This geospatial dataset depicts ownership patterns of forest land across Michigan, circa 2019. The data sources are listed below. The first seven sources of data supersede the final data source. The final data source is modeled from Forest Inventory and Analysis points from 2012-2017 and the most up-to-date publicly available boundaries of federal, state, and tribal lands.1.MI_State_Boundary_Census_Gov_2019.shp (State of MI boundary) clipped from cb_2019_us_state_500k from https://www.census.gov/geographies/mapping-files/time-series/geo/cartographic-boundary.html2.NPS_Land_Resources_Division_MI.shp clipped from NPS_-_Land_Resources_Division_Boundary_and_Tract_Data_Service-shp taken from https://public-nps.opendata.arcgis.com/datasets/nps-land-resources-division-boundary-and-tract-data-service/data?layer=1Published December 12, 2019This service depicts National Park Service tract and boundary data that was created by the Land Resources Division. NPS Director's Order #25 states: "Land status maps will be prepared to identify the ownership of the lands within the authorized boundaries of the park unit. These maps, showing ownership and acreage, are the 'official record' of the acreage of Federal and non-federal lands within the park boundaries. While these maps are the official record of the lands and acreage within the unit's authorized boundaries, they are not of survey quality and not intended to be used for survey purposes." As such this data is intended for use as a tool for GIS analysis. It is in no way intended for engineering or legal purposes. The data accuracy is checked against best available sources which may be dated and vary by location. NPS assumes no liability for use of this data. The boundary polygons represent the current legislated boundary of a given NPS unit. NPS does not necessarily have full fee ownership or hold another interest (easement, right of way, etc...) in all parcels contained within this boundary. Equivalently NPS may own or have an interest in parcels outside the legislated boundary of a given unit. In order to obtain complete information about current NPS interests both inside and outside a unit’s legislated boundary tract level polygons are also created by NPS Land Resources Division and should be used in conjunction with this boundary data.

Forest type group layer was developed using data from over 213,000 national forest inventory plots measured during the period 2014-2018 from the USDA Forest Service Forest Inventory and Analysis (FIA) program, in conjunction with other auxiliary information. Roughly 4,900 Landsat 8 Operational Land Imager scenes, collected during the same time period, were processed to extract information about vegetation phenology. This information, along with climatic and topographic raster data, were used in an ecological ordination model of tree species. The model produced a feature space of ecological gradients that was then used to impute FIA plots to pixels. The plots imputed to each pixel were then used to assign values of forest type groups.

In this project we established a network of forest inventory plots to gather the data needed to forecast future forest performance under global change. Data collected from forest inventory plots, i.e., size and location of individual trees from all ages and species, have been shown to be particularly useful to link tree species demographic rates (survival, growth, age at maturity, fecundity) with community characteristics (assemblages and species turnovers), and are also widely used to estimate biomass removal (logging) and biomass production (carbon sequestration).

A stand is a polygon representing a relatively homogenous area of similar cover type. Stands are classified as ‘forested’ (having a canopy of tree species greater than 3 feet tall covering at least 25% of the stand area) or ‘nonforested’ (all stands not meeting the definition of forested). In forested stands, the age class of trees, species composition, basal area stocking, and age structure will be consistent. Nonforested stands are areas of similar species composition.

Stands follow mapping standards per MiFI Manual.

Recent and previous disturbance of forest canopy, persisting forest cover, persisting nonforest, and water were mapped within Lake Michigan basin, USA, 1985-2008. Landsat time series stacks and a regionally optimized vegetation change tracker algorithm were used for modeling a 30-meter spatial resolution dataset with a minimum mapping unit of 4 pixels (0.88 acres).The dataset was designed and produced to support Great Lakes Restoration Initiative (GLRI) assessments of water quality. Possible additional purposes include, but are not limited to: monitoring areal forest change across time, forest succession monitoring, forest fragmentation monitoring, and land management planning at a scale of 1:24000 scale or coarser.A corresponding Research Map cartographically portrays this dataset. A companion dataset and map have been produced for Lake Superior basin, USA and Canada. See references below.

