Study Notes

Introduction to Data Collection

  • Data collection involves gathering information for analysis, interpretation, and informed decision-making
  • Accurate data collection in natural resource monitoring and inventory ensures efficient and sustainable resource management

Importance of Data Collection

  • Helps track changes in the environment over time
  • Supports decision-making in conservation and policy
  • Identifies trends and patterns in resource use
  • Provides a scientific basis for environmental action

Simple Data Collection Techniques

  • Observation, tallying, and measuring are fundamental tools in natural resource monitoring and inventory
  • These techniques provide essential data for environmental sustainability and decision-making

Observation

  • Directly watching and noting changes in a particular environment or resource
  • Researchers record visual details about the subject, such as tree health, air pollution, and wildlife behavior
  • Observation can be done qualitatively (descriptive) or quantitatively (measured with numbers)
  • Examples include observing forest conditions for tree density and deforestation signs, and observing water quality for turbidity, algae, or pollution
  • Pros: Easy to conduct, requires minimal tools, and provides real-time insights
  • Cons: Subjective, depends on the observer’s perception, and cannot always provide exact measurements

Tallying

  • Counting and recording the number of occurrences of a specific event or object over time
  • A tally sheet or checklist is used to mark observations
  • Often used for counting trees, animal species, or pollution incidents
  • Examples include counting the number of birds in an area over a set period and tallying plastic waste found along a riverbank
  • Pros: Simple and quick method for tracking numbers, useful for large-scale surveys, like wildlife population
  • Cons: Can be inaccurate if not carefully recorded, and it doesn't provide details beyond numbers
  • Sample tally sheet example: Plastic Bottles 110, Cans 38, Paper Waste 9000

Measuring

  • Using tools to collect numerical data on environmental parameters
  • Requires measuring instruments such as rulers, thermometers, pH meters, and GPS devices
  • Provides precise and objective data
  • Examples: Measures include tree height with measuring tape, air temperature with a thermometer, and water pH levels to determine pollution levels
  • Pros: Provides accurate and reliable data, helps in long-term tracking of changes
  • Cons: Requires tools that may not always be available, and needs basic training to ensure correct usage
  • Sample tally sheet example: Tree Height uses Measuring Tape, Water Quality uses a PH Meter, Temperature uses a Thermometer
