Forest Service Chief Max Peterson 
made the decision, in July of this year, 
to relocate MAG in Ft. Collins, Colorado. 
The relocation will permit greater day- 
to-day contact with groups such as the 
Resources Evaluation Techniques Project 
located at the Rocky Mountain Forest and 
Range Experiment Station, the USDA Ft. 
Collins Computer Center and Colorado 
State University. Additionally, Ft. 
Collins, with its geographic location, 
provides for easier access to the field 
and more efficient travel connections. 

Office space has been obtained at 
Drake Executive Plaza, a new office 
complex on the south side of the city, 
approximately one mile from the Rocky 
Mountain Forest and Range Experiment 
Station headquarters. Our new address 
i s: 

Suite 350, Drake Executive Plaza 

2625 Redwing Rd. 

Ft. Col Tins, CO 80526 

Our new phone numbers are: 

FTS 323-5265 

Comm'l 303-223-5025 

Present plans are to activate the new 
office in October 1981. The existing 
Davis location will remain in operation 
until the end of December 1981, to phase 
out current projects. This Newsletter 
will be the last published from the Davis 

The pesticide application activities 
will remain at the Davis location. 

First van load to Ft. Collins 


In cooperation with the Pacific 
Southwest Forest and Range Experiment 
Station an evaluation of alternative 
sampling strategies for MPB loss surveys 
in lodgepole and Ponderosa pines has been 
completed. Data obtained from surveys 
conducted between 1976 and 1980 were used 
for this evaluation. Results are being 
summarized to provide a guide for future 
surveys. Factors considered in this 
evaluation were number of photo plots, 
number of photo plots for ground truth, 
number of subplots for ground truth, 
sampling error, and cost in terms of 
manpower required. Information obtained 
from this study can be used to determine 
sample size required and to achieve a 
specified sampling error when estimating 
losses from Mountain Pine Beetle. 


A westwide inventory of mortality 
caused by the mountain pine beetle in 
lodgepole and ponderosa pine forests is 
underway. Purpose of this survey is to 
estimate current levels of tree mortality 
and volume loss by land ownership. The 
survey is the first attempt to provide 
statistical data with levels of precision 
in accordance with standards set by Level 
II of the Forest Insect and Disease 
Information System (FIDIS). 

Forest Service Regions involved in 
the survey are the Northern Region (R-l), 
Missoula, Montana; Rocky Mountain Region 
(R-2), Denver, Colorado; Intermountain 
Region (R-4), Ogden, Utah; and the 
Pacific Northwest Region (R-6), Portland 

The Survey is a multistage probabil¬ 
ity proportional to size (PPS) design and 
involves aerial sketch mapping, large 
scale color aerial photography and ground 
sampling. Aerial photos were obtained 
with a Forest Service aircraft based at 
the Pacific Southwest Region (R-5) and by 
contract aircraft. 

When completed, the survey will pro¬ 
vide data on the location of infested 
areas by major 1andownership classes and 
estimates of numbers of trees killed and 
cubic foot volume loss for Oregon, 
Washington, Idaho, Montana, Wyoming and 
Utah. Final data should be available in 
January 1982. 


As part of the westwide mountain pine 
beetle loss survey, an aircraft naviga¬ 
tion system was evaluated for locating 
aerial photo plots. The system evaluated 
was the Global Navigation System GNS-2, a 
VLF/Omega Navigational System. 

The system was installed in the 
Forest Service's Aero Commander based in 
the Pacific Southwest Region (R-5). This 

aircraft was used to acquire aerial 
photos for a mountain pine beetle loss 
survey of Oregon and Washington and a 
special survey to risk-rate ponderosa 
pine stands on the Black Hills National 
Forest in South Dakota for hazard of 
mountain pine beetle infestation. 

According to Jule Caylor, Remote 
Sensing Specialist for the Forest Service 
Pacific Southwest Region in San Fran¬ 
cisco, who flew the photo missions, 
search time in navigating between photo 
plots is reduced but the system is not 
yet accurate enough to pinpoint plot 
locations. In the mountain pine beetle 
surveys of Oregon and Washington, flight 
time was estimated to be reduced from a 
projected 120 hours to 80 hours at a cost 
saving of $7,000. 


In cooperation with the Morgantown 
FPM Field Office, of the Northeastern 
Area, MAG is investigating the use of 
high altitude panoramic aerial photog¬ 
raphy to detect and classify gypsy moth 
defoliation in central Pennsylvania and 
northeastern New Jersey. Photography was 
taken during peak defoliation from a U-2 
aircraft with the IRIS II optical bar 
camera, an improved version of the KA80A 
camera. The color infrared frames cover¬ 
ing a scan angle of 140° have been 
indexed on county road maps and their 
scales computed and averaged (1:32,500). 
Equal-area grids generated by the 
Geometronics staff of the Rocky Mountain 
Region in Denver, Colorado, will be used 
to classify defoliation. Photo intrepre- 
tation to delineate infestation bound¬ 
aries and stratify defoliation categories 
wi11 begin this fall. 



