Research & Extension Center Oct-Nov-Dec. 1999 Fire Prevention News
Its the time of year when cool outside temperatures cause us to turn on our heating systems. They make our homes warm and cozy, but they also are a leading cause of fires. Have all heating equipment, including chimneys, serviced each year by reputable professionals. Keep anything that can burn at least three feet away from any heat source. Use portable heaters only if they call the UL label and only if they have sturdy cords. Never use an extension cord. Use only 1K kerosene in kerosene heaters. Fill them outside and use them only in well ventilated rooms. Never leave portable heaters unattended. Be careful - keep your family warm and safe at the same time. Have a Spooky and Safe
Halloween Late autumn and early winter are festive fun-filled times for family fun. However, the bustle of holidays tends to generate carelessness. This is a time of opportunities for fires to occur. It is also a time for increased activities by Fire Prevention committees. The first fun fall holiday is Halloween. It is a time for carving a frightful jack-o-lantern and planning that perfect costume. Its fun-filled parties with friends and visiting neighbors to gather Halloween treats. Yet each year, many children are injured and killed as a result of fire. Costumes, pumpkins, treats and scariness are all part of a fun Halloween. Witches and ghouls make the horrible fun, but there is not a place for real tragedy on this or any night. The Nebraska Forest Service/Fire Control Section reminds you of some tips for a safe Halloween. Windbreaks, Woodlands, and Trees Community Forestry: 999 Trees N Town Conference - November 4-5 at the Midtown Holiday Inn in Grand Island will focus on public entities. Some of the topics to be presented include plant selection for harsh environments, trees to improve the community, design of public buildings and spaces, and managing public ecosystems. In addition there will be advice on pruning and maintenance of public landscapes. This program should appeal to anyone who is involved in forestry and green space projects in their communities. There is something for tree board members, park managers, city administrators, volunteers, and anyone else interested in creating successful landscapes. Registration for the conference is $75.00 per person and includes conference materials, refreshments, lunch and dinner on Thursday. Entertainment on Thursday evening will be provided by Nebraska musical folk artist Chris Sayre. To register for the conference, contact the Nebraska Statewide Arboretum at 402-472-2971. There are also scholarships available. Contact Dave Mooter at 402-444-7804 for scholarship information. Lodging is available at the Midtown Holiday Inn in Grand Island. They are holding a block of rooms. To make reservations call 800-548-5542; mention the Trees N Towns Conference. Rural Forestry: 1999 Region Woodland Stewardship Conference The second annual "Central Region Woodland Stewardship Conference" (Iowa, Nebraska, Kansas, Missouri) will be held Saturday, November 20, 1999 at the beautiful Arbor Day Foundations Lied Conference Center in Nebraska City. Due to the resounding success of the first conference in 1998, the 1999 event will again be held in Nebraska City. The Central Region Woodland Stewardship Conference is sponsored by State and Extension Forestry in Iowa, Kansas, Missouri and Nebraska. The conference is designed to provide landowners in the 4-state area with the knowledge and skills to manage their woodland and related resources using good stewardship principles. The 1999 conference format will be similar to last years, with four concurrent sessions presented each hour during the day-long event. The conference will begin at 9:00 a.m. with registration and refreshments and adjourn at 4:00 p.m. Concurrent session topics for the 1999 conference include:
Registration will be held to $25, which includes a buffet luncheon and continuous break. For more information or a conference brochure, contact Steve Rasmussen at 370-4024, John DuPlissis at 371-7313, or Dennis Adams, Nebraska coordinator, at (402) 472-5822 or e-mail: dadams2@unl.edu Battle
Creek Street Tree Assessment-Two Inventory Earlier this summer, John DuPlissis (Northeast District Forester Assistant) inventoried the public trees in Battle Creek. Below is an excerpt from his assessment sent to the town evaluating the street tree resource: In 1990 the city of Battle Creek had 637 street trees. Of this number, 244 were green ashes compared to 212 in 1997. In 1990 green ash and silver maple accounted for approximately 51 percent of the total population. Today these same species account for less than 45 percent of the total population. This is a modest but important decline. In 1990 there were 34 different species recorded compared to 43 in 1997. In the 7 years between inventories the street tree resource in Battle Creek has grown both in numbers and species diversity. Also, the actual value of these trees is greater as well. The overall value of the street tree resource has nearly doubled in that time climbing from $1,294,000 to $2,320,000. This figure does not include the value of the trees in the City Parks Parks of Pride Arboretum which are valued at $477,000. The formula used to estimate the value of street trees used exact same dollar amount ($27.00) for 1990 as it did in 1997, therefore, this difference may be even greater after adjustments for inflation are made. Based on these two inventories it is apparent that the city of Battle Creek has a street tree resource that reflects the pride, hard work, and determination of past mayors, council members, employees, and Tree Board members. However, trees are living and growing organisms and unless the Tree Board members and city government and employees show that same commitment your citys tree resource will surely go from above average to average or less. The inventory in 1990 estimated there were 637 trees (50% inventory method) compared to the tallied 693 trees (100% inventory method). This shows an increase in street trees in Battle Creek. This is a wonderful and quite honestly somewhat unusual since nationwide we are losing community tree numbers. Battle Creek has done a great job in helping retain (and add) trees in the community. The residents there now and for generations will have a nicer and more welcoming environment to live in. Has your community been working on improving or adding to its tree resource? Or has your town lost trees and is doing nothing with the tree resource. If you want your community to be an attractive and welcoming place to work and live in, contact this office at 370-4024 to find out what tree related activities you can help initiate or sponsor. I will be glad to help. Also, if you want an assessment done on your public trees in your town, give this office a call to schedule an inventory. Pine Needles Turning Yellow-Brown is probably not a thing to get worried about Fall is the season for leaves to turn from green to an assortment of colors. Green ashes to yellow and white ashes to purple; maples to reds, oranges and yellows; cottonwoods to yellow and pine trees to brown...what, wait a minute!! Yes, pine leaves (needles) will at three years (sometimes two years) of age mature and drop off the trees. Some years this is more noticeable than other years and some pines will show this more obviously than other pines. The interior needles are the oldest and will be the needles to eventually turn yellow to brown and then fall off! That is how a "carpet" of needles accumulates under older pine trees. In some parts of the country, these needles are harvested and sold for mulch. If your pine trees have interior needles turning brown this time of year, dont worry. It is probably natural needle drop. If the very outer needles are turning brown, that could be a sign of stress or an insect/disease problem and should be investigated. In most situations, needles turning brown this time of year is natural and can be ignored. After the first heavy, wet snowfall, they will be off the tree.
