Integration of field-based analysis of plant community dynamics with quantitative analysis of landscape change in the Ray Roberts Lake area, 1987-1997
… and 1997. Landscape analyses were performed with FRAGSTATS*ARC using classified SPOT satellite imagery for 1987 and 1997. Although the methodology developed in this work was exploratory, it was found that characterizing the dynamics of major plant communities in the study area produced a more …

Analysis of the One-Horned Rhinoceros (Rhinoceros Unicornis) Habitat in the Royal Chitwan National Park, Nepal.
… with habitat were determined through the use of FRAGSTATS.

A multi-temporal image analysis of habitat modification in the Coastal Watershed, NH
… performed equally well to the more prevalent FRAGSTATS program in creating a predictive model from fragmentation metrics. However, the advantage of PolyFrag over FRAGSTATS is that it creates a fragmentation map in addition to the patch, class, and landscape metrics. Interestingly, both …

Landscape pattern and blister rust infection in whitebark pine (Pinus albicaulis) at alpine treeline, Northern Rocky Mountains, U.S.A.
… area, proximity and contagion were generated in FRAGSTATS software and ArcGIS. Spearman's rank correlation analysis found significant correlations between tree island patch size, patch perimeter, and percent of landscape and blister rust infection intensity at both study sites. These findings …

Predicting favorable habitat for bobcats (Lynx rufus) in Iowa
… of bobcats. I used the programs ArcGIS and FRAGSTATS to calculate landscape composition and configuration from publicly available sources including landcover, census, road, hydrologic, and elevation data. I constructed classification and regression tree (CART) models to identify important …

Assessing the Influence of Landscape Characteristics on Bat Fatalities at South Texas Wind Energy Facilities
… (n = 1), and unknown spp. (n = 113). I used Fragstats and ArcGIS Pro to acquire landscape metrics at the two facilities and among the 100 wind turbines at each facility at multiple scales (100 m, 500 m, 1 km, 5 km, and 25 km). Landscape characteristics included landcover types such as barren, …

Up an Urban Creek: The Role of Development Patterns in Stream Health
… the riparian area (100 m) were calculated using Fragstats v4 and correlated with stream BIBI score and the metrics that comprise the score. I assess the correlations between infrastructure intensity (road density, number of road crossings, and number of stormwater outfalls) and these response …

Large-scale habitat relationships of neotropical migratory birds
… of each site from Quantico’s GIS database using FRAGSTATS. Landscape patches were defined using 2 different classification schemes to determine if both SAF cover type and generalized habitat classifications could be used to determine which large-scale habitat elements influence bird species and …

Predicting habitat suitability for American woodcock and landscape-level assessment of habitat in West Virginia
… the Multi-Resolution Land Cover database and FRAGSTATS spatial analysis program. Logistic regression was used to quantify relationships between woodcock use sites and available habitat. Standard reclassification statistics were used to evaluate modeling efficiency and model results were …

Comparative assessment of flood resilience in urban and rural environments: a case study of Chennai City and Wardha River Sub-basin, India
… analysis using machine learning and the FRAGSTATS programme reveals substantial forest loss and habitat degradation between 2010 and 2025, compromising ecological connectivity and increasing flood risks. Hypothetical scenarios project further increases in runoff under continued …

Relationship of Ruffed Grouse Home Range Size and Movement to Landscape Characteristics in Southwestern Virginia
… types. Landscape metrics were calculated using FRAGSTATS/ARC, and multiple regression was used to relate changes in home range size and movement to these metrics. I used Wilcoxon signed-rank tests to compare the values of landscape metrics calculated for each home range to those calculated for …

Future Lyme Disease Risk in the Southeastern United States Based on Projected Land Cover
… landscape configurations were analyzed using FRAGSTATS 4.2. Significant variables established in previous research were used to develop a spatial Poisson regression model to project Lyme disease incidence for each decade to the year 2100. Results indicated that potential land cover suitability …

Species-Habitat Relationships for the Breeding Birds of a Longleaf Pine Ecosystem
… a GIS database and the spatial analysis program FRAGSTATS. I then used logistic regression to determine which microhabitat and landscape variables were associated with the probability of occurrence for each species and which spatial scale was of greater relative importance to a species' …

Evaluating Population-Habitat Relationships of Forest Breeding Birds at Multiple Spatial and Temporal Scales Using Forest Inventory and Analysis Data
… landscape structure from 1992 NLCD imagery using Fragstats within each buffer size. I developed predictive models relating spatial variations in bird occupancy and abundance to changes in forest and landscape structure using logistic regression and classification and regression trees (CART). …