Original metadata date was 08/01/2014. Minor metadata updates on 12/13/2016 and 10/03/2019.

These geospatial data portray early successional forest (ESF) and other land cover in Michigan, Wisconsin, and most of Minnesota. Forest canopy disturbance between 1990 and 2009 was mapped using 42 Landsat time series stacks (LTSS) and a modified version of the vegetation change tracker algorithm (VCTw). Corresponding winter imagery was used to reduce commission errors of forest disturbance in densely vegetated nonforest tracts by identifying areas of persistent snow cover and assigning those areas to nonforest class. The resulting disturbance age map was classed into four 5-year age classes and persisting cover classes, then used to attribute age to forested pixels within the National Land Cover Database of 2011 (NLCD2011). Additional post processing was conducted to reduce misregistration, and a minimum mapping unit of 4 30-meter pixels was applied to comply with the USDA Forest Service, Forest Inventory and Analysis (FIA) definition of forest. A small percentage of NLCD2011 Shrub/Scrub and Grassland/Herbaceous pixels were also reclassified as forest based on VCTw data (see processing steps).These data were produced to identify early successional forest for wildlife habitat analyses at a regional scale. Other possible uses include coarse scale analysis of regional or statewide forest change and succession monitoring, erosion and water quality modeling, carbon accounting, forest fragmentation monitoring, and land management planning.Original metadata dates was 01/14/2016. On 04/07/2016 the layer file was slightly modified by updating a path which now points to a relative location so that it works for all users, and the metadata updated accordingly.

The purpose of "Ecological Diversity of the Huron-Manistee National Forests" is to determine the ecological diversity of the Huron-Manistee National Forests of northern Lower Michigan by determining the occurence of landscape ecosystems at several hierachical spatial scales to determine the major wetland ecosystems, provide examples of local wetland ecosystems, and map their pattern of occurence to determine how well the areas designated as potential old growth forests represent the ecological diversity of the forests, and to provide and overall conceptual model for the study of ecological diversity of large landscapes.

The overall goal is to characterize the ecological diversity of the Huron-Manistee National Forest, an area of over 800,000 acres in the northern part of lower Michigan. In particular, to examine the extent to which the 173,000 acres of old-growth lands tentatively set aside respresent the full range of ecological diversity.

Collection Organization: University of Michigan, School of Natural Resources & Environment

Collection Methodology: The approach is to study the existing regional and local classifications of the area and determine kinds and patterns of landscape ecosystems within selected levels of these classifications, to determine the amount of old growth forest in each classification unit and unique ecosystems that should be set aside as old growth, to examine and sample dryland and wetland ecosystems throughout the forests and develop a classification of wetland ecosystems for the area, map local areas to illustrate the fine-scale diversity of landscape ecosystems. In the field transects were run and sampled, and sample plots were established and sampled.

Collection Frequency: Data collected at different places in field seasons: 1992, 1993, 1994.

Update Characteristics: No data update. Analyses have been performed on field data.

Type of Road Proposals

Open to ORVs

Roads recommended to be opened to ORV use. Proposals in this category may include roads added because of new construction or because an existing road was missed in the initial inventory. Other proposals in this category include roads that were previously closed to ORV use, but due to a change in circumstances or public input, are recommended to be opened to ORV use.

Closed to ORVs

Roads recommended to be closed to ORV use. Proposals in this category may include newly constructed roads, roads missed in the initial inventory process or roads that were previously open and are now recommended for closure. A recommendation to close roads to ORVs could be for natural resource protection or because of user conflicts.

Closed to All Vehicles

Roads recommended to be closed to all conventional vehicles and ORVs. Proposals in this category may include roads that were previously either open or closed to ORV use and were open to use by conventional vehicles. Closure recommendations could be made due to natural resource damage, for example.

Data Cleanup

Roads recommended to be deleted and removed from the statewide forest road inventory. Proposals in this category include roads that may appear on published DNR forest road maps that no longer exist on the ground. Other proposals in this category include roads that are duplicates of an already existing road that need to be removed. Data cleanup is part of an ongoing effort to ensure accurate forest road maps.

