Abstract:

This dissertation focuses on detecting and tracking small objects in complex backgrounds and on classifying ultra-sound fetal movement signals. The first part of this dissertation focuses on detecting and tracking laser spots which are small objects in a video frames. Many factors make this particular problem extremely challenging. Examples include, irregular shapes, intensity variations, color variations, speckle noise, obstacles, and background complexity. The new method developed combines the advantages of pyramid Lucas-Kanade (PLK) optical flow and optimal recursive Bayesian filters for detection and tracking. The detection and tracking results of the developed method are compared with the Kalman filter, extended Kalman filter, unscented Kalman filter, and the particle filter. It is shown that the new method yields better results. Monitoring fetal movements is crucial for the early detection of abnormalities in the fetus. The second part of this dissertation focuses on segmenting and classifying fetal movements which are aquired using six ultra-sound sensors strapped onto the stomachs of pregnant women. The goal is to classify the signals into two categories: general and startle. Segmentation is conducted using a signal-energy based algorithm and the signals are classified using features extracted from the segmented signals. Three supervised classifiers, the k nearest neighbor, nearest mean, and a support vector machine, are implemented and their performances are compared. The results show that the method developed is able to effectively classify the dichotomous signals.

Abstract:

Analysis of the waveforms obtained from the umbilical artery using Doppler ultrasound has been claimed in a number of recent reports to be a highly specific method of identifying babies with intrauterine growth retardation. Because of the morbidity and mortality associated with this condition it was important to evaluate the validity of those claims before introducing the method into obstetric practise. The work in this thesis was carried out in four parts. Firstly the technique was found to be reproducible with small intra and inter-observer errors. Secondly, possible influencing factors were studied, and it was found that the fetal heart rate and fetal breathing movements have a significant effect on the waveform. Thirdly, a longitudinal study of 50 healthy women with normal pregnancies was performed to define the normal range of A/B ratios (the principle method of analysis of the waveforms was the A/B ratio: ratio of peak systolic to end-diastolic frequency). Finally, Doppler ultrasound was performed in 205 women with high risk pregnancies, and results were compared to the normal reference data. When high risk cases with abnormal Doppler results (A/B ratio > 95th centile) were compared with high risk cases with normal Doppler results (A/B ratio < 95th centile) the Doppler abnormal group were found to have a significantly increased incidence of preterm delivery, operative delivery, late fetal heart rate decelerations in labour, increased admission to the special care baby unit, and increased neonatal morbidity. Although an abnormal Doppler result was associated with small for gestational age in 61% of cases, only 41% of cases of small for gestational age had abnormal Doppler results. The conclusion from this thesis is that Doppler flow velocity waveform analysis, although lacking the previously claimed diagnostic precision of detecting intrauterine growth retardation, could contribute to fetal management by identifying babies at high risk of intrapartum complications.

Abstract:

The condition of the fetus during labour is inferred from the continuous plot of fetal heart rate and uterine contractions (cardiotocogram, CTG). This can be _ difficult to interpret which results in both unnecessary intervention and a failure to intervene when necessary causing potentially preventable neurological damage and mortality. Conventional computing approaches have not been successful in addressing these problems. This is perhaps because the correct interpretation of fetal condition requires physiological knowledge, considerable practical experience and knowledge of the specific patient. The work described in this thesis is concerned with the investigation of artificial intelligence techniques to assist in the interpretation of fetal condition and advise on labour management. A fundamental investigation examined the performance of five types of scalp electrodes for obtaining the fetal electrocardiogram (ECG), from which heart rate is derived, and examined the factors which hamper fetal ECG data acquisition. New methods were developed to classify the important features from the CTG and included an investigation using neural networks. Other CTG features were classified using novel numerical algorithms developed closely with experts. An expert system, guided by a database of rules obtained from experts, was used to process and interpret changes in the CTG features by taking account of patient specific information. This hybrid approach was adopted to improve performance and reliability. After two internal evaluations had found the system obtained a performance comparable with local experts, an extensive external validation was undertaken. This study involved 17 experts from 16 leading centres within the UK. Each expert and the system reviewed 50 cases twice, at least one month apart which contained those considered most difficult to interpret selected from a database of 2400 high risk labours. A novel method was developed to present all the relevant clinical information in a way which approximated the clinical situation. The reviewers scored each 15 minutes of recording according to the concern they had for the fetus and the management they considered appropriate. In this respect, this is the first reported study to examine the performance of expert obstetricians in the management of labour. A new method was derived to measure the agreement between the scores obtained and is applicable to other areas where it is required to measure the similarity between time related sequences. This study found that the experts agreed well and were consistent in their management of the cases. The system was indistinguishable from the experts, except it was more consistent, even when used by an engineer with little knowledge of labour management. This study has shown that expertise in fetal monitoring is achievable in which case the current evidence suggests that this is not being adequately transferred to clinicians. The challenge remains to formulate a method to effectively transfer knowledge to the labour ward and thereby address the real and practical problems which face fetal monitoring today. This study demonstrates that intelligent systems could provide the vehicle to achieve this. I dedicate this work to the memory of my father, Bradley Kenneth Keith with a hope that he always believed it possible. I know he would have had some interesting comments to make and I sadly miss the opportunity of discussing them with him. I also dedicate this work to my mother for always being there, and to my wife Michelle for her unwavering support, patience and most of all her encouragement throughout this work.

