Drones Spy Invasives
Monika Chandler, an invasive species specialist with the Minnesota Department of Agriculture, needed a more efficient means of finding
invasive plants such as oriental bittersweet.
She teamed up with the University of Minnesota's Aerospace Engineering and Mechanics
Department to explore the use of drones, or
unmanned aerial vehicles (UAVs). Page 10.
Forests Increasing or Decreasing?
You may have read news articles earlier this
year about a study recently published in the
journal PLOS One, "Forest dynamics in the US
indicate disproportionate attrition in western
forests, rural areas and public lands." For example, United Press published "Study: The
forest is getting farther away, especially in rural America," on February 22. However, the
US Forest Service's Forest Inventory and Analysis unit reports that the nation's forest area
has been relatively stable since about 1900.
Greg Reams, national FIA program manager,
and Mark Nelson, an FIA research forester,
shed more light on the subject. Page 16.
The People Performance Hierarchy
In this month's SAF Leader Lab column, Tom
Davidson writes, "As a forest manager, your
job is likely to involve diagnosing problems
in the woods and coming up with solutions
based on your observations, training, and experience, as well as landowner objectives. As
a people manager, you will also have to diagnose people problems and come up with solutions to those as well." Davidson offers an example of such a people problem and describes
a tool to help you diagnose what to do on the
"people side" of your business. Page 18.
The Timber Innovation Act
Donald Radcliffe, SAF's Henry Clepper Forest
Policy Intern, takes a look at the Timber Innovation Act (TIA), which would establish an
R&D program for innovative wood products
such as cross-laminated timbers (CLTs). Page

nvasive insects, plants, and other
non-native pests pose a bigger challenge
to forest managers than ever before.
One insect, the emerald ash borer (EAB), is
considered the most destructive forest pest
ever seen in North America, according to
the Emerald Ash Borer Information Network (emeraldashborer.info). Since it was
found in Detroit, Michigan, in 2002, EAB
has spread to 25 states and two Canadian
provinces, killing hundreds of millions of
the estimated 8.7 ash trees in the US. However, insecticides can save urban ash trees
from EAB, and foresters have several options for maintaining ash in forests, such as
by unleashing insectoid parasites of EAB.
See the article on page 4. Another article
on page 6 describes the Oregon Forest Pest
Detectors (OFPD) program, which trains
foresters, arborists, park managers, and
others to identify and report invasive species, including EAB, the Asian long-horned
borer, and other species.
Since 1980, the European gypsy moth
has defoliated trees on about one million
or more acres each year. In 1981, 12.9 million acres were defoliated-an area larger
than Rhode Island, Massachusetts, and
Connecticut combined. See page 8 for a
look at West Virginia's efforts to control the

ash borer in China, is being released in the US as a biological control of EAB. Photo: David Cappaert,
Drones, or unmanned aerial systems,
seem to be everywhere these days, including looking for invasive plants from
above-Oriental bittersweet in Minnesota, for example. See page 10. On page 12,
read about the Mississippi Forestry Commission's new app for helping in the fight
against cogongrass, a scourge of forests in
the US South and Southeast. And although
the article about the White Sands Missile
Range, which begins on this page, doesn't
focus on invasives, it does describe the
range managers' efforts to eradicate saltcedar, or tamarisk, from riparian zones.
Managing Natural Resources and Missile Tests at the White
Sands Missile Range
By Andrea Watts
n six months, SAF members will converge in Albuquerque, New Mexico, for
the 2017 SAF National Convention. As
part of The Forestry Source's coverage leading up to the convention, we will highlight
forestry and natural-resources management activities throughout the state. Our
first article features the White Sands Missile Range (WSMR), where cutting-edge
military testing isn't the only research taking place. I had the opportunity to visit the
area in mid-March. Whereas most tourists
visit the White Sands National Monument
or the WSMR Museum, I wanted to learn
about the management of the installation's
natural resources. Fortunately, Adriana
Salas, with the WSMR Public Affairs Office, was able to help satisfy my curiosity.
Encompassing 2.2 million acres,
WSMR is the largest military installation in
the United States. Since its establishment
in the 1940s, the US Army has managed
WSMR for research, development, testing, and evaluation of military systems
and similar high-technology commercial
products. In addition to the Army, the Air
Force and Navy also conduct testing and
research at the installation.
The White Sands Missile Range is home to numerous birds, including year-round resident golden eagles.
The installation's avian protection plan was written by Rick Harness, and resource-management projects are
designed to avoid negative impacts on the birds. Photo: Rick Harness.
Although "white sands" conjures visions of a desert-like environment, a variety of ecosystems are found throughout
the installation-from basaltic-rock terrain to shrubland and woodlands. The
San Andres Mountains run along the
western border before jutting eastward,
and the Oscura Mountains are located in