This dataset combines the work of several different projects to create a seamless data set for the contiguous United States. Data from four regional Gap Analysis Projects and the LANDFIRE project were combined to make this dataset. In the northwestern United States (Idaho, Oregon, Montana, Washington and Wyoming) data in this map came from the Northwest Gap Analysis Project. In the southwestern United States (Colorado, Arizona, Nevada, New Mexico, and Utah) data used in this map came from the Southwest Gap Analysis Project. The data for Alabama, Florida, Georgia, Kentucky, North Carolina, South Carolina, Mississippi, Tennessee, and Virginia came from the Southeast Gap Analysis Project and the California data was generated by the updated California Gap land cover project. The Hawaii Gap Analysis project provided the data for Hawaii. In areas of the county (central U.S., Northeast, Alaska) that have not yet been covered by a regional Gap Analysis Project, data from the Landfire project was used. Similarities in the methods used by these projects made possible the combining of the data they derived into one seamless coverage. They all used multi-season satellite imagery (Landsat ETM+) from 1999-2001 in conjunction with digital elevation model (DEM) derived datasets (e.g. elevation, landform) to model natural and semi-natural vegetation. Vegetation classes were drawn from NatureServe's Ecological System Classification (Comer et al. 2003) or classes developed by the Hawaii Gap project. Additionally, all of the projects included land use classes that were employed to describe areas where natural vegetation has been altered. In many areas of the country these classes were derived from the National Land Cover Dataset (NLCD). For the majority of classes and, in most areas of the country, a decision tree classifier was used to discriminate ecological system types. In some areas of the country, more manual techniques were used to discriminate small patch systems and systems not distinguishable through topography. The data contains multiple levels of thematic detail. At the most detailed level natural vegetation is represented by NatureServe's Ecological System classification (or in Hawaii the Hawaii GAP classification). These most detailed classifications have been crosswalked to the five highest levels of the National Vegetation Classification (NVC), Class, Subclass, Formation, Division and Macrogroup. This crosswalk allows users to display and analyze the data at different levels of thematic resolution. Developed areas, or areas dominated by introduced species, timber harvest, or water are represented by other classes, collectively refered to as land use classes; these land use classes occur at each of the thematic levels. Raster data in both ArcGIS Grid and ERDAS Imagine format is available for download at http://gis1.usgs.gov/csas/gap/viewer/land_cover/Map.aspx Six layer files are included in the download packages to assist the user in displaying the data at each of the Thematic levels in ArcGIS. In adition to the raster datasets the data is available in Web Mapping Services (WMS) format for each of the six NVC classification levels (Class, Subclass, Formation, Division, Macrogroup, Ecological System) at the following links. http://gis1.usgs.gov/arcgis/rest/services/gap/GAP_Land_Cover_NVC_Class_Landuse/MapServer http://gis1.usgs.gov/arcgis/rest/services/gap/GAP_Land_Cover_NVC_Subclass_Landuse/MapServer http://gis1.usgs.gov/arcgis/rest/services/gap/GAP_Land_Cover_NVC_Formation_Landuse/MapServer http://gis1.usgs.gov/arcgis/rest/services/gap/GAP_Land_Cover_NVC_Division_Landuse/MapServer http://gis1.usgs.gov/arcgis/rest/services/gap/GAP_Land_Cover_NVC_Macrogroup_Landuse/MapServer http://gis1.usgs.gov/arcgis/rest/services/gap/GAP_Land_Cover_Ecological_Systems_Landuse/MapServer

Vegetation field plots at Isle Royale National Park were visited, described, and documented in a digital database. The database consists of 2 parts - (1) Physical Descriptive Data and (2) Species Listings.

The vegetation plots were used to describe the vegetation in and around Wind Cave National Park and to assist in developing a final mapping classification system.

The purpose of the vegetation plots was to provide National Parks with the necessary tools to effectively manage their natural resources. Plot data are collected and analyzed to develop a classification (using the Standardized National Vegetation Classification System) and description of vegetation types in preparation for photointerpretation and mapping of the Park's vegetation types.

