Last week, a large contingent of the OSU Forestry & Natural Resources Extension team traveled to the Gulf Coast of Mississippi for a biennial conference of natural resources Extension professionals. Besides the chance to exchange ideas with our colleagues from across the country, these meetings afford the opportunity to learn about the ecology and natural resources issues that define the geography of the meeting location.

We learned that the forests of Mississippi are quite diverse. They are defined by their topography, proximity to the coast, and (as in Oregon) landowner objectives. While on the surface they seem about as far from Oregon’s forests as you can get, there are some similarities to the forest systems and issues we have back home. We thought we’d share a bit about the interesting forests that we saw and learned about on our visit. Continue reading

Last week I attended Forest Health: State of the State, a biannual conference put on by OSU College of Forestry. A packed agenda covered insects, diseases, fire, drought, invasive species, climate change, and other topics. I always look forward to this meeting as an opportunity to brush up on my knowledge of these issues. The speakers came from various backgrounds, representing the many forest ecosystems and ownership types we have across the state, and the audience was equally diverse. With that in mind, I’ve tried to distill the takeaways from the conference that seem most relevant to small woodland ownerships in northwest Oregon.

Taking a walk through my NE Portland neighborhood recently, I came across something new in our local park. Portland Parks and Recreation is renovating an underutilized section of Alberta Park as a “Nature Patch”.

Alberta Park was part of a Homestead Act land claim over 150 years ago, and became a park in 1917. (Check out a local historian’s writeup for the details.) So over 150 years of human use, the land is far from the forest that once grew there. The Nature Patch could be thought of as a re-engineering project. Continue reading

Old basins found at the Matteson Forest probably belonged to a dairy farmer in the mid-20th century.

Ah, November. The wet and the darkness set in and we feel like turning on the teapot and bundling up. For woodland owners, winter lends an opportunity to catch up on indoor projects: accounting, taxes, and maybe updating or writing a management plan.

Another indoor activity that I guarantee will be more interesting than any of the above is researching and putting together a history of your woodland. It may mean digging through old family files or recording the memories of an elder relative, if your property has been in the family for a while. For those with a newer relationship to their land, it may mean a lot of online research. Either way, it can be a revealing and rewarding process; and by documenting what you learn you will gain a richer connection to  your woodland and ensure this history is not lost to future generations.

This month we have been spending some time at the Matteson Demonstration Forest getting ready for a commercial thinning project. The actual logging will happen next summer, but we are taking care of road improvements, surveying property lines, laying out the harvest boundaries and marking the stand now, so that we are ready to go when the contractor is available.  OSU forestry students who are summer interns with the OSU Research Forests gained hands-on experience by doing a lot of this work.

Lately on this blog we’ve been discussing ways to grow a diverse forest.  Many small woodland owners are interested in maintaining diversity on their land, yet strive to do it in a way that also brings in income from timber or other means. For these reasons, I was intrigued by the work of Julian Geisel, who recently wrapped up his master’s degree in the College of Forestry at OSU. His research topic, “Management Strategies for Small, Income Generating and Structurally Diverse Forests” is particularly relevant to small woodland owners. Julian’s research focused on private woodlands in western Oregon, representative of the vast majority of the owners that we work with in Extension. I interviewed Julian about his work. Continue reading

Through a creative and carefully planned harvest, this mature forest has undergone a structural diversity makeover.

Continuing our series, we’ll now look at steps that woodland owners can take to enhance structural diversity in their forests.  Recall that “structural diversity” refers to the amount of three-dimensional variation in the forest. In other words, a structurally diverse forest has trees of different sizes arranged in uneven patterns across the site.

Why do we care about structural diversity? Structural diversity is important to creating an “older” or “natural” forest look that many people want on their property.

Structural diversity is also a very important part of wildlife habitat. Continue reading

Our previous installment of this series introduced the key elements of forest diversity. Species diversity (a.k.a. compositional or biological diversity) is one of those elements.  So how do you achieve it, especially if what you are starting out with is a plantation forest with only a few species? The transition to an older forest with many plant species will not happen quickly. However, at every stage in a forest’s life cycle, there are opportunities and choices one can make to move the needle to a more species-rich forest.

The rest of this article and the accompanying infographic takes us through these choices, stage by stage. Continue reading

Tree planting season is upon us. Once the deep freeze departs western Oregon woodland owners will be heading out, shovels and seedlings in hand, to plant the next generation of forests.  The saying “green side up” implies that tree planting isn’t rocket science; but inevitably, come late summer some people will return their planting sites to find that their trees didn’t fare so well.  Weather and other uncontrollable factors cause seedling mortality some years more than others.  But, it’s also easy to unintentionally harm your trees before they even get in the ground. So before you go to a seedling sale this year to pick up a few trees, here are some common cases of seedling abuse and how to avoid perpetrating them.

A balmy sunny day might entice you outdoors, but it's not ideal weather for tree planting.

Happy fall!
Happy fall!

For the fourth installment in our series on native shrubs that are beneficial to wildlife, I’ve chosen one that appropriate to the season, provides some nice fall color to our forests.  Now I’ve met more than a few woodland owners who are not fans of vine maple; it’s not a favorite of those who prefer a tidy or parklike forest. Working or wandering in mature forests you’ve probably tripped over it or crawled under it and possibly cursed it under your breath.  Nevertheless, vine maple is another of those “brush” species that benefits wildlife in numerous ways. With some tolerance for its rambling ways you can find a place for this species to provide that service on your woodland in concert with your other land management goals.  If you are interested in enhancing wildlife habitat on your property, read on for our species profile.

Species name: Vine maple (Acer circinatum)
