Why are there more lakes and streams data in PEARL than wetlands, estuarine, coastal and terrestrial data?
This is simply a time issue. PEARL started about 8 years ago as an on-line forum for serving lakes data. Modifications to PEARL’s internal architecture that now enable other data types to be served on PEARL have been made only in the past 1-2 years. Now that these capabilities are in place, PEARL users will see an increasing number of both lake and non-lake data displayed on the site.
