If one of your land management goals is to provide wildlife habitat, you’ll want to consider keeping a mix of native shrub species on your property. Shrubs provide a host of services to wildlife, including shelter or cover, nesting space, and food from their twigs, leaves, flowers, and fruit. With thought given to species selection and location, retaining existing shrubs or planting them can benefit wildlife without compromising timber growth or forest operations. This is the third article in our Shrubs for Wildlife series (see others here and here). Each article highlights one species that benefits wildlife in northwest Oregon forests.

Species Name: Oceanspray (Holodiscus discolor)

Management activities are underway at the Rubie P. Matteson Demonstration Forest near Hagg Lake. As any new property owner can attest, the first year of property management entails a mix of addressing immediate needs and thinking about longer-term goals and plans. This year, our activities are focused on mapping, inventory and rehabilitation as well as readying the property for public use. Below is a summary of recent and ongoing projects on the forest.

With thought given to species selection and location, retaining existing shrubs or planting them can benefit wildlife without compromising timber growth or forest operations. This is the first article in a series intended to help you recognize some of the “brush” species that may exist on your property, and understand how they may fit with your management goals. Each article will highlight one species that benefits wildlife in northwest Oregon forests.

“What’s with all the logging going on?” is a comment I’ve heard more than once recently. Rural residents of northwest Oregon seem to be noticing an uptick in timber harvest from their industrial neighbors over the past year or so. I wondered whether these observations were simply anecdotal, or if they signaled a rebound from the recession, or if they were evidence of a more historic rise in harvest rates. So I decided to dig into some local data on recent forest ownership and harvest trends. Continue reading →

Recent posts on this blog have examined the problem of forest seedling supplies for small woodland owners, and the compromises that sometimes come with limited seedling choices. While the situation has gotten worse in the last couple of years, it is not a new dilemma. Cooperative seedling buying programs, where a group of landowners collectively contract with a nursery for their seedling needs, are one way that small woodland owners have worked to ensure a reliable seedling supply for themselves and their neighbors.

Both the Columbia and Washington County chapters of the Oregon Small Woodlands Association (CCSWA and WCSWA, respectively) have organized annual seedling programs for their members for the last 15+ years. The two programs have much in common, with a few differences. They each sell about 50,000-70,000 seedlings/year, distributed among dozens of members. Paul Nys (CCSWA) and Bob Shumaker (WCSWA) have been organizing forces behind these programs since their outset. I talked with Paul and Bob to shed some light on the benefits and challenges of keeping these programs going for the benefit of groups in other areas that may want to consider this approach.

The summer of 2015 is shaping up as a big year for drought and drought related forest health issues throughout Oregon, but especially in the Willamette Valley, SW Oregon, and in Eastern Oregon.

In late summer, it can be very difficult to discern whether insects, disease, or drought and heat are causing tree dieback and deaths, but we are becoming pretty confident that drought and heat together are influencing much of what we see. In this report I outline and describe some of the more common problems we are seeing with conifers and hardwoods as of early September.

Like just about any small woodland, the Matteson Demonstration Forest has its share of invasive weeds. Besides familiar and ubiquitous foes such as Scotch broom and thistles, one of particular concern is knapweed.

With purple flowers emerging from roundish bases at the top of a tall stalk, knapweeds superficially resemble a sort of spineless thistle, and in fact they are relatives of thistles, botanically speaking. They are biennial (2-year life cycle) to perennial plants and reproduce by seed. Fairly inconspicuous in the winter and spring; at this time of year, their purple flowers betray their location on and along roadbeds and other disturbed areas. Continue reading →

I don’t need to tell you it’s hot out there today. (Oops! I just did. Sorry.)

Between the extreme heat and the very real fire danger, it’s not a good afternoon to be working in the woods. Rarely do I say I’d rather be in the office than in the field, but today is one of those days that I’m appreciating the air conditioning.

Since everyone is talking about the weather anyhow, it seems appropriate to share some reading material that relates to it, which you can enjoy in the comfort of whatever cool spot you’ve found today. Oregon Forests and Climate Change is the subject of a little writing project which a number of my Extension colleagues have taken on as a group. Continue reading →

This must be the end of the road... — This must be the end of the road…

One of the first orders of business on the Matteson Demonstration Forest is getting to know the lay of the land. 180 acres is a lot to get to know! As is the case with any new woodland owner, we need a map to help orient ourselves while on the property, and to keep track of where different roads and trails lead.

Eventually, the OSU College Forests staff will create a GIS map of the Matteson Forest with various spatial layers – property boundaries, roads, forest types, culverts, and so forth. In the meantime, I’ve been using Google Earth to create my own map, adding information as I continue to explore the tract. While in the woods, I’ve been using a GPS app on my smartphone to keep track of where I am and to record points and paths. In this article I’ll describe how I’ve been using these two applications, which I think would be useful to most woodland owners who don’t have GIS at their fingertips. Continue reading →
