What is coefficient of wetness?

What is coefficient of wetness?

Coefficient of Wetness (CoW) The coefficient of wetness value indicates the plant’s soil moisture tolerance. The values provided in Figure 1 represents the type of vegetation community the species can tolerate under natural conditions.

What are shade intolerant trees?

Shade-tolerant species are species that are able to thrive in the shade, and in the presence of natural competition by other plants. Shade-intolerant species require full sunlight and little or no competition. Intermediate shade-tolerant trees fall somewhere in between the two.

What is a fast growth rate for trees?

“The designation slow means the plant grows 12” or less per year; medium refers to 13 to 24” of growth per year; and fast to 25” or greater.”

Are there only shade tolerant trees in climax community?

In fact, unlike their fast growing, short-lived, early successional counterparts – called “pioneer” species – whose seedlings tend to die in the understory, the seedlings and saplings of these “climax” species are very tolerant of shade.

Why are differences in shade tolerance important in succession?

A number of investigations focused on shade tolerance of saplings because the capacity of juvenile stages to survive and grow in low-light environments is important in plant succession (Kozlowski et al., 1991).

How fast do trees grow in diameter?

Dominant trees had the highest average annual increase in diameter (0.20 cm year−1 average, SE 0.03 cm year−1), followed by co-dominant trees (0.13 cm year−1 average, SE 0.02 cm year−1) and intermediate trees (0.06 cm year−1 average, SE 0.03 cm year−1).

What is a tolerant species?

Tolerant species are known for their ability to utilize a lower intensity of light than intolerants (Daniel et al., 1979). Tolerants intercept a greater pro- portion of the incipient light and their canopies are denser than that of in- tolerants.

How much will a tree grow in diameter per year?

Stacking time increases at a rate of 1.5 minutes per inch (2.5 cm) increase in tree diameter. The average growth rate is 0.50 inch (1.75 cm) per year.

Can Red Oak tolerate shade?

Reaction to Competition- Northern red oak is classed as intermediate in shade tolerance.

Is Beech shade tolerance?

Both fir and beech, as main coexisting species in montane, mixed-species forests, are shade tolerant, and could thrive under conditions of deep shade for longer time periods5.

What is the fastest-growing tree for privacy?

What are the fastest-growing trees for privacy? Hybrid poplar tops the list. It can grow upwards of five feet per year. The Leyland cypress, green giant arborvitae, and silver maple are all close seconds because they add about two feet to their height each year.
