What will the forests of the Boundary Waters look like in 10 years? 50 years? 100 years? In general there are two possible futures for the forest: unburned and burned.
In areas that don't burn, the seedlings that are already prolific in much of the blowdown area will quickly grow and fight to occupy the growing space that was created so suddenly last summer. Many of these seedlings were already around before the storm, waiting in the understory as what foresters call advance regeneration until the trees that hogged all of their light met their end. The windstorm gave the advance regeneration the opportunity of a lifetime, and these seedlings won't miss their chance. Before we know it, these seedlings will be trees, and the forest will soon look like a forest again.
Blowdown events are often said to speed the process of forest succession, because they favor species that are typically common in later successional stands. The species that existed as advance regeneration before the storm were those able to live in the shade of the forest floor. They are relatively tolerant of shade, and include species such as balsam fir, sugar maple, red maple, white spruce and white pine.
But there is another likely scenario: burning. With so much dead wood on the ground, there is a high likelihood that wildfires will burn at least part of the storm area. And these fires could be very intense. If so, they will consume not only the dead wood, but also any live seedlings, shrubs, and other vegetation in the area. In intensely burned areas, most of the trees that will dominate future stands will have to grow from seeds--to start from scratch on bare ground. Although they won't have the head start that the advance regeneration will have in unburned areas, in many areas these seedlings too will quickly grow and return the forestland to trees.
In some areas, it appears that the trees are growing on bedrock; there is little soil available. In these areas what soil exists is in the form of undecomposed moss and other organic matter. This will be consumed in an intense fire, leaving these areas barren for many years, until new soil can develop. This is the extreme case, and will not occur in all burned areas.
Fires, unlike blowdowns, return the forest to an earlier successional condition. Rather than speeding succession along, they set the process back to the beginning, where "pioneer" species such as aspen, jack pine, and birch will likely colonize and predominate. Red (or Norway) pine also regenerates well following fire.
Whatever the future holds, it will be fun to watch the forest change and develop. If you haven't yet, get off the trails and into the blowdown. You might be surprised at what you see. You just might find that the forest that was "devastated" and "destroyed" last summer is actually alive and well (and growing incredibly fast!) today.
We may have temporarily lost our postcard views, but we've been given a wonderful opportunity in exchange: to learn about how the forest works. Don't waste your opportunity indoors--get outside and have some fun learning from the best teacher we have, Mother Nature.

This article originally appeared in Oregon State University’s Forest Tree Notes in August of 1995. While the species discussed are different from Minnesota, the principles are the same.
The Taylor’s purchased ten acres near Bald Peak. The previous owner had harvested the merchantable timber two years previously and the area was pretty ugly, but, there were scattered maples and small fir trees on the site that still had aesthetic value. The area had also been replanted with 400 fir seedlings per acre. Although the seedlings were hard to see because of the brush and weeds that had invaded, the Taylor’s saw the potential and dreamed of a beautiful forest developing in the years to come.
Four years after the purchase they could no longer see the logging scars. Unfortunately, they couldn't find the planted seedlings, either. The brush was now dense and had choked out the little trees. They couldn't even walk over portions of the property. Some of the small fir that were left were now dead. The beautiful forest they had envisioned was not developing as they had hoped. The dream was now a bad dream. What went wrong? Anyone can find themselves in this situation. It is a far too common occurrence and not just a problem for owners of harvested land, but for those trying to convert fields and brushland, too. Unfortunately, there is a misconception that once you've planted trees they can take care of themselves.
There is not a successful farmer anywhere who prepares a field, plants the crop and goes on vacation until harvest time. The same is true for the successful gardener. The work really begins after the seed is planted. Many more hours are spent weeding and nurturing than in the initial planting. Similarly, the monitoring and maintenance that should be done after trees are planted is as critical as the planting itself, especially for the first few years. Aggressive invading weeds and brush can quickly out compete the frail newly planted seedlings.
An abundance of technical advice and information is available about reforestation through a variety of public and private sources. For more information, contact one of the Extension Educators in Forestry at the Cloquet Forestry Center at (218) 879-0850.
Deer, rabbits, gophers and other animals can stunt and kill seedlings and small trees.
Seedlings and small trees can be protected from animal damage using tree shelters, bud caps, mesh tubing and repellents.
Tree shelters: Tree shelters can be used to protect trees from beaver, deer, rabbits, small rodents and other animals. Tree shelters are sold in a variety of forms. Some are solid translucent plastic tubes or sheets rolled into tubes and placed around the seedling. Some are round plastic mesh tubes. The diameter of these tubes is generally 3 to 4.5 inches. They come in various heights from 2’ to 6’. They are held in place by a stake. A tree shelter protects the seedling until it grows out the top of the shelter. The shelter selected should be taller than the expected reach of the animal grazing on the trees. Different tree species react differently in the tube type shelters. Some trees such as the oaks may show a dramatic increase in height growth while other trees may be damaged by frost and disease. With any of the tree protection products select a few and try them to see what works for you, your trees and your specific site.
Animal repellents: Commercial repellents are available to help reduce browse damage. Some of these, clip onto the trees much like the “air-fresheners” used in cars, others are sprays. Often repellents must be sprayed several times per year to be effective.
Bud capping: Bud capping uses paper sleeves or plastic mesh to protect the terminal buds and top leader of the tree. The paper sleeves can be purchased or made. To make a paper bud cap, cut strips of paper 4 inches wide and 8 inches long. fold these in half length-wise over the terminal buds of the tree and staple.
Fencing: If deer browse is especially heavy, or if you want 100% control, fencing may be needed.

Driving Tour:
We are investigating the establishment of a permanent driving tour of various
sites that have been impacted by recent blowdown events in the Gunflint Region.
We would like to find sites that can be used to demonstrate forest regrowth
and clean-up activities. If you are interested in volunteering for this project,
please contact: Mike Reichenbach, Extension Educator at:

Thanks to the Northeast Region Sustainable Development Partnership, we have been able to produce this newsletter, and three workshops for private landowners during the summer of 2000. There will be one more issue of the newsletter this year. There are no more workshops planned for 2000.
We would like to thank all of the people who presented at the workshops, and those who provided materials for the newsletters. Their help is greatly appreciated.
It is our hope that through these efforts, private landowners gained some insight into the issues that federal, state and local agencies are dealing with after the 1999 storm. In addition, we hope that landowners have more information to guide the choices that they are faced with, and contacts to whom they will direct future questions.
The third issue of this newsletter is being sent to all landowners along the Gunflint Trail. Funding provided by the Northeast Region Sustainable Development Partnership was used to produce four issues of the newsletter. After the fourth issue, the newsletter will only be sent to landowners who request it.
If you would like to continue to receive this newsletter, please contact Susan Seabury either by mail at the University of Minnesota, Cloquet Forestry Center, 175 University Road, Cloquet, MN 55720, telephone at (218) 879-0850 ext. 108 or email at sseabury@umn.edu.
Also, PLEASE help us reduce costs further by providing us with an email address where we can send you an electronic copy of the newsletter.
