Inventory and Monitoring Forest Invasive Species with Airborne Remote
Sensing:Honeysuckle in the Taconics

The Question
• Can invasive plants be detected over a large scale in forested systems using remote sensing technology?
![Page 3: Inventory and Monitoring Forest Invasive Species with Airborne Remote Sensing: Honeysuckle in the Taconics Katie Joseph and Robert Turner, RJ Turner Company.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649f225503460f94c3af3b/html5/thumbnails/3.jpg)
The Opportunity
• Vermont TNC was investigating 3,700 acres in core of Equinox Highlands matrix block
• Matrix block: large scale, relatively unfragmented landscape, bounded by fragmenting features such as roads
![Page 4: Inventory and Monitoring Forest Invasive Species with Airborne Remote Sensing: Honeysuckle in the Taconics Katie Joseph and Robert Turner, RJ Turner Company.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649f225503460f94c3af3b/html5/thumbnails/4.jpg)
The Opportunity• Timber cruise plus
information on presence of invasives
• Opportunity to apply new technology to the problem – AIMS-1 technology: high
resolution multispectral airborne imagery with stereo capability
![Page 5: Inventory and Monitoring Forest Invasive Species with Airborne Remote Sensing: Honeysuckle in the Taconics Katie Joseph and Robert Turner, RJ Turner Company.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649f225503460f94c3af3b/html5/thumbnails/5.jpg)
• Equinox Highlands• 63,000 A landscape• Northern Taconics• Mountainous (3,800 ft)
• 90% forested• Marbles; carbonates
The Site
Mt. Equinox

The Threat• Bush honeysuckles• Japanese barberry• Buckthorn
![Page 7: Inventory and Monitoring Forest Invasive Species with Airborne Remote Sensing: Honeysuckle in the Taconics Katie Joseph and Robert Turner, RJ Turner Company.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649f225503460f94c3af3b/html5/thumbnails/7.jpg)
The Threat• Timber cruise
data gives us an indication of where invasion is occurring and what species pose the greatest threat
Insert Map of cruise points with colors indicating the presence of honeysuckle and barberry

Our Goal: Differentiate invasives from surrounding, native vegetation• The 3 invasives leaf out early, stay
late• Heights are definable, shrub strata• High probability of invasion near
disturbed and open areas
![Page 9: Inventory and Monitoring Forest Invasive Species with Airborne Remote Sensing: Honeysuckle in the Taconics Katie Joseph and Robert Turner, RJ Turner Company.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649f225503460f94c3af3b/html5/thumbnails/9.jpg)
The Tools• Low elevation photography
– 75 cm pixel size: full coverage– 15 cm pixel size: sample coverage– Multispectral (red, blue, green, and
near infrared)– Stereo capability for both 15 cm and
75 cm (3D viewing)

The Process: Data• April 26, 2006:
– Flight with the AIMS-1 sensor (Mt Holyoke Geoprocessing Lab)
– Initial Ground Control Collection with GPS
• Fall 2006:– Additional Ground
Control Collection with GPS
Insert Map of photo centers: 15 cm and 75 cm (Flight Paths)

The Process: Image Preparation• Image pre-processing
– Create stereo blocks for stereo interpretation: 3D viewing
– Create orthophotos (correct for variation in terrain) and orthomosaic (stitch all of the orthophotos together to make a single image)

• Stereo interpretation (3D viewing) used to differentiate vegetation types and strata – Serves as training
in classification
The Process: Analysis
![Page 14: Inventory and Monitoring Forest Invasive Species with Airborne Remote Sensing: Honeysuckle in the Taconics Katie Joseph and Robert Turner, RJ Turner Company.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649f225503460f94c3af3b/html5/thumbnails/14.jpg)
The Process: Analysis• Supervised Classification
• Accuracy Assessment: How did we do?
![Page 15: Inventory and Monitoring Forest Invasive Species with Airborne Remote Sensing: Honeysuckle in the Taconics Katie Joseph and Robert Turner, RJ Turner Company.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649f225503460f94c3af3b/html5/thumbnails/15.jpg)
Results so far
• More ground-truthing needed this fall• Preliminary results—honeysuckle detectable• Spatial accuracy better than timber cruise, we can get
precise location for single shrubs• Remaining question whether honeysuckle signature
“clean enough”
![Page 16: Inventory and Monitoring Forest Invasive Species with Airborne Remote Sensing: Honeysuckle in the Taconics Katie Joseph and Robert Turner, RJ Turner Company.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649f225503460f94c3af3b/html5/thumbnails/16.jpg)
Feasibility
• Cost• Remote sensing expertise & software
needed• Imagery can be custom flown, easily
arranged

Additional Remote Sensing Opportunities with AIMS-1 products• Forest stand typing• Forest inventory• Coarse woody debris inventory• Future flights: Invasive plant monitoring
over time
