One of our visits was to a cooperative forest jointly owned by about a dozen families from Bengtshedens village. The Mellanskog landowner cooperative also has a significant share of ownership.

Dalarna County was the seat of a very old and important copper and iron mining industry, an early source of wealth and power for Sweden. We visted the Falun copper mine, active since the 10th century and a UNESCO world heritage site.
Why is that part of our forestry tour?
Forest products were a critical part of early mining industry, which needed massive amounts of charcoal and round wood to extract and process the metals. Forestlands near the mine were hard pressed to provide these products. The mine is also the birthplace of world’s oldest stock company, which eventually became large forest and paper corporation Stora Enso.
Over-exploitation of forest resources by the mid-16th century led to a series of perhaps the world’s oldest forest protection rules. In 1607 King Charles IX issued a ban on logging and charcoal production within a one-mile radius of the Falun mine (using the old Swedish mile, about 7 English miles). It was named the “Peace Mile” in hopes it would reduce disputes over unregulated charcoal production.
However it was not until 1754 that the surveyor Johan Brandberg finished measuring 112 points around the circumference of a the circle, marking each with stones.

A New Approach
Dalagård farm & forest retreat is a large working forest owned by Cecilia and Leif Öster. These first -generation landowners are developing an active silvo-trouism enterprise to diversify the farm’s income and promote its sustainability. Forest products and hunting leases are other significant income streams.

Our group of 26 family woodland owners arrived in Sweden this week at the start of the Scandinavia Forestry Tour.
The tour is organized by the Oregon Woodlands Coop along with Washington County Woodlands Association and OSU Forestry &
Natural Resources Extension.
The purpose of the tour is to look at forestry practices in this part of the world, meet fellow family forest landowners and focus particularly on the strong role of landowner cooperatives in both Sweden and Norway.
Most of our group is from Oregon, but we have people from four other US states, as well as South Africa rounding out the group.
This is my first electronic post card from the tour, where I will try to share some of the things we are seeing and learning here.

Conifer trees around the Valley continue to show signs of severe drought and heat stress this year. This should not be news to many readers: young dead trees are now a common sight throughout the Valley. Also, I wrote about this problem in past Tree Topics blogs (See stories from May and September 2015 for background) but have new updates for this season.
I think you can expect to continue seeing similar damage to Douglas-fir this year and that symptoms will continue to unfold as the season progresses. Some of the trees damaged late last year did not show that damage immediately. The damage did not become evident until the trees came out of dormancy and began to grow this spring. Also, the various insect and disease organisms that take advantage of weak and damaged trees are likely to continue with their business this year, causing new signs of drought damage to show up during the season. Happily, those players like Douglas-fir cankers and twig weevils do not typically blow up and kill healthy trees. This suggests things will look much like what we saw and described last year and is likely to continue to unfold this season and maybe longer, whatever weather we get. “It is important to understand that the effects of drought damage do not go away suddenly when the rain starts again” cautions Christine Buhl, ODF Forest Entomologist “drought can impact the tree’s whole plumbing structure, and affect the growth and vigor of the tree for years.”

In previous segments I argued that many people have too many trees in their young stands which may be costly and harmful to the long term growth of the stand. Most importantly, having too many trees at this stage can undermine common landowner objectives of growing attractive, longer rotation diverse forest habitats and can force landowners into shorter rotations than imagined.
While this suggests that people should think about planting fewer trees per acre in the future (a step deserving some careful consideration), it highlights the need for thinning in many existing young stands to correct overstocking at an early age. This may include your stand.

Pretty much every landowner I know has a weed issue.
Some are fairly short term and narrow, such as controlling common weeds in a new tree planting. Others are much longer term and less defined, such as keeping invasive species at bay in the woodland, or perhaps encouraging native plants in a meadow or streamside restoration.
There are multiple approaches to weed management, including preventing new weed introductions, mechanical or physical control such as mulching or mowing and the use of herbicides. Most people use a mix of two or more of these approaches, with many including herbicides as one of the methods they use.
Here are some key resources to help you manage your weed issues.
Invasive Weed Identification and Management EC 1563
It is important to know the enemy, and this is a good place to start, beginning with the 3-page introduction. This publication goes on to describe the identifying characteristics, origin, habitat, ecology and management strategies for selected invasive weeds in the Pacific Northwest. This list is not inclusive of all invasive weeds, but focuses on the most dominant or potentially invasive species that plague us. Check PNW Weed Management Handbook for current herbicide recommendations.
The Nature Conservancy’s Weed Control Methods Handbook
A useful resource for many types of landowners, the Weed Control Methods Handbook: Tools & Techniques for Use in Natural Areas provides detailed information about weed control techniques including manual and mechanical methods, grazing, prescribed fire, biological control, and herbicides. Check PNW Weed Management Handbook for current herbicide recommendations.

In my travels around the mid-Willamette Valley, I am seeing a lot of young conifer stands (generally Douglas-fir up to 20-something years old) with just too many trees. Why do I say there are too many trees?
I know many people in this part of western Oregon who are patiently waiting for their trees to grow, hoping to thin the trees in a selective harvest when the stand is about 25 years old. They plan to sell the harvested trees to cover costs and would like to break-even or make a bit back on establishment expenses.
All too often it is not working out that way. Instead, as the stand approaches the target age they find that trees have already become too crowded, with too many small, slow growing trees in the stand. The trees are still too small to support a profitable harvest thinning operation (also called a commercial thinning). To thin at that point is to do so at a cost, although it may be best for the woodland in the long-run. To delay the thinning and wait for the trees to grow enough to make the thinning harvest profitable is appealing, but deceptive. It may avoid the short term expense, but is likely to weaken the stand at a long-term cost of growth, stand stability and future options. It is a classic “pay now or pay later” situation.

“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

At our home, my wife has resolved to work on emergency preparedness this year. Sure, we have a pantry full of food, jugs of water, flashlights and batteries. Heck, anyone living in a rural area keeps those things on hand for comfort in semi-regular storm events.
But how about the really big events or when something very different, like a wildland fire happens? Are you and your family ready? Continue reading
