Carica papaya ● Water Science & Plants Protecting Endangered Plant Species Sweetwater slope: Bill and Pam Anderson To date, a total of 117 listed taxa have been recorded in 26 panhandle parks, making these parks a key resource for the protection of endangered plant species. 4 ● The Palmetto Volume 28:1 ● Winter/Spring 2011 in Panhandle State Parks by Gil Nelson and Tova Spector The Florida Panhandle is well known for its natural endowments, chief among which are its botanical and ecological diversity. Approximately 242 sensitive plant taxa occur in the 21 counties west of the Suwannee River. These include 15 taxa listed as endangered or threatened by the U. S. Fish and Wildlife Service (USFWS), 212 listed as endangered or threatened by the State of Florida, 191 tracked by the Florida Natural Areas Inventory, 52 candidates for federal listing, and 7 categorized by the state as commercially exploited. Since the conservation of threatened and endangered plant species depends largely on effective management of protected populations, the occurrence of such plants on publicly or privately owned conservation lands, coupled with institutional knowledge of their location and extent is essential.

IMPACTS OF LAUREL WILT DISEASE ON NATIVE PERSEA OF THE SOUTHEASTERN UNITED STATES A Dissertation Presented to the Graduate School of Clemson University In Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy Forest Resources by Timothy M. Shearman May 2016 Accepted by: Dr. G. Geoff Wang, Committee Chair Dr. Saara J. DeWalt Dr. Donald L. Hagan Dr. Julia L. Kerrigan Dr. William C. Bridges ABSTRACT Laurel Wilt Disease (LWD) has caused severe mortality in native Persea species of the southeastern United States since it was first detected in 2003. This study was designed to document the range-wide population impacts to LWD, as well as the patterns of mortality and regeneration in Persea ecosystems. I used Forest Inventory and Analysis (FIA) data from the U.S. Forest Service to estimate Persea borbonia (red bay) populations from 2003 to 2011 to see if any decline could be observed since the introduction of LWD causal agents.

The Ericaceae is very important in our area, with a great diversity of genera and species, many of them rather narrowly endemic. Our area is one of the north temperate centers of diversity for the Ericaceae. Along with Quercus and Pinus, various members of this family are dominant in much of our landscape.

Barr — Executive Director ABOUT THE NORTHWEST FLORIDA WATER MANAGEMENT DISTRICT The Northwest Florida Water Management District is one of five water management districts in Florida, created by the Water Resources Act of 1972 (Chapter 373, Florida Statutes) to address regional water resource issues while furthering statewide goals and policies. The District stretches from the St. Marks River Basin in Jefferson County to the Perdido River in Escambia County, covering approximately 11,305 square miles, or 17 percent of the state’s geographic area. There are 63 incorporated cities within the District. It is bordered on the north by Georgia and Alabama, on the west by Alabama, on the south by the Gulf of Mexico, and on the east by the Suwannee River Water Management District, which shares Jefferson County with the District. The District has worked for decades to protect and manage water resources in a sustainable manner for the continued welfare of people and natural systems across its 16-county region.

    Environmental Management Chapter 335-6-11 DEPARTMENT OF ENVIRONMENTAL MANAGEMENT WATER DIVISION - WATER QUALITY PROGRAM ADMINISTRATIVE CODE CHAPTER 335-6-11 WATER USE CLASSIFICATIONS FOR INTERSTATE AND INTRASTATE WATERS TABLE OF CONTENTS 335-6-11-.01 The Use Classification System 335-6-11-.02 Use Classifications 335-6-11-.01 The Use Classification System. (1) Use classifications utilized by the State of Alabama are as follows: Outstanding Alabama Water ................... OAW Public Water Supply ......................... PWS Swimming and Other Whole Body Shellfish Harvesting ........................ SH Fish and Wildlife ........................... F&W Limited Warmwater Fishery ................... LWF Agricultural and Industrial Water Supply ................................ A&I (2) Use classifications apply water quality criteria adopted for particular uses based on existing utilization, uses reasonably expected in the future, and those uses not now possible because of correctable pollution but which could be made if the effects of pollution were controlled or eliminated. Of necessity, the assignment of use classifications must take into consideration the physical capability of waters to meet certain uses. (3) Those use classifications presently included in the standards are reviewed informally by the Department's staff as the need arises, and the entire standards package, to include the use classifications, receives a formal review at least once every three years. Efforts currently underway through local 201 planning projects will provide additional technical data on certain waterbodies in the State, information on treatment alternatives, and applicability of various management techniques, which, when available, will hopefully lead to new decisions regarding use classifications. Of particular interest are those segments which are currently classified for any usage which has an associated Supp.

  • Biological Opinion for Johnson Beach Area Project
    Executive Summary We, the U.S. Fish and Wildlife Service (USFWS), have evaluated the impacts of the proposed Gulf Islands National Seashore/Johnson Beach Area (GINS) parking lot improvement project to be developed on the east end of Perdido Key in Escambia County, Florida. GINS encompasses 1,041 acres with high visitor use, primarily beach and Gulf of Mexico access. Coastal dune habitat can be found adjacent to the open beach. It is this habitat that supports the federally endangered Perdido Key beach mouse (Peromyscus polionotus trissyllepsis) (PKBM). Gulf Islands National Seashore is one of three core population areas for PKBM. These core areas support the main population of PKBM and without them extinction would likely be near. GINS operates under a General Management Plan that supports management for PKBM and other protected species and their habitat. This parking lot expansion project aims to focus visitor use of the beaches to and through specific corridors to avoid critical and sensitive habitat. Currently the main parking lot holds 323 vehicles with additional roadside parking along both sides of the 1.2 mile paved park road. This road routinely gets covered in sand and requires regular maintenance to plow and remove. The focus of this expansion project is to remove the roadside parking, expand the main parking lot, and add three additional small parking lots along the park road. The entry way will also be expanded from a single entry and exit road to double entry/exit lanes. Removing and replacing dune walkovers, installing split rail fence and post and rope will direct pedestrian use from these parking areas to the open beach with limited disturbance to the habitat and species in the area.

    Bulk Rate U.S. Postage Paid Permit No. 1013 Foley, AL 36535 Friends of Perdido Bay ADDRESS SERVICE REQUESTED 10738 Lillian Highway Pensacola, FL 32506 850-453-5488 Tidings The Newsletter of the Friends of Perdido Bay . July/August 2012 Volume 25 Number 4 Jackie Lane - Editor www.friendsofperdidobay.com What A Difference Dilution Makes With the deluge the Pensacola area experienced on June 9th, the drought that was plaguing this area, was finally broken in a big way. Thirteen to 20 inches fell in one day at certain areas close to the bay. Less rain fell in the northern part of the watershed. The few rains we have had this past Spring were not really sufficient to break the year long drought. Before the June 9th rain, the Perdido River was at very low flow. Any type of man-made pollution entering Perdido Bay would not get sufficient dilution and toxic substances (what ever they are) would increase in the bay. This is especially true of paper mill effluent from International Paper, which during times of low flow of the Perdido River, can constitute one-fifth of the flow of the Perdido River. Because of the very concentrated pollution of paper mill effluent, especially high levels of organic chemicals and organic nitrogen, paper mill effluent needs to be greatly diluted in order not to cause harm. This spring there was a dearth of life in the bay. A 2-liter plastic bottle placed in the upper bay, had no barnacles growing on it after three weeks in the bay.
