Hedgerow Mapping and Surveying

Map hedgerows, identify species composition, and assess their ecological value as wildlife corridors.

Hedgerows are vital wildlife corridors supporting thousands of species. By systematically recording hedgerow structure, plant species, condition, and gap sizes, you'll contribute to conservation planning. Mapping hedgerows in your area reveals connectivity patterns and identifies priorities for management and restoration. This work bridges citizen science with habitat conservation.

How to start

  1. 1
    Identify local hedgerows accessible on foot; use parish maps or Google Earth to plan survey routes.
  2. 2
    Walk hedgerow lengths, recording woody species present, native/non-native status, and flowering times.
  3. 3
    Assess structure: height, width, density, gaps, presence of mature trees; photograph condition.
  4. 4
    Record bird, mammal, and insect observations within or using the hedgerow.
  5. 5
    Use GPS to map hedgerow locations and create a spatial database of surveyed sections.
  6. 6
    Return seasonally to track phenology (flowering, fruiting, leafing) and monitor changes.

Where to learn more

Plot twists

Ways to spice this up when the basics get boring.

  • Create a detailed species inventory of all woody plants in a hedgerow; track their flowering and fruiting phenology.
  • Map hedgerow connectivity to identify key wildlife corridors linking woodland patches.
  • Quantify hedgerow value by documenting wildlife (birds, mammals, insects) using mapped sections.
  • Document hedgerow management history and correlate with current structure and species composition.
  • Monitor seasonal changes in structure, flowering, and wildlife usage across multiple years.
ADHD notes

Repeat walks of the same hedgerows build routine and predictability. GPS tracking provides structure. Seasonal changes keep the activity fresh and engaging.

Fun fact

Medieval hedgerows can be aged using the 'Hooper method': counting woody species in a 30-meter stretch estimates centuries of age (approximately 110 years per species).
