Data and code from: Evaluating baselines for long-term ecological monitoring of biodiversity trends: Insights from the US National Ecological Observatory Network carabid data

Evidence is mounting that rapid environmental change threatens global insect biodiversity, underscoring the need for informed conservation strategies that protect both species and the ecosystem services they provide. Armed with accurate baseline community data, long-term continental-scale monitoring projects are invaluable for detecting and predicting responses to ecological change. However, high species diversity and temporal variability in population sizes can hinder our ability to establish baselines, and, thus, obscure, exaggerate, or reverse temporal trends in long-term insect data. With its scale and consistent protocol, the US National Ecological Observatory Network (NEON) carabid pitfall trapping data provides an excellent case study for evaluating sampling effort. We use species incidence-frequencies calculated from more than 200,000 identified carabids across up to 10 years of sampling and 46 field sites to extrapolate asymptotic richness and diversity metrics. We find that th..., , # Data and code from: Evaluating baselines for long-term ecological monitoring of biodiversity trends: Insights from the US National Ecological Observatory Network carabid data

## Description of the data and file structure

This code is designed for the purpose of analyzing open ecological data provided by the National Ecological Observatory Network. Specifically, this project investigates organismal observational data in order to calculate sampling necessary for understanding richness and diversity at NEON sites distributed across the country.
