Progress Toward Restoring the Everglades: The Third Biennial Review - 2010 Glossary 8.5-square-mile area—The 8.5-square-mile area (SMA) is a low-lying, partially developed area near the northeast corner of Everglades National Park, west of the L-31 north canal. Flood protection was to have been provided under the original 1989 Mod Waters legislation, but years of subsequent study and negotiations with property owners resulted in a compromise in which a flood protection levee is to be built around approximately two-thirds of the 8.5 SMA while providing for purchase of approximately one-third of the private property and 12 homes in the western portion. Acceler8—An expedited course of action for achieving Everglades restoration. Through Acceler8, the State of Florida intends to implement 11 components of the CERP. Across Trophic Level System Simulation (ATLSS)—A modeling system that uses topographic data to convert the 2 × 2 mile landscape of the regional hydrological models to a 500 × 500 m landscape to which various ecological models are applied. These range from highly parameterized, mechanistic individual-based models (e.g., EVERKITE, SIMSPAR) to simpler, habitat-suitability models (Spatially-Explicit Species Index and Habitat Suitability Index). The objectives of the ATLSS project are to utilize the outputs of systems models to drive a variety of models that attempt to compare and contrast the relative impacts of alternative hydrologic scenarios on the biotic components of South Florida. Aquifer storage and recovery (ASR)—A technology for storage of water in a suitable aquifer when excess water is available and for recovery from the same aquifer when the water is needed to meet peak emergency or long-term water demands. Wells are used to pump water in and out of the aquifer. Best management practices (BMPs)—Effective, practical methods that prevent or reduce the movement of sediment, nutrients, pesticides, and other pollutants

Progress Toward Restoring the Everglades: The Third Biennial Review - 2010 resulting from agricultural, industrial, or other societal activities from the land to surface or groundwater or that optimize water use. Central and Southern Florida (C&SF) Project for Flood Control and OtherPurposes—A multipurpose project, first authorized by the U.S. Congress in 1948, to provide flood control, water supply protection, water quality protection, and natural resource protection. Clean Water Act (CWA)—The Clean Water Act is the cornerstone of surface-water quality protection in the United States. The statute employs a variety of regulatory and nonregulatory tools to reduce direct pollutant discharges into waterways, finance municipal wastewater treatment facilities, and manage polluted runoff. These tools help to achieve the broader goal of restoring and maintaining the chemical, physical, and biological integrity of the nation’s waters so that they can support the protection and propagation of fish, shellfish, and wildlife and recreation in and on the water. Comprehensive Everglades Restoration Plan (CERP)—The plan for the restoration of the greater Everglades ecosystem authorized by Congress in 2000. Conceptual ecological models—Nonquantitative, verbal or diagrammatic hypotheses about the major anthropogenic and natural drivers and stressors on natural systems, the ecological effects of these stressors, and the biological attributes or indicators of these ecological responses. They are used as planning tools for research and adaptive management. Critical Projects—Projects determined to be critical to the restoration of the South Florida ecosystem that were authorized in 1996 prior to the CERP. These projects are comparatively small and were undertaken by the U.S. Army Corps of Engineers and South Florida Water Management District. They are being implemented along with the CERP projects. Decomp—Short title for Water Conservation Area 3 Decompartmentalization and Sheet Flow Enhancement—Part 1 project. Endangered Species Act (ESA)—A U.S. law passed in 1973 to protect species listed by the federal government as threatened or endangered from extinction. It provides penalties for the taking of such species and requires any federal agency to consult with the U.S. Fish and Wildlife Service (or National Marine Fisheries Service for marine species) before undertaking or funding any action that could jeopardize the continued existence or recovery of listed species.

Extirpated species—A species that has become extinct in a given area. Flow—The volume of water that passes a given point per unit of time, including in-stream flow requirements, minimum flow, and peak flow. “Flow” is used generically within the text to mean the movement of volumes of water across the landscape, and it incorporates the concepts of volumetric flow rate (e.g., cubic feet per second), velocity, and direction. Volumetric flow rate may be estimated for large averaging times, such as acre-feet per year, as in the South Florida Water Management Model and the Natural Systems Model, and also on a short-term (“instantaneous”) basis by other models, as discussed in Chapter 4. Flux—The rate of transfer of fluid, particles, or energy across a given surface. Footprint—The area of productive land and aquatic ecosystems required to produce the resources used and to assimilate the wastes produced by a defined population at a specified material standard of living, wherever that land might be located. Foundation projects—Non-CERP Everglades restoration activities, many of which are essential (the foundation) for completion of the CERP. General Circulation Model (GCM)—A numerical model used to simulate the circulation of the ocean (OGCM) or atmosphere (AGCM).

