• Ecosystem modeling – NASA (SIEN – YOSE)
• NASA internship program (SIEN, Fire, USFS)
• NASA Proposals and grants:• Invasive species & fire (Welch, Paintner, Benson, Morrisette)• Monitoring proposal (Hansen et al.)• Land use and climate effects on biodiversity in 70 large parks
(Hansen & Running)• Park Science paper – I&M and NASA (Turner, Nemani, Gross)• National Phenological Network • Heinz Center – terrestrial and coastal groups
NDMI, 1989 to 2004
Draft protocols: • NCCN • GRYN • NCRN
Bandelier National Monument March 4, 1999
Networks and Landscape Dynamics
NCCN Protocol – Warren Cohen and Robert Kennedy • Very large and remote parks
• Landsat focus: cheap, consistent, historical, good near short-wave
• Track changes in broad physiognomic classes• Many changes described as proportional mixture changes

NCCN Protocol – Warren Cohen and Robert Kennedy • Very large and remote parks
• Landsat is core of effort• Cheap, consistent, historical, good near short-wave sensor
• Track changes in broad physiognomic classes• Many changes described as proportional mixture changes
• Multi-tiered validation approach
• Focus on pixel-based products• Solid foundation for post-map analysis• Facilitate patch or super-pixel pattern analyses
GRYN Protocol – Hansen / Jones
• Large area
• Land use intensification in critical habitats
• Excellent conceptual models linking landscape change to resources
• Extensive use of remotely sensed and ancillary data
Mechanism Type of effect Monitoring
Change in effective size of reserve
Species area effect
Minimum dynamic area
Tropic structure
Land use and habitat area
Disturbance patterns
Wildlife populationsChanges in ecological flows into and out of reserve
Disturbance initiation and runout zones
Placement in watershed or airshed
Disturbance patterns
Water & air quality
Impoundments / hydrology
Loss of crucial habitat outside of reserve
Ephemeral habitats
Dispersal or migration habitats
Population source / sink habitats
Land use and habitat location
Animal movements
Animal demography
Increased exposure to human activity at reserve edge
Poaching
Displacement

Linking landscape change to park resources
Public data
Spatial Dataset Source
Housing and population density U.S. Census Bureau (2000)
Water discharge permit records State Department of Environmental Quality; U.S. EPA
Land cover USGS, NLCD; NOAA CCAP, LandFire
Conventional water pollution EPA National Watershed Characterization
Hydrologic modification EPA National Watershed Characterization; NPS impoundments database
Cities National Atlas of the United States
Overall population change U.S. Census Bureau
Change in farmland acreage U.S. Census of Agriculture; State Agriculture Statistics Services
Trends in major dam construction U.S. Army Corp of Engineers and FEMA, National Inventory of Dams
Changes in housing density U.S. Census Bureau, “Profile of Selected Housing Characteristics”
(modified from Hansen and Gryskiewicz 2003)
Plus: roads, lights, imagery archives
• Many small parks in rapidly urbanizing landscape
• Effects of imagery resolution
• Pattern analysis based on graph theory
• Comprehensive testing and review of protocol
(Figure: Townsend et al. draft protocol)
NCRN Protocol – Townsend, Gardner, & Lookingbill
Lessons leaned
Many opportunities for broad-scale analyses
• Core vital signs,
• Major potential to use inexpensive, widely-available data,
• Change detection - use of inexpensive high-frequency, coarse-resolution data to strategically acquire expensive data,
• Scale of objectives consistent with USGS, EPA, NOAA, PCA,
• Potential for program-wide efficiencies in data processing and analysis,
• Potential collaborations at local to international scales.
Finer-scale landscape dynamics (often vegetation change)
• Partnership opportunities at regional, network or biome scale
• Many more network- or park-specific issues
• Change detection is a very big issue (resolution, cost)
Parks Canada Approach
Large collaborative project with limited set of objectives:
• Habitat fragmentation / pattern
• Vegetation succession / retrogression
• Vegetation productivity
• Biodiversity (species richness)
Efficiencies from a highly focused group with clearly objectives. Very rapid progress and consistency.
Agencies: PCA, CCRS, CSA, Universities
Lesson:
How can we best monitor linear park units?
NETN, GLKN, HTLN
Appalachian Trail & river-based parks
What’s on the horizon?
What’s in the future
Emergence of a National Phenological Network
• Seasonal changes are one of the most pervasive environmental variations on Earth
• Effects seen in agriculture, transportation, health, hydrology, etc.• Direct link between monitoring results and broader social values
• http://www.uwm.edu/Dept/Geography/npn/
Why we want a National Phenological Network
• Priority vital sign for multiple networks,
• Standardized protocols,
• Ability to use and contribute to broader context,
• Leverage activities by others,
• Excellent means to link and add value to other measures.
Implementation team meeting – March 22-23, 2006
Involves USGS, USFS, EPA, NOAA, NASA, NPS, universities
What’s in the future
Greater use of ecosystem modeling for monitoring and management
• Rama Nemani, NASA Ames – Terrestrial Observation and Prediction System (TOPS).
• Current link to NASA internship program• Pilot project with SIEN – Yosemite NP• Hope to expand to Island Royale• Educational process

What’s in the future
Coordinated acquisition of regional to national data?
• Focus on broad-scale data sets:• Land cover, roads, population, agricultural records, pollution, etc.• Linkages to MRLC, Landfire
• Consistent evaluation, system-wide context
MRLC land cover zones
