Vilas County Invasive Species Program


Published on

With natural resource conservation being such a hot topic, it is important to be able to inform and educate the public about invasive species dispersion and impacts. To assist with such efforts, the Vilas County Mapping Department has teamed with the Invasive Species Coordinator to help create effective teaching and reference materials that can be updated in a timely manner using GPS and other techniques. Examples of procedures and products will be showcased, as well as other invasive species issues and initiatives which illustrate departmental cooperation and creative funding.

  • Phones - Future technique? - Allows public to get involved - Pictures - Waypoints - Tracks
  • Creating data without importing shapefilesWhen working with others, it’s important to find a usable coordinate format (decimal degrees)Excel can be used to convert non-standardized text to coordinates*click*Create a feature class from the XY table Using ArcCatalog, right-click on table and choose to create a feature class from an XY table Define the projection as that of GPS unit, then reproject*click*Play connect-the-dots using the point attributes May be better ways This way is pretty simple when working with smaller datasets
  • AcreageSquare Feet
  • Calculate infestation area, pinpoint individual plantsDetermine parties responsible for treatment*click*Devise a treatment/prevention plan
  • Road segmentsTotal Length
  • First time working with Trimble unit, data not formatted very well
  • Identify study areasSpatial recognition of study surface area
  • Detailed close-up of study areaCollected invasive dataPoint, Lines and Polygons
  • Created shapefiles with necessary fieldsSet up GPS collector forms using ArcPad Area and line datasets have two data fields available -(expound on values)-*click*Point datasets add an additional two fields -(expound on values)-Once a feature has been created, the input box pops up and asks for informationPre-defined entries speed up data collection and ensure data consistency
  • Last example project. On to planning.
  • SearchDetermine ownershipExport listingsBufferMeasureGet coordinatesSave Maps/Drawings
  • Parcels identified based on proximity to plant observations*click*Parcels can be joined with attributes from the nearest observation pointTargeted mailings can be carried out, complete with detailed, parcel-specific observations
  • Can do more than just terrestrial invasivesHelps with treatment planningPresent for funding proposalsData classified, acreage calculated Determine amount of herbecide used Pinpoint application sites
  • Presentation piece created for all the different speciesUsed to give a large-format overview of species distributionHot-spots and watch areas clearly identified
  • Maps created in printer-friendly, universal formatsSimple and easy-to-understandEasy to distribute electronically or in mailings*click*Scalable for media consumptionFurther-generalized map for newspaper print/inline web graphicIncrease visibility of department

    1. 1. Cooperative Efforts and Practices of theInvasive Species Coordinator and Mapping Department
    2. 2.  Partnerships  Departments  Resource Conservation and Development (RC&D)  Regional Groups Equipment  Pen/Paper  Handheld GPS  ArcPad  ArcGIS  Personal Mobile Devices?
    3. 3.  Find a usable coordinate format Create a feature class from the XY table Play connect-the-dots using point attributes
    4. 4.  Objective: To quantify the extent of garlic mustard growing in the heart of town and identify on whose lands it was growing. Field mapping equipment:  Handheld basic GPS receiver  Paper & pen to record starting and ending waypoint for each polygon Method:  Collected polygon points around each patch  Requested map showing patch sizes and parcel lines
    5. 5.  Objective: To determine total miles of SK along county roadway ROW and evaluate potential for bio-control implementation Field mapping equipment:  Handheld basic GPS receiver  Paper & pen to record stop and start waypoint numbers for each Method:  Collected via “windshield” survey  Requested map highlighting ROW infestations
    6. 6.  Objective:  Evaluate selected private forest lands for presence of invasive plants  To increase invasives awareness by landowners Project partners:  Local RC&D provided funding  Vilas County provided employment services for field technician  Conserve School provided housing for technician  WHIP (weed co-op) provided Trimble unit  Mapping Dept. programmed Trimble
    7. 7.  Objective: Survey all county roads ROW for presence of invasive plants in advance of developing ROW invasive species management plans for Highway Commissioners Project partners:  Local RC&D provided funding and employment services to hire two LTEs  WHIP providing use of two Trimble units and oversight of LTEs  Mapping Depts. programmed Trimble units
