Columns
| Name | Type | Description |
|---|---|---|
| shift | text | Value is either "AM" or "PM," to communicate whether the sighting session occurred in the morning or late afternoon. |
| number_of_squirrels | number | The number of squirrels sighted in the hectare during the sighting session. |
| total_time_of_sighting | number | The sighting session duration, in minutes. |
| date | text | Concatenation of the sighting session month, day, and year (MMDDYYYY). |
| hectare_conditions | text | Value is one of the following: “Calm”, “Moderate”, “Calm, busy” or “Busy.” The difference between “moderate” and “calm, busy” is as follows: “moderate” was either entered by the sighter, or translated from an entry that described a condition somewhere in-between busy and calm. “Calm, busy” was either entered by the sighter or translated from an entry that described discrete hectare sections as busy, but other hectare areas as separately calm. |
| number_of_sighters | number | The number of sighters that observed the hectare for the sighting session. Values range from "1" to "3." |
| hectare | text | ID tag, which is derived from the hectare grid used to divide and count the park area. One axis that runs predominantly north-to-south is numerical (1-42), and the axis that runs predominantly east-to-west |
| anonymized_sighter | number | Sighter names were alphabetized then assigned a number (1-267) so that the individual abilities and characteristics of each sighter could be taken into account. |
| sighter_observed_weather | text | Each sighter was asked to describe the weather conditions before starting each sighting session. Weather values varied widely, and are in some cases inaccurate. |
| other_animal_sightings | text | Comma separated values indicating other animals sighted in the hectare. A list of other animals common to the park were provided; however, other animals were listed as well. |
| hectare_conditions_notes | text | Sighters occasionally added commentary on the hectare conditions. These notes are provided here. |
| litter_notes | text | Sighters occasionally added commentary on the amount or quality of litter. These notes are provided here. |
| litter | text | Value can be "None", "Some" or "Abundant." |
