15th Annual Public Meeting on the Long-Term Plan for Achieving Water Quality Goals for Everglades Protection Area Tributary Basins Vegetation Conditions in the Everglades Stormwater Treatment Areas Eric Crawford February 23, 2018 Vegetation Management Goals ▪ Manage vegetation in the STAs in order to maintain sustainable phosphorus uptake processes and mechanisms ▪ Increase treatment redundancy and durability ▪ Increase the genetic and species diversity of beneficial plants for structural stability and P uptake ▪ Manage invasive/nuisance vegetation to minimize its spread throughout the STAs and downstream, and reduce the impact on desired vegetation and performance. 2 STA 1 EAST ISSUES ACTIONS STATUS EASTERN FLOW-WAY CONVERSION FROM USACE PASTA ESTABLISH EMERGENT VEGETATION IN RESTORATION UNDER WAY, GROW- IN IS RESEARCH SITE TO AN ACTIVE FLOWAY CELL 1 AND SAV WITH VEGETATION PROCEEDING NICELY AND IS MOSTLY COMPLETE STRIPS IN CELL2, CONTROL TORPEDO PERFORMANCE IS EXCELLENT HEAVY FAV INFLOWS AND INVASIVE GRASS AN PRIMROSE WILLOW, PLANTS INOCULATE CELL 2 WITH CHARA AND SOUTHERN NYAD CENTRAL FLOW-WAY HEAVY FAV INFLOWS, EXTENSIVE ESTABLISH THALIA AND BULRUSH THALIA AND BULRUSH PLANTINGS PRIMROSE WILLOW STANDS POOR STANDS FOR EXPANSION, INCREASE COMPLETED FOR FY 2017, ADITIONAL TOPOGRAPHY, HYDRAULIC SHORT- TREATMENT OF PRIMROSE WILLOW, EAV AS WELL AS LOTUS AND LILY CIRCUITING, POOR CATTAIL EXPAND PLANTINGS AND SPECIES PLANTINGS SCHEDULED FOR FY 2018 RECRUITMENT DIVERSITY WESTERN FLOW-WAY HEAVY FAV INFLOWS, CELLS 5 AND 7 TREAT THE FAV AND HYDROCOTYLE RESTORATION PLANNED AND HAVE HISTORICAL POOR CATTAIL BEDS, INCREASE COVER OF EAV IN UNDERWAY FOR FY 2018 AND 2019 SURVIVAL AND RECRUITMENT, CELSL 5 AND 7, ESTABLISH WATER LILY, EXCESSIVE FAV INFLOWS,WIDESPREAD LOTUS AND SAV BEDS IN CELL 6 SOIL DELAMINATION, HYDRAULIC SHORT CIRCUITS IN CELL 6 3 Cell 7 Plantings 44 Cell 7 Plantings 55 STA 1 WEST ISSUES ACTIONS STATUS NORTHERN FLOW-WAY HEAVY FAV INFLOWS, CELL 5A HAS ESTABLISH EMERGENT VEGETATION IN RESTORATION UNDER WAY IN CELL 5B , TOPOGRAPHICAL AND HYDRAULIC CELL 5B AND INCREASE THE NUMBER OF GROW- IN IS PROCEEDING NICELY AND SHORT CICUITING ISSUES, EXENSIVE CUTS AT THE INFLOW BERM OF 5A TO PERFORMANCE IS STILL GOOD.
