Revision History for Open-File Report 2019–1071 By Sara L. Zeigler, Emily J. Sturdivant, and Benjamin T. Gutierrez Evaluating Barrier Island Characteristics and Piping Plover (Charadius melodus) Habitat Availability Along the U.S. Atlantic Coast—Geospatial Approaches and Methodology --------------------------------------------- Posted online July 25,2019 --------------------------------------------- Revised and reposted October 23, 2019 The text version was modified. Entries 1, 2, and 3 on page 14 under "Anthropogenic Modification" were revised. Under "1. Nourishment," the text was revised from: 1. Nourishment: A numerical code specifying if there was (a) occasional beach nourishment (>1 year frequency; value=1), (b) frequent beach nourishment (=1 year frequency; value=2), or (c) no record of beach nourishment at a site (value=3). Reports by Rice (2015a, b) were consulted to determine nourishment histories for each site. to: 1. Nourishment: A numerical code specifying if there was (a) no record of beach nourishment at a site (value=111), (b) occasional beach nourishment (has occurred at least once in recent decades; value=222), or (c) frequent beach nourishment (<=1–2-year frequency; value=333). Reports by Rice (2015a, b) were consulted to determine nourishment histories for each site. Under "2. Construction," the text was revised from: 2. Construction: A numerical code specifying if there were (a) no constructed features (value=1), (b) soft shoreline stabilization strategies (for example, constructed dunes or berms, sand fencing, geotubes; value=2), (c) hard structures (for example, rip-rap, seawalls, groins, jetties; value=3), or (d) both soft and hard strategies (value=4). to: 2. Construction: A numerical code specifying if there were (a) no constructed features (value=111), (b) soft shoreline stabilization strategies (for example, constructed dunes or berms, sand fencing, geotubes; value=222), (c) hard structures (for example, rip-rap, seawalls, groins, jetties; value=333), or (d) both soft and hard strategies (value=444). Under "3. Development," the text was revised from: 3. Development: A numerical code specifying the level of development present along a transect. Examples of each definition are provided in figure 6. The level of development could include (a) none, where no development was present (value=1; fig. 6A); (b) light, which includes the presence of a road, paved or unpaved, and the occasional structure (for example, a house; value=2; fig. 6B); (c) moderate, which includes the presence of more extensive roads and (or) buildings along a transect (value=3; fig. 6C); or (d) heavy, which indicates a high density of paved surfaces, houses, or buildings along a transect (value=4; fig. 6D). to: 3. Development: A numerical code specifying the level of development present along a transect. Examples of each definition are provided in figure 6. The level of development could include (a) none, where no development was present (value=111; fig. 6A); (b) light, which includes the presence of a road, paved or unpaved, and the occasional structure (for example, a house; value=222; fig. 6B); (c) moderate, which includes the presence of more extensive roads and (or) buildings along a transect (value=333; fig. 6C); or (d) heavy, which indicates a high density of paved surfaces, houses, or buildings along a transect (value=444; fig. 6D). On page 16, in table 4 under "Anthropogenic modification," the text was revised. Under "Anthropogentic modification—Nourishment," the text entries were revised from: Occasional (1) Nourishment occurs over periods longer than every year (for example, nourishment occurs every 2 to 3 years). Frequent (2) Nourishment over periods of 1 year or less (for example, nourishment occurs twice every year). None (3) Nourishment was not conducted at that location in recent history. to: None (111) Nourishment was not conducted at that location in recent history. Occasional (222) Nourishment has occurred at least once in recent decades Frequent (333) Nourishment over periods of 1–2 years or less (for example, nourishment occurs twice every year). Under "Anthropogentic modification—Construction," the text entries were revised from: No features (1) No erosion control measures are present. Soft (2) Soft erosion control measures (for example, constructed dunes or berms) are present. Hard (3) Hard erosion control measures (for example, seawalls, groins, jetties) are present. Hard and soft (4) Both hard and soft erosion control measures are present. to: No features (111) No erosion control measures are present. Soft (222) Soft erosion control measures (for example, constructed dunes or berms) are present. Hard (333) Hard erosion control measures (for example, seawalls, groins, jetties) are present. Hard and Soft (444) Both hard and soft erosion control measures are present. Under "Anthropogentic modification—Development," the text entries were revised from: None (1) No human development is present (fig. 6A). Light (2) Limited human development is present (for example, a paved or unpaved road, an occasional house; fig. 6B). Moderate (3) More extensive human development is present (for example, paved roads, houses; fig. 6C). Heavy (4) A high density of buildings, roads, and paved surfaces are present (fig. 6D). to: None (111) No human development is present (fig. 6A). Light (222) Limited human development is present (for example, a paved or unpaved road, an occasional house; fig. 6B). Moderate (333) More extensive human development is present (for example, paved roads, houses; fig. 6C). Heavy (444) A high density of buildings, roads, and paved surfaces are present (fig. 6D).
