2019 System Status Report Will Also Provide Input Into the 2020 Report to Congress, Required by the Water Resources Development Act of 2000 2019 EVERGLADES SYSTEM STATUS REPORT Assessment period of 2012–2017 A product of the Comprehensive Everglades Restoration Plan (CERP) REstoration COordination and VERification (RECOVER) program This page was intentionally left blank ii acknowledgments As a product of the REstoration COordination and VERification (RECOVER) Monitoring and Assessment Plan (MAP), this report details the evaluation of systemwide performance measures and their targets (or goals) using the ecological tools developed over the past several years under the RECOVER’s MAP program to measure restoration progress. The key findings detailed in the System Status Report can assist decision-makers with the timing of planning and implementation of Comprehensive Everglades Restoration Plan (CERP) features, such as those in the Central Everglades Planning Project (CEPP). This report also serves as a mechanism to inform the scientific community in south Florida. The 2019 System Status Report will also provide input into the 2020 Report to Congress, required by the Water Resources Development Act of 2000. Produced every five years, the intent of the Report to Congress is to inform the highest levels of the U.S. government on the progress made toward the goals and objectives of CERP.

Photo by Franco Tobias. introduction 1.1 everglades restoration Restoring the Everglades is important for south Florida and beyond The Florida Everglades encompasses a network of sub-tropical freshwater wetland and estuarine ecosystems across south Florida. Although it suffered the impact of development during the 20th century, the Everglades remains an invaluable ecological resource. People from around the world visit south Florida because of the unique environment and ecological attributes of the Everglades region. South Florida is home to five national parks, dozens of state parks, refuges and preserves, and numerous rare and endangered species. Tourism and outdoor recreation make a significant contribution to the regional economy. The nearly eight million residents of south Florida depend on the Everglades for their water supply and flood protection. The condition of the Everglades’ ecosystem is critical to many people who live in south Florida, the US, and around the world. Rapid growth and development in south Florida comes at a cost to the Everglades, and threatens the essential natural services that it provides. At the beginning of the past century most of south Florida was a wilderness area. Fewer than 50,000 people lived there in 1900. Today, about 8 million people live there, 41% of Florida’s total population. About half of the original Everglades has been converted for farming and urban land use. The Miami/Fort Lauderdale region is now one of the most densely populated areas in the United States. Beginning in 1948, construction of the Central and Southern Florida Project (now operated by the South Florida Water Management District) for drainage, water supply, and flood protection has permanently altered the region’s hydrology (Figure 1.1). By 2018, over 2,100 miles of canals, 2,000 miles of levees, 657 water control structures, and 77 major pump stations have been constructed to control water levels and flow over an area of

Community information Volusia County is located in the central portion of the Florida east coast. The land area of Volusia County is approximately 1,210 square miles, with 50 miles of Atlantic Ocean shoreline. Along the eastern side of the county, the Halifax River and Indian River/Mosquito Lagoon form long, narrow estuaries which separate the county’s mainland from its barrier island. Ponce DeLeon Inlet, located near the middle of the coastline, serves as the county’s only inlet through the barrier island and the major passage through which Atlantic Tides and storm surge propagate into the estuaries. The Tomoka River and St. Johns River are other major estuaries located in the county. Volusia County has a subtropical climate, with long, warm, and humid summers and short, mild winters. The average annual participation is approximately 48 inches. Over half of this rainfall occurs from June 1 through November 30, the Atlantic hurricane season. 2. Types, causes, and sources of flooding Flooding in Volusia County results from tidal surges associated with hurricanes, northeasters, and tropical storm activity and from overflow from streams and swamps associated with rainfall runoff. Major rainfall events occur from hurricanes, tropical storms, and thundershowers associated with frontal systems. During periods of intensive rainfall, smaller streams tend to reach peak flood flow concurrently due to a relatively short time of concentration, with elevated tailwater conditions associated with coastal storm surge. This greatly increases the likelihood of inundation of low-lying areas along the coast.

Ichthyofauna checklist (Chordata: Actinopterygii) for indicating water quality in Kampar River catchment, Malaysia. Biodiversitas 19: 2252-2274. The limnological habitats are receptors of pollution, thus local fish species richness is a plausible biological indicator to reflect the quality of a particular water body. However, database on species occurrence that corresponds with the water physico-chemistry constituents is often not available. The problem is compounded by the lack of species identification description to assist those working on river and freshwater resource conservation projects. This paper attempts to fill the gaps in the context of Kampar River drainage. Based on sampling exercises conducted from October 2015 to March 2017, an annotated list with visual data for 56 species belonging to 44 genera and 23 families is presented. The water physico-chemistry data is also summarized with the corresponding visual data of limnological zones studied. The species diversity results are further compared with other local drainages and the correlation between area size and their relationship is expressed by y = 17.627e0.0601x.

Zoosystema 39 (4): 501-598. https://doi.org/10.5252/z2017n4a5 ABSTRACT 313 nominal species of monogenean parasites of aquatic vertebrates occurring in Mexico are included in this checklist; in addition, records of 54 undetermined taxa are also listed. All the monogeneans registered are associated with 363 vertebrate host taxa, and distributed in 498 localities pertaining to 29 of the 32 states of the Mexican Republic. The checklist contains updated information on their hosts, habitat, and distributional records. We revise the species list according to current schemes of KEY WORDS classification for the group. The checklist also included the published records in the last 11 years, Platyhelminthes, Mexico, since the latest list was made in 2006. We also included taxon mentioned in thesis and informal distribution, literature. As a result of our review, numerous records presented in the list published in 2006 were Actinopterygii, modified since inaccuracies and incomplete data were identified. Even though the inventory of the Elasmobranchii, Anura, monogenean fauna occurring in Mexican vertebrates is far from complete, the data contained in our Testudines.
