Subject: Tree Tips--Learning About LWD--2/13/03
Printed in the Mendocino County Observer
Forest landowners who want to learn about large woody debris have a terrific chance to do so at an upcoming workshop in Ukiah. The purpose of the workshop is to give people who own forest land or are involved in land
management a better understanding of what large woody debris (LWD) is, why it's important, and how to manage it. Put together by UC Extension, CDF,the Gualala Watershed Council and others, there is a great line-up of
speakers and topics, including an all-day field trip to the woods.
Many folks involved with land management know that it's important to have LWD, particularly in fish-bearing streams. LWD can help form pools, alter the flow of water, sort sediment, etc. In some places, there is plenty of
LWD, but in areas where more is needed, a little knowledge can help in determining the best course of action.
Not all woody debris is created alike. Logs from species like alder or willow compose relatively quickly, while other species like redwood, and particularly redwood with a lot of heartwood, will decompose slowly. Also, the size, placement, and number of pieces of woody debris determine how it influences water flow in a stream. Large pieces are more likely to stay in one place and take longer to decompose, while smaller pieces are more likely to move in the stream current and may form large or small dams.
If you are interested in finding out all you ever wanted to know about LWD and then some, sign up for this workshop. It will be held May 2 at Mendocino Community College, with a field trip on the 3rd to visit sites in the Gualala watershed and at Jackson Demonstration State Forest. The cost is $40 for one day or $65 for both days. For more information, contact Sherry Cooper at shcooper@ucdavis.edu or 530-224-4902.
