Heavy visitor use in many areas of the world have necessitated development of ways to assess visitation impacts. Arches National Park recently completed a Visitor Experience and Resource Protection (VERP) plan. Integral to this plan was developing a method to identify biological indicators that would both measure visitor impacts and response to management actions. The process used in Arches for indicator selection is outlined here as a model applicable to many areas facing similar challenges. The steps were: (1) Vegetation types most used by visitors were identified. Impacted and unimpacted areas in these types were sampled, comparing vegetation and soil factors. (2) Variables found to differ significantly between...

This data set is comprised of five files related to the modification and scoring of Index of Waterbird Community Integrity (IWCI) scores for all waterbirds of the Chesapeake Bay. One Excel file (A) contains a list of 100+ Chesapeake waterbird species and their species attribute and IWCI scores. Another Excel file (B) contains case study data from recent surveys of breeding and migratory waterbirds in Chesapeake Bay and shoreline delineations across a disturbance gradient that were used to demonstrate the utility of the modified index. Finally, three supplemental files include an Access database (C), R code (D) and a protocol (E) for running the complex steps to calculate index scores.

This dataset is comprised of six files related to waterbird surveys and resulting Index of Waterbird Community Integrity (IWCI) scores in 21 subestuaries of the Chesapeake Bay from 2010-2014. Two .csv files (1 data file: Prosser et al 2017_IWCI Results MS_Bird Survey Raw Data.csv, 1 definitions file: Prosser et al 2017_IWCI Results MS_Bird Survey Raw Data_Definitions.csv) contain data related to raw waterbird survey data from two seasons (summer and fall). Two .csv files (1 data file: Prosser et al 2017_IWCI Results MS_Species List.csv, 1 definitions file: Prosser et al 2017_IWCI Results MS_Species List_Definitions.csv) contain data related to 60+ Chesapeake waterbird species observed in surveys and their species...
