Abstract The early twenty-first century has witnessed a fundamental paradigm shift in the biological sciences, transitioning from the macroscopic observation of organisms to the molecular detection of their genetic traces. This report provides an exhaustive analysis of the current state of DNA barcoding and environmental DNA (eDNA) biomonitoring programs globally as of 2024-2025. Synthesizing data from over 120 distinct research outputs, policy documents, and technical report

1. Introduction and Definition Environmental DNA (eDNA) is defined as genetic material obtained directly from environmental samples (such as soil, water, or air) without any obvious signs of biological source material. This method bypasses the need to isolate a specific target organism. Instead, it relies on the cellular material shed by organisms into their surroundings. eDNA is categorized into two primary types: * Microbial eDNA: DNA from unicellular organisms (bacteria,