Progress Toward Restoring the Everglades: The Third Biennial Review - 2010 Habitat Conservation Plan—A plan required by Section 10(a)(2)(A) of the Endangered Species Act for an applicant for an incidental take permit. The plan is required to include, among other things, the impacts that are likely to result from the taking and the measures the permit applicant will undertake to minimize and mitigate such impacts. Habitat conservation plans reduce conflicts among listed species and economic use or development activities, allowing for the development of “creative partnerships” between the public and private sectors, designed to make the process work for both landowners and species. Habitat Suitability Index (HSI)—Tool used to define, in relative terms, the quality of the habitat for various plant and animal species. HSIs can be used as the first approximation toward quantifying the relationships identified in various conceptual ecological models. Herbert Hoover Dike—A dike system surrounding Lake Okeechobee that provides flood and storm damage reduction and other water control benefits in central and south Florida. It consists of 143 miles of levees with 19 culverts, hurricane gates, and other water control structures. Hydroperiod—Annual temporal pattern of water levels. Incremental adaptive restoration (IAR)—An alternative framework called for in NRC (2007) for advancing natural resource restoration in the Everglades. The aim of IAR is to resolve decision-critical scientific uncertainties and to address project sequencing constraints to improve the pace of restoration. As conceived, the IAR approach makes investments in restoration project increments that are large enough to secure significant environmental benefits, while simultaneously testing hypotheses selected to resolve important scientific uncertainties about the response of the system to management interventions. Such steps would likely be smaller than the CERP projects because the purpose of IAR is to take actions that help address some sources of delay in the pace of restoration progress as well as to promote learning that can guide the remainder of project design. As an application of adaptive management, IAR would require rigorous monitoring and assessment to test hypotheses, yielding valuable information that can expedite future decision making and improve future project design. Integrated Delivery Schedule (IDS)—The schedule of implementation of restoration projects for the Everglades. It includes Comprehensive Everglades Restoration Plan (CERP) projects and the “Foundation Projects,” those that precede CERP, such as Kissimmee River Restoration and Modified Water Deliveries to Everglades National Park.

Natural System Model (NSM)—Model that simulates hydropatterns before canals, levees, dikes, and pumps were built. The NSM mimics frequency, duration, depth, and spatial extent of water inundation under pre-management (i.e., natural) hydrologic conditions. In many cases, those pre-management water levels are used as a target for hydrologic restoration assuming that restoration of the hydrologic response that existed prior to drainage of the system would lead to restoration of natural habitats and biota. Natural System Regional Simulation Model (NSRSM)—Application of the updated Regional Systems Model to simulate the natural system hydrology of South Florida. The use of refined input parameters, in combination with the model’s improved hydrologic simulation engine, results in simulations that reasonably represent pre-drainage (mid-1800) hydrology within an estimated range of performance. Original Everglades—The pre-drainage Everglades, or that which existed prior to the construction of drainage canals beginning in the late 1800s.

Ridge—Elevated areas of sawgrass habitat that rise above the foot-and-a-half deeper sloughs. A ridge may be submerged or above the water surface. River of Grass Purchase—A proposal to acquire land in the Everglades Agricultural Area for Everglades restoration purposes. The initial proposal would have acquired more than 180,000 acres of land from U.S. Sugar Corporation; economic and legal factors have led to the current proposal, which is to acquire 26,800 acres, with options to acquire an additional 153,200 acres over the next 10 years. Savings Clause—Provision of WRDA 2000 that is designed to ensure that an existing legal source of water (e.g., agricultural or urban water supply, water supply for Everglades National Park, water supply for fish and wildlife) is not eliminated or transferred until a replacement source of water of comparable quantity and quality—as was available on the date of enactment of WRDA 2000—is available and that existing levels of flood protection are not reduced. Sawgrass plain—An unbroken expanse of dense, tall (up to 10 feet) sawgrass that originally covered most of the northern Everglades. Agricultural crops, mainly sugar cane, have replaced most of the sawgrass plain area, but some tall sawgrass remains in the water conservation areas. Sheet flow—Water movement as a broad front with shallow, uniform depth. Slough—A depression associated with swamps and marshlands as part of a bayou, inlet, or backwater; contains areas of slightly deeper water and a slow current and can be thought of as the broad, shallow rivers of the Everglades.

Water Conservation Areas (WCAs)—Everglades marshland areas that were modified for use as storage to prevent flooding, to irrigate agriculture land and recharge well fields, to supply water for Everglades National Park, and for general water conservation. WCA-1, WCA-2A, WCA-2B, WCA-3A, and WCA-3B comprise five surface-water management basins in the Everglades; bounded by the Everglades Agricultural Area on the north and the Everglades National Park basin on the south, the WCAs are confined by levees and water control structures that regulate the inflows and outflows to each one of them. Restoration of more natural water levels and flows to the WCAs is a main objective of the CERP. Water reservations—According to WRDA 2000, the state shall, under state law, make sufficient reservations of water provided by each CERP project for the natural system in accordance with the Project Implementation Report for that project and consistent with the plan before water made available by a project is permitted for a consumptive use or otherwise made unavailable. Water Resources Development Act (WRDA) of 2000—Legislation that authorized the Comprehensive Everglades Restoration Plan as a framework for modifying the Central and South Florida Project to increase future water supplies, with the appropriate quality, timing, and distribution, for environmental purposes so as to achieve a restored Everglades natural system as much as possible, while at the same time meeting other water-related needs of the ecosystem. WRDAs are passed periodically, the most recent one having been enacted in 2007; they provide the mechanism for authorizing CERP activities. Water year—Time convention used as a basis for processing stream flow and other hydrologic data.
