Originator:Minnesota DNR - Division of Forestry

Title: Minnesota DNR Old Growth Forest

Abstract: This layer is a digital inventory of individual old growth forest stands. This data originates from the Minnesota DNR's "Forest Inventory Management" system (also referred to as FIM). Old growth designations are determined through an interdisciplinary evaluation process by DNR staff in divisions of Forestry, Fish and Wildlife, Ecological and Water Resources, and Parks and Trails. These data are updated on a continuous basis, as needed.

Purpose: Forest resource planning, harvest plans, treatment plans, wildlife habitat assessment, natural heritage review, native plant community mapping support, historical vegetation studies

Time Period of Content Date: 03/14/2022

Attribute Accuracy:

Logical Consistency: Some non-data polygons are unlabeled.

Completeness: As new lands are acquired, Forest Inventory data collection is scheduled.

Horizontal Positional Accuracy: Features are digitized onscreen over standard 24k DRGs and USGS DOQs and will inherit the horizontal positional accuracy of those products.

Vertical Positional Accuracy: Not Applicable