Full text

Abstract:

Choledochal cysts are a core pathology in pediatric surgery, affecting 1/100,000 live births in the western world, and 1/13,000 in eastern asia. These cysts are classified by the Todani classification, types I-V, in respect to their location and underlying pathophysiology. Infants and children presenting with stigmata of biliary disease should undergo evaluation for choledocal cyst. Workup includes axial imaging, ultrasonography, and laboratory investigation. A liver biopsy is necessary in neonates and newborns to rule out cystic biliary atresia, which would require further evaluation and management. Large choledochal cysts may be visualized on prenatal ultrasound, and warrant referral to a fetal care center for postnatal work up and monitoring. Management of choledochal cysts is dependent on the anatomic variant and spans from ERCP with sphincterotomy, to cyst excision with ductal and alimentary tract reconstruction. Type V choledochal cysts may require liver transplantation. Long term follow up is required due to an enhanced risk of future malignancy, even after resection.

Abstract:

Using treated wastewater (TWW) for crop irrigation represents an important opportunity for ensuring adequate food production in light of growing freshwater scarcity worldwide. However, the environmentally sustainable approach of using TWW for irrigation can lead to contamination of produce with fecal pathogens that may remain in treated water. The overall goal of this research was to evaluate the correlation between the presence of fecal indicator bacteria (FIB) and that of a suite of human pathogens in TWW, the irrigated soil, and crops. Field experiments were conducted to compare secondary and tertiary TWW with dechlorinated tap water for irrigation of tomatoes, a typical commercial crop, in Israel, a semi-arid country. Human pathogens including bacteria (Salmonella), protozoa (Cryptosporidiumand Giardia), and viruses (Adenovirus [AV Types A, B, C & 40/41] and Enterovirus [EV71 subtypes]) were monitored in two field trials using a combination of microscopic, cultivation-based, and molecular (qPCR) techniques. Results from the field trials indicate that microbial contamination on the surface of tomatoes did not appear to be associated with the source of irrigated waters; FIB contamination was not statistically different on tomatoes irrigated with TWW as compared to tomatoes irrigated with potable water. In fact, Indicator bacteria testing did not predict the presence of pathogens in any of the matrices tested. High concentrations of FIB were detected in water and on tomato surfaces from all irrigation treatment schemes, while pathogen contamination on tomato surfaces (Cryptosporidiumand Salmonella) was only detected on crops irrigated with TWW. These results suggest that regular monitoring for pathogens should take place to accurately detect presence of harmful microorganisms that could threaten consumer safety. A notable result from our study is that the large numbers of FIB in the water did not appear to lead to FIB accumulation in the soil. With the exception of two samples, E. coli that was present at 10³ to 10⁴ cells/100 mL in the water, was not detected in the soil. Other bacterial targets associated with the enteric environment (e. g., Proteusspp.) as well as protozoal pathogens were detected in the TWW, but not in the soil. These findings suggest that significant microbial transfer to the soil from TWW did not occur in this study. The pattern of FIB contamination on the surfaces of tomatoes was the same for all treatment types, and showed a temporal effect with more contamination detected as the duration of the field trial increased. An important observation revealed that water quality dramatically deteriorated between the time of its release from the wastewater treatment plant and the time it was utilized for irrigation, highlighting the importance of performing water quality testing throughout the growing season at the cultivation site.

