeting February 27, 2002 Maryland Department of Natural Resources
Identify Strategic Forest Lands, or those parts of the state where forest conservation and stewardship efforts would make the greatest contribution toward achieving a sustainable (ecologically and economically) forest resource land base. Marylands Strategic Forest Lands Assessment
Strategic Forests Assessment Components Ecological Assessment Socioeconomic Assessment Vulnerability Assessment Programmatic Assessment Integration with other Efforts Strategic Forests Identification
Socioeconomic Assessment GIS Based Approach to quantifying … l Population Density: Influences on forest management l Parcelization l Local Economic Importance l Forest Ownership (public vs. private) l Water Supply Watersheds l Sourcing or Procurement Zones l Forest Products Operators Economically Important Forest Lands
Socioeconomic Influences on Forest Management Objectives Forest Management Objectives Wildlife HabitatForest Products Soil, Water and Air QualityRecreation TemperatureAesthetics/Quality of Life Management Objectives differ in response to many factors l Sustainable Commercial Forestry and Land Uses l Urban Forests:Less likely: smaller parcels, less tolerant (noise, view, safety) l Rural Forests: More likely: larger parcels, more direct economic ties to forest resource-based economy

Parcelization of private land
Forest Land parcelization
Is the fifth largest industry in the state. Generates over 2.2 billion dollars annually. Supplies over 14,500 jobs statewide. Creates three (3) jobs are elsewhere in the economy for every job in the forestry and wood products industry. Local Economic Importance The Forestry and Wood Products Industry…
The Forestry and Wood Products Industry Timber Management and Harvesting Operation of timber tracts, tree farms and nurseries Reforestation services Harvesting and transporting logs Primary Wood Manufacturing Processing logs into lumber, veneer, plywood, pulp and other products (Mills) Secondary Wood Manufacturing Remanufacture of primary manufacturers products into finished products Examples include furniture, toys, containers, etc.
