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...

This Ecological Assessment includes a large proportion of rivers and streams throughout the GCPO but excludes the smaller and steeper streams that are most abundant across the Ozark Highlands, Ouachita Mountains (WGCP), and higher elevations of the East Gulf Coastal Plains. We defined medium-sized streams and rivers as free-flowing streams with an average annual flow of 10 to 6,000 cubic feet/sec (cfs) and sitting at an elevation <=130 meters according to the National Hydrography Dataset (v2). Our Condition Index showed a majority of medium-low gradient streams in the region are impacted by land use, with most of the higher ranking streams in the pine belt. Most targets cannot be reliably assessed with existing...
The designation of “medium-low gradient streams and rivers” is very broad in that it relies on only gradient to define it. This designation includes a large proportion of rivers and streams throughout the EWGCP but excludes the smaller and steeper streams that are most abundant across the Ozark Highlands and Ouachita Mountains of the West Gulf Coastal Plain (WGCP), and at higher elevations of the East Gulf Coastal Plain (EGCP). Within this broadly defined habitat type, landscape endpoints specified in the Integrated Science Agenda (ISA) describe localized stream amount, configuration and condition. These endpoints are further broken down into measures of sinuosity, temperature, riffle-pool sequences and physical...
The objectives of this open pine and woodland rapid ecological assessment are to provide information about (1) how much and where the pine-dominated landscapes in the GCPO meet the criteria for open pine habitat as defined in the Integrated Science Agenda (ISA), (2) how much more such habitat is needed, and (3) where opportunities exist to manage for these conditions (through thinning, burning, reforestation, enhancement, etc.). The ISA defines the desired ecological state for open pine as “woodlands and savannas that are floristically rich and comprised mostly of site-appropriate pine with low basal area, open canopies, and dense herbaceous understories in large interconnected blocks.”
This data represents an assessment of forest patch size 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...

The desired ecological state for priority habitat systems should characterize the least impacted condition – systems in this condition should be targets for maintenance/protection and the goal of restoration activities in degraded systems. In the GCPO LCC Integrated Science Agenda (ISA), ageneral description of the desired ecological state for high gradient streams and rivers of the Ozark Highlands is: “Small springs, runs, and headwaters characterized by clear, clean, and relatively cold water in largely undisturbed forest settings.”To identify high gradient streams, a threshold of 2% slope was originally chosen to align with categories of “high” and “very high” established by the Southeast Aquatic Resources Partnership...

The Adaptation Science Management Team adopted the broadly defined habitat type of “medium-low gradient rivers and streams,” as a priority habitat within the GCPO geography. The desired landscape endpoint for these rivers and streams should characterize a natural system in a least impacted condition – systems in this condition should be targets for protection and the goal of restoration activities in degraded systems. Landscape endpoints specified in the GCPO Integrated Science Agenda (ISA) are intended to more narrowly describe localized stream amount, configuration and condition. In the ISA, a general description of desired landscape endpoints for medium-low gradient streams and rivers include intact channel...
High gradient streams and rivers of the Ozark Highlands were selected by the Gulf Coastal Plains and Ozarks (GCPO) Adaptation Science Management Team (ASMT) as a priority habitat system. The goal of this document discover and apply geospatial data and analysis to estimate the amount, configuration and condition of key habitat features of high gradient streams and rivers of the GCPO. The desired ecological state for priority habitat systems should characterize the least impacted condition – systems in this condition should be targets for maintenance/protection and the goal of restoration activities in degraded systems. In the GCPO Integrated Science Agenda (ISA), a general description of the desired ecological...
A brief overview of the ecological assessment of upland streams and rivers in the Gulf Coastal Plains and Ozarks geography.
The Mississippi River alluvial floodplain formerly held one of the largest expanses of bottomland hardwood forest in North America. It is also one of the most impeded systems on the continent, with altered hydrology from a vast network of protection levees and most naturally occurring bottomland forests long ago converted to agriculture across the majority of the Mississippi Alluvial Valley (MAV). In the MAV, forested wetland systems include alluvial bottomland hardwoods, cypress-tupelo forests, lower flatwoods and riparian forests associated with the Mississippi River. These systems support several species of conservation concern that the GCPO LCC Integrated Science Agenda (ISA) designates as representative...

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 Gulf Coastal Plains and Ozarks (GCPO) Landscape Conservation Cooperative (LCC) has conducted an ecological assessment of various landscape characteristics, or endpoints, outlined in the LCC Integrated Science Agenda. This data layer addresses the forested wetland amount desired landscape endpoint for the forested wetland ecosystem in the Mississippi Alluvial Valley subgeography of the GCPO LCC. This data was created by reclassification of the 2011 National Land Cover Dataset (NLCD) to pull out only the woody wetlands class (90) from the NLCD dataset. We then overlaid the HUC12 watershed layer and calculated the total amount of forested wetland acreage within each watershed.

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...

Description of condition index value scores for estuarine tidal marsh along and within 10 km of the GCPO LCC Gulf Coast subgeography. A series of raster calculations were used in a dichotomous decision-based framework to compile a per-pixel draft condition index value at a 10 m resolution for GCPO estuarine tidal marsh based on the number of configuration and condition endpoints met within each marsh pixel. Pixels not identified as a estuarine marsh but that were identified as having the potential to be marsh were given a score of 1, provided the pixels were not classified as developed. Potential estuarine tidal marsh pixels were derived from a combination of potential estuarine tidal marsh classes in the Landfire...

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],...

The Gulf of Mexico is estimated to contain nearly half of all U.S. salt marsh systems, which are rapidly disappearing within the Gulf States. Salt marshes are complex, dynamic, and transitional systems that provide habitat for a myriad of wildlife species, filtration that supports water quality, and natural barriers that contribute to the security of inland coastal areas. Loss of coastal wetlands and degradation of estuarine habitat along the northern Gulf of Mexico, and particularly along coastal Louisiana have been recognized as two of the primary issues influencing Gulf ecosystem integrity.Several multi-agency consortiums, including the Gulf Coast Ecosystem Restoration Task Force, have identified conservation...
