A GIS (Geographical Information System) was developed to test automated methods to produce maps of avian distribution and habitat suitability for several species in a mixed habitat area of Northeastern Kansas.
The Multispectral Scanner (MSS) from Landsat 4, and Thematic Mapper (TM) from Landsat 5 were used to capture digital images. This study used blue, green, red, reflected infrared, and thermal infrared images.
Landcover classifications were generated by TM imagery, and not only included 7 habitat types (mesic forest, xeric forest, rangeland, old field, bare ground, water, cropland), but also included spatial characteristics (i.e. minimal patch size, distance to edge).
Birds were censused in 1984 and 1985 in a variety of habitats by the circular point method, and the proportion of habitats in which they were observed was recorded. Map accuracy was high (96 - 98%) for all habitats except the rangeland (93%) and old field (75%) habitats (Which are hard to define; How old must it be to be old?)
There was usually a gradient between the rangeland and old field habitats.
Using the habitat data and the bird census data, the probability of encountering each species in different habitats was mapped. The spatial differences within the habitats were also mapped (Red-eyed vireos prefer mesic forest that is not near the edge, while White-breasted nuthatch prefers all forests).
Maps that represented species density were also produced, and rough population estimates were made. It was concluded that avian distribution maps can be produced by satellite imagery and GIS if habitat characteristics that are critical to the species can be detected by the imagery.
