    Description

    This dataset contains the White Mountain National Forest Boundary. The boundary was extracted from the National Forest boundaries coverage for the lower 48 states, including Puerto Rico developed by the USDA Forest Service - Geospatial Service and Technology Center. The coverage was projected from decimal degrees to UTM zone 19. This dataset includes administrative unit boundaries, derived primarily from the GSTC SOC data system, comprised of Cartographic Feature Files (CFFs), using ESRI Spatial Data Engine (SDE) and an Oracle database. The data that was available in SOC was extracted on November 10, 1999. Some of the data that had been entered into SOC was outdated, and some national forest boundaries had never been entered for a variety of reasons. The USDA Forest Service, Geospatial Service and Technology Center has edited this data in places where it was questionable or missing, to match the National Forest Inventoried Roadless Area data submitted for the President's Roadless Area Initiative. Data distributed as shapefile in Coordinate system EPSG:26919 - NAD83 / UTM zone 19N.

    Description

    The present study produced a new reference forest map for China from three land cover products for 2020. These datasets included the World Cover 2020 (ESA-2020), ESRI 2020 Land Cover (ESRI-2020), and the GlobeLand30 version of V2020 (GLC-2020). Within the production of the reference forest map for China, a pixel was assumed to represent forest when the same pixel among multiple land cover products showed forest properties, thereby decreasing the uncertainties of classification of forests at a large scale.

    Description

    Description

    This map represents a classification of forest types based on the influence of the edge effect (distance to the forest edge) and elevation effect (temperature and area) on tree community richness.

    The edge effect influences tree diversity through an environmental aridity filter. In New Caledonia, the maximum temperature recorded at the forest edge is 41°C in February, while it never exceeds 24°C beyond 100 meters from the edge. This temperature difference induces a selection for species that tolerate the most arid conditions, leading to a reduction in the biological richness of tree communities (Ibanez et al., 2017; Birnbaum et al., 2022; Blanchard et al., 2023).

    Altitude also affects tree diversity due to temperature variation and available area (Ibanez et al., 2014; Birnbaum et al., 2015; Pouteau et al., 2015; Ibanez et al., 2016; Ibanez et al., 2018). In New Caledonia, observed tree community richness ranges from 35 to 121 species per hectare within the NC-PIPPN network, peaking at mid-altitude ranges (refer to figure 'amap_elevation_richness.png'). Potential richness was assessed using the S-SDM model, with the 80th percentile used as a threshold to distinguish low and high potential richness across three elevation classes: [0 - 400m[, [400 - 900m[, and [900 - 1628m[.

    The classification of forest types combines distance from the forest edge and potential richness by elevation into three major categories, as illustrated in the figure 'amap_forest_types_nc.png':

    Edge Forest: Parts of the forest located less than 100 meters from the forest edge.

    Mature Forest: Parts of the forest located beyond 100 meters from the edge with a lower potential richness of tree communities.

    Core Forest: Parts of the forest located more than 300 meters from the edge with a higher potential richness of tree communities.

    Content

    The map is computed from the Forest Map of New Caledonia (v2024) and the Potential Tree Species Richness in the Forests of New Caledonia (v2024). This dataset was produced, analyzed, and verified using a combination of open-source software, including QGIS, PostgreSQL, PostGIS, Python, R, and the GDAL library, all running on Linux.

    amap_forest_types_nc.png is a picture illustrating the forest type classification

    amap_forest_types_nc.zip is a compressed file contains the six essential files for an ESRI-format GIS system, using the WGS84 international coordinate system, and can be uploaded to a spatial database such as PostgreSQL/PostGIS. Each row of the attribute table represents a forest type (a multi-polygon) with associated fields :

    Field Type Description

    type TEXT One of the three forest types ("Edge Forest", "Mature Forest", "Core forest")

    area_ha NUMERIC (2 DECIMALS) Area of the multi-polygon in hectares

    description TEXT Description of the three forest types

    geom GEOMETRY (MULTIPOLYGON, 4326)) Geometry with datum EPSG: 4326 (WGS 84 – World Geodetic System 1984)

    Limitations

    We caution users that the distinction between the three classes is based on an ecological interpretation and does not reflect directly perceptible breaks in the forest. The ecological transition from the edge to the core of the forest follows multiple gradient modulated by environmental conditions.

    Moreover, this classification is based on local observations and measurements, which are complex to generalize and extrapolate across a territory as environmentally diverse as New Caledonia. Nevertheless, it allows us to address the impact of fragmentation at the scale of New Caledonia.

