Many landowners depend on professional operators to help get things done on their property.  This includes weed control. Finding the right person for the job is important. The process starts with knowing what you are looking for.

Like most forestry management practices, weed control is actually a mix of different activities. Depending on what you know and can do yourself, hiring a chemical applicator means you are actually looking to hire a mix of knowledge and skill, equipment and labor.

It is important to get this right. Otherwise you may waste money or injure your trees.  Worse still, it could mean causing damage to the environment or a neighbors’ crops, either of which would create a liability issue for you.

So how do you go about selecting the right chemical applicator for you? In conversations with some forestry professionals and landowners recently, it all boiled down to communicating about needs and expectations.  Here are some key questions and things to discuss before hiring a chemical applicator to work on your property.

Questions to ask potential providers: 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.

I was given Norwegian Wood this summer. No, not the Beatles’ famous 1965 single about a John Lennon romance.  The gift is a book about the Scandinavian romance with firewood.  Its full title is “Norwegian Wood: chopping, stacking and drying wood the Scandinavian way” (by Lars Mytting).  I loved it.  I would probably hesitate to admit that to most people, but Tree Topics and Compass readers are not most people.  You are wood people and will understand.  dscn5054

Norwegian Wood is an embrace of all things firewood. It delves into the historic Scandinavian reliance on wood to heat hearth and home when having enough wood on hand (at far northern latitudes) was a matter of life and death.  That dependence seems to still shape the collective Scandinavian psyche.  People there respect wood.

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)

We have certainly experienced some significant drought conditions lately.  Stressed and dying trees are showing up all around the Willamette Valley, with concern that this could lead to beetle outbreaks and still more trees killed.  Is it time to throw in the towel, cut your losses (so to speak) and just salvage everything that is looking poorly?  Maybe, maybe not.  The decision needs to be considered carefully, weighing individual sites and stand conditions along with your objectives for your property.  Anybody considering a salvage harvest needs to look before they leap.

DSCN3241Continuing on the general theme of young stand management and especially the need for thinning, I’d like to look at strategies for thinning a young stand. Let’s start with some things to keep in mind about Young Stand Thinning or YST (also called precommercial thinning or PCT):

  • The idea of young stand thinning (YST) is to avoid harmful overcrowding later by removing excess trees early on.
  • The impact of thinning out a tree is very local. The overall stocking level (trees per acre) can be misleading. It is the spacing among immediate neighbors that counts.
  • The greatest benefit of YST is increased growing space rather than selection among trees. Creating more growing space to benefit as many leave trees as possible is the primary goal. Culling is secondary.
  • YST is key to achieving longer rotations and many non-timber objectives many family forest landowners desire.

oceanspray floweringIf 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. Continue reading

Our final days of the tour included meetings with the local landowners’ cooperative in Telemark County and visits to two specialty sawmills.

The Tinnoset sawmill specializes in shaping large logs for traditional style log homes. Most are sold to builders, but they do some custom building on site too.

The Svenneby family sawmill has been working with leading architects and looking for less traditional uses of wood, including many exotic (USA) species. We lucked into a presentation by nationally acclaimed architect Einar Jarmund who talked about the expanding role and popularity of wood in both commercial and residential buildings in Norway and showed a number of projects done by his firm  ( http://www.jva.no/ ) using materials developed and delivered by the Svenneby mill.

We could not help but noticing how common and prominently wood was being used in Norway, and particularly as architectural and visual elements around Oslo.  Why does wood seem less used, less celebrated here?
