| The plan for cyberinfrastructure (CI) support for future LTER research has just been released as part of the “‘Decadal Science Plan for LTER”. The CI strategic plan was commissioned as part of the overall LTER Network planning process with the express purpose of identifying CI critical to meeting LTER’s research and education objectives. As part of this process, the CI planners convened a large and diverse group of information technology (IT) professionals from science and technology centers, large IT development projects, and national observatory initiatives. |

| Giant kelp forests are amongst the most productive ecosystems on Earth. They provide food and shelter for a highly diverse community of fish, invertebrates and under story algae. Kelp forests are also highly dynamic ecosystems. Maximum growth rates for giant kelp (Macrocystis pyrifera) fronds can exceed a foot a day while entire kelp forests can be wiped out by a single winter storm. |

| Golden foliage greeted a dozen writers and a handful of scientists at the Bonanza Creek (BNZ) LTER site outside of Fairbanks on a recent Sunday in September. The focus of their interest was the 2004 Bondary Fire, one of the largest fires of that record fire season, which scorched 6.7 million acres. Together we looked at the ecological consequences and remembered the year that it occurred. Was the ecosystem devastated or was this part of natural rhythms of boreal forests? How did that summer’s smoke color the perceptions of Fairbanks residents about boreal wildfires, which had robbed them of that scarce resource called summer? |

The 11 LTER projects reviewed in 2007 comprise the largest cohort for a site review year. These sites reach almost to both poles and range from the open ocean to mountaintops, representing a scientifically and geographically diverse and logistically challenging combination. Consequently, NSF staff from across the Foundation facilitated particular reviews or came along as observers, in addition to the two LTER Program Directors in the Division of Environmental Biology (DEB) in the Directorate for Biological Sciences (BIO), Henry Gholz and Martyn Caldwell.

| The LTER network will reach an important milestone with regard to data documentation this summer: All LTER sites will be contributing metadata standardized in Ecological Metadata Language (EML) to the LTER Network Data Catalog. Standardization of data documentation is a critical step in the development of information systems to support ecological synthesis. Currently the LTER Data catalog hosts over 5,500 documents searchable at http://metacat.lternet.edu.The latest contributors to the catalog are the newer LTER sites–Moorea Coral Reef (MCR) and the California Current Ecosystem (CCE). |

FCE study on carbon sequestration by mangrove forests in the southwest Florida Everglades
In October 2005, hurricane Wilma severely disrupted the Florida Everglades ecosystem. Fringing mangrove forests exposed to hurricane-level winds were effectively destroyed, while more sheltered forests were severely damaged. At the FCE-LTER flux tower site (SRS-6), about a third of the trees were destroyed and roughly 3 cm of carbonate mud added on the mangrove forest floor. All instruments on the flux tower were also destroyed (Figure 1) and the tower itself damaged beyond repair and had to be replaced. The boardwalks and supporting structures also had to be re-built. |

| Most ecologists will agree on the necessity and importance of synthesis to address new ecological questions, yet synthesizing desired data products from a diverse array of complex datasets in a robust and reproducible way is a challenging task. Now, teams of researchers from the Harvard Forest Long-Term Ecological Research site (HFR) and the LTER Network Office (LNO) have advanced the knowledge of designing and building scientifically rigorous on-line information systems that will directly and significantly enhance ecological synthesis. |

| The LTER Network Office (LNO) is coordinating access by LTER sites to historical and recent satellite reconnaissance data, as well as MODIS time series subsets and imagery from the International Space Station. This effort is to provide access for LTER sites to data that are acquired and archived by collaborating partners, including the National Aeronautics and Space Administration (NASA) and the United States Geological Survey (USGS). Information on these and other LTER Network remote sensing data is available on the LTER remote sensing and GIS information page at www.lternet.edu/technology/ltergis/. |
