What type of population monitoring method will be best for monitoring the species listed? is an appropriate method to monitor a population of swallows, while is an appropriate method to monitor a population of tortoises.

Point counts and line-transect  distance sampling methods are appropriate method to monitor a population of swallows and tortoises respectively.

Explanation:

Monitoring a population involves using field techniques methods for selection, to count, capture, observe, measure, mark individuals selected from the targeted population so that one can collect data that are needed to achieve study objectives at hand.

Point counts as a field techniques are commonly used to count or keep track of the fowls of the air (birds). Observation are made over a certain standardized period of time and record of the amounts birds from a single point is the routine.

While the field techniques known as line-transect distance sampling methods comes in handy for monitoring the tortoise population.

It shows how some individuals in a population go missing and allows for a concurrent working out of a method for controlling, tracking, marking measuring those number of individuals that is going missing.
