Tree Care Handbook
Minnesota SWCD Forestry Association Tree Handbook Dear Tree Planter. With headlines reporting the continuing deforestation of the tropical rain forest, one may ask the question: Are America’s forests in danger of disappearing? Because people such as yourself practice reforestation, our forested acres are actually growing in size. About one-third of the United States, or 731 million acres is covered with trees. That’s about 70 percent of the forest that existed when Columbus discovered America. Almost one third of this is set aside in permanent parks and wilderness areas. Minnesotans’ have planted an average of 12 million trees annually; enough trees to cover over 15,000 acres per year. Good land stewards are planting trees for many good reasons. The results of their efforts can be seen in reduced soil erosion, improved air and water quality, healthy forest industries, enhanced wildlife habitat and generally a more attractive surrounding for us to live in. Aspen has become the most prominent tree in Minnesota’s forests. After clearcutting, aspen regenerates readily by sprouting from its root system or by drifting seeds onto disturbed sites. Most of the other major species in Minnesota need some help from tree planters to ensure that they make up a part of the new forest. The following pages will help explain how to plant and care for a tree seedling. There is a section on the general characteristics and planting requirements of the tree and shrub species commonly planted for conservation purposes in Minnesota. The professionals working in conservation throughout Minnesota thank you for planting, nurturing and wisely using one of Minnesota’s greatest treasures its renewable trees. -

Sustainability Report for Georgia's Forests
Executive Summary Georgia’s forests are being sustainably managed to meet the numerous needs of our state today. To ensure our forests will continue to meet the needs of present generations and the projected demands for future generations, many challenges must be addressed. Forest sustainability is dependent on both environmental and economic sustainability. A challenge to either element is a challenge to both elements. Success will depend on proactive decisions by our state leaders and the entire forestry and conservation communities addressing a myriad of forestry-related issues. Georgia boasts more than 24 million acres of forestland. Georgia’s forest inventory volumes are at an all-time high. We have 49 percent more cubic feet of wood growing in Georgia than we did 40 years ago. However, the state’s population is increasing at a record rate. Urbanization continues to be a threat to forest sustainability. Further, recent increases in population and changing land-use patterns have made ongoing forest management more difficult in some areas of the state. These and other trends threaten forest sustainability and the numerous economic, environmental, and social benefits that our forests provide. This report describes both forestland (all forests including those not available for commercial harvest – 24.6 million acres) and timberland (all forests that are available for commercial harvest – 23.9 million acres). (GFC 2016) Georgia’s forest area has remained stable over the past 50 years at about 24 million acres. Approximately 91 percent of this acreage is privately owned, giving Georgia more privately-owned acres of timberland than any other state in the nation. -
Whoosh Bottle
Whoosh Bottle Introduction SCIENTIFIC Wow your students with a whoosh! Students will love to see the blue alcohol flame shoot out the mouth of the bottle and watch the dancing flames pulsate in the jug as more air is drawn in. Concepts • Exothermic reactions • Activation energy • Combustion Background Low-boiling alcohols vaporize readily, and when alcohol is placed in a 5-gallon, small-mouthed jug, it forms a volatile mixture with the air. A simple match held by the mouth of the jug provides the activation energy needed for the combustion of the alcohol/air mixture. Only a small amount of alcohol is used and it quickly vaporizes to a heavier-than-air vapor. The alcohol vapor and air are all that remain in the bottle. Alcohol molecules in the vapor phase are farther apart than in the liquid phase and present far more surface area for reaction; therefore the combustion reaction that occurs is very fast. Since the burning is so rapid and occurs in the confined space of a 5-gallon jug with a small neck, the sound produced is very interesting, sounding like a “whoosh.” The equation for the combustion reaction of isopropyl alcohol is as follows, where 1 mole of isopropyl alcohol combines with 4.5 moles of oxygen to produce 3 moles of carbon dioxide and 4 moles of water: 9 (CH3)2CHOH(g) + ⁄2O2(g) → 3CO2(g) + 4H2O(g) ∆H = –1886.6 kJ/mol Materials Isopropyl alcohol, (CH3)2CHOH, 20–30 mL Graduated cylinder, 25-mL Whoosh bottle, plastic jug, 5-gallon Match or wood splint taped to meter stick Fire blanket (highly recommended) Safety shield (highly recommended) Funnel, small Safety Precautions Please read all safety precautions before proceeding with this demonstration. -

The road that led us to that vision began decades ago as we responded to consumer trends with the launch of snus in pouch format in 1973, thus reinvigorating the snus category. We took a further step down the road when we divested the cigarette business in 1999. This journey has continued more recently through our focus on smokefree alternatives in new formats, new categories and in new geographies. Swedish Match continues to adapt and raise the benchmark, in quality, performance, and consumer satisfaction for its smokefree products.

Harvesting Firewood from Your Woods
Harvesting Firewood from Your Woods TOPICS: n Tree and Forest Biology (page 2) Basic concepts about how trees grow and the characteristics that make trees good or bad for firewood n Planning a Harvest (page 8) Which trees to cut for firewood and how to cut them safely n Processing Trees into Firewood ( p age 14) Techniques for splitting, drying and stacking wood Tree & Forest Biology Cutting trees for firewood requires careful management. The management decisions you make can either improve or harm the long-term health and productivity of your woodlands. Understanding how and where trees grow can aid your deci- sions about which trees to cut, and will lead to improvements in the overall health of your woodlands. Trees have several basic requirements for long-term survival: nutrients, space, water and sunlight. The competition for these resources will determine how well a tree grows and how long it will survive. Tree roots are responsible for the uptake of water and nutrients. The quality and quantity of these nutrients vary depending on the soil. Different trees are adapted to the dif- ferent soil types, from sand to clay. Clay and loam soils hold water and nutrients better than sandy soils. That means trees growing on sandy soils need to be able to grow in low nutrient and low moisture conditions. Each soil type can only support a limited number of trees, based on their size. Trees become stressed when there is too much competition for water and nutrients. To keep your forest healthy, some trees should be removed to make room for others to grow.
