Book The Archie Carr National Wildlife Refuge

Download or read book The Archie Carr National Wildlife Refuge written by Cristina Marie Hall and published by . This book was released on 2018 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each year, sea turtle nesting beaches are lost globally due to coastal development, leaving females with fewer places to lay eggs. To ensure the livelihood of endangered sea turtle species, it is imperative to spread awareness and promote conservation efforts within these locations. The Archie Carr National Wildlife Refuge (ACR), spans 20.5 miles along Florida's Atlantic coastline and hosts the largest nesting population of loggerhead and green sea turtles in the United States. The refuge is uniquely segmented, resulting in the integration of endangered species and ecosystem protection with sustainable tourism development and recreational use. Despite efforts to reduce impacts of coastal development, little research can be found concerning the impacts ecotourism has on Florida's nesting beaches, or whether tourism activities help to improve conservation efforts. Also, while the ACR plays an active role in promoting conservation, little is known about the visitor experience received while visiting the refuge. This paper looks at the effects coastal development has on sea turtle nesting, and the role ecotourism plays in preserving vital nesting beaches. Additionally, this paper will investigate the level of visitor satisfaction achieved, despite conservation regulations implemented within the ACR. To achieve this, threats are identified, global long-term studies are referenced and structured survey and interview results are reviewed. Similarities drawn from the long-term studies will help the reader to better understand how ecotourism not only aided in diminishing the threats that impacted other nesting locations, but will help distinguish the role ecotourism plays in the conservation and protection of sea turtle nesting beaches within the ACR. Survey and interview results help to evaluate both the visitor experience and gauge knowledge of refuge conservation efforts, while gaining expert opinions on the impacts coastal development have on sea turtle nesting beaches within the state of Florida over the past decade.

Book The Effects of Beach Nourishment on Sea Turtle Nesting Densities in Florida

Download or read book The Effects of Beach Nourishment on Sea Turtle Nesting Densities in Florida written by Aubree A. Gallaher and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of the nesting data showed that approximately six of the nourishment events experienced declines in the first year or two post-nourishment, supporting the hypothesis. The remaining seven beaches did not support the hypothesis. Five of the nourishment events that did not support the hypothesis showed no difference in nesting densities compared to the control beaches, and the remaining two nourishment events experienced increases in nesting when compared to the control beach. The analysis of these 13 nourishment events indicates that the nesting sea turtles' responses to nourishment vary based on site-specific conditions. When data are available, nourishment projects should evaluate nesting trends following past nourishments at their particular beach to assist in developing an appropriate strategy for preventing declines in nesting. Due to the potential declines in sea turtle densities that may occur following nourishment, coastal managers should consider methods such as retreat to avoid the need for shoreline stabilization projects.

Book Determining the Impacts of Beach Restoration on Loggerhead Caretta Caretta and Green Turtle Chelonia Mydas Nesting Patterns and Reproductive Success Along Florida s Atlantic Coast

Download or read book Determining the Impacts of Beach Restoration on Loggerhead Caretta Caretta and Green Turtle Chelonia Mydas Nesting Patterns and Reproductive Success Along Florida s Atlantic Coast written by Allison Whitney Hays and published by . This book was released on 2012 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial beach nourishment, the most common method to mitigate coastal erosion in the United States, is also considered the most ecologically friendly alternative for shoreline stabilization. However, this habitat alteration has the potential to impact nesting marine turtles and developing hatchlings. The first objective of this study was to determine how nourishing beaches with two different design templates affects loggerhead (Caretta caretta) and green turtle (Chelonia mydas) nesting success, the ratio of nests to the total number of nests and non-nesting emergences, and reproductive success, the ratio of hatched and emerged hatchlings to the total number of eggs deposited. Two types of restoration designs exist along the southern Brevard County, FL coastline, which supports some of the highest density loggerhead and green turtle nesting worldwide. Since 2005, approximately 35 kilometers of beach have undergone 1) full-scale restoration (typically called nourishment), where sand was added above and below the mean high tide line (2005, 2010) or 2) dune restoration, where sand was placed on the dune (2005, 2006, 2008, 2009). To quantify the effects of these restoration types, we used a Before-After-Control-Impact-Paired Series (BACIPS) model, which tests for significance between the difference in nesting success rates at the impact (engineered) and control sites (natural beach) before and after restoration ([delta]). For loggerheads, there was a significant difference in [delta] after dune restoration during the years of construction (2005, 2006, 2008, and 2009; p[less than]0.001) and one year post-construction (2007; p[less than]0.05 and 2010; p[less than]0.001). After full-scale restoration, there was a significant difference in [delta] during the years of construction (2005 and 2010; p [less than]0.001) and one year post-construction (2006; p[less than]0.001). For green turtles, there was a significant difference in[delta] after dune restoration during two of the four years of construction (2006; p[less than]0.05 and 2008; p[less than]0.01) and one of the two one-year post-construction years (2010; p[less than]0.05). After full-scale restoration, the significant difference in [delta] lasted every season (2005-2010; p[less than]0.001). There were no significant differences in [delta] for loggerhead or green turtle reproductive success rates after either type of restoration. The second objective was to use the different restoration designs to study what beach characteristics function as loggerhead nesting cues to explain why altering the beach decreases nesting success rates. We examined beach elevation and slope, sand moisture content, sand grain size, beach width, and distance traveled. Logistic regression model selection found all variables were important (R2=0.75). Further examination of trends, with each crawl divided into quarters, found beach slope served as a nesting cue. In all study sites except one, when turtles false crawled, the beach flattened out in the final quarter of the crawl. Conversely, in nesting emergences, the final quarter rose at a steeper slope than the previous quarter. Additionally, model selection found variables important in nest site selection were also important in hatching (R2=0.44) and emergence (R2=0.45) success. These results offer new insight into how and why marine turtle nesting patterns change after artificial nourishment, providing information necessary to nourish beaches in a more "turtle-friendly" manner.

Book Beach Restoration in Florida

Download or read book Beach Restoration in Florida written by Mario Jorge Mota and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: High sand compaction restricts gas diffusion between clutch and atmosphere. This accumulates carbon dioxide in the clutch and prevents oxygen from reaching the eggs. This combination of gases is detrimental to sea turtle development and leads to lower hatching and emerging successes. In the second experiment I found that high concentrations of unbound sand calcium carbonate reduced clutch carbon dioxide concentrations during the second half of incubation. This buffering effect maintained incubation gases within safe physiological levels and reduced clutch mortality. However, hatchlings emerging from these nests had significantly smaller body depths, higher packed cell volumes, higher total protein levels, and higher triglycerides. This physiological data indicate these hatchlings were more dehydrated and metabolized more yolk than controls. Their physiological condition worsened after crawling 10 meters, intended to replicate traversing the beach to ocean. Data show that although clutch carbon dioxide levels can be reduced by unbound sand calcium carbonate, high sand compaction has a consistently negative impact on diffusion of oxygen and carbon dioxide molecules. Differences in atmospheric concentrations, diffusion rates, and solubility of oxygen and carbon dioxide molecules, intensify this effect for the latter. Regulation of specific sand characteristics is paramount for beach nourishment projects. Engineers and regulators should incorporate the information emanating from this dissertation into future beach restoration projects because it relates human needs to the consequences beach sand can have on the incubation of loggerhead sea turtles.
