CONSERVATION BRIEFS 
Vandalism - Everyone knows that forest fires do miliions of dollars of damage : 
each year; but the US Forest Service now reports that vandals did $100,000 worth 
of damage to recreational facilities last year. 
Sedimentation - Erosion on highways, cropland, strip mines and suburban develop- 
ments is washing silt into our rivers to the tune of $500 million each year ac- 
cording to the Department of Agriculture. 
New Anti-Litter Symbol - The Bureau of Land Management has introduced Johnny 
Horizon, who may become as well known as Smokey, to publicize the campaign to 
clean up our public lands. 
Audubon House Saved - Mill Grove, where Audubon lived as a young man, has been 
saved by the re-routing of a proposed highway. The 206-year old stone house, 
near Norristown, Pa., contains a museum and the 122-acre estate serves as a 
wildlife sanctuary.

Parasitic Wasps May Save Elms - A tiny wasp which parasitizes the larvae of the 
beetles which carry the Dutch Elm Disease has been introduced from France and 
is being studied in Ohio. It is not certain whether the ovipositor of the wasp 
is long enough to pierce the thicker bark of the American elm. 
Trumpeter Swans Make Comeback - The population of trumpeters is now about 4,000 
and they have been taken off the endangered species list. In 1935, the popula- 
tion was 73. 46 of these in Yellowstone, but their numbers have been increased 
by raising the birds in captivity and transplanting them to their former 
breeding range. 
Voters Block Oil Plant - Voters in Santa Barbara County, California rejected a 
rezoning ordinance which would have enabled the Humble Oil Co. to build an oil 
processing plant along the scenic ocean-front. 
Thermal Pollution - By the year 2000, the nuclear power plant will be producing 
enough excess heat to raise the temperature of the Mississippi River by 100 de- 
grees. Ways to utilize or safely dissipate the waste heat are now being studied.