The late summer and early fall have been unusually dry in most parts of northeast Nebraska this year compared to recent past seasons. I measured one crack in my back yard the other day and it was 0.5 inches wide and eight inches deep! When I watered my apple tree, after two hours of running the hose at one half volume there was no ponding of water. The water had run into the cracks and gone....somewhere! We have been dry and shrubs and trees will need additional water now to help prepare them for this winter. This is especially important for newly established plants (less then three years old). For best results, water the plants slowly with a soaker hose around the drip line of the tree or a hose on one half to one fourth volume. Allow the area to get a deep soaking. On established trees, have the hose away from the trunk of the tree more out to the dripline (edge of the branches). This is where there is more of a concentration of tree roots that can make use of the water. Another very beneficial action that can be done for the tree or shrub is to mulch an area out to the edge of the branches with wood chips. This will help retain moisture and insulate the ground to protect the roots from early deep freezing temperatures. Apply the woodchips 2-4 inches deep and keep away 2-4 inches from the stems of the trees/shrubs. Watering and mulching are two actions you can do for your tree/shrub friends to help them through the difficult conditions the Great Plains has in store for these plants in the next four to five months. Recent years have brought to our attention the anxiety that the world is facing regarding the Y2K issue. Nobody is certain what the outcome will be - will all the problems be fixed in time or will lifestyles change? Some people and organizations have made it their goal to fix this problem in time and allocated millions of dollars to this cause. Take some time and think about this historic occasion and how fortunate we are that we will witness the passing of the millennium. As we prepare ourselves to step into the next year, ready to face the new challenges, think about doing something which will be remembered in 2100. Plant a tree. Think of memories for which you would want to plant a tree. Trees have longer lives than humans, often living hundreds of years. Seek professional help while planting trees since this is the most important process that determines their future. Taking care of your trees will also help them to live a longer, healthier life. Here are some benefits for which generations to come will thank you. Trees:
Trees are the guardians of nature and help provide a healthy living environment. If you are not sure about the health of your trees, a competent, professional arborist can offer diagnosis and suggest preventive maintenance plans to keep your trees in top condition and help you make the right decisions for the health of your trees. When planting, they can also help you select the correct tree species suitable for your area and implement the most effective planning techniques. (Source: National Arborist Assoc.)
A study examining world timber markets suggests that preservation efforts in North America and Europe could lead to increased deforestation in threatened tropical forests. The study predicts the loss of 1 hectare (2.47 acres) of previously inaccessible forest in Asia, South America, Africa, and the former Soviet Union for every 20 hectares set aside from timber harvesting in North America and Europe. "A small amount of forest conservation here can have negative worldwide effects," said Brent Sohngen, coauthor of the study and assistant professor of agricultural, environmental, and development economics at Ohio State University. "North America currently produces 35 percent of global timber. Conserving only 5 to 10 percent of timberland in a region that supplies such a large proportion of global harvests will increase harvests elsewhere, including tropical forests that at present are inaccessible." Many scientists are concerned about the possible ecological implications of the decline of tropical forests: the loss of biodiversity and undiscovered species, increased soil erosion, and the reduction of plants that remove CO2 from the atmosphere. Sohngen conducted the study with Robert Mendolsoh, a professor of forestry at Yale University, and Roger Sedjo, a senior fellow at Resources for the Future in Washington, D.C. The results were published in a recent issue of the American Journal of Agricultural Economics. The researchers developed a variety of models that examined how worldwide demand for timber might affect the conservation of forests across the globe between 1995 and 2135. They examined both current and predicted global timber supply, demand, prices, and harvest costs. Their analyses accounted for supply and harvest differences across several geographic regions and compared regeneration and forest development costs. Part of the researchers model examined two possible scenarios. The first assumes 5 percent of North American and European forests will be preserved, and the second suggests 10 percent of these forests will be set aside. Both scenarios predict that these set-asides would increase worldwide timber prices by 1 to 2 percent, while increasing timber harvests in other parts of the world by 1 percent. In the 5 percent scenario, the model predicts 1.4 million hectares of previously economically inaccessible forests will be harvested elsewhere. In the 10 percent case, an additional 2 million hectares of inaccessible forests will be harvested elsewhere. These additional timber harvests would likely occur in tropical areas, Sohngen said. According to Sohngen, simple economics helps explain why forest set-asides in North America and Europe may increase deforestation in the tropics and elsewhere.
