Ecology and Forest Classification Quiz

Forest and Ecology

• Tarn rorest land includes areas recorded as forest in government records, regardless of ownership.
• Save a tree; please don't print this unless you really need to!

Plant Nutrition

• Iron is a macronutrient, primary nutrient, and secondary nutrient in plant nutrition.

Forest Crops and Silviculture

• The art and science of cultivating forest crops is called forest culture, monoculture, or silviculture.

Climax and Primary Succession

• A climax caused by wildfires is an example of catastrophic climax, not climatic climax.
• The correct sequence of lithosere primary succession is: Rock → Crustose lichen → Foliose lichen → Moss → Shrub → Woodland → Climax.

Forestry and Productivity

• The study of life history and general features of forest crops with respect to environmental factors is called forestry or silviculture.
• Practical application of scientific, technical, and economic principles of forestry comes under forest mensuration, not forest protection.
• Net primary productivity is given by APAR x LUE.

Soil and Weathering

• Regur is a type of alluvial soil, not red and yellow soil.
• Carbonation is an example of physical weathering, not biological weathering.
• Bangar is a type of black cotton soil.
• Cryofracturing is an example of physical weathering, not chemical or biological weathering.
• In soil profile, C refers to the organic surface layer, not topsoil or subsoil layer.
• Vertical arrangement of soil horizon is called soil profile, not soil texture.

Forest Measurement and Sampling

• For a tree with dbh = 45.6 cm, height = 27 m, and total stem volume of 1.78 cum, the artificial form factor for the tree is: 0.1.
• The correct statement is: For a non-circular cross-section, girth tape under-estimates the sectional area.
• A tree has dbh of 25 cm, and its basal area is 0.049 m².
• Systematic sampling employs a simple rule of selecting every k-th unit starting with a number chosen at random from 1 to k as the random start.

Forest Types and Values

• Tropical moist forests do not include semi-evergreen forests.
• The value derived from the knowledge of use of resources by others in the current generation is called bequest value.
• Montane sub-tropical forests do not include broad-leaved forests, pine forests, or dry evergreen forests.
• The term 'forest' originates from Latin "foris," meaning outside or forest, not Greek "lons" meaning trees.

Surveying and LiDAR

• Plane surveying takes into account the true shape of the Earth and is used for smaller areas (< 250 sq km), not larger areas (> 250 sq km).
• Geodetic surveying takes into account the true shape of the Earth and is used for larger areas (> 250 sq km), not smaller areas.
• IMU stands for Inertial Measurement Unit, not Imperial metering unit or Imperial measurement unit.
• The time of flight for LiDAR is 0.001 sec, and the distance of the object from the instrument is 150 m.

Wildlife Protection

• In the context of the Wildlife Protection Act 1972, the trap is a weapon, and capturing is hunting.
