Evaluating a herpetofaunal monitoring program in the Rolling Plains of Texas.

摘要: We evaluated the herpetofaunal monitoring program on a state-owned property in Rolling Plains ecoregion of Texas to determine whether current study design and survey effort are meeting following objectives: (1) inventory diversity property, (2) improve understanding habitat preferences, (3) track response land management activities. used iChao1 species richness estimator evaluate sample completeness dataset, which was collected intermittently from 2004 2016. Species by site year as well pooled across sites years. Observed all years 23 species, estimated 23.999 (23.090–34.052, 95% CI). for each less than cumulative total, with 20 observed 2004, 6 2013, 11 2014, 19 The individual sampling ranged 6.250 39.320 species. Our analysis suggests that inadequate prevents three objectives being addressed using existing dataset. Necessary improvements meet include increasing spatial temporal scale utilizing random protocol. Monitoring methods address variation detection probability, such occupancy mark-recapture, will also need play role. findings show programs require substantial investment materials personnel obtain datasets sufficient rigorous biodiversity monitoring.
