Although we have been very careful with all the spreadsheets and numbers below, we may have missed something. If you find a mistake, please email us at clear@uconn.edu and send it to the attention of the buffers project. Thanks.
The results of this research are primarily presented as the statistical tables and maps of individual subregional watersheds, the basic unit of the study. This detailed information is too involved to list on this web page, so we’ve created some very lengthy tables in PDF format are available via the links below.
In all cases, the data is compiled for each sub-regional basin by BASIN NUMBER. You must know the basin number you are looking for. You can find your basin number by:
Sub-regional Basin Name
A Map (zoomable pdf)
In Adobe reader, you can turn layers in the pdf on and off using the layers tab on the left side.
For reference, we also have a list of
Sub-regional Basin Names Sorted by Sub-regional Basin Number
* Basins are numbered in a nesting fashion. The first of the four digits represents the Major Basin Number. The second digit represents the Regional Basin and the last two digits represent the Sub-regional Basin.
Land Cover and Land Cover Change by Sub-Regional Basin
Land Cover and Land Cover Change by Sub-regional Basin