The pandora moth, on occasion, is a 
serious defoliator of pines in the West. 
It becomes epidemic about once every 20 
to 25 years. Therefore, a forest ento¬ 
mologist working in the west may encoun¬ 
ter this pest once during his profes¬ 
sional career. 

During 1979 the pandora moth reached 
epidemic proportions on the North Kaibab 
Plateau in Arizona near the north rim of 
the Grand Canyon. FPM (R-3) conducted a 
pilot test against this insect using 
Orthene, in Spring 1981.

Northern Region estimate spray deposit

trials on the Deerlodge NF in Montana 

A variety of specialized assistance 
was provided by MAG on this project. 
Since the insect becomes epidemic at such 
infrequent intervals, virtually nothing 
is known about sampling the population. 
Bob Young, in col 1aboration with John 
Schmid of the Rocky Mountain Forest and 
Range Experiment Station, conducted some 
preliminary investigation on the distri¬ 
bution of larvae in infested stands to 
help develop a pre- and post-spray 
sampling strategy. In additon. Bill 
Ciesla (MAG) teamed up with Jule Caylor 
of the Pacific Southwest Region in San 
Francisco to obtain color infrared aerial 
photos of the spray blocks and surround¬ 
ing stands before and after spraying to 
help determine the degree of foliage 
protection achieved by the spray. Pre¬ 
liminary results indicate that aerial 
photos can be used for detecting overall 
control effects. 

Assistance in aircraft calibration 
and spray deposit assessment was provided 
by Jack Barry and Patti Kenney.

Pilot control projects designed to 
evaluate two commercial preparations of 
the bacterial insecticide Racill us 
thuringiensi s were conducted during June 
1981 fn the Northern Region (R-l) and 
Southwestern Region (R-3). The purpose 
of these projects was to evaluate Di pel 
4L and Thuricide 16B for protecting 
relatively small acreages of high value 
Douglas-fir and true fir. 

The projects were conducted in 
accordance with a common statistical 
design developed by a task force of 
Regional FPM and Research personnel. 
Jack Barry of MAG served as project 

Both projects were conducted as 
planned with a minimum of difficulty. 
Materials were applied with turbine 
powered agricultural aircraft which 
performed well in rugged mountainous 
terrain. Larval mortality is presently 
being analyzed and plans have been 
formalized to monitor egg mass numbers, 
defoliation, and 1982 larval density in 
treated and untreated areas through the 
next field season. 

MAG specialists provided assistance 
in aircraft calibration and character¬ 
ization and spray deposit assessment. 
The two projects provided an opportunity 
to evaluate spray deposits on Douglas-fir 
needles, the primary target for the 
aerial spray. This work is presently 
underway. In addition, Bob Ekblad of the 
Missoula Equipment Development Center 
(MEDC) conducted tests of several new 
drift and spray deposit samplers. 


Brian Sturgess (R-5) and Jack Barry 
(MAG) monitored spray drift during an 
aerial spray project (Malathion) to 
control grasshoppers in a pine plantation 
on the Stanislaus NF, California. USDA- 
APHIS conducted the aerial operations 
while FPM personnel positioned spray 
deposit cards in the spray area and along 
a buffer strip surrounding a spring. MAG 
analyzed the data and summarized 
presented results. The low volume 
application with a Bell 204 was 
successful in reducing the grasshopper 
population with only minimal drift.

Three contracts dealing with pesti¬ 
cide application technology are being 
administered by FPM/MAG. The field phase 
of a mountain spray drift study was 
completed in June. The contractor, ESC, 
is analyzing the data and a report will 
be issued in 1982. A second contract is 
with Ketron, Inc., and calls for develop¬ 
ment of a systematic approach to aerial 
application. The plan resulting from 
this contract will provide the framework 
for FPM direction in aerial application 
technology. A report will be released 
early in 1982. A third contract, with 
H.E. Cramer Co., of Salt Lake City, Utah, 
will provide technical assistance to FPM 
in the use of the Forest Service CBG 
Forest Spray Model. This contract 
continues through 1982. Jack Barry is 
the COR for these projects. John Wong is 
assisting with the Cramer contract. 


Bill Ciesla presented a paper 
describing the application of panoramic 
aerial photography in Forest Pest Manage¬ 
ment at the Eighth Biennial Workshop on 
Color Aerial Photography in the Plant 
Sciences in Luray, Virginia. 

John Wong gave a special lecture to 
the University of California, Berkeley, 
Entomology Department, in the application 
of the Douglas-fir tussock moth Stand- 
Outbreak Model as a pest management 
decisionmaking tool. 


With the transfer of MAG to Ft. 
Collins, the staffing of MAG will take on 
a substantial new look. 

Bill Ciesla, Group Leader, and 
Eleanor Franz, Adminstrative Tech, will 
relocate in Ft. Collins and form the 
nucleus of the new unit. Bill will
