docs - note species presence per watershed data (data/wsg_species_presence.csv) as first step in access model

[smnorris]

Pacific Salmon, Steelhead and Westslope Cutthroat presence per watershed group were verified/QA'ed by CWF for the WCRP process (with the exception of Pink and Chum outside of the railway study area). For other species, this table simply records whether there is an observation within the watershed group, there has been no QA of observations.

• verify/QA PK/CM watersheds outside of railway study area
• verify/QA BT/CT/DV/GR/RB watersheds as required, with short term emphasis on BT

Note also that this table must be highlighted and clearly documented in docs

The data is generally being fixed on a case by case basis as users target or review more areas, but highlighting this data in the docs is high priority
