|Trees for Problem Landscape Sites -- Air Pollution||
Conditions in urban environments place trees under numerous stresses including compacted soil, soil moisture extremes, and reduced soil fertility. Polluted air is another stress that contributes to the decline of urban trees. Air pollution may cause short-term (acute) damage, which is immediately visible, and long-term (chronic) damage, which can lead to gradual tree decline. Long-term damage may predispose trees to other disorders, making diagnosis difficult.

|Trees for Problem Landscape Sites -- Screening||
Using trees as living screens can easily enhance living and working spaces. Before selecting trees for screening, first determine the screen's purpose, whether functional or environmental. Screening can be used to define an area, modify or hide a view, create privacy, block wind, dust, salt and snow, control noise, filter light, and direct traffic flow.

|Trees for Problem Landscape Sites -- Trees for Hot Sites||
Hot landscape sites require special consideration before trees are planted. Trees can survive, and even thrive, in hot sites if the site is prepared correctly, if heat-tolerant species are selected, and if the trees are properly maintained. A variety of different locations and situations qualify as hot landscape sites.

|Trees for Problem Landscape Sites -- Trees for Landscape Containers and Planters||
Planting trees in aboveground containers and planters is becoming a common practice on sites that are not suited for inground planting. Containers differ from raised planters in that they are usually smaller in volume and moveable, whereas planters are generally larger, and often built as part of the permanent hardscape (paving, etc.). The greatest challenge in selecting trees for containers and planters is in choosing trees that can survive temperature extremes, and that can establish roots in a limited volume of substrate (potting soil). Consider several factors when selecting containers and trees including environmental influences, container and planter design, substrate type, and tree characteristics.

|Trees for Problem Landscape Sites -- Wet and Dry Sites||
To grow, all trees require air, light, water and nutrients. Some trees can survive over a wide range of climatic and soil conditions, whereas others are very site specific. Both wet and dry sites present establishment and growth challenges, making selection of the right tree for the right site very important.
Know the site's soil
When selecting trees relative to soil moisture, begin by identifying the site's soil type. Soil maps are available for most areas in Virginia (contact your local Virginia Cooperative Extension office). Keep in mind, however, that construction activities (compaction, cut and fill, topsoil removal) may have altered the native soil.

|Virginia 4-H School Enrichment: Forestry||
Extension agents and volunteers should not hesitate to start a program in forestry because of a perceived lack of knowledge. There are forestry professionals in every county, and most realize that attitudes of youth will profoundly affect the future of forestry. The following six lessons were selected because they represent activities that youth enjoy, and they lead to other 4-H projects and activities. All of them match SOLs for the suggested grades.