Isle Royale National Park was authorized on March 3, 1931; it was formally established in 1940, and officially dedicated in 1946. Most of the park's land area (98%) was designated as a Wilderness area in October 1976, and later additions increased the total Wilderness to 99% of the park. The park was designated an International Biosphere Reserve in 1980.

Field sampling was performed using releve plots.

This data set provides a land use/land cover map of the Ji-Parana River Basin in the state of Rondonia, Brazil produced from the digital classification of eight Landsat 7-ETM+ scenes from 1999 acquired from the Tropical Rain Forest Information Center (TRFIC) at Michigan State University. Nine land cover classes covering the Ji-Parana Basin were identified. There is one GeoTiff file with this data set.

This data set includes parcel boundaries as delineated by the DNR Forest Resources Division, Resource Assessment Section, on behalf of the Commercial Forest Program.More than 2.2 million acres of private lands enrolled in the Commercial Forest Program are open to public foot traffic for hunting, trapping and fishing. Any other activities require landowner permission. Respect these lands and private landowners. Commercial Forest lands are not posted or signed as commercial forests and may be fenced and/or gated. The presence of a fence or gate does not prohibit public access by foot to these lands for fishing or hunting. The owner may restrict public access during periods of logging to ensure public safety.For more information visit the DNR Commercial Forest Program

The National Park Service (NPS), in conjunction with the Biological Resources Division (BRD) of the U.S. Geological Survey (USGS), has implemented a program to "develop a uniform hierarchical vegetation methodology" at a national level. The program will also create a geographic information system (GIS) database for the parks under its management. The purpose of the data is to document the state of vegetation within the NPS service area during the 1990's, thereby providing a baseline study for further analysis at the Regional or Service-wide level. The vegetation units of this map were determined through stereoscopic interpretation of aerial photographs supported by field sampling and ecological analysis. The vegetation boundaries were identified on the photographs by means of the photographic signatures and collateral information on slope, hydrology, geography, and vegetation in accordance with the Standardized National Vegetation Classification System (October 1995). The mapped vegetation reflects conditions that existed during the specific year and season that the aerial photographs were taken (spring - 1996 and fall - 1994). There is an inherent margin of error in the use of aerial photography for vegetation delineation and classification.

The purpose of this spatial data is to provide the National Park Service the necessary tools to wisely manage the natural resources within this park system. Several parks, representing different regions, environmental conditions, and vegetation types, were chosen by BRD to be part of the prototype phase of the program. The initial goal of the prototype phase is to "develop, test, refine, and finalize the standards and protocols" to be used during the production phase of the project. This includes the development of a standardized vegetation classification system for each park and the establishment of photointerpretation, field, and accuracy assessment procedures. Isle Royale National Park was initially identified as one of the prototypes within the National Park System for the USGS-NPS Vegetation Mapping Program. Isle Royale National Park was established March 3, 1931 and was also designated as an International Biosphere Reserve in 1980. The park contains approximately 571,790 acres of land and water (893 square miles) of which 133,782 acres is land and the rest is open water of Lake Superior as well as inland lakes and ponds. Isle Royale National Park is an archipelago of islands located in the northwestern region of Lake Superior close to the United States-Canada border. The main island, Isle Royale, consists of a series of ridges and valleys running the length of the island and is surrounded by approximately 200 smaller islands. The primary methods of transportation on the island are hiking and boating. Isle Royale National Park was authorized on March 3, 1931; it was formally established in 1940, and officially dedicated in 1946. Most of the park's land area (98%) was designated as a Wilderness area in October 1976, and later additions increased the total Wilderness to 99% of the park. The park was designated an International Biosphere Reserve in 1980.

Isle Royale National Park is an archipelago of islands located in the northwestern region of Lake Superior close to the United States-Canada border. The park is located about 60 miles northwest of Michigan.s Keweenaw Peninsula, about 22 miles east of Grand Portage, Minnesota, and about 35 miles southeast of Thunder Bay, Ontario.

