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.

Fire Season will soon be in effect in much of the Tree Topics reading area, as declared by the State Forester according to regional fire conditions (usually by early July). Here are some fire season basics to keep in mind:

To find out when an area is declared, you can visit the ODF Wildfire website and click on Forest Restrictions and Closures  section. There you can find links to an overview of the Industrial Fire Precaution Level (IFPL), closures and other information about fire regulations and restrictions.

If you choose the Current IFPL/Public Use (Regulated Closure) Chart you can find the fire level precaution for each of the ODF Forest Protection Districts by clicking on that district. Changes in precaution level and closures will be posted there over the summer, so it is a good idea to monitor this information throughout the season.

Please remember that even a Level 1 precaution requires you to carry fire equipment when in the woods. The motor vehicle or light truck (<=26,000 pounds GVW) requirements are:

  1. A) 1 shovel with a minimum 8-inch wide face and a minimum 26-inch length handle, ready for immediate use.
    B) 1 axe or Pulaski with a minimum 26-inch length handle, ready for immediate use.
    C) 1 approved A,B,C extinguisher, 2.5 pounds or larger (preferably 5 pound minimum), ready for immediate use.
    D) Exhaust system with muffler in good operating condition.

Be sure you, your family or others using vehicles on your property are aware of this.  I generally make it a habit to carry these tools in my vehicle all summer.

Additionally, if you are using a chainsaw, each saw must have a shovel (meeting above standards), ready for immediate use; an 8-ounce (larger preferred) fire extinguisher, ready for immediate use; the standard exhaust system (spark arrester screen) must be in good operating condition; and the operator must stop the saw before fueling and move the saw at least 20 feet from fueling location prior to starting.

Please be FireWise, alert, aware, and pro-active in fire prevention. Be aware of how and where you park your vehicle, since exhaust system components have been known to ignite dry grass.  We’ve had a number of reminders recently that western Oregon is primed for wildfire each summer.  You don’t want to be part of the next one.

We have been dedicating a fair amount of screen space and class time lately to the idea that many family forest landowners would benefit from thinning their young stands. We explored the reasons to consider young stand thinning (YST) as well as some approaches in a series of posts on YST .  YST is consistent with the situation and goals of many family forest landowners, which often include growing older and more diverse forests.

That said, like many other well-grounded activities, YST is not without some potential drawbacks.

Few of them are significant enough to justify not thinning at all, but each requires some thought and consideration to avoid unintended consequences. We present some of those potential drawbacks that you need to consider when planning a YST, along with some links to other information, below. Continue reading

In this series about young stand thinning , I’ve worked on the assumption that people know the density of trees in their woods. I realize that in many cases, people don’t really know that, so cannot easily apply that information to deciding if they have enough room for healthy growth or if trees need to be thinned.

If you know what distance the trees were said to have been planted, you may have a fair idea of the density (a 10’ x 10’ spacing is about 440 trees per acre, a 12’ x 12’ is about 300 tpa). This is a good start, but not necessarily very accurate.   Actual planting spacing can vary quite a bit according to the conditions in the field and experience of the planters.  And of course some seedlings die during establishment, or some other trees may seed in from outside.  So it is probably a good idea to go out and get a better idea of what you’ve got.  The basic way to do this is to measure some plots.

We often hear from landowners that that they want a diverse, natural-looking forest. Their reasons vary.  Some folks are aware of the many ecological benefits that diversity brings to a woodland property, while others may have been inspired by the beauty of an old growth forest.

Of course, it takes centuries for an old growth forest to develop and many of our readers have young stands planted within the last decade or two that may look more like this:

So how do you move from one situation to another?

Happily, a landowner has many ways to influence and encourage diversity in their woodlands. Even if you have just bought some recently cut-over land, it does not have to remain a simple timber plantation if you do not want it to be.  You can grow a diverse forest.  And it can be done within decades rather than centuries.  No, it will not be old growth, but it may help reach many of the diversity-related objectives landowners commonly mention, including an attractive forest setting, better habitat for a variety of animals and a resilient forest.

A network of paths leads from any starting point in a woodland’s development. Each crossing is an event or decision that leads in a different direction and towards a different woodland condition.

In this series, we will be exploring the pathways to a diverse forest in western Oregon. These ideas also apply to an oak woodland, a riparian forest as well as an upland conifer-dominated forest.  In our next post we look at what makes a forest diverse and why it matters.  In later posts we will consider turns you can take throughout the life of the forest to restore, enhance and maintain woodland diversity to match your particular objectives.

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)

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.
