    • Range of Fencing Studies With and Without Complementary Infrastructure/Activities

      • One-Way Gates

      • Wildlife Crossings

      • Active Maintenance and Animal Removal

      • Cattleguards

    • 60 to 97 Percent Reduction Range in Animal Mortality (Result Patterns?)

    • Primarily 8-Foot (2.44-Meter) Fencing Used - Studies of Other Heights are Questionable


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


Ongoing summary cont

ONGOING SUMMARY (Cont.)


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

EXAMPLE 1/4-MILE DVC PATTERN


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