To evaluate the direct effect of monochromatic green light on cultured embryonic and adult myoblasts. The overall purpose of this study was to investigate the effect of monochromatic light stimuli during incubation period of broilers on muscle development and satellite cell myogenesis. Based on previous studies (Halevy et al., 1998; Rozenboim et al., 1999) that demonstrated the positive effects of green-light illumination on body and muscle growth, we hypothesized that monochromatic light illumination accelerates embryo and muscle development and subsequently enhances muscle growth and meat production. Thus, further decreases management costs. Under the cooperation of the laboratories at the Hebrew University of Jerusalem and University of Washington we have conducted the following: 1. We have established the critical stage for exposure to green monochromatic light which has the maximal effect on body and muscle growth (Objective A). We report that embryonic day 5 is optimal for starting illumination. The optimal regime of lighting that will eliminate possible heat effects was evaluated by monitoring egg core temperature at various illumination periods. We found that intermitted lighting (15 min. on; 15 min. off) is optimal to avoid heat effects. 2. We have evaluated in detail gross changes in embryo development profile associated to green light stimuli vs. darkness. In addition, we have investigated the stimulatory effect of light combinations during embryo and post-hatch periods on body and muscle growth (Objective B,D). 3. We have studied the expression profile of muscle regulatory proteins during chicken muscle cell differentiation in cultures using newly developed antibodies. This study paved the way for analyzing the expression of these proteins in our photo stimulation experiments (Objective C). 4. We have studied the pattern ofPax7 expression during myogenesis in the posthatch chicken. Experimental chick pectoralis muscles as well adult myoblast cultures were used in this study and the results led us to propose a novel model for satellite cell differentiation and renewal. 5. The effects of monochromatic green light illumination during embryogenesis have been studied. These studies focused on fetal myoblast and satellite cell proliferation and differentiation at pre- and posthatch periods and on the effects on the expression of muscle regulatory proteins which are involved in these processes. In addition, we have analyzed the effect of photo stimulation in the embryo on myofiber development at early posthatch (Objective C). 6. In follow the reviewers' comments we have not conducted Objective E. The information gathered from these studies is of utmost importance both, for understanding the molecular basis of muscle development in the posthatch chicks and for applied approach for future broiler management. Therefore, the information could be beneficial to agriculture in the short term on the one hand and to future studies on chick muscle development in the embryo and posthatch on the other hand.

Abstract:

Water quality monitoring in National Park Service units of the Northern Colorado Plateau Network (NCPN) is made possible through partnerships between the National Park Service Inventory & Monitoring Division, individual park units, the U.S. Geological Survey, and the Utah Department of Environmental Quality. This report evaluates water quality data from site visits at 42 different locations within and around eight park units in Utah and Colorado from October 1, 2018 through September 30, 2022. Data are compared to state water quality standards for the purpose of providing information to park managers about potential water quality problems. Parks included for evaluation are Arches National Park (NP), Bryce Canyon NP, Canyonlands NP, Capitol Reef NP, Dinosaur National Monument (NM), Hovenweep NM, Timpanogos Cave NM, and Zion NP. Evaluation of water quality parameters relative to state water quality standards indicated that 21,644 (96.8%) of the 22,356 total designated beneficial-use evaluations completed for the period covered in this report met state water quality standards. The most common parameters that did not meet a standard include fecal indicator bacteria (Escherichia coli), water temperature, and total dissolved solids (TDS). While TDS can be an indicator of pollution, in NCPN parks, it mostly occurs downstream of rock outcrops that naturally increase TDS in streams. Phosphorus concentrations were often greater than acceptable thresholds but were rarely associated with indicators of impairment such as algal blooms, fish kills, or low dissolved oxygen. Sites monitored in Arches NP, Bryce Canyon NP, Capitol Reef NP, Dinosaur NM, Hovenweep NM, and Zion NP all had occurrences when fecal indicator bacteria concentrations were greater than associated state standards. State-coordinated plans to reduce waste contamination are in place for the North Fork Virgin River (Zion NP) and the Fremont River (Capitol Reef NP). The plans have resulted in a decrease in the number of chronic and acute standard violations at Zion. Elevated water temperatures occurred at sites in Canyonlands NP, Capitol Reef NP, and Zion NP. Water temperature is strongly correlated with air temperature in surface waters across the Colorado Plateau. Additional issues of management concern include low dissolved oxygen in Salt Wash at Wolfe Ranch (Arches NP) and Square Tower Spring (Hovenweep NM), as well as selenium in the Colorado River (Arches NP and Canyonlands NP). State-coordinated plans to reduce selenium concentrations in the Upper Colorado River basin are in place.

