  • Slide 2
  • Scale measures or quantifies differences among observations Extent (or range) describes the realized scope of a phenomenon or entity of interest Grain (or resolution) describes how finely observations within the extent are divided or distinguished
  • Slide 3
  • Edges change over time Recent edge Closed edge Embedded edge
  • Slide 4
  • Light is attenuated at forest edges How does light affect wildlife habitat?
  • Slide 5
  • Edges alter laminar wind flow How does wind affect wildlife habitat?
  • Slide 6
  • Extent of edge effects varies by forest type and environmental factor What factors cause this variability?
  • Slide 7
  • Forest development and succession can be modeled in different ways Oliver & Larson model of stand development following disturbance
  • Slide 8
  • Relative positions of canopy strata are important components of stand structure How can these strata help us interpret wildlife habitat?
