This project demonstrates the construction of a land planning geographic information system (GIS) for Tarrant County, and explores how the technology could be used to select sites for a county wide open space preservation plan. As Texas' Tarrant County continues to undergo rapid change due to growth and expansion, the need for proactive, resourceful community planning is greater than ever. One crucial issue facing the region is how to preserve open areas that serve the county's citizens' ecological, recreational, cultural and economic needs. In order to assess how much open space is needed and which sites should be considered for special attention, large amounts of varied spatial information must be analyzed. The answer to effectively dealing with such data sets is a geographic information system (GIS) that stores all pertinent data digitally and allows for its manipulation through use of a computer software package. This project demonstrates the construction of a land planning GIS for Tarrant County, and explores how the technology could be used to select sites for a county wide open space preservation plan.

The primary objective of this study is to describe the life history of Camelobaetidius mexicanus living in Honey Creek in south central Oklahoma. Specific objectives were to determine emergence phenology and behavior, describe nupital flight and female oviposition, measure subimaginal and imaginal life spans, examine egg morphology and time to hatching, describe larval microdistribution, analyze gut contents and to determine voltinism from nymphal head capsule widths and adult emergence.