Abstract:

Parks within the Southeast Coast Network (SECN) host a diverse assemblage of plants and terrestrial vegetation communities. Vegetation communities are dynamic entities whose species composition, abundance, distribution, and structure are influenced by environmental factors and impacted over time by natural and anthropogenic disturbances. Determining trends in vegetation communities over time and identifying plant stressors is vital to understanding the ecological health of terrestrial ecosystems within SECN parks. Like most barrier islands along the southeastern coast, the vegetation communities along Cape Lookout National Seashore range from open beach and foredune grasslands on the ocean-facing side to tidal marshes on the sound-facing side. Between is a mixture of interdune swales, backdunes, and enclosed wetlands. Open upland vegetation is found on foredunes and occasional backdunes within the seashore. Cape Lookout National Seashore ecosystems are subjected to high frequencies of storm-, wind-, tide-, and wave-driven processes. Historic and current vegetation composition and structure are largely a result of these highly dynamic processes. Current vegetation patterns and processes across the Outer Banks are impacted and will continue to be impacted by rising sea-levels. Vegetation communities are vulnerable to overwash, which moves sand from the island?s ocean-side to the sound-side, brought on by more frequent and higher intensity storms. In 2019, Hurricane Dorian produced significant storm surge from the sound-side that overwashed the island and deposited sand into the ocean. Sand was scoured out from over 54 major cuts in the island, creating current ponds that are in various stages of succession. 2022 marked the first year of conducting this monitoring effort at Cape Lookout National Seashore. Forty-nine vegetation plots were established throughout the park in May and June. Data collected in each plot included species richness across multiple spatial scales, species-specific cover and constancy, species-specific woody stem seedling/sapling counts and adult tree diameter at breast height (DBH), overall tree health, landform, soil, observed disturbance, and woody biomass estimates. Data were stratified across four dominant broadly defined habitats within four park subunits: North Core Banks, South Core Banks, Cape Lookout, and Shackleford Banks. Broadly defined habitats monitored included: Open Upland Vegetation, Upland Forests and Shrublands, Nontidal Wetland Vegetation and Tidal Wetlands. One hundred and eighty-six vascular plant taxa were detected during this monitoring effort, including 11 taxa not detected in previous lists. Human-caused disturbances (e.g., historical plowing, shifting fire regimes, and altered hydrology) affecting plant communities within other SECN parks were not observed within these plots during this survey effort. Stunted plant growth was observed on several plots of Shackleford Banks and is likely caused by feral horse grazing. It is unclear from these data if grazing has impacted overall vegetation diversity and structure patterns across the island.

Abstract:

The Southeast Coast Network (SECN) conducts long-term terrestrial vegetation monitoring as part of the NPS Inventory and Monitoring Program. The vegetation community vital sign is one of the primary-tier resources identified by SECN park managers, and monitoring is conducted at 15 network parks (DeVivo et al. 2008). Monitoring plants and their associated communities over time allows for targeted understanding of ecosystems within the SECN geography, which provides managers information about the degree of change within their parks’ natural vegetation. 2021 marks the first year of conducting this monitoring effort at Ocmulgee Mounds National Historical Park (OCMU). Eight vegetation plots were established throughout the park in early May. Data collected in each plot included species richness across multiple spatial scales, species-specific cover and constancy, species-specific woody stem seedling/sapling counts and adult tree (greater than 10 centimeters [3.9 inches {in}]) diameter at breast height (DBH), overall tree health, landform, soil, observed disturbance, and woody biomass (i.e., fuel load) estimates. This report summarizes the baseline (year 1) terrestrial vegetation data collected at Ocmulgee Mounds National Historical Park in 2021. Data were stratified across two dominant broadly defined habitats within the park, Coastal Plain Alluvial Wetlands and Coastal Plain Upland Forests. Noteworthy findings include: 142 vascular plant taxa (species or lower) were observed across eight vegetation plots, including 15 species not previously documented within the park. The most frequently encountered species in each broadly defined habitat included: Coastal Plain Alluvial Wetlands: Chinese privet (Ligustrum sinense), Chinese tallow (Triadica sebifera), Japanese honeysuckle (Lonicera japonica), eastern poison ivy (Toxicodendron radicans var. radicans), and smallspike false nettle (Boehmeria cylindrica). Coastal Plain Upland Forests: sweetgum (Liquidambar styraciflua), muscadine (Muscadinia rotundifolia var. rotundifolia), winged elm (Ulmus alata), water oak (Quercus nigra), loblolly pine (Pinus taeda), yaupon (Ilex vomitoria), Japanese honeysuckle, American beautyberry (Callicarpa americana), ebony spleenwort (Asplenium platyneuron), and multiple species of woody vines. Eleven non-native species invasive (Category 1 or Category 2) by the Georgia Exotic Pest Plant Council (GA-EPPC 2023) were encountered within the park during this monitoring effort. Three of these species—Chinese privet, Chinese tallow, and Japanese honeysuckle—were among the most frequent and abundant of all species observed within Coastal Plain Alluvial Wetland plots. There were no observations of vascular plant species listed as rare and tracked by the Georgia Department of Natural Resources (GADNR 2023) within these monitoring plots. Sweetgum, red maple (Acer rubrum), swamp tupelo (Nyssa biflora), and Chinese tallow were the most dominant species within the tree stratum of Coastal Plain Alluvial Wetland sites; water oak, loblolly pine, and sweetgum were the most dominant species of Coastal Plain Upland Forests. There were very few observable disturbances to natural and semi-natural vegetation communities documented during this monitoring effort, including very little to no impact of browsing by white-tailed deer, rooting by feral hogs, or presence of diseased or dying trees. The two most pronounced threats to native vegetation on the park are (1) the high prevalence of non-native, invasive plant species (particular within alluvial habitat, and (2) the altered hydrology of the park’s alluvial wetlands from conversion of large berms for vehicle and railroad traffic. Long-term monitoring data will aid in understanding how these threats over time impact the park’s forest communities.

