Queries the bcfishpass.streams_vw table for stream segments with modelled
habitat (rearing or spawning) for a given species and watershed group.
Usage
fly_query_habitat(
conn,
wsgroup,
habitat_type = "rearing",
species_code = "co",
blue_line_keys = NULL,
stream_names = NULL,
min_stream_order = NULL
)Arguments
- conn
A DBI connection to a bcfishpass database.
- wsgroup
Watershed group code (e.g.
"BULK","LNIC").- habitat_type
"rearing"or"spawning".- species_code
Species code:
"co","ch","sk","bt","st","wct","cm","pk".- blue_line_keys
Numeric vector of FWA blue_line_key values (preferred — unique per stream).
- stream_names
Character vector of GNIS stream names (convenience — scoped to wsgroup).
- min_stream_order
Minimum Strahler order (applied in addition to blk/name filters).
