planting_site_id int8 19 null
planting_sites.id observations_planting_site_id_fkey C
created_time timestamptz 35,6 null
start_date date 13 null

First day of the observation. This is either the first day of the month following the end of the planting season, or 6 months after that day.
end_date date 13 null

Last day of the observation. This is typically the last day of the same month as start_date.
completed_time timestamptz 35,6 √ null

Server-generated date and time the final piece of data for the observation was received.
state_id int4 10 null
observation_states.id observations_state_id_fkey R
upcoming_notification_sent_time timestamptz 35,6 √ null

When the notification that the observation is starting in 1 month was sent. Null if the notification has not been sent yet.
planting_site_history_id int8 19 √ null
planting_site_histories.id observations_planting_site_history_id_fkey C

Which version of the planting site map was used for the observation. Null for upcoming observations since monitoring plots are only placed on the map when an observation starts.
observation_type_id int4 10 null
observation_types.id observations_observation_type_id_fkey R
is_ad_hoc bool 1 null
