Invasive Juniper Trees Boosts Perennial Grass Recovery (Aug
Agricultural Resarch Service.
scientists have figured out that cutting down invasive
juniper trees and burning them in the wintertime
not only reduces the wildfire risk from the dead
trees, but also helps keep invasive cheatgrass at
bay and helps native perennial plants to become re-established.
Respond to the Spread of Invasive Mussels in the West (Aug
Fish and Wildlife Service.
The U.S. Fish
and Wildlife Service announced that nearly $600,000
will be awarded to nine projects targeting three
of the highest priorities from the Quagga-Zebra
Mussel Action Plan for Western U.S. Waters.
The plan provides a collective approach to fight
the westward spread of quagga and zebra mussels.
Bullfrogs Done in by Flash Floods (Aug 13, 2010)
Scientists surveying native tree frogs and invasive bullfrogs in the mountain
oases for Mexico's Baja California found evidence that the bullfrogs are blindsided
by infrequent, powerful tropical cyclones that can occur. The native frogs are
adapted to avoid the violent flooding that ensues after torrential rains, and
stay hidden and dormant during the summer and fall, when hurricanes are likely
to strike. Bullfrogs live and breed at the same time the hurricanes are active,
which makes them more vulnerable when hurricanes cross the Baja Peninsula. The
results of the study mesh with areas what many biologists have been arguing for
other places in western North America, which suffer from invasive fish. The fish
thrive in areas with dams with a normal amount of water, but remove the dam or
release water in a way that mimics the extreme high and low flows of many western
rivers, and the invasives suffer while the native species gain ground. The study
is published in the October issue of Journal of Arid Environments.
Secretary Vilsack Announces Selection of Collaborative Forest Restoration
Projects (Aug 13, 2010)
Agriculture Secretary Tom Vilsack announced the selection of Collaborative Forest
Landscape Restoration projects in nine states that promote healthier, safer and
more productive public lands. The projects include partnership efforts on forest
restoration treatments that reduce wildfire risk, enhance fish and wildlife habitats,
control invasive species, increase resistance to insects and diseases, and maintain
and improve water quality. Additional information on the program can be found
on the Collaborative Forest Restoration
Program (CFRP) site.
Highlights Report Showing Threats to Private Forested Lands (Aug
Agriculture Secretary Tom Vilsack held a national conference call to highlight
a USDA Forest
Service report entitled Private
Forests, Public Benefits: Increased Housing Density and Other Pressures on Private
Forest Contributions showing that privately held forests in the U.S. are
under substantial stress from development and fragmentation and that increased
housing density in forests will exacerbate other threats to forests from wildfire,
insects, pathogens and pollution. Information on threats from insects and pests
is in Part
3: Additional Pressures (PDF | 5.4 MB). The report is one in a series from
the Forest on the Edge project.
Facing Regional Extinction in the Northeast from Rapidly Spreading
Disease, UCSC Researcher Finds (Aug 5, 2010)
University of California - Santa Cruz.
A new infectious disease, white nose syndrome spreading
rapidly across the northeastern United States has killed millions of bats and
is predicted to cause regional extinction of a once-common bat species, according
to the findings of a Santa Cruz researcher. The disease, which was first discovered
near Albany, New York in 2006, affects hibernating bats. If the death rates and
spread continue as they have over the past four years, this disease will likely
lead to the regional extinction of the little brown myotis, previously one of
the most common species in North America. The findings are published in An
Emerging Disease Causes Regional Population Collapse of a Common North American
Bat Species in Science.
Service Updates Free Guide to Invasive Plants in Southern Forests (Aug
FS. Southern Research Station.
Gardeners, foresters, landowners and others concerned about nonnative invasive
plants in the South can request free copies of "A
Field Guide for the Identification of Invasive Plants in Southern Forests (PDF
| 11.4 MB)". The long-awaited book is an update of the very popular "Nonnative
Invasive Plants of Southern Forests: A Field Guide for Identification and Control",
published by the Forest Service in 2003, and gives users a more comprehensive
identification guide to nonnative trees, shrubs, vines, grasses, ferns and forbs
invading the region’s forests and other natural areas.
Dedicates August to Invasive Plant Pest and Disease Awareness (Aug
Animal and Plant Health Inspection Service.
this year, APHIS will engage the public
each August to increase understanding about the
risks that invasive plant pests, diseases and harmful
weeds pose to America's agricultural and natural
resources. See USDA's
blog for more information.

Lives in the Sea? Census of Marine Life Publishes Historic Roll
Call of Species in 25 Key Ocean Areas (PDF | 894 KB) (Aug
Census of Marine Life.
Census of Marine
Life scientists released an inventory of species
distribution and diversity in key global ocean
areas. The scientists combined information collected
over centuries with data obtained during the decade-long
Census to create a roll call of species in 25 biologically
representative regions -- from the Antarctic through
temperate and tropical seas to the Arctic. According
to the Census studies, the main threats to marine
life to date have been overfishing, lost habitat,
invasive species and pollution, although the relative
importance of the threats varied among regions.
The findings are published in a collection of papers, Marine
Biodiversity and Biogeography - Regional Comparisons
of Global Issues in PLoS ONE.