The USGS Protected Areas Database of the United States (PAD-US) is the nation's inventory of protected areas, including public open space and voluntarily provided, private protected areas, identified as an A-16 National Geospatial Data Asset in the Cadastral Theme (http://www.fgdc.gov/ngda-reports/NGDA_Datasets.html). PAD-US is an ongoing project with several published versions of a spatial database of areas dedicated to the preservation of biological diversity, and other natural, recreational or cultural uses, managed for these purposes through legal or other effective means. The geodatabase maps and describes public open space and other protected areas. Most areas are public lands owned in fee; however, long-term easements, leases, and agreements or administrative designations documented in agency management plans may be included. The PAD-US database strives to be a complete “best available” inventory of protected areas (lands and waters) including data provided by managing agencies and organizations. The dataset is built in collaboration with several partners and data providers (http://gapanalysis.usgs.gov/padus/stewards/). See Supplemental Information Section of this metadata record for more information on partnerships and links to major partner organizations. As this dataset is a compilation of many data sets; data completeness, accuracy, and scale may vary. Federal and state data are generally complete, while local government and private protected area coverage is about 50% complete, and depends on data management capacity in the state. For completeness estimates by state: http://www.protectedlands.net/partners. As the federal and state data are reasonably complete; focus is shifting to completing the inventory of local gov and voluntarily provided, private protected areas. The PAD-US geodatabase contains over twenty-five attributes and four feature classes to support data management, queries, web mapping services and analyses: Marine Protected Areas (MPA), Fee, Easements and Combined. The data contained in the MPA Feature class are provided directly by the National Oceanic and Atmospheric Administration (NOAA) Marine Protected Areas Center (MPA, http://marineprotectedareas.noaa.gov ) tracking the National Marine Protected Areas System. The Easements feature class contains data provided directly from the National Conservation Easement Database (NCED, http://conservationeasement.us ) The MPA and Easement feature classes contain some attributes unique to the sole source databases tracking them (e.g. Easement Holder Name from NCED, Protection Level from NOAA MPA Inventory). The "Combined" feature class integrates all fee, easement and MPA features as the best available national inventory of protected areas in the standard PAD-US framework. In addition to geographic boundaries, PAD-US describes the protection mechanism category (e.g. fee, easement, designation, other), owner and managing agency, designation type, unit name, area, public access and state name in a suite of standardized fields. An informative set of references (i.e. Aggregator Source, GIS Source, GIS Source Date) and "local" or source data fields provide a transparent link between standardized PAD-US fields and information from authoritative data sources. The areas in PAD-US are also assigned conservation measures that assess management intent to permanently protect biological diversity: the nationally relevant "GAP Status Code" and global "IUCN Category" standard. A wealth of attributes facilitates a wide variety of data analyses and creates a context for data to be used at local, regional, state, national and international scales. More information about specific updates and changes to this PAD-US version can be found in the Data Quality Information section of this metadata record as well as on the PAD-US website, http://gapanalysis.usgs.gov/padus/data/history/.) Due to the completeness and complexity of these data, it is highly recommended to review the Supplemental Information Section of the metadata record as well as the Data Use Constraints, to better understand data partnerships as well as see tips and ideas of appropriate uses of the data and how to parse out the data that you are looking for.

The data on this CD consist of geographic information system (GIS) coverages and tabular data on the geology of Early Proterozoic and Archean rocks in part of the Early Proterozoic Penokean orogeny. The map emphasizes metasedimentary and metavolcanic rocks that were deposited along the southern margin of the Superior craton and were later deformed during continental collision at about 1850 Ma. The area includes the famous iron ranges of the south shore region of the Lake Superior district. Base maps, both as digital raster graphics (DRG) and digital line graphs (DLG) are also provided for the convenience of users. The map has been compiled from many individual studies, mostly by USGS researchers, completed during the past 50 years, including many detailed (1:24,000 scale) geologic maps. Data was compiled at 1:100,000 scale and preserves most of the details of source materials. This product is a preliminary release of the geologic map data bases during ongoing studies of the geology and metallogeny of the Penokean continental margin. Files are provided in three formats: Federal Spatial Data Transfer format (SDTS), Arc export format (.e00) files, and Arc coverages.