Monitoring plants and their associated communities over time allows for targeted understanding of ecosystems within the SECN geography, which provides managers information about the degree of change within their parks’ natural vegetation. 2021 marked the first year of conducting this monitoring effort at Congaree National Park (CONG). Sixty-four vegetation plots were established throughout the park from May through August. Data collected in each plot included species richness across multiple spatial scales, species-specific cover and constancy, species-specific woody stem seedling/sapling counts and adult tree (greater than 10 centimeters [3.9 inches {in}]) diameter at breast height (DBH), overall tree health, landform, soil, observed disturbance, and woody biomass (i.e., fuel load) estimates. This report summarizes the baseline (year 1) terrestrial vegetation data collected at Congaree National Park in 2021. Data were stratified across two dominant broadly defined habitats within the park, Coastal Plain Upland Open Woodlands and Coastal Plain Alluvial Wetlands. Noteworthy findings include: 295 vascular plant taxa (species or lower) were observed across 64 vegetation plots, including 37 species not previously documented within the park. 27 unique species of sedge (Carex sp.) were found across all plots. The most frequently encountered species in each broadly defined habitat included: Coastal Plain Alluvial Wetlands: green ash (Fraxinus pennsylvanica), red maple (Acer rubrum), possumhaw (Ilex decidua), eastern poison ivy (Toxicodendron radicans var. radicans), muscadine (Muscadinia rotundifolia var. rotundifolia) and smallspike false nettle (Boehmeria cylindrica). Coastal Plain Upland Open Woodlands: loblolly pine (Pinus taeda), muscadine, sweetgum (Liquidambar styraciflua), willow oak (Quercus phellos), roundleaf greenbrier (Smilax rotundifolia), and Carolina jessamine (Gelsemium sempervirens). Seven non-native species categorized as invasive (Significant or Severe Threat) by the South Carolina Exotic Pest Plant Council (SCEPPC 2014) were encountered within the park during this monitoring effort. These included sweet autumn virginsbower (Clematis terniflora), Chinese privet (Ligustrum sinense), Japanese honeysuckle (Lonicera japonica), Japanese climbing fern (Lygodium japonicum), Japanese stilt grass (Microstegium vimineum), marsh dew flower (Murdannia keisak), and Chinese wisteria (Wisteria sinensis). Four species listed as rare and tracked by the South Carolina Natural Heritage Program (SCNHP 2023) were encountered during this monitoring effort. These included Cherokee sedge (Carex cherokeensis), ravenfoot sedge (Carex crus-corvi), Santee azalea (Rhododendron eastmanii), and heartleaf nettle (Urtica chamaedryoides). Sweetgum, water tupelo (Nyssa aquatica), green ash, and bald-cypress were the most dominant species within the tree stratum of Coastal Plain Alluvial Wetland sites; loblolly pine was the most dominant species of Coastal Plain Upland Open Woodlands. Feral hog (Sus scrofa) rooting was observed in 73% of the Coastal Plain Alluvial Wetland plots, while 20% of the plots had over 60% damage from rooting behavior. Hog activity was observed throughout the Congaree National Park’s floodplain, but largely absent from sites along the park’s northern boundary with the private hunt club. Based on data collected from eight Coastal Plain Upland Open Woodland plots, the canopy and subcanopy composition and structure of the park’s upland pine woodlands are not in a condition to maintain fire-dependency and thus promote healthy and sustainable longleaf pine woodlands. Densities of loblolly pine in the canopy and sweetgum in the sapling stratum are elevated. However, with continued fire and fire surrogate treatments to these upland units, thriving longleaf pine woodlands can be achieved. All plots are scheduled to be resampled during the summer of 2025.

