This study brings together decades of research on the modern
natural environment of Washington's Olympic Peninsula, reviews past
research on paleoenvironmental change since the Late Pleistocene,
and finally presents paleoecological records of changing forest
composition and fire over the last 14,000 years. The focus of this
study is on the authors' studies of five pollen records from the
Olympic Peninsula. Maps and other data graphics are used
extensively. Paleoecology can effectively address some of these
challenges we face in understanding the biotic response to climate
change and other agents of change in ecosystems. First, species
responses to climate change are mediated by changing disturbance
regimes. Second, biotic hotspots today suggest a long-term
maintenance of diversity in an area, and researchers approach the
maintenance of diversity from a wide range and angles (CITE).
Mountain regions may maintain biodiversity through significant
climate change in 'refugia': locations where components of
diversity retreat to and expand from during periods of unfavorable
climate (Keppel et al., 2012). Paleoecological studies can describe
the context for which biodiversity persisted through time climate
refugia. Third, the paleoecological approach is especially suited
for long-lived organisms. For example, a tree species that may
typically reach reproductive sizes only after 50 years and remain
fertile for 300 years, will experience only 30 to 200 generations
since colonizing a location after Holocene warming about 11,000
years ago. Thus, by summarizing community change through multiple
generations and natural disturbance events, paleoecological studies
can examine the resilience of ecosystems to disturbances in the
past, showing how many ecosystems recover quickly while others may
not (Willis et al., 2010).
