Environmental Analysis of Environmentally Sensitive Lands for MEDIATION, Litigation and Condemnation Support A large land tract was under threat of condemnation for its environmental value. Various state, federal, and nongovernmental organizations had represented the land as being of particular value due to a combination of threatened and endangered species said to be occupying the land, as well as the presence of certain water bodies and their associated quality. This aggregation of values and diversity was said to limit the development value of the lands and to enhance their environmental value. Remote sensing, photointerpretation techniques and groundtruthing techniques utilizing Global Positioning System were used to specifically locate the points of occurrence of species of interest. This increase in positional accuracy and characterization allowed a higher degree of association of species with ecological niches that were narrow and specific to each species. Print-outs of these locations on large scale aerial maps showed that the assumed area wide occurrence patterns typically shown on environmental maps were misleading. As a consequence of the foregoing, it was obvious that a regulatory approach rather than a taking would be adequate to protect and presumed public interest in the species and their location of occurrence patterns. The combination of techniques were complemented by the use of base stations for increased positional accuracy, bar code readers with issue specific dictionaries for efficient field data collection, downloading at night and provision of information to the decision-making group on a 24 hour cycle from the time of collection to the time of delivery for final usage. The team members were located in offices over 1,000 miles apart. The field location was also separated from any office location. Network data transmittals and communications allowed routine communications and transmittals to be maintained. This combination of office, field and temporary field office adapted techniques allowed rapid, dissemination of accurately positioned field data on a variety of species and factors associated with occurrence and significance to be used by all parties in a communication context that facilitated communication and negotiation processes that preceded the condemnation proceedings.
