Many provided data or wrote chapters for this report, and this revision was not possible without their contributions. Amber Whittle, Crystal York, Sarah Nappier, and Corday Selden reviewed drafts. Bland Crowder copyedited the final text; Jessica Pernell, Jan Boyett, Robin Grunwald, and Dave Reed provided assistance with report production. Others provided and managed grant funds. We continue to be grateful to those who laid the groundwork for the Seagrass Integrated Mapping and Monitoring (SIMM) program and similar efforts to collate, summarize, and share data on seagrasses in Florida’s coastal waters. Efforts in Tampa Bay and the Indian River Lagoon were especially critical in demonstrating the need for regular assessment of seagrass cover, the link between water quality and seagrass abundance, and the effectiveness of seagrass mapping and monitoring in assessing improvements in water quality. Hundreds of scientists and managers participated in those efforts over decades. Regrettably, only the current project participants are listed in the table that follows and in the individual chapters; but they stand, as does the SIMM team, on the shoulders of those who came before. The second edition of FWRI Technical Report 17 was funded by several grants. Support was provided by Florida’s Wildlife Legacy Initiative and the U.S. Fish and Wildlife Service’s State Wildlife Grants program, grants F12AF00071 (FL T-28-R) Targeted

It is an honor to be associated with Audubon Florida’s work and together, we will continue to Executive Director address the important issues and achieve our mission to protect Julie Wraithmell birds and the places they need. We send a huge thank you to our outgoing Chair, Jud Laird, for his amazing work and Board of Directors leadership — the birds are better off because of your efforts! Summer is here! Locals and visitors alike enjoy sun, the beach, and Florida’s amazing Chair waterways. Our beaches are alive with nesting sea and shorebirds, and across the Heidi McCree Everglades we are wrapping up a busy wading bird breeding season. At the Center Vice-Chair for Birds of Prey, more than 200 raptor chicks crossed our threshold — and we Carol Colman Timmis released more than half back to the wild. As Audubon Florida’s newest Board Chair, I see the nesting season as a time to celebrate the resilience of birds, while looking Treasurer forward to how we can protect them into the migration season and beyond. We Scott Taylor will work with state agencies to make sure the high levels of conservation funding Secretary turn into real wins for both wildlife and communities (pg. 8). We will forge new Lida Rodriguez-Taseff partnerships to protect Lake Okeechobee and the Snail Kites that nest there (pg. 14).

    WALTON COUNTY LAND DEVELOPMENT CODE: CHAPTER 4 | Resource Protection Standards Revised September 10, 2019 Page 2 of 55

    Revised September 10, 2019 Page 1 of 55 CHAPTER IV. RESOURCE PROTECTION STANDARDS 4.00.00. OVERALL PURPOSE AND INTENT The purpose of this chapter is to protect, conserve and enhance Walton County's natural and historical features. It is the intent of the County to enhance resource protection by utilizing development management techniques to control potential negative impacts from development and redevelopment on the resources addressed herein. Specifically, it is the intent of the County to limit the specific impacts and cumulative impacts of development or redevelopment upon historic sites, wetlands, coastal dune lakes, coastal dune lines, water quality, water quantity, wildlife habitats, living marine resources, or other natural resources through the use of site design techniques, such as clustering, elevation on pilings, setbacks, and buffering. The intent of this policy is to avoid such impact and to permit mitigation of impacts only as a last resort. 4.00.01. Permits Required. A. Local Development Order. Unless exempt under Section 1.15.00, a development order is required for all development or redevelopment of real property within the County. As a part of the application process defined in Chapter 1 of this Code, a landowner or developer must apply the provisions of this chapter before any other design work is done for any proposed land development. Application of the provisions of this chapter will divide a proposed development site into zones or areas that may be developed with minimal regulation, zones that may be developed under more stringent regulation and zones that must generally be left free of development activity.

  • Movements, Fishery Interactions, and Unusual Mortalities of Bottlenose Dolphins

    Movements, Fishery Interactions, and Unusual Mortalities of Bottlenose Dolphins

    MOVEMENTS, FISHERY INTERACTIONS, AND UNUSUAL MORTALITIES OF BOTTLENOSE DOLPHINS by STEVE F. SHIPPEE B.S. University of West Florida, 1983 Professional Certificate in Natural Resource Management, University of California San Diego, 2001 A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Biology in the College of Sciences at the University of Central Florida Orlando, Florida Spring Term 2014 Major Professor: Graham A.J. Worthy © 2014 Steve F. Shippee ii ABSTRACT Bottlenose dolphins (Tursiops truncatus) inhabit coastal and estuarine habitats across the globe. Well-studied dolphin communities thrive in some peninsular Florida bays, but less is known about dolphins in the Florida panhandle where coastal development, storms, algal blooms, fishery interactions, and catastrophic pollution have severely impacted their populations. Dolphins can react to disturbance and environmental stressors by modifying their movements and habitat use, which may put them in jeopardy of conflict with humans. Fishery interaction (FI) plays an increasing role in contributing to dolphin mortalities. I investigated dolphin movements, habitat use, residency patterns, and frequency of FI with sport fishing. Dolphins were tracked using radio tags and archival data loggers to determine fine-scale swimming, daily travels, and foraging activity. Dolphin abundance, site fidelity, ranging, stranding mortality, and community structure was characterized at Choctawhatchee and Pensacola Bays in the Florida Panhandle via small boat surveying and photo-identification. Reported increases in dolphin interactions with sport anglers were assessed at deep sea reefs and coastal fishing piers near Destin, FL and Orange Beach, AL. Results from these studies yield insights into the ranging and foraging patterns of bottlenose dolphins, and increase our knowledge of them in the northern Gulf of Mexico.
