NREL IN THE LIMELIGHT
USGS and NREL Establish the National Institute of Invasive Species
Science
Tom Stohlgren, and other scientists from NREL and the
Fort Collins Science Center, established the first national-scale
institute to document, map, and predict the distributions and
effects of non-native plants, animals, and diseases in the US.
They have developed long-term partnerships with NASA to greatly
increase the speed of predictive spatial models for forecasting
invasive species distributions using high performance computing.
In partnership with the USFWS National Wildlife Refuge System,
they are now completing the first phase of a 5-year program.
NREL researchers are working with the Colorado Agricultural Experiment
Station to improve mapping of invasive plant species in Colorado.
NREL researchers have recently established the NBII (National
Biological Information Infrastructure) Invasive Species Information
Node http://invasivespecies.nbii.gov/.
Niall
Hanan, NREL Research Scientist, organized a workshop
on African savanna ecology, funded by his NSF project “Biocomplexity
in African Savannas.” The workshop took place in South Africa
in January with about 30 participants, including leading African
savanna ecologists from Africa, the US, and Europe, as well as
graduate students and managers. Products from the workshop include
on-going analyses of continental-scale patterns that contrast
savanna ecology and dynamics in the different regions of Africa,
and a special section on African savannas planned for the Journal
of Biogeography.

In a paper
entitled “The Rich Get Richer: Patterns of Plant
Invasions in the United States,” USGS/NREL scientist Tom
Stohlgren and coauthors David Barnett (NREL Research Associate)
and John Kartesz (Biota of North America Program, Univ. of North
Carolina) summarize two large, independent datasets to show exactly
the opposite pattern. At multiple spatial scales, but more significantly,
at larger spatial scales, hotspots of native plant diversity
have been far more heavily invaded than areas of low plant diversity
in most parts of the US. The findings suggest that hotspots of
native plant species richness are unlikely to repel invasions,
and that the threats of species invasion are significant and
predictably greatest in species-rich areas. The work was published
in the inaugural issue of “Frontiers in Ecology and the
Environment,” a new journal of the Ecological Society of
America.
