Mark-recapture and estimated abundance data of marsh rice rats (Oryzomys palustris) trapped on oiled and unoiled plots in Plaquemines Parish, Louisiana from 2013-04-07 to 2017-06-10

Marsh rice rats were captured during April-June in 2013-2017 at four oiled and three unoiled sites in southeastern Louisiana. Animals were trapped using Sherman live traps and tagged with ear tags and/or PIT tags (PIT tags were added during the 2017 field season and were only applied to adult animals weighing over 30g). The mark-recapture dataset contains capture information (location, tag numbers) and encounter history over three consecutive trap nights. The abundance dataset contains derived estimates and statistical information calculated in the software program MARK, which provides parameter estimates (e.g. abundance) based on mark-recapture data.
