SILENT MENACE THREATENS WORLD WHALE STOCKS (NOAA)
St. George's, Grenada -- U.S. Commissioner D. James Baker
urged the group to better determine how global environmental
changes may jeopardize whale stocks throughout the world. "The
threats to whales from global environmental change are extremely
widespread, and appear to be increasing," said Baker. "Issues such
as increasing levels of chemical contaminants, rising sea surface
temperatures and decreasing sea-ice coverage are problems that
extend from pole to pole, across most marine ecosystems, and, as
a result, affect all whale populations. We must determine more
precisely and urgently the potential risks of global environmental
changes on whales."

SEASTARS INVADE AUSTRALIA WATERS
A marine invader has established itself in Australia, and is
rapidly expanding its numbers and its range, Australian scientists
report. The Pacific seastar, Asterias amurensis, poses a serious
environmental threat to coastal centers from New South Wales to
Western Australia, the scientists conclude.

USGS Report Assesses Nation's Biological Resources
The U.S. Geological Survey has released the first large-scale
assessment of the nation's natural resource heritage in a
two-volume report, "Status and Trends of the Nation's Biological
Resources." At century's end, this report synthesizes current
information within a historical perspective to document how the
nation's biological resources are changing. The report also
underscores the essential need for science to be used in guiding
decisions on resource management.

SENATE RIDER CALLED THREAT TO WETLANDS
A rider attached to a bill recently passed by the Senate could
potentially endanger wetlands by granting a lenient appeals process
to developers while creating more red tape for the U.S. Army Corps
of Engineers. The rider, attached to the Senate energy and water
development appropriations bill, would allow developers to appeal
an U.S. Army Corps of Engineers decision that wetlands exist on
certain private property. On the other hand, the rider would not
allow other interested parties to appeal, no matter what the corps
decided.
