ESRM 450 Wildlife Ecology and Conservation FOREST STRUCTURE AND DEVELOPMENT Stand Dynamics and Succession
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
Edges change over time Recent edge Closed edge Embedded edge
Light is attenuated at forest edges How does light affect wildlife habitat?
Edges alter laminar wind flow How does wind affect wildlife habitat?
Extent of edge effects varies by forest type and environmental factor What factors cause this variability?
Forest development and succession can be modeled in different ways Oliver & Larson model of stand development following disturbance
Relative positions of canopy strata are important components of stand structure How can these strata help us interpret wildlife habitat?

Multiple successional pathways in southern boreal forest
Silviculture can influence the outcome of successional pathways
What information would you need to describe successional pathways?
