The Chesapeake Bay Trust has released a first-of-its-kind app, Field Guide to the Chesapeake Bay, that can be used to access data about the full range of plants and animals-not just a sampling-in the Chesapeake Bay watershed.

The free app also provides geographically targeted information so a user can be in Central Maryland or the Virginia Mountains and pull up data about plants and animals indigenous to those particular areas of the watershed.

"This Bay field guide will be a fun, educational companion for families, kids and nature-lovers on trips anywhere in the region and will provide instant, accurate and visually compelling information about the natural treasures that the Bay watershed has to offer," said Allen Hance, executive director of the trust.

The guide provides bird calls, pinchable photos, range maps, identifiable characteristics of animals and more. It has advanced search functions and is designed to be visually appealing and user friendly.

Hance said that he hoped the app would help the trust "reach a new generation of supporters and volunteers to advance our efforts to protect and restore the Bay. And as more and more people gain a new appreciation for and ultimately become stewards of the Bay, the entire watershed has a better chance of becoming clean and healthy again."

Available initially to iPhone users, the new mobile app is available from a computer through a link to www.cbtrust.org or by visiting the Apple Appstore from an iPhone and searching for Chesapeake Wildlife. The guide is free and a quick download.
