This data represents an assessment of forest composition used in the ecological assessment of upland hardwood systems by the GCPO LCC. We used a combination of remote sensing products including 2011 National Land Cover Database (NLCD) forest classes and the 2011 MAV forest classification layer produced by the Lower Mississippi Valley Joint Venture to delineate patches of all forest types in the GCPO LCC. We used NLCD as the primary data source when assessing forests outside the GCPO LCC MAV subgeography, and the LMVJV forest classification as the primary data source for forest assessment within the MAV. NLCD was developed using 2011 Landsat TM imagery, with forest classes including only areas with trees exceeding...

Standing dead trees, or snags, are an important habitat element in any forested system, and provide diurnal or seasonal shelter for many LCC priority species. The ISA landscape endpoint for snag density in upland hardwood woodland and forest systems targets one large (≥16” dbh) snag for every five acres of forest (or approximately ~0.2 large snags/acre), reflected by cavity-roosting habitat needs of the silver-haired bat (Lasionycteris noctivagans) and ample other avian, and mammalian species that require cavities in snags to carry out their life history. We used USFS imputed density of large (>16” dbh) snags data (USDA Forest Service Remote Sensing Applications Center, personal communication) extracted through...

Limited midstory density was also identified in the Integrated Science Agenda as an important component of upland hardwood systems in the GCPO geography, with midstory coverage ≤20% indicating a healthy additional vertical strata in the system. Midstory is an important habitat component for several ISA priority species, particularly those avian species who require midstory structure for nesting such as the wood thrush (Hylocichla mustelina). We again used plot-level Forest Inventory and Assessment data imputed at 250 m resolution across the GCPO LCC to assess tree density. The USFS imputed tree density data product provides raster maps for the conterminous U.S. generated using 250 m resolution MODIS satellite imagery,...

These data were created to describe the causes of land cover change that occurred in the Interior Highland region of the United States for the time intervals of 2001 to 2006 and 2006 to 2011. This region, which covers approximately 17.5 million hectares, includes portions of the U.S. states of Arkansas, Missouri, Oklahoma, and Kansas. Most of the area is covered by gently rolling hills of forests and pastureland. Two raster maps were created at a 30-meter resolution showing the causes of land change using automated and manual photo interpretation techniques. There were 30 categories of land change causes (i.e., forest harvest or surficial mining) discovered over the Interior Highlands. These categories can be used...

We developed a composite land cover approach for use in the GCPO LCC ecological assessment of upland hardwood woodlands and forests. These datasets reflect the upland hardwood “mask” that represents the composite of 3 or 4 datasets, from which the remaining landscape endpoints defined in the LCC Integrated Science Agenda will be evaluated. The mask indicates where on the landscape we estimate upland hardwood woodlands and forests to be found in any condition. We first resampled 30 m 2011 GAP ecological systems land cover and Florida Cooperative Land Cover version 3.1, as well as 10 m Texas and Oklahoma Ecological Systems Mapping land cover data to 250 m using a nearest neighbor algorithm. The assessment was conducted...

Dead and downed wood in any forest serves an important ecological function with regards to decomposition and nutrient cycling in forest ecosystems. It also provides critical habitat for many reptile and amphibian species, such as the red-backed salamander (Plethodon cinereus), in addition to providing an important food source for insects and detritivores upon which many other species in the system depend. The GCPO LCC Integrated Science Agenda (ISA) targets density of down wood around one 6’ dead/down log of ≥8” dbh per acre, essentially saying that on every acre there needs to be at least one sizable down log. The U.S. Forest Service (USFS) Forest Inventory and Analysis program does not collect plot-level data...

These layers represent estimates of imputed tree density calculated as part of the ecological assessment of upland hardwood systems. The GCPO Integrated Science Agenda targets tree densities of around 40 trees/acre for upland hardwood woodland systems and around 80 trees/acre for upland hardwood forest systems. These metrics should be correlates with target endpoints of basal area and canopy cover, though not entirely synonymous. We again used plot-level FIA data imputed across the GCPO LCC to assess tree density. However, it was challenging to identify and map the very limited acreage amounts meeting exactly this target in upland hardwood woodlands and forest. We therefore assessed the mean tree density within...

