Slash is the term used to describe the treetops, limbs and other woody material left behind after a timber harvest. The amount of slash left behind will depend on several factors, including the size and quality of the harvested trees. Universally, how the slash is dealt with is an important consideration in the logging process. Heavy amounts of slash left on the ground can be a fire hazard and it makes tree planting more difficult and more costly.

Piling and burning is the most common method of slash treatment nowadays. However, some landowners are looking for alternatives to burning for various reasons. Pile burning can be challenging due to weather conditions or smoke restrictions. When logging contractors are busy, they may be reluctant to include pile burning in their contract due to the time involved, leaving it up to the landowner. And, there are greenhouse gas considerations with burning slash. For all of these reasons, it is worth looking at the pros and cons of other methods of slash treatment.

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.

Oregon forest landowners and Christmas tree growers are having difficulty locating seedlings to buy.

In response, the Oregon Department of Forestry, OSU Extension and other partners are working hard to identify and solve the problems limiting the supply. It’s not an easy fix; many pieces account for the problems and the solutions.

OSU Clackamas County Extension hosted a meeting in January to discuss the seedling supply. Landowners revealed that certain species or stock types are not always available within a year of planting. This presents some uncertain choices and potential compromise. One year plugs may be available in lieu of 1-1 transplants (2 year old seedlings). The 1-1 transplants have a fibrous root system and a track record of success in challenging conditions. However, future survival of one year plugs is uncertain. 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.

Last month I spent a morning at OSU attending the annual science meeting of the Vegetation Management Research Cooperative (VMRC). It was well worth the time.

The VMRC’s mission includes conducting applied reforestation research of young plantations from seedling establishment through crown closure and, to promote reforestation success. The VMRC’s research has an emphasis on practical, operational vegetation control, and their research is broadly relevant and readily applied to the needs of family forest landowners, so I do try to keep up on their work.

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.

I got a call a while back from someone having trouble finding the seedlings she wanted and wondering if she could make do with something else.

The caller wanted large, bare root hemlock seedlings from her Coast Range seed zone, but all she could find was container stock from a Washington seed source, and wanted to know if that was an ok choice.

Given the current seedling supply situation, I am thinking many people may be facing a similar choice between the “right” planting stock type and the “right” seed source, if they have any choice of seedlings at all.

When is compromise a sound choice? Continue reading →

Here is something you should know: Seedlings are in short supply for this winter’s planting season, and the situation is unlikely to improve any time soon.

So what is up? The seedling situation represents something of a perfect storm, with demand rising just as production is down. This is bad news for the folks who’ve noticed timber prices are up a bit and are thinking of a harvest sometime soon.

Remember those Magic 8 balls where you would ask a question, shake the ball, and get an answer? I wish life were that simple.

Extension agents get a lot of questions. Some say we are notorious for always answering with “well, it depends.” As an Extension agent I’m as guilty as anyone of using “it depends”, and not because I want to dodge your question. Usually there is more than one answer; more information is needed; and ultimately, you are the one who will be able to answer your own question after more a more thorough evaluation. Here is a sampling of inquiries I’ve received by phone, email, or Ask an Expert over the past few weeks, to illustrate this. Continue reading →

A free-to-grow tree coexisting with its early seral neighbors

Early seral…it’s one of the biggest buzzwords in Pacific Northwest forestry these days. But what is it? Put simply, early seral refers to the first stage in forest development following any disturbance, including wind, ice, fire or logging. An early seral, or early successional community is made up of the first colonizers of a forest opening: grasses, other herbaceous plants and broadleaf shrubs. Continue reading →
