Park Design with Wildlife in Mind

– Assistance: Bat boxes, hollowed/fallen trees, revegitated culverts, habitat vegetation cover (non-maintenanced) – Pollution Concerns: Noise, Water, Light – Prevention: dog park zones, poop bags, trash cans covered, recycle bins – Signage: regulatory (ordinances), interpretation, Do not feed, Speeding – Camera Monitoring: Who’s where

Areas for Wildlife, Areas for Humans?

What are you examining? Is it gooey, moist, smelly, stiff, old, does it have invertebrates on it?

Step 1: Examine the Parts

slide-23
SLIDE 23

Step 2: Why only Guts?

Why are there a only guts? Where are the other parts

  • f the body?

Why isn’t there blood? What animals might be eating what is currently viewed?

slide-24
SLIDE 24

Step 3: Analyze Surroundings

Are there any drag marks to or from the site? What hidden areas are close by,

  • ffering predator protection?

Are there any pieces of the prey that can give insight to what specie it was? Gut piles are fabulous indicators

  • f carnivorous behavior.

Enjoy from a distance –

nature’s nuggets may contain harmful bacteria.

  • Eye Sockets
  • Teeth
  • Brain Case
  • Special Features (Horns or Antlers)