Springs and sinkholes in the Ozark Plateaus Physiographic Province (Ozarks) in Arkansas were digitized from 1:24,000-scale topographic maps to produce a digital dataset of karst features. Karst landscapes generally are created from bedrock dissolution that results in distinctive landforms, including sinkholes, springs, caves, and sinking streams, and a high degree of interaction between surface water and groundwater. The dataset can be used to better understand groundwater flow in the karst landscape of the Arkansas Ozarks and potential effects of karst-feature density on water quality, geomorphology, water resources, and karst hazards. In the Ozarks, karst features are present in several limestone and dolomite...

Ecological conditions within forest stands are also important indicators of ecosystem integrity. Priority wildlife species are frequently shown to exhibit preference for a specific range of conditions of canopy cover and basal area, tree diameter, midstory cover, and other forest characteristics within a stand. The ISA recommends a range of overstory canopy cover between 20-80% for upland hardwood woodlands and >80% for upland hardwood forests in the Ozark Highlands subgeography. We used the 2011 National Land Cover Database (NLCD) U.S. Forest Service Tree Canopy (analytical) product (USDA Forest Service Remote Sensing Applications Center 2014) combined with the woodland and forest masks derived above for assessment...

The U.S. Geological Survey's Water Availability and Use Science Program (WAUSP) is conducting an assessment of groundwater availability throughout the United States to gain a better understanding of the status of the Nation's groundwater resources and how changes in water use and climate may affect those resources. Assessments will be completed for the Nation's principal aquifer systems to help characterize how much groundwater is currently available, how groundwater availability is changing, and how much groundwater we can expect to have in the future (Source: USGS). Groundwater is an important resource in the Ozark Plateaus area, therefore WAUSP is supporting a groundwater availability assessment of the Ozark...

The Ozark Plateau aquifer system stretches across approximately 70,000 square miles (mi2) of Arkansas, Missouri, Kansas and Oklahoma, and is composed of many hydrogeologic units, such as the Boone aquifer and the Roubidoux aquifer. However, this data release is focused on only 11,000 mi2 in northern Arkansas, southeastern Kansas, southwestern Missouri, and northeastern Oklahoma. The Boone aquifer covers approximately 10,700 mi2 of this area, and the Roubidoux aquifer covers the 11,000 mi2 area entirely. These aquifers are mostly made of Mississippian-aged and Ordovician-aged carbonate rock, and serve as the main sources of fresh groundwater in northeastern Oklahoma (Imes and Emmett, 1994). In 2017, the U.S. Geological...

Temporal dynamics of each GCPO priority system are recognized as important contributors to the overall system integrity. The Integrated Science Agenda (ISA) alludes to the desired condition that forest structure should be dominated by mature upland hardwood stands across the greater landscape. However, to ensure future forest sustainability a small portion (≤10% of the landscape) should be in a state of regeneration, or early forest succession. The ISA provides this endpoint as a general target, but lacks specificity regarding the desired composition of forest stand ages because there is limited literature available that assesses upland hardwood stand age from an ecosystem integrity perspective. Priority wildlife...

Average tree diameter (dbh) is also an important forest condition for some species requiring large trees and subsequent tree cavities for denning/nesting/roosting sites. The GCPO LCC ISA targets diameter of upland hardwood forest and woodland trees to be ≥14” dbh. The standardized Forest Inventory and Analysis (FIA) national program, which collects data using standardized field protocols across counties in every state annually, may be the only landscape-scale data source feasible to investigate average tree diameter in the absence of other large-scale data sources in the GCPO geography. We used FIA-imputed data on average tree diameter (DBH, inches) (USDA Forest Service Remote Sensing Applications Center [USFS],...

Basal area is a measure of the cross-sectional area of trees calculated by multiplying the foresters’ constant (0.005454) by the squared diameter of each tree to determine a measure of tree area (ft2 or m2) per unit area (acre or ha). Similar to an assessment of forest canopy cover, basal area provides a measure of horizontal structure, and is closely associated with measures of vertical structure. When assessing condition of upland hardwood woodland and forest systems, the GCPO LCC Integrated Science Agenda targets a large proportion of the basal area in those systems to be composed of oak and hickory species. This endpoint targets >90% of basal area as oak and hickory for upland hardwood woodland systems and >70%...
