The movies show smooth versions of the catch heatmaps over time. The date cursor at
the top shows the date range for each frame. The date cursor turns red in the summer months and blue in the winter months, so you can get a quick feel for how catches change
over seasons.

Rats and Stoats: focus on 2013-2015
This movie shows catches at a fine scale, month-by-month, covering 2013 to 2015 where
a major rat surge occurred. Trends are harder to see at this fine scale, but the
timing of surges is more precisely pinpointed.

Movies 2003-2016
These movies show results over time from the beginning of the Ark data in 2003. Because
we have data only for catches, and not for non-catches, traps (small squares) appear on
the map only when a catch was made during the corresponding timeframe.
