Bartram's Stonecrop (Graptopetalum bartramii) survey data from southern Arizona, 2020-2021

These data were compiled for the U.S. Fish and Wildlife Service to assist them with updating the current status of the species Bartram's Stonecrop (Graptopetalum bartramii). Objective(s) of our study were to survey selected sites within the of Bartram's Stonecrop for future management and protection. These data represent summary population counts at selected known sites for the Federally listed Threatened plant species, Bartram's Stonecrop (Graptopetalum bartramii). These data were collected in the southern Arizona portion of the species' range, stratified across Sky Island Mountain ranges from the Rincon Mountains south to the Atascosa Highlands, just north of the Mexican border. Sites were selected to represent...

Alamagan, Commonwealth of the Northern Mariana Islands, Nightingale Reed-warbler point transect survey data, 2010

Point transect distance sampling data were collected during the 2010 surveys of Alamagan, Commonwealth of the Northern Mariana Islands (CNMI). Data were collected at points along transects where trained observers recorded the detection type (heard, seen, or heard then seen) and horizontal distance (exact distance in m) from the station center point to individual birds detected during an 8-min count. To increase the numbers of detections, survey data from 40 detections from the CNMI Division of Fish and Wildlife (DFW; 2000) surveys of Alamagan, and 46 detections from Saipan surveys described in Camp et al. (2009) were added to this dataset. The count length of the DFW surveys was only 5 minutes; therefore, we included...
