Description: The HCLAM_LNVOL2 depicts known hardshell/softshell clam habitat areas within Kachemak Bay. This data was digitized from mylar original maps from the Kachemak Bay and Fox River Flats Critical Habitat Areas Management Plans (1993) and updated bluelines from area biologists (1997 and 1999). Data for the following categories were captured: Known concentrations - areas where concentrations of hardshell/softshell clam have been observed. Data in this coverage exists only for the Kachemak Bay area; data are not continuous along the coast. This coverage contains only line data for hardshell/softshell clams. For polygon data in this area see HCLAMVOL2.