    Description

    Initializing forest landscape models (FLMs) to simulate changes in tree species composition requires accurate fine-scale forest attribute information mapped contiguously over large areas. Nearest-neighbor imputation maps have high potential for use as the initial condition within FLMs, but the tendency for field plots to be imputed over large geographical distances results in species frequently mapped outside of their home ranges, which is problematic. We developed an approach for evaluating and selecting field plots for imputation based on their similarity in feature-space, their species composition, and their geographical distance between source and imputation to produce a map that is appropriate for initializing an FLM. We applied this approach to map 13m ha of forest throughout the six New England states (Rhode Island, Connecticut, Massachusetts, New Hampshire, Vermont, and Maine). The map itself is a .img raster file of FIA plot CN numbers. To access FIA data from this map, one has to link the mapcodes in this map to FIA data supplied by USDA FIA database (https://apps.fs.usda.gov/fia/datamart/datamart.html). Due to plot confidentiality and integrity concerns, pixels containing FIA plots were always assigned to some other plot than the actual one found there.

    This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a soil survey area extent format and include a detailed, field verified inventory of soils and miscellaneous areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. A special soil features layer (point and line features) is optional. This layer displays the location of features too small to delineate at the mapping scale, but they are large enough and contrasting enough to significantly influence use and management. The soil map units are linked to attributes in the National Soil Information System relational database, which gives the proportionate extent of the component soils and their properties.

    Description

    Contained within the 3rd Edition (1957) of the Atlas of Canada is a map that shows the portions of land in four condensed maps which illustrate the kind of forest maps that were being prepared from air photographs with a minimum of groundwork by the Forestry Branch of the Department of Northern Affairs and National Resources in the 1950s. Such maps not only show more detail than can be shown on a general forest regions map but also enable sample areas to be located which, when investigated on the ground, provide estimates of timber volumes. These maps are also of value to those responsible for forest protection and the suppression of forest fires. The first of the maps reproduced here illustrates an area of almost continuous forest in the rough terrain of the Alberta foothills (from sheet 82 0/14 - Marble Mountain). The second shows forested areas broken only by a few scattered farms (from sheet 31 0/10 - Mitchinamecus River, Quebec). The third shows an area almost equally divided between farm and forest (from sheet 21 J/7 - Napadogan, New Brunswick) The remaining map represents a farming district with scattered woodlots (from sheet 31 H/1 - Memphremagog, Quebec).

    1.1.1 Forest Service Mapping Series 6 (FSMS6)

    The 23 completed maps provide the distribution of indigenous forest vegetation for all of the North Island and the bulk of the South Island at a scale of 1:250,000. These maps were primarily compiled by Mr John Nicholls with some of the South Island maps compiled by Mr Dudley Franklin. Black and white aerial photographs, dating from 1948 to 1955 and at a scale of 15 chains per inch, supplemented by extensive ground truthing and some 16,000 National Forest Survey and Ecosurvey plots, were used to determine forest class boundaries. These were transferred to 1:63360 topographic maps. The maps were field checked and then copied for production by FRI graphics staff (Herbert 1997, pers. comm.).

    Most maps were completed by the NZ Forest Service, with a small number being finished by the Ministry of Forestry and then by Landcare Research Ltd. Appendix 1 gives the list of maps digitised. The date of the photographs that were used to compile each map is not known exactly.

    1.1.2 Forest Service Mapping Series 15 (FSMS15)

    There are two FSMS15 comprising 1:1,000,000 maps of the North Island, and South Island (including Stewart Island). These were compiled by NZFS Conservancy and Head Office staff for the 1974 Forestry Development Conference. Forest boundaries for the 1:1,000,000 FSMS15 maps are significantly less accurate than those for the 1:250,000 FSMS6 maps (Herbert and Nicholls, 1997, pers. comm.). Data sources included existing FSMS6 maps (with 18 classes coalesced into eight super classes), local published and unpublished maps and local knowledge for areas not cover by the FSMS6. The Te Anau, Hauroko and Mataura FSMS6 series maps were substituted for by the South Island FSMS15 map.

    1.1.3 Forest Service Type Map Series No. 2 (FSTM2)

    These are a collection of detailed forest class maps at 1:63360 scale. Coverage is confined to parts of the central North Island.

    ### 1.1.4 Vegetation of Stewart Island

    Mr Hugh Wilson (Wilson, 1987) developed a detailed map of the vegetation of Steward Island. Wilson’s Podocarp/hardwood forest, and rata-kamahi hardwood forest polygons (Types A 1-2, B3) were digitised.