Abstract:

The Southeast Coast Network (SECN) conducts long-term terrestrial vegetation monitoring as part of the nationwide Inventory and Monitoring Program of the National Park Service (NPS). The vegetation community vital sign is one of the primary-tier resources identified by SECN park managers, and it is currently conducted at 15 network parks (DeVivo et al. 2008). Monitoring plants and their associated communities over time allows for targeted understanding of ecosystems within the SECN geography, which provides managers information about the degree of change within their parks’ natural vegetation. 2020 marks the first year of conducting this monitoring effort at Cumberland Island National Seashore (CUIS). Fifty-six vegetation plots were established throughout the park from May through July. Data collected in each plot included species richness across multiple spatial scales, species-specific cover and constancy, species-specific woody stem seedling/sapling counts and adult tree (greater than 10 centimeters [3.9 inches {in}]) diameter at breast height (DBH), overall tree health, landform, soil, observed disturbance, and woody biomass (i.e., fuel load) estimates. This report summarizes the baseline (year 1) terrestrial vegetation data collected at Cumberland Island National Seashore in 2020. Data were stratified across three dominant broadly defined habitats within the park, including Coastal Plain Upland Open Woodlands, Maritime Open Upland Grasslands, and Maritime Upland Forests and Shrublands. Noteworthy findings include: 213 vascular plant taxa (species or lower) were observed across 56 vegetation plots, including 12 species not previously documented within the park. The most frequently encountered species in each broadly defined habitat included: Coastal Plain Upland Open Woodlands: longleaf + pond pine (Pinus palustris; P. serotina), redbay (Persea borbonia), saw palmetto (Serenoa repens), wax-myrtle (Morella cerifera), deerberry (Vaccinium stamineum), variable panicgrass (Dichanthelium commutatum), and hemlock rosette grass (Dichanthelium portoricense). Maritime Open Upland Grasslands: wax-myrtle, saw greenbrier (Smilax auriculata), sea oats (Uniola paniculata), and other forbs and graminoids. Maritime Upland Forests and Shrublands: live oak (Quercus virginiana), redbay, saw palmetto, muscadine (Muscadinia rotundifolia), and Spanish moss (Tillandsia usneoides) Two non-native species, Chinaberry (Melia azedarach) and bahiagrass (Paspalum notatum), categorized as invasive by the Georgia Exotic Pest Plant Council (GA-EPPC 2018) were encountered in four different Maritime Upland Forest and Shrubland plots during this monitoring effort. Six vascular plant species listed as rare and tracked by the Georgia Department of Natural Resources (GADNR 2022) were observed in these monitoring plots, including the state listed “Rare” Florida swampprivet (Forestiera segregata var. segregata) and sandywoods sedge (Carex dasycarpa) and the “Unusual” green fly orchid (Epidendrum conopseum). Longleaf and pond pine were the most dominant species within the tree stratum of Coastal Plain Upland Open Woodland habitat types; live oak was the most dominant species of Maritime Upland Forest and Shrubland types. Saw palmetto and rusty staggerbush (Lyonia ferruginea) dominated the sapling stratum within Maritime Upland Forest and Shrubland habitat types. Of the 20 tree-sized redbay trees measured during this monitoring effort only three were living and these were observed with severely declining vigor, indicating the prevalence and recent historical impact of laurel wilt disease (LWD) across the island’s maritime forest ecosystems. There was an unexpectedly low abundance of sweet grass (Muhlenbergia sericea) and saltmeadow cordgrass (Spartina patens) within interdune swale plots of Maritime Open Upland habitats on the island, which could be a result of grazing activity by feral horses. Live oak is the dominant tree-sized species across...
