THE PROBLEM
DoD alone has military bases with over 25 million
acres of land, more than 11 million of which are
training lands under Integrated Training Area
Management (ITAM).
Todays training/testing needs lead to changes in
the ecosystem that may exceed the current
estimated annual cost of 56M in land repair and
maintenance.
Hence, DoD has a need for efficient tools,
models, and techniques to better characterize
and quantify the carrying capacity of DoD land
resources to support military training and
testing.

PROBLEM STATEMENTS
understand how human activities compare to
natural disturbance through time and space.
Adaptive Management requires that the results of
management actions be measured and used to guide
future actions.
Such perspective should assist federal agencies
with efforts to maintain sustainable conditions
for land uses.

TECHNICAL OBJECTIVES
Stratify the landscape of individual military
ranges using contemporary and emerging remote
sensing technologies. Identify the fundamental
vegetation and soil attributes of military ranges
as they relate to plant succession, carrying
capacity, habitat management, and land
resources. Identify the spatial, spectral and
temporal attributes of remote sensing systems
necessary to identify ecotones. Establish
ecosystem response and recovery in relation to
disturbance (land use) through retrospective
studies with spatially-explicit spectral-based
indices. Develop methods for scaling through
multi-resolution imagery.

TECHNICAL APPROACH

• Retrospective Analysis
• Investigators
• ORNL, USU, TEC
• Goals Temporal/Spectral
• Establish ecological history in relation to land
  use to describe how activities affect ecosystem
  and landscape response and recovery, i.e.,
  resilience.
• Identify the range of variation in the
  characteristics of disturbances associated with a
  landscape.
• Determine the existence of thresholds in response
  and recovery to natural and DoD activities.

• Ecotone and Disturbance Gradient Analysis
• Investigators
• UNR, UIUC, CERL, TEC
• Goals Spatial/Spectral
• Assess high resolution systems to identify the
  sensor attributes necessary to monitor changes in
  plant species composition along disturbance
  gradients and plant successional stages.
• Calibration of scales to allow extrapolation over
  larger geographic regions.

TECHNICAL APPROACH (continued)

• Retrospective Analysis
• Dry/Wet season anniversary Landsat images, from
  1972 to the present, will provide historical
  context.
• RFMSS and other land management data will
  characterize the land disturbance.
• Spectral Indices of land degradation will relate
  traditional field measurements to their
  respective imagery counterparts.
• Spectral Indices will then be related to a sites
  ecological resilience and critical thresholds,
  thus representing the point where significant
  change in plant species composition occurred.
• Topographic/hydrologic models will relate
  topographic features (e.g., sinks, sources) to
  soil and vegetation indices.

TECHNICAL APPROACH (continued)

• Ecotone and Disturbance Gradient Analysis
• Localized detailed maps will be derived from high
  resolution remote sensing systems based upon
  botanical composition and related land cover
  characteristics, and defined by carrying capacity
  models.
• Contemporary and emerging image data will be
  utilized where,
• Contemporary satellite imagery will identify and
  map landscape level communities associations, and
• Emerging imagery with progressively higher
  spatial and spectral will stratify the landscape
  into progressively more detailed, hierarchical
  levels.
• Fundamental attributes of disturbance will be
  studied as they relate to plant succession.
• Multi-scale/Multi-spectral/Multi-temporal remote
  sensing systems will be used to relate remotely
  sensed data to ecological parameters, i.e.,
  correlate imagery to measures of seral stages.
