The health of insect pollinators is an issue of increasing concern and attention.  Both managed bees (honeybees) and native bees face various threats, including diseases, chemical use, and loss of suitable habitat. While pollinators can include other insects (flies, butterflies, etc.), bees are considered some of the most important. Without healthy bee populations, many flowering crops we humans depend on would not flourish; and native ecosystems that other animals depend on would be impaired.

Because many individuals and organizations are interested in protecting and conserving bees in Oregon, the Oregon Bee Project came into being in order to be a clearinghouse of information, a facilitator of bee conservation and education initiatives. Last week the Oregon Bee Project hosted the PNW Pollinator Summit in Corvallis, a two-day conference designed to bring together researchers, Extension, non-profits, and other groups that are involved in pollinator conservation. I got to attend and was especially interested in the presentations and field trip focused on forests and forestry. Continue reading

In a previous post , I wrote about the value of roads for a woodland owner, as well as the responsibly to maintain roads to protect their value as well as our water resources.  Many family forest landowners have older, “legacy” roads.  These older roads were likely not built to today’s engineering standards, have lost some of their function over time, so are deserving of some attention and stewardship.

So what does that involve?

It likely begins with observation.  Make it a habit to get out and inspect your road system regularly.  Since water is a key element and force causing damage to roads, get out in the wet season.  Bring paper, make notes and keep them as a reminder of what you saw and did.

When on your walk, you should be looking for signs of drainage issues:  Water standing on the road, trapped water running down the road forming ruts, and water pooling in the uphill road ditch all indicate drainage issues that may leader to bigger more damaging (more expensive) problems.

Roads are an important asset for a woodland owner.  Roads give access to the woods by foot and or vehicle, for some or all of the year.  This allows for recreation, management activities such as planting, weed control or harvest, and also fire protection.  Roads are an important piece of a property’s infrastructure along with buildings or ponds, and represent a significant financial investment.

Like other assets such as your house, car, pond or barn, roads need to be maintained to keep their practical values noted above, as well as value of investment.  But in contrast to the buildings or other infrastructure on your property,  with a road, a woodland owner takes on some legal responsibilities to maintain them.  That is because, for all their benefits to a landowner, road systems also have the potential to do significant harm to the environment by creating barriers to fish passage or allowing erosion and delivery of sediment to streams. A forest landowner is expected to keep roads in good repair to prevent such harm to the environment.  The type, timing and intensity of maintenance will depend on the type of road, location, construction and its use:  A rock road used to haul logs down a valley in the winter is very different from a dirt road along a ridge with light seasonal use.

We’ve discussed ongoing drought stress a number of times on this blog.  But when do we consider it dry enough to be called a drought?  There’s actually a system for that. The United States Drought Monitor updates and releases a national map each week, showing which areas of the country are experiencing drought, and how extreme the conditions are.  A variety of data sources go into their models, which I won’t begin to explain here, but their website has a lot of good information on how they determine drought conditions. In fact, all the data and visual tools on the Drought Monitor website feed the data geek in me; so if you like this sort of thing I encourage you to check it out.

If it seems like this blog has been a broken record stuck on the drought track the last few years, you’re not imagining things. But today, I want to highlight that in northwest Oregon we begin 2019 in a state of Moderate Drought, according to the Drought Monitor (see figure below; click to enlarge), even though we are in the midst of the rainy season.

Holly foliage usually (but not always) has sharp, prickly lobes.

Rid your land of English holly

Fa-la-la-la-la, la-la-la-la

Tis the season to spot holly

Fa-la-la-la-la, la-la-la-la

When all the other leaves are gone

Fa-la-la, la-la-la, la-la-la

Holly’s deep green stands out strong

Fa-la-la-la-la, la-la-la-la

Ok, there’s a good reason I didn’t become a songwriter. The point I want to make, though, is that this is a great time of year to scout your woodland for a common and nefarious invasive plant: English holly. It stays green all year long, so now that herbaceous plants have died back and other shrubs have lost their leaves, it’s easier to spot. Continue reading

As you know I am an outspoken advocate of thinning woodland stands, suggesting that for many (not all) family landowners “thin early, thin often” is the path to the future forest they envision.    Amy and I have posted numerous articles illustrating the many reasons for and benefits that thinning provides to family forest landowners.  This single practice applied with purpose, at the appropriate times, can shape a young forest into a uniform timber stand…. or a complex and chaotic habitat for wildlife.  The choice is really up to you.

 

OSU Extension released a new publication this summer to help landowners better understand, visualize and apply thinning decisions to their properties.  Competition and Density in Woodland Stands  EM 9206  describes in some detail the effects that different levels of competition has on a developing stand of trees, introduces Relative Density as  a way to determine the level of competition, and presents a unique new style of stand density table as a way to apply this information in the field.    The publication provides examples of how the tables can be used in determining if, when and how many trees to remove in a thinning, according to the objectives of the landowner.  It includes printable stand density tables for six different Oregon tree species.

Make this publication part of this winter’s reading list.

I’ve been taking part in an OSU Extension program called Oregon Season Tracker (OST) for about five years.  OST is a citizen science program where volunteers keep track of rainfall and plant phenology (seasonal growth patterns) and submit their records to national databases.  OST also connects natural resources managers, landowners, educators, and others in the community with researchers and their science.  At our office in St. Helens, we have an approved rain gauge which we try to check each morning, and a phenology “garden” consisting of two large Douglas-fir trees and some native shrubs.

When I first got involved in OST, my motivation was practical. I thought that having some consistent record of weather and phenology patterns would ultimately be useful in my work in Forestry & Natural Resources Extension.  I wasn’t quite sure exactly how it would be useful. But I figured that since weather affects trees in many ways, something would come of it; and even if not, I would be helping scientists with THEIR research questions. Continue reading

This year’s fires in eastern and southern Oregon, and especially California remind us that fire does not occur only in remote forest areas.  It is common in rural areas, can affect farm lands, communities along the wildland-urban fringe, and can even cross the boundary into densely developed communities.

The scale and intensity of fires across the west are increasing for many reasons including historic land management and fire exclusion policies, development patterns and recent climate patterns resulting in many consecutive years of intense droughts.  It is important for people in western Oregon to realize that we too live in a fire landscape, even though it is not as common as elsewhere in the state.

An Interview with Cory Garms, PhD Student – Oregon State University

Edited by Lauren Grand, OSU Forestry & Natural Resources Extension Agent – Lane County

Drones are becoming more popular to use in forestry. With recent innovations, small landowners are beginning to gain more affordable access to this useful new technology. I spoke to Cory Garms, a PhD student at Oregon State University, about what small acreage landowners might want to know about using drones to survey their own property.

Often around this time of year, I’ll get a question from a small woodland owner asking whether it’s worth the trouble to try to water their newly planted tree seedlings. My standard reply has always been “No”.  Of course, in most cases, it’s not even a practical consideration, because the logistical challenges of delivering water to hundreds, if not thousands of seedlings on steep or rough terrain far from any water source far outweigh any potential benefits.  I also point out that our Douglas-fir trees are adapted to withstand dry summers. After all, millions of Douglas-fir trees are planted each year in Oregon, and most of them make it without any supplemental water. And, I know one or two woodland owners who have watered trees that they were concerned about, only to have them die anyway.

But this year, after fielding the question of watering young trees again, I started to think a little more about my standard answer. After all, all signs are pointing another drought year. Scientists predict that summers in the Pacific Northwest are only going to get hotter and drier in the future.  In light of these factors it doesn’t seem like an unreasonable question.
