A brief overview of the Ecological Assessment of Mainstem Big Rivers in the Gulf Coastal Plains and Ozarks geography.
This folder includes the full minutes from an early SECAS meeting in 2012 and Talking Points from three SECAS Lead Coordination Team meetings in 2016 and 2017.
This report is one in a series developed in a collaboration between Mississippi State University and Duke University to identify opportunities to engage private landowners in the GCPOLCC in conservation and restoration activities by focusing on ecosystem service outcomes that are important to them. There are three main pieces of interrelated work: 1) a survey of landowners to identify what services are important to them and how willing they are to participate in conservation or restoration activities; 2) coarse resolution maps of the provision and where possible demand for ecosystem services in the region; and 3) a social network analysis to understand how best to engage private landowners across the region. The...
Identifying species occurrence in ecosystems of high conservation concern is especially important in the context of modern landscapes. This study investigated how stand-scale and landscape-scale factors affect priority birds associated with longleaf pine (Pinus palutris) ecosystems. Herein, I compared priority bird occupancy among 12 stand types throughout the historic range of longleaf pine. I found open pine stands positively influenced red-cockaded woodpecker (Picoides borealis) and Bachman’s sparrow (Peucaea aestivalis) occupancy, but were not significantly linked to northern bobwhite (Colinus virginianus) and brown-headed nuthatch (Sitta pusilla) occurrence. Landscape- and stand-scale factors affected red-cockaded...

The GCPO LCC assessed landscapes within the broad vegetative class of grasslands at a spatial resolution of 30 meters using a national database of existing vegetation type (LANDFIRE) combined with various high resolution data layers obtained from the states of Oklahoma, Texas, and Florida, and from researchers, non-governmental agencies, and state agencies for Alabama, Arkansas, Mississippi, and Missouri. This process identified over 32 million acres of the grassland vegetative type (broadly defined) and just over 1 million acres meeting the more restrictive definition of prairie (Figure 1). However, none of those areas identified as prairie were shown to meet all four of the condition endpoints assessed, and only...
The Gulf Coastal Plains and Ozarks (GCPO) region is, to a large extent, defined by its mainstem big rivers, with eight of the largest ten rivers (by discharge) in the lower U.S. terminating here. Those rivers are the Mississippi, Ohio, Missouri, Tennessee, Mobile, Atchafalaya, Red, and Arkansas. Whilethis assessment focuses on rivers of the MAV, the analysis has also been extended to big rivers throughout the GCPO.People have historically altered large river systems through the construction of levees and floodways, channelization, and dredging to support agriculture, navigation, commerce, and to provide greater stability and protection from flooding. Many large rivers in the GCPO are, in fact, part of theinland...

The purpose of this Assessment is to understand how much upland hardwood forest and woodland habitat is available and what condition that habitat is currently in relative to habitat targets, or endpoints, defined in the ISA. To assess the ISA endpoints for upland hardwood systems, it was necessary that the most consistent, comprehensive, current and accurate data be used in summary and analysis. For the best possible assessment product we cross-checked geospatial datasets spanning variable time periods and data sources in the Ozark Highlands subgeography and remainder of the GCPO geography.
Draft 2 of the summary report for ecological assessment of estuarine tidal marsh systems along the GCPO LCC Gulf Coast subgeography. This includes an assessment of landscape endpoints identified by the GCPO Adaptation Science Management Team in the draft GCPO LCC Integrated Science Agenda.The estuarine tidal marsh priority system in the Gulf Coastal Plains and Ozarks LCC (GCPO LCC) Integrated Science Agenda (ISA) includes general ecological systems of brackish/saltwater marsh and seagrass beds and was adopted as one of two initial ecological systems of focus for the Gulf Coast subgeography of the GCPO LCC (the other being beaches and dunes). The desired ecological state for Gulf Coast estuarine tidal marsh is a...

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...
Monthly SECAS Lead Coordination Team calls for 2017
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 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.”
