Ancient Biodiversity
The same arguments about 1) the need for adaptability and 2) that we
should look to past to consider how best to deal with the future are also
gaining currency within the fields of environmental management and, in
particular, with regards to issues of biodiversity.
As with landscape
management, policy documents relating to environmental conservation and
biodiversity “rarely look back more than 50 years and may ignore the historical
context entirely. This has been a lost opportunity for understanding ecological
systems. Many natural processes occur over timescales that confound our
attempts to understand them, so the vast temporal perspective provided by
palaeoecological studies can provide important guidance for nature conservation
(Willis & Birks 2006)” (Hodder et al. 2009, 4).
Similar to W.G Hoskins, certain key scholars have pushed the agenda
forward and notable amongst these is Oliver Rackham whose
work on the history of Britain’s flora and fauna has highlighted how
biodiversity has changed through time, reflecting millennia of
human-environment interactions and showing that humans are, and have always
been, a force of nature – we are certainly not separate from it.
The rise of global trade
has seen a sharp increase in the number of plants and animals transported
around the world by humans, purposefully or inadvertently. Many of these
introductions are legacies of ancient societies, dating back thousands of
years. They have radically altered the environment, sometimes detrimentally by
outcompeting native species in the absence of natural predators.
