Biological Sampling

1. Training
   1. Professional technician at training
   2. Standardized training program with same instructor
   3. Regular checks of technicians
2. Field Procedure
   1. Two teams taking samples along same transect in different subplots
   2. Periodic duplicate sampling by professional
   3. Document variation in protocol
   4. Assurance of comparable habitats for ecosystem sampling
   5. Uniformity of method/effort across all samples
   6. Minimize chance of error in data sheet
3. Habitat Assessment
   1. Clear understanding of terms by each team
   2. Thorough training
4. Lab Procedures
   1. Instrument documentation and identification for sample analyzed
   2. Reference specimens with cross-check by professional
   3. Minimize chance of error in data sheets/tables
5. Data Analysis
   1. Plot and check for outliers
