new 2003 summaries cont
NEW 2003 SUMMARIES (Cont.)
  • Exclusionary Fencing
    • Potential Factors that Impact Fencing Effectiveness:
      • Proper Installation (e.g., Height, Location/Length, and Strength)
      • Active Maintenance/Repair
      • Complementary Infrastructure
      • Vigilant Removal of Animals
      • Location with Respect to Woods, Grazing Land, and Topography
      • Suggested Extension of Ends 1/2-mile (0.8 km) beyond Activity Area
new 2003 summaries cont1
NEW 2003 SUMMARIES (Cont.)
  • Roadside Vegetation Management
    • Suspected DVC Impacts are Mostly Anecdotal
    • Further Analysis/Study Needed
    • Summary Includes List/MN Tool Site
  • Public Awareness/Education and Hunting or Herd Reduction
    • Part of a Complete DVC-Reduction Program, but Impacts of Policy Changes are Difficult to Prove
    • No Studies on Educational DVC Impact
    • Models Show Relationships between Herd Density and DVC Trends (One of Several Variables)
    • Small Area Hunting Studies Show Some Potential
new 2003 summaries cont2
NEW 2003 SUMMARIES (Cont.)
  • Roadway Development Decisions
    • Proposed: Inherent Consideration of Animal Mortality in Maintenance, Design, and Planning/Programming Decisions and Processes
    • Potential DVC-Reduction Impacts
    • Some GIS and Expert Systems Combining Habitat and Safety Information to Identify Existing/Proposed “Wildlife Critical” Locations
ongoing summary
ONGOING SUMMARY
  • Wildlife Crossings
    • Effectiveness Often Measured by Animal Use rather than DVC-Reduction
    • Some Potential Factors that Impact Use: Location, Adjacent Topography/Vegetation, Geometrics, Fencing, and Human Activity
    • Variability in Studies (e.g., Species, Crossing Designs, and Location) Limits Transferability of Specific Conclusions
    • Great Study Summary in “Road Ecology” Book
regional data survey
REGIONAL DATA SURVEY
  • Final Form on Web and then Hard Copy in Next Few Months
  • 9 DNR Questions and 18 DOT Questions
  • Written Responses and Telephone Follow-Up
  • Primary Focus: Deer, Vehicle Travel, and DVC Data Characteristics, Collection, and Management
survey cont
SURVEY(Cont.)
  • Objectives
    • Share DVC-Related Data Characteristics and Collection/Management Procedures Used by Individual States with DVCIC Partners and Beyond
    • Allow Proper DVC-Related Data Comparisons Between and Within States
    • Allow Proper DVC-Related Data Combinations within Region Annually and from Year to Year within States
    • Similar National Consideration at TRB
some data survey conclusions
SOME DATA SURVEY CONCLUSIONS
  • Annual Deer Population Estimates done Pre- or Post-Hunt at DMU or County Level
  • DNRs Rarely Consulted on Roadway Planning Projects about Animal/Vehicle Conflicts
  • Other States: Carcass Removal Primarily a State and Local DOT Job - Done When Needed but Usually not Recorded
  • DNRs Typically Not Consulted about Deer Crossing Sign Locations
conclusions cont
CONCLUSIONS (Cont.)
  • States in Region are Using Reflectors, Fencing/Bridges, Crossing Signs, and Crossing Signs with Detectors as Countermeasures (Some Studied for Effectiveness)
  • Minimum Crash Reporting Thresholds Vary ($400 to $1,000) and Almost all Have Changed during Last 10 Years
  • Two DOTs Appear to have a Rule of Thumb Consideration to Install Crossing Signs
uw sign study
UW SIGN STUDY
  • Presented at 2004 TRB/Paper on Website
  • Plotted Deer Carcass Removal (DCR) to DVC Ratios by County [State Average Ratio: 2.2]
  • Ranked Counties by Six DCR and DVC measures:
    • Total Magnitude
    • Per HMVMT
    • Roadway Mile
    • Land Area
    • Human Population
    • Deer Population
sign study content
SIGN STUDY CONTENT
  • Selected Five Counties/38 Sign Pairs
  • Considered 1/4-Mile and Segment DVC Rates and Frequencies
  • Evaluated DVC Peaking Patterns
  • Suggested Seven Step Installation Guidelines
    • State Average
    • County Average
    • DVC Peaking Between Signs

proposed installation guidelines
PROPOSED INSTALLATION GUIDELINES
  • Step 1: Site Visit/Segment Definition
    • Determine Physical Limits
    • Discuss with Natural Resource Staff
    • < 1.0 Mile (Reconsider Sign Installation)
    • > 5.0 Miles (Consider Multiple sign Pairs)
  • Step 2: DVC Data Collection
    • Define Sign Segment Plus 2 Miles in Each Direction
    • Three Years of Location-Based DVC Data
    • County and State Averages
installation guidelines cont
INSTALLATION GUIDELINES (Cont.)
  • Step 3: DVC Measure Calculations
    • DVCs/mile/year and DVCs per HMVMT
    • 1/4-Mile and Average Segment Measures Between and Outside Signs
  • Step 4: State/County Average Comparison
    • Between Sign Average Measures > State Average
    • Between Sign Average Measures > County Average
    • If Either is Not True: Reconsider Installation
installation guidelines cont1
INSTALLATION GUIDELINES (Cont.)
  • Step 5: Between to Outside Comparison
    • Calculate Between to Outside DVC Measure Ratio and Compare to 1.0 and County Average (If Available)
    • If Less than Either: Reconsider Installation
  • Step 6: Positive Sign Location (PSL) Determination
    • Is Site a PSL (i.e., Are 1/4-mile DVC Measures and Averages Between Signs of Study Site)?
    • If not: Redefine Proposed Sign Location and Study Site (See Step 7).
installation guidelines cont2
INSTALLATION GUIDELINES (Cont.)
  • Step 7: Redefine Sign Study Site
    • Consider Peak DVC Measures for each 1/4-Mile, Between Signs, and Outside the Signs
    • Shift Study Site to Include All Measures Between Signs (i.e., a PSL Results)
    • Lengthen Study Site to Include All Measures Between Signs
    • If Redefined Length > 5 Miles Consider Multiple Sign Pairs
    • Reapply Procedure from Step 2 for Redefined Study Site
guideline limitations
GUIDELINE LIMITATIONS
  • Installation Only Allowed at Sites with DVC Problems > Existing Sites
  • Effectiveness Depends on Previous Decisions
  • Required Measures Can be Difficult to Collect, Calculate, and/or Update
  • Adjustments Needed if Applied to Existing Sign Locations
