The different habitat types recognized in the SSHIAP system are shown in the following table:

SSHIAP Database Code	Habitat Type	Description
1	Small Tributary	Stream with summer low flow wetted width <6m, OR basin area <23mi2 (~1/2 of a USGS 7.5’ quad).
2	Large Tributary	Stream/river with summer low flow wetted width ³6m, OR basin area >23mi2.
3	Side Channel	Persistent secondary channel, typically with a vegetated island or other persistent landform separating it from the main channel.
4	Side Channel Slough	Channel branching off the main stem with >90% pools.
5	Distributary Slough	Channel with >90% pools that branch off a mainstem and flow as part of or into an estuary.
6	Lake/Pond	Habitat with standing water all year. Shown as unbroken blue on USGS topos; verify with aerial photos.
7	Wetland/Pond Complex	Wetland with associated, perennial surface water pond(s). Shown as blue with grass symbols or unbroken blue on USGS topos; verify with aerial photos.
8	Seasonally Flooded Wetland	Wetland that holds water for only a portion of the year. Often have perennial surface water channels and are identifiable with aerial photographs. Shown in white with grass symbols on USGS topos.
