This dataset contains individual counts of 10 African mammal species in the Garamba National Park (Democratic Republic of the Congo) from 1976 to 2017.
Format
A data.frame with 141 rows (counts) and the following 8 variables:
- location
the location of the survey (Garamba)
- species
the binomial name of the species
- date
the date of the survey
- stat_method
the method used to estimate individuals counts. One of
T(total counts),G(guesstimate), andS(sampling counts)- field_method
the field method used to collect data. One of
A(aerial counts), andG(ground counts)- count
number of individuals
- lower_ci
lower boundary of the 95% confidence interval of the counts (only for sampling counts)
- upper_ci
upper boundary of the 95% confidence interval of the counts (only for sampling counts)
- pref_field_method
the preferred field method of the species. One of
Afor Aerial counts, andGfor Ground counts- conversion_A2G
the conversion multiplicative factor (corresponding to the detectability category) used to convert aerial to ground counts
- rmax
the maximum population growth rate
