The General Land Office (GLO) survey notes (1840-1856) were used to examine the interaction among natural disturbance, vegetation type, and topography in the presettlement forests of the Luce District, an ecological unit of approximately 902 000 ha in the Upper Peninsula of Michigan, U.S.A. The surveyors recorded 104 fire and 126 windthrow incidences covering 3.1 and 2.8% of the total length of the surveyed lines, respectively. The rotation periods over the entire landscape were 480 years for fire and 541 years for windthrow, but these varied with vegetation type and topographic position. Fire occurred more frequently on southerly aspects and at elevations where pinelands were concentrated. The density of windthrow events increased with elevation and slope, with the highest occurrence on westerly aspects. Based on the estimated rotation periods, we calculated that 7.5, 24.4, and 68.1% of the presettlement forest were in the stand initiation, stem exclusion, and old forest (including both understory reinitiation and old growth) stages, respectively. Pinelands and mixed conifers were the major components in both the stand initiation (34.5 and 31.1%) and the stem exclusion stage (20.9 and 39.8%), while mixed conifers (39.3%) and northern hardwoods (34.7%) were the major old-forest cover types. The diverse mosaic of various successional stages generated by natural disturbance suggests a "shifting-mosaic" landscape in this region.

ABSTRACT The Texas General Land Office (GLO) has developed elements of an oil spill decision support system that integrate a trajectory model, a real-time environmental monitoring network, and a customized geographic information system (GIS) application. Through applied research, the GLO is striving to improve the reliability of oil spill trajectory modeling by improving the quality and timeliness of the environmental inputs. A GLO-developed GIS user interface facilitates the quick and efficient production of high-quality maps, to provide spill response managers with timely environmental and other spill-related information.

Texas produces nearly twice and much oil as the next highest producing U.S. state and has approximately 3300 miles of sensitive jurisdictional shoreline boarding the second highest area of our nation's oil production, the Gulf of Mexico. It is home to over 27 operating refineries and hosts 3 of the top 10 busiest ports in the nation. Since 1991, the Texas General Land Office (TGLO) has built an oil spill prevention and response program that is arguably the premier state oil spill program in the nation; one that responds 24/7 to over 600 reported spills per year, certifies, audits and inspects over 600 oil handling facilities, administers an abandoned vessel removal program, an oily bilge facility program, and has an ongoing oil spill R&D program and its own state Scientific Support Coordinator, ensuring that prevention, planning and response activities are state of the science. The TGLO produces the Texas Oil Spill Toolkit, now in its 17th edition, which is a spill planning and response resource for the western Gulf of Mexico, and houses a collection of plans and documents in a single, easy to use online/off-line .html format. Plans include up-to-date Area Committee Plans (ACP) and pre-planning documents, all aligned with the National Response Framework (NRF). Included are Regional Response Team VI (RRT) documents and guidance, pre-authorization plans and mapping for alternative spill response, Priority Protection Areas (PPA), Environmental Sensitivity Index Maps (ESI), and site specific Geographic Response Plans (GRP). This paper describes the conception, history and evolution of the building and operation of a state response organization in an era of “less government”.

ABSTRACT Trajectory modeling is one of the few tools that allow spill managers to get ahead of an oil spill. To that end, the Texas General Land Office is committed to maintaining and improving the Texas Automated Buoy System (TABS) and its associated modeling efforts to ensure a reliable source of accurate, up-to-date information on currents along the Texas coast. As the nation embarks on the development of an Integrated Ocean Observing System (IOOS), TABS will be an active participant as a foundational regional component to the national backbone of ocean observations. The lessons-learned from TABS’ ten years of spill response operations will provide a valuable roadmap for the operators of new ocean observing systems to ensure that they understand and meet the unique needs of the oil spill response community. This paper describes the circumstances which led to the creation of TABS; the unique, spill response-driven philosophy behind the development and operation of the system; lessons-learned and the resulting modifications to the system; examples of TABS’ service; new TABS forecasting models and real time analysis tools; and the future direction of TABS in the context of a national Integrated Ocean Observing System.
