The purpose of this study was to answer the following question: What was the perceived value to planners of incorporating information from ecotourists about their perceived needs in the standard system presently being used to plan interpretation? The Ecotourist Needs Assessment (ETNA) process was proposed as an external needs assessment. To exemplify this process, an instrument called Ecotourist Needs Assessment Instrument (ETNAI) was developed to collect input from ecotourists who visited the Malheur National Wildlife Refuge. A case resulted from the process. The ETNAI case was used to obtain planners' opinions about whether ETNA had value in the context of data collection and inventory in interpretive planning. The ETNAI case included developing and validating the ETNAI and providing a procedure for implementing ETNAI. Upon completion of the ETNAI case, an interview guide was developed and administered to interpretive planners. Interpretive planners were asked how they currently plan interpretation and collect information to decide interpretive topics. Other questions dealt with their feelings regarding the usefulness of the ETNA and the data collected using the ETNA. The interpretive planners described the current system and provided information about the proposed system (ETNA). Currently, decisions involving interpretation are based on three factors: 1) money, 2) mandates/missions, and/or 3) management. The interpretive planner chose outside (external) groups except during a master planning process when the general public provided input. The outside groups included: professionals, the public, and recreation providers. The current methods used to collect information were informal or considered casual. When contrasted with the proposed method, the interpretive planners felt the ETNA had value. This was reflected in their suggestions for use: As an evaluation tool after an interpretive program is given to a specific audience. As a method to assess the interpretive needs of visitors and specific audiences for interpretation. As a technique to access visitors and the public, both general and specific. As a mechanism to collect data at public meetings. As a systematic routine to develop interpretation, to provide feedback for further development, and to evaluate interpretation embedded in the site system. As a method to effectively determine the distribution of funds. / Graduation date: 1993

St. Vincent Island is one of the barrier islands in the Florida panhandle between Apalachicola Bay and the Gulf of Mexico. The St. Vincent National Wildlife Refuge encompasses all 5000 hectares of the island. Archaeological fieldwork in the summer of 2009 included a survey of the entire island and a test unit at one of the island's richest sites. In spring of 2010 a second test unit was excavated at another archaeologically rich site. A total of 16 known sites were investigated and two newly discovered sites recorded. This research combines all these data with information obtained from existing artifact collections and archives, as well as results of a widespread geological survey of the island, in order to characterize the prehistoric archaeological record on the island, which stretches back at least 4000 years or more, to the time of the island's first formation. Subsistence, settlement patterns, site use, and change through time in the human adaptation on St. Vincent are described in relation to the preexisting cultural chronology of the region, especially that of other barrier islands. Settlement from all time periods is concentrated on the north and east shorelines, with not much human use of the island interior until recent historic time. Geological indication of sea level fluctuations on the islands oldest shoreline section, on the northeast tip, is combined with archaeological evidence to suggest responses to rising sea levels.

The purpose of this thesis was to determine the extent of sea level rise (SLR) impact on sea turtle nesting beach habitat on Archie Carr National Wildlife Refuge (NWR) as well as impacts on management strategies. The Archie Carr NWR is of exceptional importance due to the high density of Loggerhead, Leatherback, and Green sea turtles that nest there in the summer months. GIS data provided by the Archie Carr NWR and various SLR scenarios, provided by both the Intergovernmental Panel on Climate Change (IPCC) as well as leading scholars, were used to determine inundation area loss across the Refuge as well as nearby parcels targeted for possible acquisition. Inundation losses for the six scenarios were calculated to be in the 20-25% range. Approximately 26% of current lower priority parcels are reclassified as high priority when integrating this information. Therefore, a significant revision to future acquisition strategies is recommended.

Marine turtles have historically contributed to economic activity through consumptive harvest for food, tools, and decorative objects. Only recently have they begun to benefit humans economically through non-consumptive roles, primarily as a focal point of educational eco-tourism. In recent years, the annual number of turtle walks conducted around the Archie Carr National Wildlife Refuge (ACNWR) has risen. This expansion contributed to a statistically significant increase in attendance from 2,162 in 2001 to 3,047 participants in 2014. I examined the regional economic impacts of marine turtle eco-tourism around the ACNWR using social surveys and an economic impact analysis tool. IMPLAN, an input-output modeling package, has been used in tourism industries around the U.S. since 1992, but this study is the first to use this tool to evaluate the holistic economic effects of marine turtle-based eco-tourism within a selected region. During the 2014 turtle walk season (June through July), surveys were distributed at six different turtle walk locations within Brevard and Indian River Counties, Florida, along the central Florida Atlantic coast. Adults attending the turtle walks (n=2,274) were given time before the educational presentation began to complete a one-page survey. Approximately 93% of turtle walk participants completed surveys. Due to market interactions within this two-county region, turtle walks contributed a minimum of three new jobs and a conservative estimate of almost $250,000 (USD) to the local economy during the two-month turtle walk season. Using financial comparisons and economic impact tools, like IMPLAN, can improve our understanding of the many roles, especially non-consumptive uses, sea turtles have in our communities. This information can be useful in resource management and conservation-based decision making.

Marine turtles exhibit strong fidelity to their nesting beaches, making the conservation of nesting beaches important for ensuring successful sea turtle populations. Conservation of these nesting beaches involves understanding how species interact with the environment and each other, and understanding how environmental change and population growth can affect the suitability of the nesting habitat. The Archie Carr National Wildlife Refuge (ACNWR) is unusual in its high density of sea turtle nesting by two species: green (Chelonia mydas) and loggerhead (Caretta caretta) turtles. The ACNWR in Melbourne Beach, Florida was established in 1991 due to the high density of loggerhead nesting, but in the time since it was established there has been a significant increase in green turtle nesting, from fewer than 50 nests in 1982 to over 15,000 in 2017. With such a high density of these two species in one relatively small area (21 kilometers of beach), the two species may compete for space. This is especially true for green turtles, which disturb large amounts of sand during their nesting process; in 2017, we observed 338 loggerhead clutches disturbed by nesting females during nesting surveys, nearly all of which were disturbed by green turtles. Using observed spatial and temporal nesting patterns for both green turtles and loggerheads on the ACNWR, I examined the effects these species may have on each other's nests now and in the future. Additionally, green turtles and loggerheads nest in different densities along the length of the ACNWR, with green turtles more concentrated in the southern portions of the Refuge. Finally, green turtle nesting begins and peaks approximately one month later on the ACNWR than loggerhead nesting. For each of these metrics, there is both considerable overlap and distinct separation between the two species. By using these metrics in a modeling approach, I estimated the probability of nest disturbance by a subsequently nesting female, ranging from 0 to 0.105, and how these probabilities are predicted to change over time with a growing green turtle population. Evaluating the carrying capacity of this beach is important in the context of habitat disturbance, including climate change and an increase in storm frequency, and informing adaptive management strategies for effective conservation.
