# Invertebrates of the Andrews Experimental Forest: An annotated list of insects and other arthropods, 1971 to 2002

## Dataset

- **Database Code:** SA001

- **Title:** Invertebrates of the Andrews Experimental Forest: An annotated list of insects and other arthropods, 1971 to 2002

- **Abstract:**

This publication is not a pro forma species list; rather, it has been generated as the result of diverse ecological studies centered on and around the Andrews Forest beginning in 1971. No attempt has been made to exhaustively collect the area with methodologies appropriate to each invertebrate group. This list provides some insight into the enormous invertebrate diversity present in the coniferous forests of the Pacific Northwest. It provides reference material for investigators who might be engaged in ecological investigations. We hope that these data, set in an ecological context, will stimulate collaboration and facilitate the design of future research.