    1.2 Forest Class Description

    There are eighteen forest classes described in the FSMS6 map series. These are described in Table 1. The source is Nicholls and Herbert (1995). FSMS15 has eight super classes and these are defined in Table 2.

    2. METHODS

    2.1 Digitising and Topology Generation

    The maps were digitised by staff at the Forest Research Institute under standards listed in Appendix 2, using the Terrasoft Geographic Information System. The linear features that made up each forest class polygon are shared between two feature classes one, called NZFS6 which contains the national coverage, and the other based on the respective map sheet number. This allows themes to be developed for a national view and also for the individual map sheets.

    The line work is topologically correct with no over-, or under- shoots.

    Each polygon has a nationally unique identifier and which is linked to a dbase table containing a code letter which describes the forest vegetation class.

    These maps were digitised for the purpose of providing indigenous forest vegetation cover for usage at a national scale. There has been no formal checking of the accuracy of the digitised linework. Any errors are considered to be insignificant for determining a 1990 indigenous forest vegetation baseline database. Each polygon was checked to confirm correct tagging. During that process any significant linear differences were noted and corrected.

    2.2 Problems

    2.2.1 Incorrect map details

    In several places errors on the maps were found. Either the FSTM2 maps were consulted for greater detail where coverage existed or Mr John Nicholls was, personally, consulted and the error corrected.

    2.2.2 Map source quality

    Most FSMS6 maps where unused, unfolded sheets with only sheet 12 being an unused folded map. The FSMS15 South Island map was a well used map with significant fold lines. This map also had other printed information which made precise measurement of some forest class boundaries difficult.

    Standards

    This document defines the standards used for digitising the forest class maps (NZFS Map Series 6, FSMS15 and Wilson, 1987).

    Source

    The source of the FSMS6 data is the 1:125,000 flat map sheets, the FSMS15 maps and the Vegetation map contained in Wilson (1987).

    Digitising

    The following digitising standards were used.

    A minimum of five points for registration should be selected from a rectangular range encapsulating the immediate digitising area. These points then should he entered into Convert and both the input and the resultant NZMG coordinates checked before the map is registered. The registration error should be (in Terrasoft) 0.00%. The media should be anchored firmly to the digitiser. The RMU laboratory should be used with the air conditioning turn on. Registration should occur at least twice a day, but occur more frequently if the humidity changes. All lines and polygon which represent a forest type needs to be captured irrespective of size. All intersections should have a node digitised. The two feature classes are NZFS6 and NZFS6_

    Output

    Shape must be identical

    Theme creation

    A Theme will be created for each map sheet. The national NZFS6 theme will be created by including the previously digitised map sheets and the FSMS15 and Wilson’s map. Polygon tags are to be corrected between the map sheets to make them all unique. All dangles and overlaps, and bad polygons are to be corrected.

    Tagging

    All polygons are to be tagged with a code representing the forest type. All sliver polygons are to be removed.

    Checking

    A plot should be created at the original scale and overlayed over the original map. Each polygon is checked to confirm correct tagging.

