The 'Grossglockner', Austria's highest mountain at 3,789m, is one
of the most important summits of the Eastern Alps - and not only
because it is so important for alpine tourism. At the end of the
18th Century, it had been explored and nobody less than Arch Bishop
Salm-Reiffenscheidt-Krautheim was the first to ascend in 1800.
Today, with more than 5000 ascents per year, it is a very popular
destination for climbers. But even for those who do not want to
climb, the fascination of this mountain is hard to escape. There is
no better way to investigate than from the 'Grossglockner' High
Alpine roads. The road leads across both mountain passes Fuscher
Toerl and Hochtor, crossing the main Alpes from Salzburg to
Carinthia, with turnoffs to the Edelweiss peak and the
Kaiser-Franz-Josef-height. The road as an adventure trip and its
12% ascent has to be well managed. Who would be more capable to
report about all this than Stefan Bogner, the master of the
automobile photo books? With fuel in his blood and a sensitive feel
for history, but also with accelerator and brake, he provides a
portrait of one of the most exciting and most visited Alpine roads.

The purpose of this report is to (1) compare the extent and
duration of the flooded area in isolated wetlands located in three
regional well fields operated by Tampa Bay Water in the northern
Tampa Bay region during a period before and a period after
reductions in the rate of groundwater withdrawals; (2) evaluate the
ability of the flooded area duration integrated over the two
periods to provide evidence of the change in wetland hydrologic
conditions; and (3) discuss the potential use of wetland
flooded-area data to interpret long-term wetland vegetation
monitoring data.
The U.S. Geological Survey Puget Sound Ecosystem Portfolio Model is
a decisions-support tool that uses scenarios to evaluate where,
when, and to what extend future population growth, urban growth,
and shoreline development may threaten the Puget Sound nearshore
environment.
Threshold concepts are used in research and management of
ecological systems to describe and interpret abrupt and persistent
reorganization of ecosystem properties (Walker and Meyers, 2004;
Groffman and others, 2006). Abrupt change, referred to as a
threshold crossing, and the progression of reorganization can be
triggered by one or more interactive disturbances such as land-use
activities and climatic events (Paine and others, 1998). Threshold
crossings occur when feedback mechanisms that typically absorb
forces of change are replaced with those that promote development
of alternative equilibria or states (Suding and others, 2004;
Walker and Meyers, 2004; Briske and others, 2008). The alternative
states that emerge from a threshold crossing vary and often exhibit
reduced ecological integrity and value in terms of management goals
relative to the original or reference system. Alternative stable
states with some limited residual properties of the original system
may develop along the progression after a crossing; an eventual
outcome may be the complete loss of pre-threshold properties of the
original ecosystem.
This book provides an up-to-date and comprehensive report on the
soils of Wisconsin, a state that offers a rich tapestry of soils.
It discusses the relevant soil forming factors and soil processes
in detail and subsequently reviews the main soil regions and
dominant soil orders, including paleosols and endemic and
endangered soils. The last chapters address soils in a changing
climate and provide an evaluation of their monetary value and crop
yield potential. Richly illustrated, the book offers both a
valuable teaching resource and essential guide for policymakers,
land users, and all those interested in the soils of Wisconsin.
In 2012, the FAA and USDA continued to make great progress with its
multifaceted approach for mitigating wildlife strikes. The FAA
ensured that 100 percent of Part 139 airports have completed a
Wildlife Hazard Assessment (WHA), are in the process of conducting
a WHA, or have taken a Federal grant to conduct a WHA. Strike
reporting continued to increase, especially with General Aviation
(GA) aircraft, which increased strike reporting by 11 percent
between 2011 and 2012. The FAA implemented three performance
metrics to monitor strike reporting trends and GA wildlife
mitigation. The performance metrics include percentage of damaging
strikes, strike reporting rates, and tracking of General Aviation
(GA) airports that conduct WHAs and site visits. We also issued a
final Advisory Circular (AC) on strike reporting and draft ACs on
WHA methodology and requirements for federally obligated public
airports to conduct WHAs.
The myriad definitions of soil/ecosystem quality or health are
often driven by ecosystem and management concerns, and they
typically focus on the ability of the soil to provide functions
relating to biological productivity and/or environmental quality
(Doran and Parkin, 1994; Karlen and others, 1997). A variety of
attempts have been made to create indices that quantify the
complexities of soil quality and provide a means of evaluating the
impact of various natural and anthropogenic disturbances.
A Kind of Magic is a three-volume novel of eco-magical realism.
It's a book about transition: from childhood to adolescence; from
isolation to community; from passivity to action. From fantasy to
the real world. It is deliberately aimed at 4th - 6th graders, and
can be read as a whole or as three short school library books. A
Trick of the Light/Turtle Crossing/ThunderHawk: A Trilogy of short
books for middle-grade readers; following a boy's awakening to the
beauties and needs of the natural world around him, with the help
of his friends, his family, his community and the mysterious spirit
of the forest.
This document describes a protocol to monitor five terrestrial
plant communities in seven national parks within the Pacific Island
Network (PACN).
