A major impediment to wider use is that most data reside on paper labels. This information is tedious and slow to obtain. Many institutions are turning to retroactive data capture to give new life to collections.
Databases now exist that allow a window into the characteristics of the collection.
Most specimens originated in the 1920-30s. Secondary peaks occurred in the 1960-70s, with activity in the 1990s. This enables INHS researchers to judge EPT species losses through time.