    Description

    The base data set used in this forest fragmentation analysis is the 2010 C-CAP Land Cover Analysis (http://http://coast.noaa.gov/ccapftp/). Land cover categories that were considered 'forest' for this analysis include Deciduous Forest, Evergreen Forest, Mixed Forest, Estuarine Forested Wetland, and Palustrine Forested Wetland. Two buffered roads layers were erased from the forest polygons, in order to approximate the fragmenting effect of roads on the landscape. Because the area of interest crosses the boundaries of multiple states, the ESRI North America Detailed Streets layer (http://www.arcgis.com/home/item.html?id=f38b87cc295541fb88513d1ed7cec9fd) was used. Two selections of the roads data were extracted and buffered: Interstate roads were buffered 150 feet from the center line in both directions, while US, State, and County roads were buffered 33 feet from the center line. The final data set is limited to forest patches falling within a 5 mile radius of either the Hudson River Estuary watershed boundary or the 10 counties of New York's Hudson Valley.The accompanying symbology layer divides forests into four size classes following the Orange County Open Space Plan (Orange County Planning Department 2004): Globally important (greater than 15,000 acres). These large and intact forest ecosystems support characteristic, wide-ranging, and area-sensitive species, especially those that depend on interior forest. Globally important forests are large enough so over time they will express a range of forest successional stages including areas that have been subjected to recent large-scale disturbance such as blowdowns and fire, areas under recovery, and mature areas. These forests also provide sufficient area to support enough individuals of most species to maintain genetic diversity over several generations. Regionally important: (6,000 - 14,999 acres). Patches 6,000 acres and greater provide habitat to more area-sensitive species and can accommodate large-scale disturbances that maintain forest health over time. Smaller patches are often less able to maintain the entire range of needed habitats and successional stages after large-scale disturbances. Locally important: 2,000 – 5,999 acres). These smaller but locally important forest ecosystems often represent the lower limit of intact, viable forest size for forest-dependent birds. Such bird species often require 2,500 to 7,500 acres of intact interior habitat. These forests, like the larger regionally important forests, can also provide important corridors and connectivity among forest ecosystems. Stepping stone forests: (200 – 1,999 acres) These examples of smaller forest ecosystems provide valuable, relatively broad corridors (not just a narrow strip) and links to larger patches of habitat such as local, regional, and global forests. These smaller forests, therefore, enable a large array of species, including wide-ranging and area-sensitive species, to move from one habitat to another across an otherwise hostile and fragmented landscape. They also provide important habitat at key times during many animals’ life cycles. These forests should be considered the absolute minimum size for intact forest ecosystems. Forests as small as 200 acres will support some forest interior bird species, but several may be missing, and species that prefer “edge” habitats will dominate. Forest patches less than 200 acres have lesser ecological significance at the landscape scale and were excluded from the symbology layer, However, smaller forests may have local importance, and can be viewed by changing the symbology settings.

    Description

    Wildlands in New England is the first U.S. study to map and characterize within one region all conserved lands that, by design, allow natural processes to unfold with no active management or intervention. These “forever wild lands” include federal Wilderness areas along with diverse public and private natural areas and reserves. Knowing the precise locations of Wildlands, their characteristics, and their protection status is important as both a baseline for advancing conservation initiatives and an urgent call to action for supporting nature and society. Wildlands play a unique role in the integrated approach to conservation and land planning advanced by the Wildlands, Woodlands, Farmlands & Communities (WWF&C) initiative, which calls for: at least 70 percent of the region to be protected forest; Wildlands to occupy at least 10 percent of the land; and all existing farmland to be permanently conserved. This research was conducted by WWF&C partners Harvard Forest (Harvard University), Highstead Foundation, and Northeast Wilderness Trust, in collaboration with over one hundred conservation organizations and municipal, state, and federal agencies. This dataset contains the Geographical Information System (GIS) polygon layer of Wildlands created by this project and used in all analyses for the 2023 report. Another GIS layer will be updated as new Wildlands are brought to our attention or created and will be available at https://wildlandsandwoodlands.org/ for researchers.

    Description

    This document is the result of the cadastral consolidation during the fourth forest resource survey. It is mainly based on the second revised forest management area map completed in 2009 and the cadastral data applied to the Ministry of the Interior in 2014. The cadastral boundaries managed by this authority were reorganized to align with the forest management area boundaries. This mapping production task was carried out by the various forest management offices within their respective jurisdictions to adjust and revise the forest management area boundaries. The task was completed from early 2014 to early 2015 and then handed over to the Agricultural Aviation Engineering Division for map verification and consolidation, with the forest compartment boundaries and coding based on the second round revised forest compartment map. As a result, the new map's forest compartment boundaries are consistent with those of the second round revised version, with only some adjustments made to areas adjoining forest land outside the area to align with the cadastral and forest management area boundaries.

Description

This dataset contains the White Mountain National Forest Boundary. The boundary was extracted from the National Forest boundaries coverage for the lower 48 states, including Puerto Rico developed by the USDA Forest Service - Geospatial Service and Technology Center. The coverage was projected from decimal degrees to UTM zone 19. This dataset includes administrative unit boundaries, derived primarily from the GSTC SOC data system, comprised of Cartographic Feature Files (CFFs), using ESRI Spatial Data Engine (SDE) and an Oracle database. The data that was available in SOC was extracted on November 10, 1999. Some of the data that had been entered into SOC was outdated, and some national forest boundaries had never been entered for a variety of reasons. The USDA Forest Service, Geospatial Service and Technology Center has edited this data in places where it was questionable or missing, to match the National Forest Inventoried Roadless Area data submitted for the President's Roadless Area Initiative. Data distributed as shapefile in Coordinate system EPSG:26919 - NAD83 / UTM zone 19N.
